I have followed the steps described here for adding the autocomplete functionality to the eclipse.
In this after installing JSDT plugin, I have to create a project, then add the plugin as a JS resource. I have found two weird things:
- I can get autocomplete even I have included no jQuery library in my html

- I cannot get the autocomplete for HTML file that I created explicitly say in notepad and opened in eclipse. For example in screenshot above in tempq.html I can get the autocomplete but in angularjsexp.html which is open in the another tab and which is not the part of any project I cannot get the autocomplete for jQuery when I enter
$().
Also how can I get similar autocomplete for angularjs in eclipse. I read somewhere using JSDT only I can get the autocomplete functionality for angularjs too. Is it possible?
JSDT is JavaScript Development Tools, it mainly focuses on providing support for js development and by default adds JQuery auto completion support.
For html auto completion install HTML Editor plugin for eclipse from marketplace. To do a quick install use "Eclipse Marketplace" option under Help menu in eclipse, Once this is done html and css code completion works.
For AngularJs code completion support couldn't find any do share if you find a solution for it.
