数据绑定Angular js [英] Data binding in Angular js
问题描述
当我使用角度版本。
https：// ajax。 googleapis.com/ajax/libs/angularjs/1.2.0-rc.2/angular.js
我的代码工作正常。但是当我使用这个角度版本时，我的代码无法工作。
https：//ajax.googleapis。 com / ajax / libs / angularjs / 1.4.7 / angular.min.js 。
完整的HTML代码。
<！DOCTYPE html>
< html ng-app =>
< script src =https://ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular.min.js\"> ;</script>
< head>
< title> Angular Js教程< / title>
< / head>
< body>
< div ng-controller =Maincontroller>
{{message}}
< / div>
< script>
函数Maincontroller（$ scope）
{
$ scope.message =你好吗;
}
< / script>
< / body>
< / html>
我没有输出所需的数据。它只是打印。
{{message}}
从angular 1.3开始，您无法在全局范围内声明控制器。
<重写你的控制器的声明
MainController //声明模块
angular.module（'myApp'，[]）;
//声明控制器
angular.module（'myApp'）.controller（'MainController'，function（$ scope）{
$ scope.message =Hii你好吗;
}）;
关于上述更改，请将< html ng-app = > with < html ng-app =myApp>
When i am using angular version this. "https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.2/angular.js" my code works fine. but when i am using this angular version my code is not working. "https://ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular.min.js".
Full HTML code.
<!DOCTYPE html>
<html ng-app="">
<script src= "https://ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular.min.js"></script>
<head>

</head>
<body>
<div ng-controller="Maincontroller">
{{message}}
</div>
<script>
function Maincontroller($scope)
{
$scope.message = "Hii how are you";
}
</script>
</body>
</html>
I didn't the required output. It simply prints.
{{message}}
Starting from angular 1.3 you can't declare controllers in the global scope.
Rewrite the declaration of your controller MainController
// Declaration of the module
angular.module('myApp', []);
// Declaration of the controller
angular.module('myApp').controller('MainController', function ($scope) {
$scope.message = "Hii how are you";
});
Regarding to the above changes, replace <html ng-app=""> with <html ng-app="myApp">
