您可以使用 flex 非常轻松地更改 HTML 元素的顺序。let changeOrder = () => {   const stackOrder = [{name: "A", order: 3}, {name: "B", order: 1}, {name: "C", order: 2}];       for (let item of stackOrder) {          $('#' + item.name)[0].style.order = item.order;       }};    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>    <div id="container" style="display: flex; flex-direction: column;">        <div id="A"> Form elements for A</div>        <div id="B"> Elements that go to B</div>        <div id="C"> CCC ccAadas</div></div><input type="button" value="ascending" onclick="changeOrder()">

您可以使用lodash库来排序结果，请考虑以下内容。假设list您从数据库返回的内容，请使用该_.orderBy函数并选择您想要排序的字段const _ = require('lodash') .... const list = [{name: "A", order: 3}, {name: "C", order: 2}, {name: "B", order: 1}] const sorted = _.orderBy(list, 'name')

首先，您可以根据顺序对数组进行排序order.sort((a, b) => {    return a.order - b.order;});完成后，循环遍历数组，在每次迭代期间创建一个 div 并将其附加到主容器。for (let i = 0; i < order.length; i++) {  let div = document.createElement("div");  div.id = order[i].name;  div.innerText = `This is ${order[i].name} div`; // for displaying test purposes  document.getElementById('main').appendChild(div);}完整示例在这里： https: //jsfiddle.net/bg7sh2rx/

您可以在 Angular JS 中使用具有 ng-repeat 功能的自定义排序。下面是工作示例。<!DOCTYPE html><html><script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script><body ng-app="myApp" ng-controller="myCtrl"><h1 ng-repeat="x in records | orderBY:'order'">{{x.name}}</h1><script>var app = angular.module("myApp", []);app.filter('orderBY', function(){ return function(input, attribute) {    if (!angular.isObject(input)) return input;    var array = [];    for(var objectKey in input) {        array.push(input[objectKey]);    }    array.sort(function(a, b){        a = parseInt(a[attribute]);        b = parseInt(b[attribute]);        return a - b;    });    return array; }});app.controller("myCtrl", function($scope) {  $scope.records =[{name: "A", order: 3}, {name: "B", order: 1}, {name: "C", order: 2}]});</script></body></html>
