问题
I have the following button:
<input type="submit" id="btnLogin" onclick="return ValidateLogin();" value="Enter">
How can i find the definition of the ValidateLogin() function with firebug?
回答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.
回答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.

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.

go to HTML label. Here you can view also the contents of the Javascript file included in the page.
I hope it's helpful.
