使用firebug在JavaScript中查找内存泄漏？

Question

是否有任何Firefox附加组件可用于查找部分JavaScript导致内存泄漏？

Answer 1

I've got nothing for firefox, but the webkit inspector in Chrome has a profiler built in that is great for that kind of thing.

As an added bonus it also shows you all browser events such as repaints, so you can engineer your code to have the least impact on the browser.

Use Drip.exe / IEleak , I used it a lot to search for memory leaks!

Other hits:

• jQuery itself prevents a lot of memory leaks!
• Test your code with http://jslint.com
• There is a tool by Microsoft itself, but I don't know it is up to date: http://blogs.msdn.com/b/askie/archive/2008/12/31/javascript-memory-leak-detector-for-internet-explorer.aspx
• There is also integration with Visual Studio: http://berniesumption.com/software/how-to-debug-javascript-in-internet-explorer/
• There is a good article about mem leaks http://www.ibm.com/developerworks/web/library/wa-memleak/

The best memory profiler I've found is for IE (supports even IE6 ;-). Give it a go - you will be surprised how good it is:
