Question

I am using jQuery Validate plugin: http://bassistance.de/jquery-plugins/jquery-plugin-validation/

Simple demo:

  <input type="text" name="email" class="required email" />
  <input type="text" name="email_confirm" class="required email" />

How to check if the values ​​in two inputs match with jQuery or with the jQuery validation plugin.

I just tried equaltoand it works:

rules: {
  email: 'required',
  email2: {equalTo: '.email'}

Answer 1

When viewing the demo page http://jquery.bassistance.de/validate/demo/ you can check 2 fields that should be equal using "equalTo":

    $("#signupForm").validate({
    rules: {
                    ...snip... 
        password: {
            required: true,
            minlength: 5
        },
        confirm_password: {
            required: true,
            minlength: 5,
            equalTo: "#password"
        },
                   ...snip...
    },
    messages: {
        ...snip...
        password: {
            required: "Please provide a password",
            minlength: "Your password must be at least 5 characters long"
        },
        confirm_password: {
            required: "Please provide a password",
            minlength: "Your password must be at least 5 characters long",
            equalTo: "Please enter the same password as above"
        },
        ...snip...
    }
});

, . equalTo, , , - :

class="required email equalTo['email']"
