How To Validate Integer Value In Jquery

I need to validate input field, it should be integer(0-100), if max_seat = 5 then min_seat should be less than or equal to max_seats.

You must declare each rule separately. And for an integer, you can use the digits method.

Your HTML is also not valid for this plugin...

<input class="span6 " id="max_seat"  name="default_seats" type="text" />
<input class="span6 " id="min_seats"  name="default_seats" type="text" />

Each field must contain a unique name attribute and you would declare your rules based on that name. (Declare the messages option similarly)

rules: {
    min_seats: { // <- this is the NAME attribute of the field, not ID
        required: true,
        digit: true
    },
    max_seats: { // <- this is the NAME attribute of the field, not ID
        required: true,
        digit: true
    }
}

To compare the two fields, you must use the .addMethod() method and declare your new custom rule the same as above.
