标签: jquery forms validation

我正在使用jQuery验证插件,我正在尝试在消息div区域中显示名字和姓氏。该名称仅短暂出现并消失。我无法弄清楚原因。

此外,当字段为空时,我会收到错误消息,但现在我的下拉列表中的选项在通过验证过程后仍未显示。

//form
 $(document).ready(function() {

var display = function () {

        var fullName = $("#FirstName").val() + ' ' + $("#LastName").val();
        return fullName;

}

    $("#myForm").submit(function(){
    $("#message").empty().append (display());
    $(":input").empty();
}); 

 //validate
$("#myForm").validate ({
rules: {
  FirstName:  {
  required: true,
  FirstName: true 
  },
LastName:  {
  required: true,
  LastName: true 
  },
Email:  {
  required: true,
  Email: true 
  },

errorPlacement: function(error, element) { 
   if ( element.is(":radio") || element.is(":checkbox")) {
      error.appendTo( element.parent()); 
    } else {
      error.insertAfter(element);
    } 

    }

     },


messages: {
  FirstName: "Please enter your first name",
  LastName: "Please enter your last name",
  Email: "Please enter your email address",
  submitHandler : function() {
  display();
   }

}
    }); //end validate  

    //toggle

    $("#toggleDiv").hide();
    $("#toggleField").click(function(){
    $("#toggleDiv").toggle("slow");
    }); 

   }); // end ready
