$("form[开发者_如何转开发name='registeruser'] input[name='register']").live('click',function(){
        //validateregister($("form[name='registeruser']"));
        var frmvalidator  = new Validator("registeruser");
        frmvalidator.addValidation("name","req");
});

ok problem was that i was using a simple button to submit the form. which is not allowed in this script. I have to change the button to a submit button.

and i you really want to use a simple button instead of submit button, then following code can be used

in your form

<input type="button" value="submit" name="register" />

in your jquery

$("#registeruser input[name='register']").live('click',function(){
 //check if form 'registeruser' is valid or not
        if($("#registeruser").valid())
        {
            alert("ok");
        }
        else
        {
            jQuery.validator.messages.required = "";

            $("#registeruser").validate({
              errorClass: "requiredfields",
              highlight: function(element, errorClass, validClass) {
                 $(element).addClass(errorClass).removeClass(validClass);
              },
              unhighlight: function(element, errorClass, validClass) {
                 $(element).removeClass(errorClass).addClass(validClass);
              },
              errorPlacement: function(error,element) {}

             });    
        }
