Method 'isValidEmail', why $(this) is not valid?

Hi, I know what is the correct answer, but I would like to know why the following code is not correct:

function isValidEmail(email) {
    return $(this).indexOf("@") != -1;
};

I thought $(this) would be related to the email.

Thanks a lot!

Hi, no.

$(this) relates to the element that the function is relating to. So if you had a click function that was something like 

$('#activator').click(function(){
    $(this).animate({...});
});

When you click on #activator, the animation would act upon #activator, QED $(this).
