采用重新界定母体方法扩大吉克里的植被
原标题:Extending widgets in Jquery UI with redefining parent methods

I try to extend UI dialog according to documentation (UI version 1.8.16):

(function($) {
    $.widget( ui.mydialog , $.extend(true, $.ui.dialog.prototype, {
        _create: function() {
            return $.Widget.prototype._create.apply(this, arguments);
        }
    }));
})(jQuery);

$(function() {
    $( div#dialog ).mydialog();
});

《刑法》的实施造成《联邦法典》的错误:“这并不明确”。

如果试图凌驾于_init()方法之上,则不存在错误,但母体方法没有影响。

I m confused.. Which way is legal to extending for e.g. put some custom initialize code?

问题回答

如果你想增加植被的功能,不希望取代现有功能,那么,在你们的法典称之为母体方法之后,你会这样做。 为了做到这一点,而不是威廉·尼乌所建议的那样,你只能这样做:

_create: function()
{
    // Custom code here

    // Call the _create method of the widget
    this._super();
}

这适用于所有现有方法(例如_setOption_trigger等)
