javascript - 针对 jQuery 中每个循环的嵌套 $(this)

Question

我试图弄清楚，在遍历某些列表项时，如何定位嵌套 foreach 循环中的每个“$(this)”等价物。这是我的问题的示例:

$('li').each(function(){
        // I believe $(this) would target each li item...
    $(this).children("li").each(function(){
        // ... but how can I target each of these li items? Doesn't $(this) target the original loop?
    });
});

Answer 1

$('li').each(function(){
    var $this = $(this);
    $this.children("li").each(function(){
        $this; // parent li
        this; // child li
    });
});
