本文介绍如何使用AngularJS动态生成具有特定ID的div元素。通过定义一个包含多个div ID的数组，利用ng-repeat指令遍历数组并为每个div元素分配ID。此方法适用于需要动态创建多个具有唯一标识符的DOM元素的场景。

1、问题背景

给定一个数组对象，里面是div的id；循环生成div元素，并给id赋值

2、实现源码

<!DOCTYPE html><html> <head>  <meta charset="UTF-8">  <title>AngularJS动态生成div的ID</title>  <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>  <script>   var app = angular.module("idApp",[]);   app.controller("idCon",function($scope){    $scope.divIds = [     {divId:"chartId1"},     {divId:"chartId2"},     {divId:"chartId3"},     {divId:"chartId4"},     {divId:"chartId5"}    ];   });  </script> </head> <body ng-app="idApp" ng-controller="idCon">  <div ng-repeat="chart in divIds">   <div id="{{chart.divId}}">{{chart.divId}}</div>  </div> </body></html>

3、实现结果

<html><head><style type="text/css">@charset "UTF-8";[ng\:cloak],[ng-cloak],[data-ng-cloak],[x-ng-cloak],.ng-cloak,.x-ng-cloak,.ng-hide:not(.ng-hide-animate){display:none !important;}ng\:form{display:block;}.ng-animate-shim{visibility:hidden;}.ng-anchor{position:absolute;}</style>  <meta charset="UTF-8">  <title>angularJS动态生成div的ID</title>  <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>  <script>   var app = angular.module("idApp",[]);   app.controller("idCon",function($scope){    $scope.divIds = [     {divId:"chartId1"},     {divId:"chartId2"},     {divId:"chartId3"},     {divId:"chartId4"},     {divId:"chartId5"}    ];   });  </script> </head> <body ng-controller="idCon" ng-app="idApp" class="ng-scope">  <!-- ngRepeat: chart in divIds --><div ng-repeat="chart in divIds" class="ng-scope">   <div id="chartId1" class="ng-binding">chartId1</div>  </div><!-- end ngRepeat: chart in divIds --><div ng-repeat="chart in divIds" class="ng-scope">   <div id="chartId2" class="ng-binding">chartId2</div>  </div><!-- end ngRepeat: chart in divIds --><div ng-repeat="chart in divIds" class="ng-scope">   <div id="chartId3" class="ng-binding">chartId3</div>  </div><!-- end ngRepeat: chart in divIds --><div ng-repeat="chart in divIds" class="ng-scope">   <div id="chartId4" class="ng-binding">chartId4</div>  </div><!-- end ngRepeat: chart in divIds --><div ng-repeat="chart in divIds" class="ng-scope">   <div id="chartId5" class="ng-binding">chartId5</div>  </div><!-- end ngRepeat: chart in divIds --> </body></html>
