I have a common error function which is called from many places. I want to know from which function this was called. Is there any way to do it?
In any javascript function you can use
arguments.callee.caller
if You want to execute JS in chrome you have to do like this
go to console and type your JS and enter!

you can use eval();

I've looked everywhere and can't find a solution. I'm using the console part of developer tools on chrome if that helps :)
I've tried various configurations such as the example below, and all give me an error
setTimeout(s)5
I'm not sure exactly what you are trying to do, but I think you need to pass a function and the length of timeout into the setTimeout method like this example
setTimeout(function(){ alert("Hello"); }, 3000);

What is the purpose of jQuery clean and cleanData methods?
(2 answers)
Closed 8 years ago.
I have to update some code using jquery and I have the following statements :
$.each($.clean({0:data}, this.ownerDocument), fct);
Where data is html content from server.
I didn't find any documentation about this method.
I just know that Jquery 1.9 remove it
Those methods are not meant to be used outside of jQuery, that's why you are having so much trouble finding documentation on them.

Why can I use a function before it's defined in JavaScript?

I have noticed that when coding in javascript, it doesn't matter if i declare the function before or after i call it. In other languages it will cause an exception, but when running javascript in chrome it works just fine. Is that only in chrome, or is that normal?

JavaScript: immediate function invocation syntax
A similar question has been asked here
there, the author asked about the difference between
(function(){})();
and
function(){}();
the purpose of the first is, among other things, to inform the reader that the function is to be immediately executed. I have also seen this version
(function(){}());
Is this the same as the above two?
This variant function(){}(); will give you syntax error
