I'm using PhoneGap to develop an android app. in the index.html I load a js file like this:
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="styles/style.css" />
<link rel="stylesheet" href="styles/loading.css" />
<script src="scripts/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="scripts/cordova-2.5.0.js"></script>
<script type="text/javascript" src="scripts/readImages.js"></script>
<script type="text/javascript">
function onReadImage(event) {
//do something
}
document.addEventListener("onReadImage", onReadImage, false);
</script>
</head>
<body>
<!--
.....
-->
</body>
</html>
readImages.js
// Some codes
window.readImageEvent= document.createEvent("readImageEvent"); // line 4
readImageEvent.initEvent("onWeddingCakesRead", true, true);
//Some functions
readImageEvent.images = data;
document.dispatchEvent(readImageEvent);
but when I check LogCat, I see this error:
Uncaught Error: NOT_SUPPORTED_ERR: DOM Exception 9 at file:///android_asset/www/scripts/readImages.js: 4
Any ideas?
finally I found out the problem.
I changed the below code:
window.readImageEvent= document.createEvent("readImageEvent");
to:
window.readImageEvent= document.createEvent("Event");
Because "readImageEvent" is not a proper event type. This link could be so useful
about this issue.
According to developer.mozilla.org
The createEvent method is deprecated.
I guess, you can try something like this:
var readImageEvent = new CustomEvent(
"onReadImage",
{
detail: {
images: data
},
bubbles: true,
cancelable: true
}
);
document.dispatchEvent(readImageEvent);
More information about usage, compatibility, etc can be found HERE

I'm trying to figure out if BokehJS can meet my plotting needs for a minor dev project. When I try to copy the last example found on https://docs.bokeh.org/en/latest/docs/user_guide/bokehjs.html it fails with this backtrace in Chrome:
Uncaught TypeError: Cannot read property 'classList' of null
at c (bokeh-1.3.4.min.js:31)
at Object.n.add_document_standalone (bokeh-1.3.4.min.js:31)
at Object.t.show (bokeh-api-1.3.4.min.js:31)
at bokeh.html:58
The example is copied verbatim into a file, bokeh.html, and opened directly in the browser. bokeh.html:58 is the line
Bokeh.Plotting.show(plot);
The example is supposed to be a complete standalone html file so I must be missing something obvious here. My copy of the example can be found here https://pastebin.com/VizzJbH4
Any hints are greatly appreciated.
Move script tag with code at the end instead of head tag.

Why I am getting this error? I guess some of my HTML nodes are not created why I try to call the doSearch method. It's actually happening only second time I call this function.
I'm using React and calling this function inside componentDidUpdate lifecycle method.
Here is my HTML file where I load my script inside
<!DOCTYPE html>
<html lang = "en">
<head>
<meta charset="utf-8"/>
<script type="text/javascript" src="//csr.inspsearchapi.com/lib/infospace.search.js">
</script>
<link rel="stylesheet" href="./static/style/styles.css" />
</head>
<body>
<div class="container"></div>
<script src = "bundle.js"></script>
</body>
Here is my function:
componentDidUpdate(prevProps) {
const signature = this.props.signature ? this.props.signature.response.data : '';
window.insp.search.doSearch({
query: this.state.searchText,
searchUrlFormat: this.state.searchText,
signature,
page: 1,
containers: {
'top': {id:'topResults'},
'related': {id:'relatedResults'},
},
});
}
I'm pretty new to Jasmine testing, and I'm facing a small problem. I have a function like this:
"redirectPage.js"
function clickThis(){
document.getElementById("link").click();
}
How do I test that this function has been called / triggered in my test?
This is my test currently:
describe('Test redirectPage', function() {
beforeEach(function() {
loadFixtures("redirectPageFixture.html");
});
it(" checks if the clickThis() method is triggered", function(){
var spyEvent = spyOnEvent("#link", "click");
("#link").trigger("click");
expect(spyEvent).toHaveBeenTriggered();
});
});
But doing this, gives me this error:
TypeError: "#link".click is not a function
How do I fix this test?
Any help is greatly appreciated!
UPDATE:
This is my fixture:
<html>
<head>
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap-theme.min.css">
<script src="http://code.jquery.com/jquery.min.js" defer>
<link rel="stylesheet" href="css/navbar.css">
<link rel="stylesheet" href="css/searchControl.css">
<script type="text/javascript" src="src/main/resources/assets/js/redirectPage.js" defer>
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
</head>
<body onload="setTimeout('clickThis();',3000);>
<p><a id=link href = "www.google.com">click here</a></p>
</body>
</html>
I finally figured out what I was doing wrong. I was creating the spy on my object, but wasn't actually calling the function that i needed. If any one is interested, this is my test case now:
it(" checks if the clickThis() method is triggered", function(){
var spyEvent = spyOnEvent("#link", "click");
clickThis();
expect(spyEvent).toHaveBeenTriggered();
});
Thank you everyone for your inputs! :)
I would like to change the contents of a div, using javascript and innerHTML.
I cannot get it to work. I just added the code for changing the div, before that the code was working fine. I double checked the syntax.
I'm using webshims, openlayers and jquery/javascript
In the in the console I see
Uncaught TypeError: Cannot set property 'innerHTML' of null
imagegaledit - myFile.php :768
so.onmessage - myFile.php :324
768 is that line
document.getElementById("imgedtitle").innerHTML=mnmi[0];
and 324 is this
imagegaledit(0);
Little help?
Thanks
edit
websockets work and responce fine
Here is the code (concise and simplified)
<!doctype html>
<header>
<meta charset="utf-8">
<meta http-equiv="content-type" content="text/html">
<script src="jquery-1.8.2.min.js"></script>
<script src="js-webshim/minified/extras/modernizr-custom.js"></script>
<script src="js-webshim/minified/polyfiller.js"></script>
<script>
$.webshims.polyfill();
</script>
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<!--open layers api library-->
<script type='text/javascript' src='OpenLayers.js'></script>
<script type='text/javascript'>
//openlayers vars and stuff here...
function init(){
//when a point on map clicked...
function selected_feature(event){

var so = new WebSocket("ws://localhost:8000");
so.onerror=function (evt)
{response.textContent = evt;}
so.onopen = function(){
response.textContent = "opened";
so.send(JSON.stringify({command:'map',fmid:jas}));
}
so.onmessage = function (evt) {
var received_msg = evt.data;
var packet = JSON.parse(received_msg);
//pass data to var and arrays...
imagegaledit(0);
}
}//closes function selected_feature
}//closes init
function imagegaledit (w){
if (w==0){
document.getElementById("imgedtitle").innerHTML=mnmi[0];
}
}//closes imagegaledit
</script>
<body onload='init();'>

You need a closing script tag:
</script>
<body>
I am using Arcgis Javascript API. API is built on dojo toolkit. So I need to use dojo features in API. I am preparing dojo config file as following.
var pathRegex = new RegExp("/\/[^\/]+$/");
var locationPath = location.pathname.replace(pathRegex, '');
var dojoConfig = {
async: true,
parseOnLoad: false,
baseUrl:"js/",
packages: [
{
name: "application",
location: locationPath + '/js/application'
}]
};
I created a bootstrapper.js like following.
require(["application/main", "dojo/domReady!"], function (application) {
console.log("bootstrapper is running");
application.Run();
})
And index.html file is like this.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Arcgis Javacsript API Samples</title>
<link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.5/js/dojo/dijit/themes/claro/claro.css">
<link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.5/js/esri/css/esri.css">
</head>
<body class="claro">
<div id="map"></div>
<script src="//js.arcgis.com/3.6/"></script>
<script src="js/application/djConfig.js"></script>
<script src="js/application/bootstrapper.js"></script>
</body>
</html>
My application is hosted on IIS and has addres like this htp://domain/Demo/Sample1/index.html
when I run application, this code giving error like following.
"NetworkError: 404 Not Found - http://js.arcgis.com/3.6/js/dojo/application/main.js"
If I set bootstrapper.js file as following, problem is solwing.
require(["js/application/main.js", "dojo/domReady!"], function (application) {
console.log("bootstrapper is running");
application.Run();
})
Try to change your script order in index.html file. Your config settings should load before CDN.
<div id="map"></div>
<script src="js/application/djConfig.js"></script>
<script src="//js.arcgis.com/3.6/"></script>
<script src="js/application/bootstrapper.js"></script>
</body>
