how to stop execution with return false in javascript?

Question

i have the fallowing example:

<input type="button" id="create_account" value="Save">

var Misc = {
    validateForm: function () {
        if(x == 1){
            return false;
        }
        // this is a simplified example, but sometimes x != 1 and there is no return
    }
}

$(document).on('click', '#create_account', function() {
    Misc.validateForm();
    alert('continue');
});

the issue i'm having is that i get continue, even though i return false.

what i would like to happen is to run the alert only if Misc.validateForm(); doesn't return anything

any ideas on this issue?

flow doesn't stop just because you return false, it would be like saying, false; alert('continue'), still gonna alert. — Dave Chen

You need to

$(document).on('click', '#create_account', function() {
    if(Misc.validateForm() === false){
        return;
    }
    alert('continue');
});

Right now you are returning false but that does not determine that execution stops. You should use something along the lines of:

if (!Misc.validateForm()) {
    alert('continue');
}

yes, i figure that much (witch is a bit different), the idea was to use Misc.validateForm() to either stop or continue the script. but thanks
