jQuery验证插件分组和asp.net

Question

I am using jQuery Validation plugin.

I want to display only one error message for Date of birth, year and month. I am using groups for that. I am getting a reference error for TelephoneNumber, I think it is not recognizing the name attritbute like I have mentioned below. Please see the code below and advise if I am doing anything wrong.

 rulesObject[$("select[id$='ddlDOBDay']").attr('name')] = {
      required: true,
      valueNotEquals: "DFT"
  };
  rulesObject[$("select[id$='ddlDOBMonth']").attr('name')] = {
      required: true,
      valueNotEquals: "DFT"
  };
  rulesObject[$("select[id$='ddlDOBYear']").attr('name')] = {
      required: true,
      valueNotEquals: "DFT"
  };

          groups: {           
                TelephoneNumber: "$("select[id$='ddlTel2']").attr('name'), $("input[id$='txtTelephone2']").attr('name')"
           },
          errorPlacement: function(error, element) {                      
                if (element.attr("name") == $("select[id$='ddlTel2']").attr('name') || element.attr("name") == $("input[id$='txtTelephone2']").attr('name')) 
                error.insertAfter($("input[id$='txtTelephone2']"));
                else 
                error.insertAfter(element);
          },

The line

TelephoneNumber: "$("select[id$='ddlTel2']").attr('name'), $("input[id$='txtTelephone2']").attr('name')"

is not valid JavaScript. You can see where SO's syntax highlighting breaks, this probably stops JavaScript from being executed at this point resulting in the error (just saw your comment).

Try

TelephoneNumber: $("select[id$='ddlTel2']").attr('name') + ', ' + ("input[id$='txtTelephone2']").attr('name')

This will produce the string that I think you want.
