prototype 原型方法
原标题:Overriding a prototype.js method

I m 试图推翻原样的成像方法。 共同提交文件,为残疾群体增加一个习俗类别。

我补充说:

Form.Element.disable = function(element) {
element = $(element);
element.blur();
element.disabled = true;
element.addClassName("disabled");
return element;}

在装满原型后,该作品如果被直接点名

Form.Element.disable("myInputBox");

但是,如果我打电话,则使用原原型JS方法。

$("myInputBox").disable();

我知道这一点与我界定的“范围”有关,但我不知道如何改变范围,以取代原普罗托类JS版本。

在什么地方我错了?

最佳回答
Form.Element.addMethods({
    disable: function(element) {
        // stuff here
    }
});

http://api.prototypejs.org/dom/Element/addMethods/“rel=“nofollow noreferer”>。

Element.addMethods(["input", "textarea", "select"], {
    disable: function(element) {
        // stuff here
    }
});
问题回答
Form.Element.prototype.disable = function(element) { ... }
