jquery validation plugin rules with condition?

问题

I am using Jquery validation plugin , I have a big form with "Save","Submit" buttons. I have two sets of rules for two buttons.

whenever user clicks save button only valid rulesOne set of rules (mandatory fields email, password).
whenever user clicks save button only valid rulesTwo set of rules (all required fields).

Any one suggest please, how to develop like this ?

Set1 rules:

var rulesOne = { email : "required" .......}

Set2 rules:

var rulesTwo = {city : "required" ..........}

$("#form1").validate({
ignore : '*:not([name]),:hidden',
rules : rules});

If save button

if(this.id == "personal_save"){
  setOne rules test ?
else
// submit button (check all validations)
{
  setTwo rules test ?
}

Thanks Prasad

You cannot dynamically turn validation on/off for any/all parts of a form with this plugin.

However, you can use the .rules() method to dynamically add, remove, or over-ride your rules at any time, giving you a similar behavior.

Then you can use the .valid() method to test the form.

Put them each inside dedicated click event handlers.

$(document).ready(function() {

    // initialize the plugin
    $("#form1").validate({
        ignore : '*:not([name]),:hidden'
        // no rules; rules are set dynamically below
    });

    // Save Button
    $('#save_button').on('click', function() {

        // dynamically set the rules
        $('input[name="email"]').rules('add', {
            required: true,
            ....
        });

        // remove all rules from the other fields
        $('input[name="city"]').rules('remove');

        // force a test of the form
        $("#form1").valid();

    });

    // Submit Button
    $('#submit_button').on('click', function() {

        // dynamically set the rules
        $('input[name="city"]').rules('add', {
            required: true,
            ....
        });

        // remove all rules from the other fields
        $('input[name="email"]').rules('remove');

        // force a test of the form
        $("#form1").valid();

    });

});

If you have many fields, you can make this easier by setting appropriate classes on them like .ruleset1 and .ruleset2. Then you can target them as a group with the .rules() method. Just remember that you'll need to enclose them inside a jQuery .each() if the selector targets more than one element...

$('.ruleset1').each(function() {  // target multiple elements
    $(this).rules('add', {        // apply the rules to each
        required: true,
        ....
    });
});

I faced to the same problem and after a lot of research I came to a solution. It consists in using JQuery.extend to replace the rules property in settings of the validator. I created a jsfiddle based on @Sparky 's one. http://jsfiddle.net/rWsLy/

 $('#save_button').on('click', function () {

var settings = $("#form1").validate().settings;

    // Modify validation settings
    $.extend(settings, {
        rules: {
            field1: {
                required: true,
            },
        },
    });

    // force a test of the form
    $("#form1").valid();

});

I prefer this way because rules are specified in the same way as in validate method. Also I think, previous solution doesn't scale.
