In an HTML file, I included jQuery via
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" ></script>
I downloaded the library via the context menu and now see it in the project folder under External Libraries. Yet, it seems jQuery is not recognized.
<script type="text/javascript">
$(document).ready(function() {
..
});
</script>
The $ is underlined and code hinting asks me to create a function or method called $. The code itself works though.
What am I supposed to do to make PhpStorm recognize the external JavaScript library?
As LazyOne pointed out in his comment I had to look up settings, and there I realized I had to download the library again, and made it global.

I need to load an external application that contains the complete jQuery 3.2.1 library inside of it. Because it is an externally hosted app, it's not realistic to modify the code. However, when I add the script to my page, I end up with lots of errors due to conflicts with other scripts already loaded. As an experiment, I've tried downloading the app and wrapping the contents in an anonymous function, thinking that this would keep the new version of jQuery scoped locally within the app but it didn't make any difference.
Is there a simple way to include this app without modfying it's contents or relying on jQuery.noConflict() which would require many changes to my existing code?
you can use jQuery.noConflict() in your code with limited changes by simply wrapping all of your code that uses jQuery in an IIFE and passing in the instance of jQuery you are using
try something like
<script src="path-to-your-jquery.js"></script>
<script>var $jQ = jQuery.noConflict();</script>
<script>/* your plugins */</script>
<script>
(function($){
/* your code using `$` works fine here*/
})($jQ);
</script>
<script> /* other app code */</script>
I am very new to web development and Javascript in general and I hae done some Jquery coding by adding my code in my HTMl code all the time. Now, I just moved the same code to my .Js file and my console shows me following error:
$ is not defined [Break On This Error] $(document).ready(function () {
It just says JQuery is not defined. It means that I can not refer to Jquery or any other Javascript files in my Js file?
Or there is something that I am missing here?
Just include jQuery before your script is called
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
For other jQuery stuff available in CDN, see this:
http://docs.jquery.com/Downloading_jQuery#CDN_Hosted_jQuery
Update: This is as close to "using" as you can get, in my mind. It's not required to download the jQuery library to your system or host it on your server.
in your html did you move the whole jquery file into your .js file? you shoudl have it as something like:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"type="text/javascript"></script>
// Now load your .js file
<script type="text/javascript" src="your .js file"></script>
Also if you downloaded jquery forget about it, the top link means you're loading jquery from google so you'll always have the latest version, I really cant be much more help unless you upload your code, sorry.
I have a few JSP pages, that include some JavaScript(jquery, jquery mobile and some javascript functions that I wrote).
When loading the pages and try to run my functions, I get in Firebug an error, that the function was not found. I have looked into the page source, and the function is there.
All the other jquery mobile functions work.
The only way to make my script work is to make a forced refresh(ctrl+f5).
Why is this happening? How can I fix it?
EDIT
It seems that a simple refresh would also work.
Here is the source code of the page:
http://pastebin.com/6sJnfPDQ
I have retagged your question to remove "Java" and "JSP", as this is irrelevant (server vs browser).
Once your JSP is rendered in the browser, please do look in the page source and see what happened to your tags.
make sure all of your js files are being loaded properly.
also make sure that your js files are being loaded in the proper order.
make sure that, where necessary, you're wrapping your JS in a document ready function of some type
also, I recommend that you add the type attribute to your script tags:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script>
I have website A: http://dl.dropbox.com/u/3264697/calc/v2/index.html
It is working as intended, 100%.
I have website B: http://pe2kasb.net63.net/
It is not working as intended. Website B is a file for file mirror of A.
I assume then, this is something wrong with the host. Looking at the Javascript console, the error appears to be related to the host:

Need I contact them, or is there something I can do...? I'm new to JQuery, and I believe that's what is the root of the issue but... i'm not sure.
You are trying to load jQuery from ../v2/media/js/jquery.js but there is no such file in the second website.
I recommend that instead of hosting JQuery yourself, you use a hosted version:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js" type="text/javascript">
</script>
This post explains the reasons.
You have invalid jQuery path at http://pe2kasb.net63.net/
Replace
<script type="text/javascript" src="../v2/media/js/jquery.js"></script>
with
<script type="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
Also you have dataTable.js missing.
You are loading JQuery from ../v2/media/js/jquery.js which does not seem to exist...
To solve the issue and improve the speed of the website
do not store JQuery on the server, rather load it from a 3rd party (Google works well)
use JQuery minified version
To load JQuery from Google you can just use:
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("jquery", "1");
</script>
More information here
EDIT: note that the above automatically loads the minified version of JQuery. If, for whatever reason (?) you wanted to load the uncompressed version you could use
google.load("jquery", "1", {uncompressed:true});
Look what http://pe2kasb.net63.net/v2/media/js/jquery.js refers to.
The file does not exist.
Upload it or include it from another location.
Make sure that jQuery is correctly linked, currently jQuery is supposed to be at "../v2/media/js/jquery.js" on "http://pe2kasb.net63.net/", which means go back one folder then enter "/v2/media/js/jquery.js".
i need jquery to work on a browser locally. how do i know if it is installed and how do i install it ?
my question is specific to being able to run this code:
onmouseover="evt.target.setAttribute('opacity', '0.5'); $('#someDiv').show();"
onmouseout="evt.target.setAttribute('opacity', '1'); $('#someDiv').hide();"
You can test if jQuery is loaded by opening your javascript console (in Chrome: Settings > More tools > Javascript console).
Where the little blue arrow appears type:
if(jQuery) alert('jQuery is loaded');
Press enter.
jQuery isn't installed like a program, it's a file that needs to be included in your source code somehow, the most common practice is to include by adding <script type='text/javascript' language='javascript' src='local/path/to/jquery.js'></script> in the <head> section of your page.
If you are going to include jQuery locally, as per Robert's suggestion, you will first have to download it from here: http://code.jquery.com/jquery-1.4.2.min.js
put this right above your closing body tag:
<script src="//ajax.googleapis.com/ajax/libs/jquery/[jquery version here]/jquery.min.js"
language="javascript" type="text/javascript"></script>
jquery isn't "installed" into a browser. it's a js library referenced from the web page you are viewing.
EDIT: This works if you have internet access. If not, you will have to download that file to your local system and reference the local path.
