jQuery ready() 方法

❮ jQuery 事件方法

示例

使用 ready() 使函数在文档加载后可用

$(document).ready(function(){
  $("button").click(function(){
    $("p").slideToggle();
  });
});
亲自试一试 »

定义和用法

ready 事件在 DOM(文档对象模型)加载完成后发生。

因为此事件在文档准备就绪后发生,所以它是放置所有其他 jQuery 事件和函数的好地方。就像上面的示例一样。

ready() 方法指定在 ready 事件发生时会发生什么。

提示:ready() 方法不应与 <body onload=""> 一起使用。


语法

可以使用两种语法: 

$(document).ready(function)

ready() 方法只能用于当前文档,因此不需要选择器

$(function)

参数 描述
function 必需。指定在文档加载后运行的函数
