Debug JavaScript in Eclipse
In 2015, there are at least six choices for JavaScript debugging in Eclipse:
- New since Eclipse 3.7: JavaScript Development Tools debugging support. The incubation part lists CrossFire support. That means, one can use Firefox + Firebug as page viewer without any Java code changes.
- New since October 2012: VJET JavaScript IDE
- Ajax Tools Framework
- Aptana provides JavaScript debugging capabilities.
- The commercial MyEclipse IDE also has JavaScript debugging support
- From the same stable as MyEclipse, the Webclipse plug-in has the same JavaScript debugging technology.
Adding to the above, here are a couple of videos which focus on "debugging JavaScript using eclipse"
- Debugging JavaScript using Eclipse and Chrome Tools
- Debugging JavaScript using Eclipse and CrossFire (with FB)
Outdated
- The Google Chrome Developer Tools for Java allow debugging using Chrome.
I don't believe Eclipse has a JavaScript debugger - those breakpoints are for Java code (I'm guessing you are editing a JSP file?)
Use Firebug to debug Javascript code, it's an excellent add-on that all web developers should have in their toolbox.
