jQuery $.proxy() 方法

❮ jQuery 事件方法

示例

在 objPerson 内部强制执行 "test" 函数的上下文

$("button").click($.proxy(objPerson, "test"));
亲自试一试 »

定义和用法

$.proxy 方法接收一个现有的函数并返回一个具有特定上下文的新函数。

此方法通常用于将事件附加到元素,其中上下文指向另一个对象。

提示:如果您绑定从 $.proxy 返回的函数,则即使传递原始函数,jQuery 仍将取消绑定正确的函数。


语法 1

$(选择器).proxy(函数,上下文) 试一试

语法 2

$(选择器).proxy(上下文,名称) 试一试

参数 描述
function 要调用的现有函数
context 函数所在的对象的名称
name 上下文将更改的现有函数(应为上下文对象的属性)。
