jQuery ajax return value

I have this jQuery script:

$('#headerSubmit').click(function() {
    var source = $('#header').attr('value');
});

that gets the value attribute of the element and stores it in the source variable.

How do I return the source variable to use in the rest of the script?

Thanks.

Answer 1

As you would be setting the source variable after a click, any code that uses that variable should be executed only after such event. Therefore, you should paste your code right after it:

$('#headerSubmit').click(function() {
    var source = $('#header').attr('value');
    // Rest of the code here
});

Otherwise, the variable wouldn’t be initialized before a click.

Edit: Note all other answers incite you to declare the variable on global scope. This is useless unless your code executes after a click since the variable would be null.
