JavaScript code content assistance built in Eclipse WTP does very good job that I found even better than the same functionality in some commercial solutions, however, JQuery’s syntax is not supported (no surprise). That’s why jQueryWTP tool comes to help adding JQuery support to Eclipse WTP (and Eclipse PDT, MyEclipse which are based on WTP too.)

This is not an Eclipse plugin instead a tool to patch the existing plugin and inject JQuery’s syntax support into it. First download the tool from SourceForce; it’s a Java executable JAR so you can double-click to it or run it from command line:

java -jar jqueryWTP0.2forJQuery1.2.6.jar

Now browse to plugin file

org.eclipse.wst.javascript.ui_xxxxxxx.jar

and set output directory to generate the patch. Please backup the original file and set output directory different from source one.

Select “Generate” button to get the patched file then copy over original file. Start Eclipse and open a HTML or script file to see JQuery’s functions listed on code assistance like image below.
