好的，所以我要做的是在验证后将输入的标签类更改为绿色。除非你推荐，否则我没有看到任何错误类别的需要。
问题在于，一旦验证该类自动为绿色。我用不同的ID和类来尝试这个。
这里是URL所以你可以看到我想要的东西。
$(document).ready(function() {
jQuery.validator.setDefaults({
success: function(label) {
$("#fnameLabel").css("color", "#18bc9c");
},
submitHandler: function(form) {alert("valid form");}
});
$("#contactForm").validate({
onkeyup: function(element) {
$(element).valid();
},
rules: {
fname: {
required: true,
minlength: 2,
maxlength: 20,
},
lname: {
required: true,
minlength: 2,
maxlength: 20
},
email: {
required: true,
email: true
},
ts: {
required: true
},
message: {
required: true,
minlength: 20,
maxlength: 300
}
},
messages: {
fname: {
required: "Please enter a name.",
minlength: $.format("At least {0} characters required."),
maxlength: $.format("Maximum {0} characters allowed.")
},
lname: {
required: "Please enter a name",
minlength: $.format("At least {0} characters required."),
