JQuery嵌套了这个引用 [英] JQuery nested this references

问题描述

我有一些JQuery代码如下：

I have some JQuery Code as follows:

$("#sh-zone-button-cart-menu").live("click", function(event)
{
    event.preventDefault();
    $("#sh-zone-cart-menu").toggle(0, function(){
        if($(this).is(":visible")){
            $(this).siblings(".sh-zone-button-link-menu-content").hide();
            $("#sh-zone-button-cart-menu").parent().removeClass("current");
            //need to reference (this) for $("#sh-zone-button-cart-menu") here 
        }               
    });
    $("#sh-zone-button-cart-menu").parent().toggleClass("current"); 
});

我试图从另一个子元素中访问我的初始点击的这个参考，即我会喜欢在我的live（）方法的第一个大括号之后获得这个引用。但是，我需要从另一个子元素中访问它，即在我的toggle（）方法中。

I am trying to access the this reference for my initial click from within another sub-element i.e. I would like to get the this reference that would have been available just after the first curly brace of my live() method. However, I need access to it from within another sub-element i.e. inside my toggle() method.

我该怎么做？

谢谢。

推荐答案

保存此为一个局部变量：

$("#sh-zone-button-cart-menu").live("click", function(event) {
    // This line saves the current 'this' as a local variable 
    // that can be accessed by inner functions        
    var thisInClick = this;
    event.preventDefault();
    $("#sh-zone-cart-menu").toggle(0, function(){
        if($(this).is(":visible")){
            $(this).siblings(".sh-zone-button-link-menu-content").hide();
            $("#sh-zone-button-cart-menu").parent().removeClass("current");
            //need to reference (this) for $("#sh-zone-button-cart-menu") here 
            $(thisInClick).doSomething();
        }               
    });
    $("#sh-zone-button-cart-menu").parent().toggleClass("current"); 
});
