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">

<script>

];
});
</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><!-- 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>
