1、问题背景
AngularJS利用ng-if指令来判断对象元素是否为空
2、实现源码
<!DOCTYPE html><html ng-app="ifApp"><head><meta charset="UTF-8"><title>AngularJS之ng-if指令</title><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script><script>var app = angular.module("ifApp",[]);app.controller("ifController",function($scope){$scope.person = {name:{username:"张三",sex:"男",age:"23"},scores:{item:"语文",score:"123"}};});</script></head><body ng-controller="ifController"><div ng-if="person != null"><div ng-repeat="p in person"><div ng-if="person.name != null"><label>{{p.username}}</label></div></div></div></body></html>3、实现结果
