在带我铁路的铁路(3.0x,仍然有原型)中,我看到以下结构:

(function() {
// ...
document.on("click", ...
})();

在匿名职能中总结整个法典究竟取得了什么成就? 这是否是将守则延迟到很少装上或只是文件标的为止的有效途径?

在我的项目中,我目前在<条码>Event.observe(文件,标题:载荷、功能(){......>栏内有许多定式代码。 我不禁要问,如果我对我的守则作出修正,我是否应当采用上述模式。

最佳回答

http://www.yuiblog.com/blog/2007/06/12/module-pattern/“rel=“nofollow”>module patterns。 这样做是有益的,因为直接援引的职能中的变量是当地的,不会污染全球名称空间。

(function(){
    var something = 17;
    //can use something inside here
}());

//but not here anymore

由于立即援引该职能,因此时间分配没有差别(在最后<代码>( bit)中)。

问题回答

自动生成的匿名功能将立即引发内部的情况,这与拖延守则毫无关系。

To make the code block inside be executed after the DOM is ready, you have to have DOMready listener. I guess the code you mentioned Event.observe(document, dom:loaded , function() { ... } is the one.
