get the value of variable exist inside the ajax

Question

I want to validate email, what's wrong in this. Return false is not working

$.validator.addMethod("email_exist", function(value, element, arg){
    var x = 0;
    $.ajax({
        url: '../signup/validateemail.php',
        type: 'post',
        data: 'email_address='+value,
        cache:false,
        success: function(response) { 
            if(response == 0){
                x++;
            }
        }
    });
    alert(x);
    if(x > 0){
        return false;
    }else{
        alert('yeh');
        return true;
    }
    return true;
 },'');

You do asynk call.So in you case,first execute alert(x),then code in success function. You can do this request synk (async: false) or change code in success

it wont return false as the ajax method is asynchronous, it will not wait for the success event to happen. You can make the ajax synchronous by making

async: false

but it is not a good method. It will freeze the browser as well
