Find Js Function With Firebug

I have the following button: How can i find the definition of the ValidateLogin() functio

Solution 1:

Type the following into the Firebug Console, then click the function() in the output window

var s = ValidateLogin.prototype.constructor;
console.log(s); // will output the actual function definition 

I have included some screenshots to help.

Solution 2:

To get the function definition only this would be a shortcut in the firebug console:

console.log(ValidateLogin.toString());

The defintion of the function will be printed to the console directly.

Solution 3:

There is a search field on the top right of Firebug. When you are on the Script panel and focus the search field, you'll get a small dialog which a check box "Multiple Files" (or something similar - I don't have the English version). Check it and copy the name of the Function you are looking for into it.

Solution 4:

go to HTML label. Here you can view also the contents of the Javascript file included in the page.

I hope it's helpful.
