jQuery Validation - Highlighting Radio Labels

I'm trying to use jQuery validation to highlight the labels for my radio buttons only, and not the labels for my other inputs. I have a label for my radio button set called 'type'. I can't seem to get it to work!

$(document).ready(function(){
    $("#healthForm").validate({

 highlight: function(element, errorClass) {
     $(element).addClass(errorClass)
     $(element.form).find("label[for='type']")
                    .addClass("rad开发者_StackOverflow社区ioerror");
  },
  unhighlight: function(element, errorClass) {
     $(element).removeClass(errorClass)
     $(element.form).find("label[for='type']")
                    .removeClass("radioerror");
  },
    errorPlacement: function(error, element) {
        }
    });
  });

I'm not really familiar with jQuery's validation plugin, but this one doesn't seem right:

$(element.form).find("label[for='type']")

Firstly, I think $(element.form) should be $(element).closest('form')? I could be wrong :P

Secondly, .find("label[for='type']") has got nothing to do with the "element" as any other elements in the same form will fetch the same label.

If the label is the sibling of the radio button, you might want to use sibling() directly.

I changed your code to the following and then it works!

$(document).ready(function() {
    $("#healthForm").validate({
        highlight: function(element, errorClass) {

            if(element.type == 'radio') {
                $(element.form).find('[name="' + element.name + '"]').each(function(){
                    var $this = $(this);
                    $this.closest('label[for="' + $this.attr('id') + '"]').addClass(errorClass);
                });
            }

        },
        unhighlight: function(element, errorClass) {

            if(element.type == 'radio') {
                $(element.form).find('[name="' + element.name + '"]').each(function(){
                    var $this = $(this);
                    $this.closest('label[for="' + $this.attr('id') + '"]').removeClass(errorClass);
                });
            }

        },
        errorPlacement: function(error, element) {
        }
    });
});
