I have the following html code:
<!DOCTYPE html>
<html>
<body>
<p>don't print this to pdf</p>
<div id="pdf">
<p><font size="3" color="red">print this to pdf</font></p>
</div>
</body>
</html>
All I want to do is to print to pdf whatever is found in the div with an id of "pdf". This must be done using JavaScript. The "pdf" document should then be automatically downloaded with a filename of "foobar.pdf"
I've been using jspdf to do this, but the only function it has is "text" which accepts only string values. I want to submit HTML to jspdf, not text.
jsPDF is able to use plugins. In order to enable it to print HTML, you have to include certain plugins and therefore have to do the following:
Go to https://github.com/MrRio/jsPDF and download the latest Version.
Include the following Scripts in your project:
jspdf.js
jspdf.plugin.from_html.js
jspdf.plugin.split_text_to_size.js
jspdf.plugin.standard_fonts_metrics.js
If you want to ignore certain elements, you have to mark them with an ID, which you can then ignore in a special element handler of jsPDF. Therefore your HTML should look like this:
<!DOCTYPE html>
<html>
<body>
<p id="ignorePDF">don't print this to pdf</p>
<div>
<p><font size="3" color="red">print this to pdf</font></p>
</div>
</body>
</html>
Then you use the following JavaScript code to open the created PDF in a PopUp:
var doc = new jsPDF();
var elementHandler = {
'#ignorePDF': function (element, renderer) {
return true;
}
};
var source = window.document.getElementsByTagName("body")[0];
doc.fromHTML(
source,
15,
15,
{
'width': 180,'elementHandlers': elementHandler
});
doc.output("dataurlnewwindow");
For me this created a nice and tidy PDF that only included the line 'print this to pdf'.
Please note that the special element handlers only deal with IDs in the current version, which is also stated in a GitHub Issue. It states:
Because the matching is done against every element in the node tree, my desire was to make it as fast as possible. In that case, it meant "Only element IDs are matched" The element IDs are still done in jQuery style "#id", but it does not mean that all jQuery selectors are supported.
Therefore replacing '#ignorePDF' with class selectors like '.ignorePDF' did not work for me. Instead you will have to add the same handler for each and every element, which you want to ignore like:
var elementHandler = {
'#ignoreElement': function (element, renderer) {
return true;
},
'#anotherIdToBeIgnored': function (element, renderer) {
return true;
}
};
From the examples it is also stated that it is possible to select tags like 'a' or 'li'. That might be a little bit to unrestrictive for the most usecases though:
We support special element handlers. Register them with jQuery-style
ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)
There is no support for any other type of selectors (class, of
compound) at this time.
One very important thing to add is that you lose all your style information (CSS). Luckily jsPDF is able to nicely format h1, h2, h3 etc., which was enough for my purposes. Additionally it will only print text within text nodes, which means that it will not print the values of textareas and the like. Example:
<body>
<ul>
<!-- This is printed as the element contains a textnode -->
<li>Print me!</li>
</ul>
<div>
<!-- This is not printed because jsPDF doesn't deal with the value attribute -->
<input type="textarea" value="Please print me, too!">
</div>
</body>
This is the simple solution. This works for me. You can use the javascript print concept and simple save this as pdf.
<html xmlns="http://www.w3.org/1999/xhtml">

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">

No depenencies, pure JS
To add CSS or images - do not use relative URLs, use full URLs http://...domain.../path.css or so. It creates separate HTML document and it has no context of main thing.
you can also embed images as base64
This served me for years now:
export default function printDiv({divId, title}) {
let mywindow = window.open('', 'PRINT', 'height=650,width=900,top=100,left=150');
mywindow.document.write(`<html><head><title>${title}</title>`);
mywindow.document.write('</head><body >');
mywindow.document.write(document.getElementById(divId).innerHTML);
mywindow.document.write('</body></html>');
mywindow.document.close(); // necessary for IE >= 10
mywindow.focus(); // necessary for IE >= 10*/
mywindow.print();
mywindow.close();
return true;
}
Of course this will open print dialog and user will have to know she/he can select print to pdf option, to get pdf. There may be printer pre-selected and if user confirms may get this document actually printed. To avoid such situation and to provide PDF without any extras, you need to make PDF file. Probably on the server side. You could have tiny html page with invoice only and convert it to PDF file with headless chrome. It's super easy with puppeteer. No need to install/config chrome, just install npm package puppeteer (managed by chrome team) and run it. Keep in mind this will actually launch real chrome just w/o GUI, so you need to have some RAM & CPU for this. Most servers will be fine with low enough traffic. Here is code sample but this must run on the BACKEND. Nodejs. Also it's slow call, it's resources intensive call. You should run it NOT on api call but e.g. after invoice was created - create pdf for it and store, if pdf was not generated yet, just show message to try again in couple minutes.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://your-domain.com/path-to-invoice', {
waitUntil: 'networkidle2',
});
await page.pdf({ path: 'invoice-file-path.pdf', format: 'a4' });
await browser.close();
})();
Learn more here: https://pptr.dev/
if you need to downloadable pdf of a specific page just add button like this
<h4 onclick="window.print();"> Print </h4>
use window.print() to print your all page not just a div
You can use autoPrint() and set output to 'dataurlnewwindow' like this:
function printPDF() {
var printDoc = new jsPDF();
printDoc.fromHTML($('#pdf').get(0), 10, 10, {'width': 180});
printDoc.autoPrint();
printDoc.output("dataurlnewwindow"); // this opens a new popup, after this the PDF opens the print window view but there are browser inconsistencies with how this is handled
}
As mentioned, you should use jsPDF and html2canvas. I've also found a function inside issues of jsPDF which splits automatically your pdf into multiple pages (sources)
function makePDF() {
var quotes = document.getElementById('container-fluid');
html2canvas(quotes, {
onrendered: function(canvas) {
//! MAKE YOUR PDF
var pdf = new jsPDF('p', 'pt', 'letter');
for (var i = 0; i <= quotes.clientHeight/980; i++) {
//! This is all just html2canvas stuff
var srcImg = canvas;
var sX = 0;
var sY = 980*i; // start 980 pixels down for every new page
var sWidth = 900;
var sHeight = 980;
var dX = 0;
var dY = 0;
var dWidth = 900;
var dHeight = 980;
window.onePageCanvas = document.createElement("canvas");
onePageCanvas.setAttribute('width', 900);
onePageCanvas.setAttribute('height', 980);
var ctx = onePageCanvas.getContext('2d');
// details on this usage of this function:
// https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Using_images#Slicing
ctx.drawImage(srcImg,sX,sY,sWidth,sHeight,dX,dY,dWidth,dHeight);
// document.body.appendChild(canvas);
var canvasDataURL = onePageCanvas.toDataURL("image/png", 1.0);
var width = onePageCanvas.width;
var height = onePageCanvas.clientHeight;
//! If we're on anything other than the first page,
// add another page
if (i > 0) {
pdf.addPage(612, 791); //8.5" x 11" in pts (in*72)
}
//! now we declare that we're working on that page
pdf.setPage(i+1);
//! now we add content to that page!
pdf.addImage(canvasDataURL, 'PNG', 20, 40, (width*.62), (height*.62));
}
//! after the for loop is finished running, we save the pdf.
pdf.save('test.pdf');
}
});
}
i use jspdf and html2canvas for css rendering and i export content of specific div as this is my code
$(document).ready(function () {
let btn=$('#c-oreder-preview');
btn.text('download');
btn.on('click',()=> {
$('#c-invoice').modal('show');
setTimeout(function () {
html2canvas(document.querySelector("#c-print")).then(canvas => {
//$("#previewBeforeDownload").html(canvas);
var imgData = canvas.toDataURL("image/jpeg",1);
var pdf = new jsPDF("p", "mm", "a4");
var pageWidth = pdf.internal.pageSize.getWidth();
var pageHeight = pdf.internal.pageSize.getHeight();
var imageWidth = canvas.width;
var imageHeight = canvas.height;
var ratio = imageWidth/imageHeight >= pageWidth/pageHeight ? pageWidth/imageWidth : pageHeight/imageHeight;
//pdf = new jsPDF(this.state.orientation, undefined, format);
pdf.addImage(imgData, 'JPEG', 0, 0, imageWidth * ratio, imageHeight * ratio);
pdf.save("invoice.pdf");
//$("#previewBeforeDownload").hide();
$('#c-invoice').modal('hide');
});
},500);
});
});
One way is to use window.print() function. Which does not require any library
Pros
1.No external library require.
2.We can print only selected parts of body also.
3.No css conflicts and js issues.
4.Core html/js functionality
---Simply add below code
CSS to
#media print {
body * {
visibility: hidden; // part to hide at the time of print
-webkit-print-color-adjust: exact !important; // not necessary use
if colors not visible
}
#printBtn {
visibility: hidden !important; // To hide
}
#page-wrapper * {
visibility: visible; // Print only required part
text-align: left;
-webkit-print-color-adjust: exact !important;
}
}
JS code - Call bewlow function on btn click
$scope.printWindow = function () {
window.print()
}
Note: Use !important in every css object
Example -
.legend {
background: #9DD2E2 !important;
}
Use pdfMake.js and this Gist.
(I found the Gist here along with a link to the package html-to-pdfmake, which I end up not using for now.)
After npm install pdfmake and saving the Gist in htmlToPdf.js I use it like this:
const pdfMakeX = require('pdfmake/build/pdfmake.js');
const pdfFontsX = require('pdfmake-unicode/dist/pdfmake-unicode.js');
pdfMakeX.vfs = pdfFontsX.pdfMake.vfs;
import * as pdfMake from 'pdfmake/build/pdfmake';
import htmlToPdf from './htmlToPdf.js';
var docDef = htmlToPdf(`<b>Sample</b>`);
pdfMake.createPdf({content:docDef}).download('sample.pdf');
Remarks:
My use case is to create the relevant html from a markdown document (with markdown-it) and subsequently generating the pdf, and uploading its binary content (which I can get with pdfMake's getBuffer() function), all from the browser. The generated pdf turns out to be nicer for this kind of html than with other solutions I have tried.
I am dissatisfied with the results I got from jsPDF.fromHTML() suggested in the accepted answer, as that solution gets easily confused by special characters in my HTML that apparently are interpreted as a sort of markup and totally mess up the resulting PDF.
Using canvas based solutions (like the deprecated jsPDF.from_html() function, not to be confused with the one from the accepted answer) is not an option for me since I want the text in the generated PDF to be pasteable, whereas canvas based solutions generate bitmap based PDFs.
Direct markdown to pdf converters like md-to-pdf are server side only and would not work for me.
Using the printing functionality of the browser would not work for me as I do not want to display the generated PDF but upload its binary content.
I was able to get jsPDF to print dynamically created tables from a div.
$(document).ready(function() {
$("#pdfDiv").click(function() {
var pdf = new jsPDF('p','pt','letter');
var specialElementHandlers = {
'#rentalListCan': function (element, renderer) {
return true;
}
};
pdf.addHTML($('#rentalListCan').first(), function() {
pdf.save("caravan.pdf");
});
});
});
Works great with Chrome and Firefox... formatting is all blown up in IE.
I also included these:
<script src="js/jspdf.js"></script>
<script src="js/jspdf.plugin.from_html.js"></script>
<script src="js/jspdf.plugin.addhtml.js"></script>
<script src="//mrrio.github.io/jsPDF/dist/jspdf.debug.js"></script>

If you want to export a table, you can take a look at this export sample provided by the Shield UI Grid widget.
It is done by extending the configuration like this:
...
exportOptions: {
proxy: "/filesaver/save",
pdf: {
fileName: "shieldui-export",
author: "John Smith",
dataSource: {
data: gridData
},
readDataSource: true,
header: {
cells: [
{ field: "id", title: "ID", width: 50 },
{ field: "name", title: "Person Name", width: 100 },
{ field: "company", title: "Company Name", width: 100 },
{ field: "email", title: "Email Address" }
]
}
}
}
...
This example works great.
<button onclick="genPDF()">Generate PDF</button>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.min.js"></script>
<script>
function genPDF() {
var doc = new jsPDF();
doc.text(20, 20, 'Hello world!');
doc.text(20, 30, 'This is client-side Javascript, pumping out a PDF.');
doc.addPage();
doc.text(20, 20, 'Do you like that?');
doc.save('Test.pdf');
}
</script>
Dissatisfied with the rendering of html2canvas and lack of modern CSS3/JS and print specific CSS support of pdfMake's outdated version of WebKit...
Here's a theoretical solution, it's headless and can render pages faithfully, supports page breaks, margins, different page sizes and can be automated. You can even render WebGl to PDF.
Chrome has a devtools protocol... which has a printtoPDF function
Excerpt: https://gitlab.com/-/snippets/new
Official 20k-SLOC spec: https://github.com/ChromeDevTools/devtools-protocol/blob/master/json/browser_protocol.json
You can use node and https://github.com/GoogleChrome/chrome-launcher to run chrome headless... wait for it to render.
Profit
printToPDF command you'd run on chrome_devtools protocol:
printToPDF({
printBackground: false,
pageWidth: 8.5,
pageHeight: 11,
transferMode: "ReturnAsStream" // or ReturnAsBase64
})
2022 Answer:
To generate PDF from HTML Element and prompt to save file:
import { jsPDF } from "jsPDF"
function generatePDF() {
const doc = new jsPDF({ unit: 'pt' }) // create jsPDF object
const pdfElement = document.getElementById('pdf') // HTML element to be converted to PDF
doc.html(pdfElement, {
callback: (pdf) => {
pdf.save('MyPdfFile.pdf')
},
margin: 32, // optional: page margin
// optional: other HTMLOptions
})
}
<button onclick="generatePDF()">Save PDF</button>
...
To preview PDF without printing:
doc.html(pdfElement, {
callback: (pdf) => {
const myPdfData = pdf.output('datauristring')
}
})
<embed type="application/pdf" src={myPdfData} />
...

To capture div as PDF you can use https://grabz.it solution. It's got a JavaScript API which is easy and flexible and will allow you to capture the contents of a single HTML element such as a div or a span
In order to implement it you will need to first get an app key and secret and download the (free) SDK.
And now an example.
Let's say you have the HTML:
<div id="features">
<h4>Acme Camera</h4>
<label>Price</label>$399<br />
<label>Rating</label>4.5 out of 5
</div>
<p>Cras ut velit sed purus porttitor aliquam. Nulla tristique magna ac libero tempor, ac vestibulum felisvulput ate. Nam ut velit eget
risus porttitor tristique at ac diam. Sed nisi risus, rutrum a metus suscipit, euismod tristique nulla. Etiam venenatis rutrum risus at
blandit. In hac habitasse platea dictumst. Suspendisse potenti. Phasellus eget vehicula felis.</p>
To capture what is under the features id you will need to:
//add the sdk
<script type="text/javascript" src="grabzit.min.js"></script>
<script type="text/javascript">
//login with your key and secret.
GrabzIt("KEY", "SECRET").ConvertURL("http://www.example.com/my-page.html",
{"target": "#features", "format": "pdf"}).Create();
</script>
Please note the target: #feature. #feature is you CSS selector, like in the previous example. Now, when the page is loaded an image screenshot will now be created in the same location as the script tag, which will contain all of the contents of the features div and nothing else.
The are other configuration and customization you can do to the div-screenshot mechanism, please check them out here
The following method works fine for my case.
Hide additional parts for a page like the following example
#media print{
body{
-webkit-print-color-adjust: exact; // if you want to enable graphics
color-adjust: exact !important; // if you want to enable graphics
print-color-adjust: exact !important; // if you want to enable graphics
* {
visibility: hidden;
margin:0;
padding:0
}
.print_area, .print_area *{
visibility: visible;
}
.print_area{
margin: 0;
align: center;
}
.pageBreak {
page-break-before : always; // If you want to skip next page
page-break-inside: avoid; // If you want to skip next page
}
}
#page {
size: A4; margin:0mm; // set page layout
background-color: #fff;
}
}
Use the javascript print function to print execution.
<button onclick="window.print()">Print</button>
any one try this
(function () {
var
form = $('.form'),
cache_width = form.width(),
a4 = [595.28, 841.89]; // for a4 size paper width and height
$('#create_pdf').on('click', function () {
$('body').scrollTop(0);
createPDF();
});
//create pdf
function createPDF() {
getCanvas().then(function (canvas) {
var
img = canvas.toDataURL("image/png"),
doc = new jsPDF({
unit: 'px',
format: 'a4'
});
doc.addImage(img, 'JPEG', 20, 20);
doc.save('Bhavdip-html-to-pdf.pdf');
form.width(cache_width);
});
}
// create canvas object
function getCanvas() {
form.width((a4[0] * 1.33333) - 80).css('max-width', 'none');
return html2canvas(form, {
imageTimeout: 2000,
removeContainer: true
});
}
}());
I am exporting the content on the webpage to the PDF file, for this i have used jsPDF API and i could able to get it work but now i want to use html2PDF as it resolves few issues which were faced when using jsPDF API.
I have written the function $scope.exportUsingJSPDF which is called when the button Export Using JSPDF is clicked. Similarly i want to implement the function $scope.exportUsingHTML2PDF which uses html2PDF API but could not succeed. Any inputs on how to modify $scope.exportUsingHTML2PDF so that it iterates the divs and shows the div content as shown when invoked using $scope.exportUsingJSPDF by clicking Export using JSPDF API.
Complete online example: https://plnkr.co/edit/454HUFF3rmLlkXLCQkbx?p=preview
js code:
//trying to implement the below function same as $scope.exportUsingJSPDF, so
// that when user click on Export using HTML2PDF button, it exports the content to the PDF and generaes the PDF.
$scope.exportUsingHTML2PDF = function(){
var pdf = new jsPDF('l', 'pt', 'a4');
var pdfName = 'test.pdf';
pdf.canvas.height = 72 * 11;
pdf.canvas.width = 72 * 8.5;
html2pdf(document.getElementByClassName("myDivClass"), pdf, function(pdf){
pdf.save(pdfName);
});
}
$scope.exportUsingJSPDF = function() {
var pdf = new jsPDF('p','pt','a4');
var pdfName = 'test.pdf';
var options = { pagesplit: true};
var $divs = $('.myDivClass') //jQuery object of all the myDivClass divs
var numRecursionsNeeded = $divs.length -1; //the number of times we need to call addHtml (once per div)
var currentRecursion=0;
//Found a trick for using addHtml more than once per pdf. Call addHtml in the callback function of addHtml recursively.
function recursiveAddHtmlAndSave(currentRecursion, totalRecursions){
//Once we have done all the divs save the pdf
if(currentRecursion==totalRecursions){
pdf.save(pdfName);
}else{
currentRecursion++;
pdf.addPage();
//$('.myDivClass')[currentRecursion] selects one of the divs out of the jquery collection as a html element
//addHtml requires an html element. Not a string like fromHtml.
pdf.fromHTML($('.myDivClass')[currentRecursion], 15, 20, options, function(){
console.log(currentRecursion);
recursiveAddHtmlAndSave(currentRecursion, totalRecursions)
});
}
}
pdf.fromHTML($('.myDivClass')[currentRecursion], 15, 20, options, function(){
recursiveAddHtmlAndSave(currentRecursion, numRecursionsNeeded);
});
}
PS: I was trying to modify $scope.exportUsingHTML2PDF so that it gives the same output as generated when clicked on "Export using JSPDF" button which calls the function $scope.exportUsingJSPDF.
The problem lies with your function using exportUsingHTML2PDF, the error is that you need to pass in the html to the function of html2PDF. Manage the page css on the basis of your need.
EDIT: You have wrong library. Please check html2pdf.js library within the plunker
Working plunker: html2pdf
$scope.exportUsingHTML2PDF = function() {
var element = document.getElementById('element-to-print');
html2pdf(element, {
margin: 1,
filename: 'myfile.pdf',
image: {
type: 'jpeg',
quality: 0.98
},
html2canvas: {
dpi: 192,
letterRendering: true
},
jsPDF: {
unit: 'in',
format: 'letter',
orientation: 'portrait'
}
});
}
With JSPDF and HTML2PDF, you have to get used to two fundamentally different coding styles:
JSPDF: imperative (javascript statements)
HTML2PDF: declarative (directives embedded in HTML)
So for page breaks:
JSPDF: pdf.addPage();
HTML2PDF: <div class="html2pdf__page-break"></div>
That should work, however HTML2PDF is buggy and gives a "Supplied data is not a JPEG" error when <div class="html2pdf__page-break"></div> is included (at least it does so for me, in Plunkr), despite being totally what the documentation tells us to do.
I haven't got time to debug it. You'll need to do some research. Someone will have posted a solution somewhere on the web.
I am trying to get the Camera API to work in my PhoneGap android app, but i keep getting this error
"Cannot read property 'getPicture' of undefined".
Now i have checked countless answers on StackOverflow and tutorials all over the web,and tried all the answer there(with no luck), and i cant seem to find the issue.
This is the button that calls the function
<button type="button" class="btn btn-primary" ng-click="getPic()">Camera</button>
This is the controller that handles the camera
myApp.controller('EditProfileCtrl', function ($scope, $http, navigateFactory) {
$scope.getPic = function () {
navigator.camera.getPicture(onSuccess, onFail, {
quality: 60,
destinationType: Camera.DestinationType.DATA_URL,
sourceType: 1
});
function onSuccess(imageData) {
var image = document.getElementById('myImage');
image.src = "data:image/jpeg;base64," + imageData;
}
function onFail(message) {
alert('Failed beause' + message);
}
};
});
Please comment if there is any additional information required.
Any and all help will be hugely appreciated.
EDIT: So after following Aravin's advice i added <script src="cordova.js"></script>
now it atleast looks like something is happening, but now im getting these errors in my eclipse logcat:
I/System.out(3871): Error adding plugin
org.apache.cordova.CameraLauncher D/PluginManager(3871): exec() call

The total work around is below..
you need to write all code in your html page.
<body>
<div data-role="page">
<script type="text/javascript">
function getPhotoFromCamera() {
navigator.camera.getPicture(onPhotoDataSuccess, onFail, {

}
function onPhotoDataSuccess(imageData){
var image = document.getElementById('image');
image.style.display = 'block';
image.src = "data:image/jpeg;base64,"+imageData;

If you are using TFS, remember to check out for edit "fetch.json" before installing the plugin, or it will fail mid-installation.
So after trying all the things here with no success I did this which fixed the issue (dont know how)...
remove the plugin , build , add the plugin , build
and Magic!
How to choose or pick multiple images at the same time in phonegap camera API when using Camera.DestinationType.FILE_URI. I am able to pick only one images at a time. I am able to pick multiple files(including txt,pdf..) in sdcard using this. So i want same like for images.
navigator.camera.getPicture(function(imageData) {
window.resolveLocalFileSystemURI(imageData, function(fileEntry) {
fileEntry.file(function(fileObj) {
}, onFail, {
quality : 50,
destinationType : Camera.DestinationType.FILE_URI
});
My cordova version 3.3, Jquery Mobile 1.3.2.
Please suggest any plugins are available to do this.
Use this Cordova multiple image selector plugin to choose multiple image at a time. It is good plugin for choose multiple images.
Download the above plugin and copy paste the java classes. Set the required permission. Don't forget to copy the res folder just copy and paste in your res folder.
Inside assets/www create imagepicker.js copy and paste the dowloaded imagepicker.js
In your index.html set like this:
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="imagepicker.js"></script>
<script type="text/javascript">
document.addEventListener("deviceready",onDeviceReady,false);
function onDeviceReady(){
window.imagePicker.getPictures(
function(results) {
for (var i = 0; i < results.length; i++) {
alert('Image URI: ' + results[i]);
// read file type and size and file name like below(in comment)
/* window.resolveLocalFileSystemURI(results[i], function(fileEntry){
fileEntry.file(function(fileObj) {
alert(fileEntry.name);
alert(fileObj.size);
alert(fileObj.type);
});
}, function (error) {
alert('Error: ' + error);
});*/
}
}, function (error) {
alert('Error: ' + error);
}
);
}
</script>
Note: This should work only cordova 3.0 and above and android 4.0 and above
Open CameraLauncher.java file and replace these lines
String resizePath = getTempDirectoryPath() + "/resize.jpg";
this.callbackContext.success("file://" + resizePath + "?" + System.currentTimeMillis());
to
String resizePath = getTempDirectoryPath() + "/resize"+System.currentTimeMillis()+".jpg";
this.callbackContext.success("file://" + resizePath);
var x=0;
function onPhotoDataSuccess(imageURI)
{
x++;
// Uncomment to view the base64-encoded image data
console.log(imageURI);
alert(imageURI);
// Get image handle
//
var y = 'smallImage'+x;
var smallImage = document.getElementById(y);
alert(smallImage);
smallImage.src = "data:image/jpeg;base64," + imageURI;
// Unhide image elements
//
smallImage.style.display = 'block';
// Show the captured photo
// The in-line CSS rules are used to resize the image
//
//var fso=new ActiveXObject("Scripting.FileSystemObject");
//fso.CopyFile("data:image/jpeg;base64," + imageURI,"file:///storage/sdcard/DCIM/");
alert(smallImage.src)
}
where x is the loop for doing the multiple image from camera as well as from photogallery
When I run the app on the device I get no error (well nothing occurs at all) as there is no debug console but when I run the app in the browser I get "Titanium is not defined"
Is there a js file I need to include?
I got the camera code from here:
http://www.mindfiresolutions.com/Capture-Image-with-device-camera-in-IPhoneAndroid-application-using-Titanium-1912.php
I call it from an html file from webview.
I created a new project from scratch and I get he same error. This is so frustrating:
in html:
<!doctype html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width;initial-scale=1.0 maximum-scale=1.0; user scalable=0;">
<title>Notes</title>
<script language="JavaScript" type="text/javascript">
function play(locid) {
Ti.App.fireEvent('play', {
locid : locid
});
}
</script>
</head>
<body>
<a id="Home" onclick ="play(125)" title = "" > hello </a>
</body>
</html>
in app.js:
Ti.App.addEventListener('play', function(e)
{
alert(e.locid);
});
Uncaught ReferenceError: Ti is not defined in the HTML file!!!
That code has a number of things preventing it from working as a standalone app.js. I want to address a couple of the concerns brought up by it, and then I'll directly address the app.js so you can get on your way.
First, "Ti.UI.currentWindow" is how you get a reference to a window in a situation like this:
In the file "app.js", you have:
var win = Ti.UI.createWindow({
url: 'win.js'
});
win.open();
And in "win.js", you have:
var win = Ti.UI.currentWindow;
win.add(Ti.UI.createLabel({
text: 'Hello, world!', textAlign: 'center',
color: '#000'
}));
But structuring your apps like that isn't the recommended approach anymore. If you're starting fresh, start right -- with Alloy. http://docs.appcelerator.com/titanium/3.0/#!/guide/Alloy_Quick_Start
If all you really care about is getting the example to work, below is the code updated to work:
//Define the current window
var myWin = Ti.UI.createWindow({
backgroundColor: 'white'
});
//Define the button to activate camera
var cameraBtn = Ti.UI.createButton({
title: 'Click to activate Camera',
top: 10 //Set the button position on the screen
});
cameraBtn.addEventListener('click', function () {
//Activate camera
Ti.Media.showCamera({
success: function (event) {
//Holds the captured image
var capturedImg = event.media;
// Condition to check the selected media
if (event.mediaType == Ti.Media.MEDIA_TYPE_PHOTO) {
//Define an image view with captured image
var imgView = Ti.UI.createImageView({
left: 10,
width: 250,
height: 250,
image: capturedImg //Set captured image
});
//Add the image to window for displaying
myWin.add(imgView);
}
},
cancel: function () {
//While cancellation of the process
},
error: function (error) {
// If any error occurs during the process
}
});
});
myWin.add(cameraBtn);
myWin.open();
use "Titanium" instead of "Ti" in WebView HTML code.
