使用此插件无法动态打开/关闭表单的任何/所有部分的验证.

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

但是，您可以使用 .rules()方法动态添加，删除或覆盖您的随时遵守规则，为您提供类似的行为.

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

然后，您可以使用 .valid()方法来测试表单.

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

将它们分别放入专用的click事件处理程序中.

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();

    });

});

如果您有许多字段，可以通过在它们上设置适当的类(例如.ruleset1和.ruleset2)来简化此过程.然后，您可以使用.rules()方法将它们定位为一个组.只需记住，如果选择器针对多个元素，则需要将它们包含在jQuery .each()中.

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,
        ....
    });
});
