JQuery.validate - one rule on blur only; the rest should be normal?

Question

I\'ve worked on a fiddle to show the simple validation that I\'m trying to do for my user ID field:

1. Make it required (validate as aggressively as possible)

Answer 1

I encountered the same problem, and use this way works, not use the remote method:

$.validator.addMethod("userIdCheck", function(value, element, params) {
    if (event.type == "blur" || event.type == "focusout") {
        var result;
        $.ajax({url: "path", async: false,
                success: function(data){
                  result = data;
              }})
        return result;
    } else {
        return true;
    }       
}, "The user ID is already in use");

But this don't work on firefox, event undefined. So I modefied the source code(anyone has another way?):

function delegate( event ) {
    var validator = $.data( this[ 0 ].form, "validator" ),
        eventType = "on" + event.type.replace( /^validate/, "" ),
        settings = validator.settings;
        // add event to validator
        validator.event = event;
        if ( settings[ eventType ] && !this.is( settings.ignore ) ) {
            settings[ eventType ].call( validator, this[ 0 ], event );
        }
    }

then we can use in this way:

$.validator.addMethod("userIdCheck", function(value, element, params) {
    var eventType = this.event.type;
    if (eventType == "blur" || eventType == "focusout") {
        var result;
        $.ajax({url: "path", async: false,
                success: function(data){
                  result = data;
              }})
        return result;
    } else {
        return true;
    }
}, "The user ID is already in use");

Not prefect enough, but this is the only way I find to solve this problem.
