Customising event delegates in the jQuery validation plug-in

问题

I am currently setting up the jQuery validation plug-in for use in our project.

By default, there are some events automatically set up for handling. I.e. focus in/out, key up events on all inputs fire validation. I want it to only fire when the submit button is clicked.

This functionality seems to be in-built into the plug-in, which is making it difficult to do this (without modifying the plug-in code, Not What I Want To Do).

I have found the eventDelegate function calls in the plugin code prototype method:

        $(this.currentForm)
            .validateDelegate(":text, :password, :file, select, textarea", "focusin focusout keyup", delegate)
            .validateDelegate(":radio, :checkbox, select, option", "click", delegate);

When I remove these lines from the plug-in I get my result, however I would much rather do something Outside the plug-in to achieve this.

Can anybody please help me? If you need any more details, please let me know. I have searched google with little success.

Thanks

EDIT: I am basically trying to validate the form Only when the submit event is fired. By default, the plug-in validates every time focus is lost in an input control.

Found the answer. It was (hidden?) away as part of the options in the validate method.

See the options onfocusout etc on this page: http://docs.jquery.com/Plugins/Validation/validate#options

which I can set to false.

Here is my code which sets up my validator (hopefully others will find this useful):

$(document).ready(function() {
    $("form").each(function() {
        $(this).validate({
            validateDelegate: function() { },
            onsubmit: true,
            onkeydown: false,
            onkeyup: false,
            onfocusin: false,
            onfocusout: false,

            errorContainer: "#PanelError",
            errorLabelContainer: "#PanelError ul",
            wrapper: "li",
            ignoreTitle: true,
            errorClass: "Error",

            highlight: function(element, errorClass, validClass) {
                $(element).addClass(errorClass).removeClass(validClass);
                $(element.form).find("#" + element.id)
                        .addClass(errorClass);
            },
            unhighlight: function(element, errorClass, validClass) {
                $(element).removeClass(errorClass).addClass(validClass);
                $(element.form).find("#" + element.id)
                        .removeClass(errorClass);
            }
        });
    });
});
