1、问题背景
给定一个数组对象，里面是p的id；循环生成p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p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.pIds = [
{pId:"chartId1"},
{pId:"chartId2"},
{pId:"chartId3"},
{pId:"chartId4"},
{pId:"chartId5"}
];
});
</script>
</head>
<body ng-app="idApp" ng-controller="idCon">
<p ng-repeat="chart in pIds">
<p id="{{chart.pId}}">{{chart.pId}}</p>
</p>
</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 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.pIds = [
{pId:"chartId1"},
{pId:"chartId2"},
{pId:"chartId3"},
{pId:"chartId4"},
{pId:"chartId5"}
];
});
</script>
</head>
<body ng-controller="idCon" ng-app="idApp" class="ng-scope">
<!-- ngRepeat: chart in pIds --><p ng-repeat="chart in pIds" class="ng-scope">
<p id="chartId1" class="ng-binding">chartId1</p>
</p><!-- end ngRepeat: chart in pIds --><p ng-repeat="chart in pIds" class="ng-scope">
<p id="chartId2" class="ng-binding">chartId2</p>
</p><!-- end ngRepeat: chart in pIds --><p ng-repeat="chart in pIds" class="ng-scope">
<p id="chartId3" class="ng-binding">chartId3</p>
</p><!-- end ngRepeat: chart in pIds --><p ng-repeat="chart in pIds" class="ng-scope">
<p id="chartId4" class="ng-binding">chartId4</p>
</p><!-- end ngRepeat: chart in pIds --><p ng-repeat="chart in pIds" class="ng-scope">
<p id="chartId5" class="ng-binding">chartId5</p>
</p><!-- end ngRepeat: chart in pIds -->
</body></html>
