一个页面有多个ng-app 注意几点

2015-12-16 14:53 471 查看

1.一个页面会自动加载第一个ng-app

2.如果想启动其它ng-app，需要通过下列代码的红色部分来启动，此时一共启动了2个ng-app

3.特别注意：代码红色部分一定要放在最后，比如，不能放在蓝色代码之前，否则会出错

4.一个ng-app可以有多个controller

5.$scope的范围局限于每一个controller中

<!DOCTYPE html>

<html>

<script src="http://apps.bdimg.com/libs/angular.js/1.3.9/angular.min.js"></script>

<body>

<div id="app1" ng-app="myApp">
<span ng-controller="myCtrl">{{ firstName + " " + lastName }}</span>
<br>
<span ng-controller="yourCtrl">{{ secondName + " " + thirdName + (1 + 2) }}</span>

</div>

<br>

<div id="app2" ng-app="yourApp" ng-controller="yourCtrl">
{{1 + 2}}
{{ secondName + " " + thirdName }}

</div>

<script>

var app = angular.module("myApp", []);

app.controller("myCtrl", function($scope) {

$scope.firstName = "John";

$scope.lastName = "Doe";

});

app.controller("yourCtrl", function($scope) {
$scope.secondName = "xiaoming";
$scope.thirdName = "daming";

});

var app1 = angular.module('yourApp', []);

app1.controller("yourCtrl", function($scope) {
$scope.secondName = "yitianjian";
$scope.thirdName = "tulongdao";

});

angular.bootstrap(document.getElementById("app2"), ['yourApp']);

</script>

</body>

</html>
