I am trying to do form validation using jquery validation. I am trying to give my own error messages. But this code is not running.

When I tried

 <input type="text" id="cemail" class="required"></input>

the code is working fine, but with this , I am not able to give custom error messages. Please let me know if I am doing something wrong in upper code.

EDIT: I have another concern as well , if validation fails for any control, I want to change the background color of that control. And I also want to remove the default error message.

There are 2 issues, mainly you need to use the name attribute (not the id attribute), so name and email, not cname and cemail for your rules. Also, the {} around the email error message needs removing. Overall you want to look like this:

$("#frm").validate({
    rules: {
        name: { required: true },
        email: { required: true, email: true }
    },
    messages: {
        name: "Please enter your name",
        email: "Email is not validated"
    }
});

You can give it a try here.

cemail and cname should be added to input elements as class, not ID.

example:

<input class="cemail" name="email" size="25"  />

format should be like this...

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

        rules: {
            cname: {
                required: true
            },
            cemail: {
                required: true,
                email: true
            }
        },
        messages: {
            cname: { 
                required: "Please enter your name"
            },
            cemail: {
                email: "Email is not validated"
            }
        }
    });
});

cname and cemail are the values of name attribute of the input.
