jquery.validate remote验证另一种写法

function checkName() {
    var deferred = $.Deferred();//延迟方法
    var Name = $("#name").val();
    var Names = $("#names").val();
    var Pid = $("#pNodeId").val();
    var nodeId = $("#nodeId").val();
    $.ajax({
        type:"post",
        url:"../Category/verifyName",
        async:false,
        data:{
            Name:$("#name").val(),
            Pid:$("#pNodeId").val(),
            nodeId: $("#nodeId").val()
         },
         dataType: "html",
         success: function(data, type) {
             if(data=="ok"){
                 deferred.resolve();
               }else{
                  deferred.reject();
               }    
          }
    });
    //deferred.state()有3个状态:pending:还未结束,rejected:失败,resolved:成功
    return deferred.state() == "resolved" ? true : false;
}           

jQuery.validator.addMethod("valCheckName", function(value, element) {
    return checkName();
},‘名称已存在‘);

//表单校验
$(‘#form‘).validate({
    submitHandler:function(form){
        if(checkName()){//提交前再次验证是否重名
        　　form.submit();
    　　}
    },
    rules : {
        name : {
                required : true,
                byteRangeLength : [2, 32],
        　　　　 valCheckName:true
        },
        note : {byteRangeLength : [3, 200]}  
    }
});
