why angularjs ng-repeat not working
提问by Mahesha999
I am trying out the basics of AngularJS first time. I am trying out ng-repeat first time. However it is not working.
我第一次尝试 AngularJS 的基础知识。我第一次尝试 ng-repeat。但是它不起作用。
Here is a non working jsfiddle.
这是一个非工作jsfiddle。
I have written the code in single standalone HTML file as follows and also angular.js file resides in the same directory
我在单个独立的 HTML 文件中编写了如下代码，并且 angular.js 文件也位于同一目录中
<html ng-app>
<head>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript">
var users = [
{
name:"Mahesh",
description:"A geek",
age:"22"
},
{
name:"Ganesh",
description:"A nerd",
age:"25"
},
{
name:"Ramesh",
description:"A noob",
age:"27"
},
{
name:"Ketan",
description:"A psychopath",
age:"26"
},
{
name:"Niraj",
description:"Intellectual badass",
age:"29"
}
];
</script>
</head>
<body>
<div>
<div data-ng-repeat="user in users">
<h2>{{user.name}}</h2>
<div>{{user.description}}</div>
</div>
</div>
</body>
</html>

usersmust refer to a property that is accessible on the current scope. Scopes are AngularJS way of tying data from and to HTML. This is explained further in the "Model and Controller" chapter of the second tutorial page. See a working version of your Fiddle here.
users必须引用在当前范围内可访问的属性。范围是 AngularJS 将数据从 HTML 绑定到 HTML 的方式。这在第二个教程页面的“模型和控制器”一章中进一步解释。在此处查看 Fiddle 的工作版本。
HTH!
哼！

you have not define the controller such as
您尚未定义控制器，例如
myapp.controller("AppController",function($scope){
$scope.users=[
{
name:"Mahesh",
description:"A geek"
},
];
});
/// than you can call controller to the view such as below code :
/// 比你可以调用控制器到视图，如以下代码：
<body ng-controller="AppController">
<div><div data-ng-repeat="user in users">
<h2>{{user.name}}</h2>
<div>{{user.description}}</div>
</div>
</div>
</body>
