<div ng-app="myApp"> <div ng-controller="firstController">
{{name}} </div> </div>
<script type="text/javascript">
var app = angular.module("myApp", []);
app.controller('firstController',['$scope',function($scope){ setTimeout(function(){ $scope.$apply(function(){
$scope.name='李四';
}); }, 2000);
$scope.name='张三'; }]); </script> </body>
</html>
2s 后更新name的值为李四
2. ng-click使用, 如下图,定义了一个changeName方法,点击后修改名字为王五
timeout的使用,如下图,不需要再写setTimeout.
