I have added jQuery Library 2.1 as javascriptResource in the project. As shown in the picture.
In the index.html, the autocomplete for ready works but, ready function is not called.
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script type="text/javascript" src="main.js"></script>
<script type="text/javascript">
$(document).ready(function(){
alert("Hello");
});
</script>
</head>
<body>
What could I be missing?
Having it available under JavaScript Resources makes it known to the tools, and available for Content Assist at edit-time. It doesn't change the behavior at runtime in the browser--something still has to reference the jQuery file from your web page, like a script tag.
Try to include the jquery script. Example:
<head>
<script src="jquery-1.11.2.min.js"></script>
</head>

Hope it helps.

How do you properly link a JavaScript file to a HTML document?
Secondly, how do you use jQuery within a JavaScript file?
First you need to download JQuery library from http://jquery.com/ then
load the jquery library the following way within your html head tags
then you can test whether the jquery is working by coding your jquery code after the jquery loading script
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--LINK JQUERY-->
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<!--PERSONAL SCRIPT JavaScript-->
<script type="text/javascript">
$(function(){
alert("My First Jquery Test");
});
</script>
</head>
<body><!-- Your web--></body>
</html>
If you want to use your jquery scripts file seperately you must define the external .js file this way after the jquery library loading.
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<script src="js/YourExternalJQueryScripts.js"></script>
Test in real time
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--LINK JQUERY-->
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<!--PERSONAL SCRIPT JavaScript-->
<script type="text/javascript">
$(function(){
alert("My First Jquery Test");
});
</script>
</head>
<body><!-- Your web--></body>
</html>
This is how you link a JS file in HTML
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script> - tag is used to define a client-side script, such as a JavaScript.
type - specify the type of the script
src - script file name and path
To include an external Javascript file you use the <script> tag. The src attribute points to the location of your Javascript file within your web project.
<script src="some.js" type="text/javascript"></script>
JQuery is simply a Javascript file, so if you download a copy of the file you can include it within your page using a script tag. You can also include Jquery from a content distribution network such as the one hosted by Google.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
You can add script tags in your HTML document, ideally inside the which points to your javascript files. Order of the script tags are important. Load the jQuery before your script files if you want to use jQuery from your script.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="relative/path/to/your/javascript.js"></script>
Then in your javascript file you can refer to jQuery either using $ sign or jQuery.
Example:
jQuery.each(arr, function(i) { console.log(i); });
Below you have some VALID html5 example document. The type attribute in script tag is not mandatory in HTML5.
You use jquery by $ charater. Put libraries (like jquery) in <head> tag - but your script put allways at the bottom of document (<body> tag) - due this you will be sure that all libraries and html document will be loaded when your script execution starts. You can also use src attribute in bottom script tag to include you script file instead of putting direct js code like above.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Example</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
</head>
<body>
<div>Im the content</div>
<script>
alert( $('div').text() ); // show message with div content
</script>
</body>
</html>
this is demo code but it will help

I have written a basic Hello World application using jQuery in an HTML page in eclipse.
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
<script type="text/javascript" src="js/jquery-3.3.1.min.js" ></script>
<script type="text/javascript" >
window.onload = function (){
alert("Window loaded");
}
$(document).ready(function(){
alert("DOM loaded");
})
</script>
</head>
<body>
<p>Hello </p>
</body>
</html>`
I have used JRE 8 in eclipse. Upon running it on Chrome, "Window loaded" alert box displays first and then "DOM loaded". Ideally it should be opposite. DOM should load first.
DOM loads first if refernece jQuery library from google APIs.
Could anybody help me on this? The question is not about the comparison between the two.
I'm working on a project, and I didn't understand why a call to external script doesn't work.
Then I just did a extremely simple page html which includes a script alert, as you can see below... Can you tell me what's the problem ? I believe the problem is not the code, but what else can it be?
My browser is a recent Chrome, and my OS is Ubuntu.
My HTML file is index.html :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>MyPage</title>
</head>
<body>
<p>Blablabla</p>
<script type="text/javascript" src="/script.js"></script>
</body>
</html>
The Javascript file is script.js in the same folder:
<script type="text/javascript">
alert('Hey');
</script>
Paths starting with / are absolute paths. If the script and the HTML page are in the same directory, the script's path is simply "script.js":
<script type="text/javascript" src="script.js"></script>
<!-- Here --------------------------^ -->
If the file is in the same folder remove the "/" from script.js
<script type="text/javascript" src="script.js"></script>
Also if the js file has the script tags remove them.
If you want the alert when the doc is ready, consider doing something like:
document.addEventListener("DOMContentLoaded", function(event) {
alert('Hey')
});
I think that the script in the file dosen't need this script tag
<script type="text/javascript">
alert('Hey');
</script>
you can make like this
alert('hey');
just that try out and check if the file path in html to the js file is the right one.
Hi you don't need the script tags in the file:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>MyPage</title>
</head>
<body>
<p>Blablabla</p>
<script type="text/javascript" src="/script.js"></script>
</body>
</html>
The Javascript file is script.js in the same folder:
alert('Hey');
I have solve this problem by using Visual Studio. Just open the html file in VS and then run this file from here. It will connect your js file to html.
how to rename $ and jQuery ?
I have created widget and which is used in 3rd party website.
As i am getting conflict with jQuery with 3rd party website.
And I don't aware about which version of jquery 3rd party is using so i am stuck at this point.
so now if it is possible to rename ,then let me know how to do it in jquery.js library.
Otherwise i have to rewrite whole my script (about 3000+ lines) in native java script. and this is not possible because my script using third party js like fullcalendar, colorbox, validationengine etc. which fully dependent on jquery.
<html>
<head>
</head>
<body>
3rd party website
<script src="jquery-1.5.js"></script>
// My widget code : Start
<script src="http://my-domain.com/my-widget.js"></script>
<div id="my-result"></div>
// My widget code : End
</body>
</html>
EDIT 1
<html>
<head>
<title>title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<script src="http://code.jquery.com/jquery.js"></script>
<script type="text/javascript" src="script.js"></script>
<div id="my-result"></div>
<script src="js/jsapi" type="text/javascript"></script>
<script type="text/javascript">
google.load('jquery', '1.5');
</script>
<!--<script src="http://code.jquery.com/jquery-migrate-1.2.1.js" type="text/javascript"></script>-->
</body>
</html>
it's not recommended to change code in the jquery file itself, just use no conflict:
<script src="jquery.js"></script>
<script>
var $j = jQuery.noConflict( true );
// $j will point to your jquery version
$j('#somediv').show();
</script>
after seeing the last edit, you can surround your my-widget.js code with closure that way your code will know $ as your version as jquery:
(function( $ ) {
// all my-widget.js code
})($j);
I write some html and js to a iframe,not working in IE7/8/9,the error message is:$ is not defined?

</script>
</head>
<body>
<iframe id="code_result" frameborder="0" class="frame_result" name="code_result"></iframe>
</body>
</html>
who can tell me why?thanks
update
this error only show in IE78/9,it work well in Chrome and FireFox
It's not the code loading the I frame content. It's ie's loading order. Simply wrap your I frame script in a window onload function so it allows jquery to load first. Tested and working in ie.
Add:
$(document).ready({
alert('123');
});
You will need it load jquery in the I frame before running code. JQuery hasn't loaded yet.
