Ok, so say you have a page, and when it loads, it runs everything in  
application.js.

Here, there is some code in between:  
Event.observe(window, ‘load’, function(){

// Code goes here.

})

Does anyone know, how you could get the same code to run, after  
responding to certain ajax calls?

For example, someone clicks on one of the link\_to\_remote links on the  
page, a call is made, and the js code in application.js is run again.

Is this possible?

Well you’ve got a bunch of callbacks with link\_to\_remote  
(:complete, ;success, :failure etc…) Will those do?

Thank you.
