JQuery每日函数：核心jQuery(callback)

 

$(document).ready()的简写。

允许你绑定一个在DOM文档载入完成后执行的函数。这个函数的作用如同$(document).ready()一样，只不过用这个函数时，需要把页面中所有需要在 DOM 加载完成时执行的$()操作符都包装到其中来。从技术上来说，这个函数是可链接的－－但真正以这种方式链接的情况并不多。

你可以在一个页面中使用任意多个$(document).ready事件。

参考 ready(Function) 获取更多 ready 事件的信息。

A shorthand for $(document).ready().

Allows you to bind a function to be executed when the DOM document has finished loading. This function behaves just like $(document).ready(), in that it should be used to wrap other $() operations on your page that depend on the DOM being ready to be operated on. While this function is, technically, chainable - there really isn't much use for chaining against it.

You can have as many $(document).ready events on your page as you like.

See ready(Function) for details about the ready event.

返回值

Uses both the shortcut for $(document).ready() and the argument to write failsafe jQuery code using the $ alias, without relying on the global alias.

jQuery 代码:

jQuery(function($) {
// Your code using failsafe $ alias here...
});
