Scriptlet not printing JS and CSS file in Gsheet App Script [duplicate] - javascript
I have this form I created in HTML (called form.html) written in google apps script and I also have a stylesheet (CSS) to go with that. All is working well when I have the CSS in the same HTML-file as the form. However if I want to put my stylesheet in a separate HTML-file (called Stylesheet.html) and then include it in the form.html by using a scriplet
<?!= HtmlService.createHtmlOutputFromFile('Stylesheet').getContent(); ?>
or even creating an 'include' function:
function include(filename) {
return HtmlService.createHtmlOutputFromFile(filename)
.setSandboxMode(HtmlService.SandboxMode.IFRAME)
.getContent();
}
and then in form.html
<?!= include(Stylesheet) ?>
..it doesn't seem to work. What's even worse the scriplet shows up on the form.
Maybe there is something basic I am overlooking, but I can't wrap my head around this. Any ideas ?
Here is the code so far...
function doGet() {
return HtmlService.createHtmlOutputFromFile('Formulier')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
function include(filename) {
return HtmlService.createHtmlOutputFromFile(filename)
.setSandboxMode(HtmlService.SandboxMode.IFRAME)
.getContent();
}
function materiaalLijst(afdnum) {
return SpreadsheetApp.openById('1l6MKG61GHMFSZrOg04W4KChpb7oZBU9VKp42FPXmldc')
.getSheetByName('RESERVATIE')
.getDataRange()
.getValues()
.map(function (v) {
return v[Number(afdnum) - 1]
})
.splice(1);
}
//work in progress
function processForm(form) {
Logger (form); //array containing form elements
}
<style>

The result with CSS IN the form.html
and here is the CSS in a separate .html file and included
in form.html with
<?!= HtmlService.createHtmlOutputFromFile('Stylesheet').getContent(); ?>
You're doing this right:
Your css file must be an HTML file, as those are the only type supported by HtmlService. If you look at the starter scripts, you'll find that they have Stylesheet.html, with content:
<!-- This CSS package applies Google styling; it should always be included. -->
<link rel="stylesheet" href="https://ssl.gstatic.com/docs/script/css/add-ons1.css">
<style>
...
</style>
You know the google css is working if your sidebar or dialog looks pretty much like google stuff - same font, same text size. To have an action button be blue, you need to add the appropriate class to it, class="action".
Why isn't yours working?
Get ready for a face-palm moment...
You're using scriptlets, part of the Html Service templated HTML. They require interpretation, which is not done by HtmlService.createHtmlOutputFromFile(). (That's why you see the scriptlet line literally.)
Instead, you need to read the file containing scriptlets as a template, and then .evaluate() it.
function doGet() {
return HtmlService.createTemplateFromFile('form')
.evaluate()
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
To display the google-themed action button, include the Apps Script CSS and add "action" class:
<input type="submit" id="verzenden" name="verzenden" class="action verzenden" value="Reservatie verzenden" >
How about to name it Stylesheet.css?
And try to include it via normal HTML in the header.
<link rel="stylesheet" href="Stylesheet.css" type="text/css">

How can i wap the position of the label and the input tag with javascript?
I'm using elementor in wordpress, i'cant modify the html directly, so i need to swap both tags with javascript (or css if that's possible) in the form.
The code i'm using in CSS:
input:focus > .elementor-field-label {
border: 1px solid black !important;
border-radius: 5px;
transform: translate(0px, -20px);
font-size: 14px;
}
Won't work because of the position of the tags.
Then i tried this code in javascript to do the job:
$('label').each(function() {
$(this).insertAfter($(this).nextAll('input:first'));
});
But don't work.
So, how can i make this possible?
FIY:
The structure of this specific part of the form is this:
<div class="elementor-field-type-text elementor-field-group elementor-column elementor-field-group-name elementor-col-100 elementor-field-required"> /*Using just the elementor-field-group*/
<label for="form-field-name" class="elementor-field-label"> Texto </label>
<input size="1" type="text" name="form_fields[name]" id="form-field-name" class="elementor-field elementor-size-sm elementor-field-textual" required="required" aria-required="true">
</div>
With CSS you could do something like this:
.elementor-field-group {
display: flex;
flex-flow: column;
}
.elementor-field-group input {
order: -1;
}
This wouldn't change the HTML structure but visually they would swap position.
With Javascript you can do it like this:
document.querySelectorAll('.elementor-field-group label').forEach((e) => {
e.parentNode.appendChild(e)
})
This script just takes the label and appends it to the parent again, so it will be the last child of the wrapper.
Or this, to add the input element before the label. This would be the better solution, if there are more than those two elements inside of the wrapper.
document.querySelectorAll('.elementor-field-group input').forEach((e) => {
e.parentNode.insertBefore(e, e.previousElementSibling);
})
How do I duplicate a form in a div when I press a button?
I have an already existing form in my code which includes 2 text fields and a submit button. I have also added an “add” button which when clicked should add a new form below.How do I achieve this using Javascript. How do I add a new form by clicking on the add button?
you could use jquery $.clone() function so when you hit the button the form will be cloned and then $.append() to the parent div this will clone the form with the data , if you want something without the data you should clone the form in the start of the script.
You could use a templating engine like {{ mustache }} to create a form template and inject an auto-incrementing ID into it.
Note: If you want more logic, customization, or compiled templates, you can use handlebars.
var FORM_ID_INCR = 1; // Ever-increasing couter
document.getElementById('add-form-btn').addEventListener('click', function(e) {
createAndAppendNewContactForm();
});
function createAndAppendNewContactForm() {
let viewModel = { formId : FORM_ID_INCR++ };
let template = document.getElementById('form-template').innerHTML;
let renderedHtml = Mustache.render(template, viewModel);
let node = document.createRange().createContextualFragment(renderedHtml);
document.getElementById('form-container').appendChild(node);
}
.form-field {
margin-bottom: 0.5em;
}
.form-field label {
display: inline-block;
font-weight: bold;
width: 6em;
}
.contact-form {
border: 1px solid #DDD;
padding: 0.5em;
margin-bottom: 0.5em;
}
#form-container {
margin-bottom: 1em;
}

If you write a function that will turn the input values into a string that represents valid YAML text, you can use the Blob API to turn it into a file. As media type, use the same type as the other YAML files your company uses ( text/yaml, application/yaml, text/vnd.yaml, etc ) since we ( afaik ) do not have a standard type yet for YAML files. To actually save the file, you'll need to create a url from that Blob the user can click to download. ( See the multitude of other questions about that here on SO or any JS blob-to-url tutorial. ) If you are actually submitting a form to a serverside script, there's probably a bunch of server libraries that can create a YAML file you can return as the response to a form POST request.
Showing the contents of a SPAN using JavaScript
I have this code. I've done this for years now but I'm stumped with the result of this example. The purpose is to make the text box visible and put the contents of the clicked SPAN tag in it.
document.onclick = CaptureClickedElement;
function CaptureClickedElement(e)
{
var EventElement;
if(e==null)
EventElement = event.srcElement;// IE
else
EventElement = e.target;// Firefox
if( EventElement.tagName == "SPAN")
{
document.getElementById("divTXT").style.display="";
document.getElementById("txt").value = document.getElementById("Span1").innerHTML;
alert(document.getElementById("Span1").innerHTML)
}
}
Strangely though, it DOES show the contents but also shows open/close SPAN tags at the end of it. If I alert ther results, the same thing is shown.
Please find the attached screen shot of it here.
Does anyone have an idea of why this is happening?
Thanks!
Here is the HTML (copied from comments by mplungjan)
<style type="text/css">

</div>
</form>
</div>
<div id="divOuter">
<span id="Span1">hi, this is a test.<span>
</div>
</body>
Structure problem: <span id="Span1">hi, this is a test.<span> Note the absence of a proper close to the span.
Need to use .innerText (for IE) and .text for others.
input type=file show only button
Is there a way to style (or script) <input type=file /> element to have visible only "Browse" button without text field? Thanks Edit: Just to clarify why to I need this. I'm using multi file upload code from http://www.morningz.com/?p=5 and it doesn't need input text field because it never has value. Script just adds newly selected file to collection on page. It would look much better without text field, if it's possible.
<input type="file" id="selectedFile" style="display: none;" />
<input type="button" value="Browse..." onclick="document.getElementById('selectedFile').click();" />
This will surely work as I have used it in my projects.
I was having a heck of a time trying to accomplish this. I didn't want to use a Flash solution, and none of the jQuery libraries I looked at were reliable across all browsers.
I came up with my own solution, which is implemented completely in CSS (except for the onclick style change to make the button appear 'clicked').
You can try a working example here: http://jsfiddle.net/VQJ9V/307/ (Tested in FF 7, IE 9, Safari 5, Opera 11 and Chrome 14)
It works by creating a big file input (with font-size:50px), then wrapping it in a div that has a fixed size and overflow:hidden. The input is then only visible through this "window" div. The div can be given a background image or color, text can be added, and the input can be made transparent to reveal the div background:
HTML:
<div class="inputWrapper">
<input class="fileInput" type="file" name="file1"/>
</div>
CSS:
.inputWrapper {
height: 32px;
width: 64px;
overflow: hidden;
position: relative;
cursor: pointer;
/*Using a background color, but you can use a background image to represent a button*/
background-color: #DDF;
}
.fileInput {
cursor: pointer;
height: 100%;
position:absolute;
top: 0;
right: 0;
z-index: 99;
/*This makes the button huge. If you want a bigger button, increase the font size*/
font-size:50px;
/*Opacity settings for all browsers*/
opacity: 0;
-moz-opacity: 0;
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=0)
}
Let me know if there are any problems with it and I'll try to fix them.
I wasted my day today getting this to work. I found none of the solutions here working each of my scenarios.
Then I remembered I saw an example for the JQuery File Upload without text box. So what I did is that I took their example and stripped it down to the relevant part.
This solution at least works for IE and FF and can be fully styled. In the below example the file input is hidden under the fancy "Add Files" button.
<html>
<head>
<title>jQuery File Upload Example</title>
<style type="text/css">
.myfileupload-buttonbar input
{
position: absolute;
top: 0;
right: 0;
margin: 0;
border: solid transparent;
border-width: 0 0 100px 200px;
opacity: 0.0;
filter: alpha(opacity=0);
-o-transform: translate(250px, -50px) scale(1);
-moz-transform: translate(-300px, 0) scale(4);
direction: ltr;
cursor: pointer;
}
.myui-button
{
position: relative;
cursor: pointer;
text-align: center;
overflow: visible;
background-color: red;
overflow: hidden;
}
</style>
</head>
<body>
<div id="fileupload" >
<div class="myfileupload-buttonbar ">
<label class="myui-button">
<span >Add Files</span>
<input id="file" type="file" name="files[]" />
</label>
</div>
</div>
</body>
</html>
Add a label tag with for attribute assign the for attribute value to the file input button.
Now when you click the label, the browser will open up the file browse dialogue popup automatically.
Note: Hide the file input button using CSS.
Check the live demo below.
$('#imageUpload').change(function() {
readImgUrlAndPreview(this);
function readImgUrlAndPreview(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(e) {
$('#imagePreview').removeClass('hide').attr('src', e.target.result);
}
};
reader.readAsDataURL(input.files[0]);
}
});
.hide {
display: none;
}
.btn {
display: inline-block;
padding: 4px 12px;
margin-bottom: 0;
font-size: 14px;
line-height: 20px;
color: #333333;
text-align: center;
vertical-align: middle;
cursor: pointer;
border: 1px solid #ddd;
box-shadow: 2px 2px 10px #eee;
border-radius: 4px;
}
.btn-large {
padding: 11px 19px;
font-size: 17.5px;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
border-radius: 4px;
}
#imagePreview {
margin: 15px 0 0 0;
border: 2px solid #ddd;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div clas="file_input_wrap">
<input type="file" name="imageUpload" id="imageUpload" class="hide" />
<label for="imageUpload" class="btn btn-large">Select file</label>
</div>
<div class="img_preview_wrap">
<img src="" id="imagePreview" alt="Preview Image" width="200px" class="hide" />
</div>
Hide the input-file element and create a visible button that will trigger the click event of that input-file.
Try this:
CSS
#file { width:0; height:0; }
HTML:
<input type='file' id='file' name='file' />
<button id='btn-upload'>Upload</button>
JAVASCRIPT(jQuery):
$(function(){
$('#btn-upload').click(function(e){
e.preventDefault();
$('#file').click();}
);
});
I tried to implement the top two solutions, and it ended up being a HUGE waste of time for me. In the end, applying this .css class solved the problem...
input[type='file'] {
color: transparent;
}
Done! super clean and super simple...
That's going to be very hard. The problem with the file input type is that it usually consists of two visual elements, while being treated as a single DOM-element. Add to that that several browsers have their own distinct look and feel for the file input, and you're set for nightmare. See this article on quirksmode.org about the quirks the file input has. I guarantee you it won't make you happy (I speak from experience). [EDIT] Actually, I think you might get away with putting your input in a container element (like a div), and adding a negative margin to the element. Effectively hiding the textbox part off screen. Another option would be to use the technique in the article I linked, to try to style it like a button.
Fix to work in all browsers
RESOLVED:
<input type = "button" value = "Choose image"
onclick ="javascript:document.getElementById('imagefile').click();">
<input id = "imagefile" type="file" style='visibility: hidden;' name="img"/>
I have tested in FF, Chrome & IE - working fine, applied styles too :D
Here is my good ol' remedy:
<input type="file" id="myFile" style="display:none;" />
<button type="button" onclick="document.getElementById('myFile').click();">Browse</button>
At least it worked in Safari.
Plain and simple.
Another easy way of doing this. Make a "input type file" tag in html and hide it. Then click a button and format it according to need. After this use javascript/jquery to programmatically click the input tag when the button is clicked.
HTML :-
<input id="file" type="file" style="display: none;">
<button id="button">Add file</button>
JavaScript :-
document.getElementById('button').addEventListener("click", function() {
document.getElementById('file').click();
});
jQuery :-
$('#button').click(function(){
$('#file').click();
});
CSS :-
#button
{
background-color: blue;
color: white;
}
Here is a working JS fiddle for the same :- http://jsfiddle.net/32na3/
I used some of the code recommended above and after many hours of waisting my time, I eventually came to a css bag free solution.
You can run it over here - http://jsfiddle.net/WqGph/
but then found a better solution - http://jsfiddle.net/XMMc4/5/
<input type = "button" value = "Choose image #2"
onclick ="javascript:document.getElementById('imagefile').click();">
<input id = "imagefile" type="file" style='display:none;' name="img" value="none"/>see jsfiddle code for examples<br/>
You could label an image so when you click on it the click event of the button will be triggered. You can simply make the normal button invisible: <form> <label for="fileButton"><img src="YourSource"></label> <!--You don't have to put an image here, it can be anything you like--> <input type="file" id="fileButton" style="display:none;"/> </form> It worked for me on all browsers, and is very easy to use.
You can dispatch the click event on a hidden file input like this:
<form action="#type your action here" method="POST" enctype="multipart/form-data">
<div id="yourBtn" style="height: 50px; width: 100px;border: 1px dashed #BBB; cursor:pointer;" >Click to upload!</div>
<!-- hide input[type=file]!-->
<div style='height: 0px;width:0px; overflow:hidden;'><input id="upfile" type="file" value="upload"/></div>
<input type="submit" value='submit' >
</form>
<script type="text/javascript">
var btn = document.getElementById("yourBtn");
var upfile = document.getElementById("upfile");
btn.addEventListener('click',function(){
if(document.createEvent){
var ev = document.createEvent('MouseEvents');
ev.initEvent('click',true,false);
upfile.dispatchEvent(ev);
}else{
upfile.click();
}
});
</script>
HTML:
<input type="file" name="upload" id="upload" style="display:none"></input>
<button id="browse">Upload</button>
JQUERY
$(document).ready(function(){
$("#browse").click(function(){
$("#upload").click();
});
});
Hope this works :)
This HTML code show up only Upload File button
<form action="/action_page.php">
<input type="button" id="id" value="Upload File" onclick="document.getElementById('file').click();" />
<input type="file" style="display:none;" id="file" name="file" onchange="this.form.submit()"/>
</form>
You can give the input element a font opacity of 0. This will hide the text field without hiding the 'Choose Files' button.
No javascript required, clear cross browser as far back as IE 9
E.g.,
input {color: rgba(0, 0, 0, 0);}
Ive a really hacky solution with this...
<style type="text/css">
input[type="file"]
{
width: 80px;
}
</style>
<input id="File1" type="file" />
The problem is the width attribute that is hiding the text field will obvously vary between browsers, vary between Windows XP themes and so on. Maybe its something you can work with though?...
I know this is an old post but a simple way to make the text dissapear is just to set text color to that of your background.
eg if your text input background is white then:
input[type="file"]{
color:#fff;
}
This will not effect the Choose File text which will still be black due to the browser.
There is a simple and hacky way to show only the file input button while keeping the render and translations of this file input button : Make the text that is displayed after a file input invisible using a the color transparent. <input type="file" style="color: transparent" />
my solution is just to set it within a div like "druveen" said, however i ad my own button style to the div (make it look like a button with a:hover) and i just set the style "opacity:0;" to the input. Works a charm for me, hope it does the same for you.
This works for me:
input[type="file"] {
color: white!important;
}
I just styled an input file with width: 85px, and the text field disappeared at all
Select Logo <input type="file" id="logo">
$("#logo").css('opacity','0');
$("#select_logo").click(function(){
$().trigger('click');
return false;
});
For me, the simplest way is using a font color like background color. Simple, not elegant, but usefull. <div style="color:#FFFFFF"> <!-- if background page is white, of course --> <input class="fileInput" type="file" name="file1"/></div>
So here's the best way to do this FOR ALL BROWSERS:
Forget CSS!
<p>Append Image:</p>
<input type="button" id="clickImage" value="Add Image" />
<input type="file" name="images[]" id="images" multiple />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" charset="utf-8"></script>

$('#images').hide();
$('#clickImage').click( function() {
$('#images').trigger('click');
});
</script>
All these answers are cute, but CSS won't work since it isn't the same across all browsers and devices, the first answer I wrote will work in everything but Safari. To get it to work accross all browsers all the time it must be created dynamically and recreated every time you want to clear the input text:
var imageDiv = document.createElement("div");
imageDiv.setAttribute("id", "imagediv");
imageDiv.style.cssText = 'position:relative; vertical-align: bottom;';
var imageText = document.createTextNode("Append Image:");
var newLine = document.createElement("br");
var image = document.createElement("input");
image.setAttribute("type", "file");
image.setAttribute("id", "images");
image.setAttribute("name", "images[]");
image.setAttribute("multiple", "multiple");
imageDiv.appendChild(imageText);
imageDiv.appendChild(newLine);
imageDiv.appendChild(image);
questionParagraph.appendChild(imageDiv);
The answer of tmanthey is quite good, except that you can't play with border-width in Firefox v20. If you see the link (demo, can't really show here) they solved the problem using font-size=23px, transform:translate(-300px, 0px) scale(4) for Firefox to get the button bigger. Other solutions using .click() on a different div is useless if you want to make it a drag'n'drop input box.
There are several valid options here but thought I would give what I have come up with while trying to fix a similar issue. http://jsfiddle.net/5RyrG/1/
<span class="btn fileinput-button">
<span>Import Field(s)</span>
<input id="fileupload" type="file" name="files[]" onchange="handleFiles(this.files)" multiple>
</span>
<div id="txt"></div>
function handleFiles(files){
$('#txt').text(files[0].name);
}
I wrote this:
<form action='' method='POST' name='form-upload-image' id='form-upload-image' enctype='multipart/form-data'>
<div style="width: 0; height: 0; overflow: hidden;">
<input type="file" name="input-file" id="input-file" onchange="this.files.length > 0 ? document.getElementById('form-upload-image').submit():null;" />
</div>
</form>
<img src="image.jpg" style="cursor: pointer;" onclick="document.getElementById('input-file').click();" />
Work fine in all browsers, no jQuery, no CSS.
Here is a simplified version of #ampersandre's popular solution that works in all major browsers.
Asp.NET markup
<asp:TextBox runat="server" ID="FilePath" CssClass="form-control"
style="float:left; display:inline; margin-right:5px; width:300px"
ReadOnly="True" ClientIDMode="Static" />
<div class="inputWrapper">
<div id="UploadFile" style="height:38px; font-size:16px;
text-align:center">Upload File</div>
<div>
<input name="FileUpload" id="FileInput" runat="server"
type="File" />
</div>
</div>
<asp:Button ID="UploadButton" runat="server"
style="display:none" OnClick="UploadButton_Click" />
</div>
<asp:HiddenField ID="hdnFileName" runat="server" ClientIDMode="Static" />
JQuery Code
$(document).ready(function () {
$('#UploadFile').click(function () {
alert('UploadFile clicked');
$('[id$="FileInput"]').trigger('click');
});
$('[id$="FileInput"]').change(function (event) {
var target = event.target;
var tmpFile = target.files[0].name;
alert('FileInput changed:' + tmpFile);
if (tmpFile.length > 0) {
$('#hdnFileName').val(tmpFile);
}
$('[id$="UploadButton"]').trigger('click');
});
});
css code
.inputWrapper {
height: 38px;
width: 102px;
overflow: hidden;
position: relative;
padding: 6px 6px;
cursor: pointer;
white-space:nowrap;
/*Using a background color, but you can use a background image to represent
a button*/
background-color: #DEDEDE;
border: 1px solid gray;
border-radius: 4px;
-moz-user-select: none;
-ms-user-select: none;
-webkit-user-select: none;
user-select: none;
}
Uses a hidden "UploadButton" click trigger for server postback with standard . The with "Upload File" text pushes the input control out of view in the wrapper div when it overflows so there is no need to apply any styles for the "file input" control div. The $([id$="FileInput"]) selector allows section of ids with standard ASP.NET prefixes applied. The FilePath textbox value in set from server code behind from hdnFileName.Value once file is uploaded.
