Jquery callback: access to javascript variables other than callback parameters?
-
From withing jquery callback method (such as success or error callback function, for example, in case of jquery ajax get request), how can I access variables other than callback function's parameters. In other words if I have a javascript variable - say, var error_message="blah ..." - how can I access it in an ajax callback - say complete: function(XMLHttpRequest, textStatus). In this particular case, I have access to only two variables - XMLHttpRequest and textStatus. How can I access other javascript variables - say a string variable defined elsewhere?

Answer:
I seem to have access to everything from the callback, even variables defined elsewhere. Make sure the variables you wanna access are within the scope of the callback, not within some other function.

What Khalid said is exactly right. Ensure that you're attempting to call a string or variable described within your function, and script. You cannot call or define variables from other functions / scripts, without writing a script to do just such that. XMLHttpRequest does this for you, but not in the scope or capacity that you desire.
