How do I get this function to run after all this other code is done?

I'm creating a register form with jQuery, and I'm trying to add a function to be run upon completion with no errors.开发者_运维问答 What I'm trying to figure out is how to get it run after all the rest is done, so I know what my variable 'hasErrors' is, rather than undefined. Here is my relevant code:

$('form.register .submit').click(validateRegister);

function validateRegister(){
    var hasError = false;

    //This is executed if something goes wrong. Basically I want my success() function to be run if this is never run, so at the end.
    function returnErrors() {
            $processing.hide();
            $this.parent().removeClass('processing');
            $endNote.slideUp();
            hasError = true;
    }

    if (hasErrors == false) {
        success();
    }   
        return false;
    }

Any help with this is extremely appreciated. Thank you!

I think you want to do something like:

function validate() {
  var isValid = false;

  // do some validation here
  // if it passes, set isValid = true

  if (isValid) {
    success();
    return true;
  } else {
    error();
    return false;
  }
}

jQuery also has an add-on for form validation that you might be interested in, but it could be overkill depending on how complex your needs are.
