Hello,  
I have started to make an application, and now it’s very big and starts  
to appear problems in javascirpt code.  
I can’t use ie debugger because i have contents of page loaded by ajax  
and they didn’t apear when i look on line 128 as debugger tells me.  
I wan’t to know if it’s a javascript debugger or ruby debugger to get  
the errors.  
thanks

For javascript, use Firefox + Firebug :  
[Firebug](http://getfirebug.com/js.html)

For (visual) Rails debugging, you might give a try at Fyre

For debugging javascript in IE you can use firebug lite :  
[Firebug](http://getfirebug.com/lite.html)

This technique is illustrated in the peepcode #8 :
