在jQuery中进行选择时如何对DOM元素进行排序? [英] How to sort DOM elements while selecting in jQuery?

问题描述

我的页面上有以下DIV:

I have the following DIVs on my page:

<div id="pi_div3">
  Div 3
</div>
<div id="pi_div2">
  Div 2
</div>
<div id="pi_div1">
  Div 1
</div>
<div id="pi_div6">
  Div 6
</div>
<div id="pi_div5">
  Div 5
</div>
<div id="pi_div4">
  Div 4
</div>

我正在尝试使用jQuery代码$("div[id*=pi_div]")选择Divs.

I am trying to select the Divs using the jQuery code $("div[id*=pi_div]").

当我在选择器上执行each()时，我需要根据其ID对div进行排序.当我遍历DIV时，顺序应为:PI_DIV1，PI_DIV2，PI_DIV3，PI_DIV4，PI_DIV5，PI_DIV6.如何在jQuery中做到这一点?

I need the divs to be sorted based on their IDs when I do an each() on the selector. When I loop through the DIVs, the order should be: PI_DIV1, PI_DIV2, PI_DIV3, PI_DIV4, PI_DIV5, PI_DIV6. How can I do that in jQuery?

推荐答案

您可以致电 .sort()，然后调用 .each()

You can call .sort() before calling .each()

$("div[id*=pi_div]").sort(function(a,b){
    if(a.id < b.id) {
        return -1;
    } else {
        return 1;
    }
}).each(function() { console.log($(this).attr("id"));});

我想知道为什么其他答案正在删除id的pi_div部分，我知道了.如果您根据字符串"进行比较，则pi_div10将排在pi_div2之前.

I was wondering why the other answers are removing the pi_div part of the id and I get it. If you compare based on the "strings" pi_div10 will come before pi_div2.
