Question

我试图在div中显示一些数字，如下所示

 <div ng-init="range=[1,10,3,4,5]" ng-repeat="n in range" >
  {{n}}
 </div>

未在range

中显示数字

Answer 1

在ng-repeat之前初始化

<div ng-init="range=[1,10,3,4,5]" >
<div ng-repeat="n in range" >
  {{n}}
 </div> 
</div>

Answer 3

ng-init只能用于别名：https://docs.angularjs.org/api/ng/directive/ngInit

您是否可以初始化控制器中的范围值？

Answer 4

试试这个

<!DOCTYPE html>
<html ng-app>
<head>
    <title>AngularJS</title>
    <script type="text/javascript"
        src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>

</head>
<body>
    <ANY ng-init="range=[1,10,3,4,5]">
    </ANY>
    <div ng-repeat="n in range">
    {{n}}
    </div>
</body>
</html>

ng-init使用ng-repeat不起作用
