For example; They are my links, HomePage开发者_如何学C - Users

Thanks for answers.

First of all, your individual Javascript functions should only be running for split seconds. There should be no single long-running function that you need to actually interrupt. If there is, you need to design it so it is interruptable. Like:

function foo() {
    while (/* something */) {
        if (stopFlag) {
            return;
        }

        // do something
    }
}

When you want to interrupt the function, you set the global stopFlag to true and the function will exit soonish. That's rarely a necessary design pattern in the browser though (and only possible to a limited extend in the first place due to the single-threadedness of JS).

The best answer I can give to this vague and broad question of yours: design your Javascript in a way that you don't have this problem in the first place.

$('.element_class').click( function(event){
// your code here
event.preventDefault();
});

or

$('.element_class').click( function(event){
// your code here
return false;
});
