jQuery ready函数别名 [英] jQuery ready function aliases

问题描述

对于创建新jQuery对象的所有不同方式，我有些困惑.

I'm a little confused about all the different ways to create a new jQuery object.

相关文档似乎是: http://api.jquery.com/ready/ http://api.jquery.com/jQuery/

the relevent docs seem to be: http://api.jquery.com/ready/ http://api.jquery.com/jQuery/

在这两个文档中，以下内容都是等效的(别名或不别名'$'除外):

From those two docs the following are all equivalent, (with the exception of aliasing or not aliasing '$'):

• $(document).ready(handler)
• $().ready(handler)
• $(处理程序)
• jQuery(function($){});
• jQuery(document).ready(function($){});

那是正确的吗?我有想念吗?

Is that correct? Did I miss any?

推荐答案

嗯，还有另一个.从文档中:

Well, there is another. From the docs:

也有 $(document).bind("ready"，handler). 这与ready
的行为类似 方法，但有一个例外:如果 准备就绪的事件已经触发，您 尝试.bind("ready")边界 处理程序将不会执行.

There is also $(document).bind("ready", handler). This behaves similarly to the ready
method but with one exception: If the ready event has already fired and you try to .bind("ready") the bound handler will not be executed.

其他初始化程序方法将始终运行...因此，例如，您可能会发现自己在多个文件中声明了$(document).ready(function() { //stuff }，并且该处理程序始终处于运行状态.

The other initialiser methods will always run... so you might find yourself declaring $(document).ready(function() { //stuff } in a number of files for example, and the handler is always run.

我经常会使用jQuery(document).ready(function($) {})或$(document).ready(function() {}) ...我发现它们更具可读性.

I'd go with jQuery(document).ready(function($) {}) or $(document).ready(function() {}) more often than not... I find that they're more readable.

另一种方法是在结束body标记之前调用脚本，并在脚本中执行类似的操作，

Another approach would be to call a script just before the closing body tag and in it do something like,

(function($) {
    //stuff
})(jQuery);

如果需要避免与使用$的其他库冲突.这是一个自动执行的匿名函数，它使您可以在别名范围内使用别名，而不必担心与其他库发生冲突.

if you need to avoid conflicts with other libraries using $. This is a self-executing anonymous function and it lets you use the alias in its scope without fear of conflicts from other libraries.
