I've read several DATED information on how to enable jQuery (specially auto completion) support for Eclipse. Either using Aptana or other plugins.
I've tried Aptana 3 version plugin, but I get nothing but problems.
Can someone please explain on how to achieve this?
Maybe nowadays there are better options from Aptana.
Tried with Eclipse Indigo and Helios, and still Aptana Web tools pkg. does not work.
I got the jQuery code completion in Juno. Just follow the following steps:
1) Install the JSDT jQuery Integration plugin
2) Go to Project Explorer--> JavaScript Resources
3) Right click on it and go to properties.
4) Select "Add JavaScript library"
5) Select "jQuery Library"
6) You will get code completion as follows
Enjoy.
Much simpler thanks to logic8 comment is to add it from

and enter http://svn.codespot.com/a/eclipselabs.org/jsdt-jquery/updatesite
Tada!!
I have used https://marketplace.eclipse.org/content/angularjs-eclipse Once you install this you can right click on your project , Configure to Angularjs project ,
And that's it.
There is just something I have not seen anyone say.
If you already have a ready project, but when you created it did not using a javascript project, then you must convert your existing project.
Keep calm, because this conversion will not harm your existing project.
Right click on your project>Configure>Convert to javascript project
Ready! Now you can follow the step by step our friend up here did.
I believe this can really help beginners like me.
