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>
