AngularJS Ng-repeat 没有按预期工作 [英] AngularJS Ng-repeat is not working as expected
问题描述
我遇到了一个奇怪的问题，我可以访问来自我的范围作为数据模型的所有元素，也可以在 Chrome 控制台中看到范围元素，但是当我尝试在 ng-repeat 语句中使用该模型时它不起作用，它只是不循环遍历 vm.menu.items.下面是我的简单代码:
<div ng-controller="app.views.layout.header as vm"><p>{{vm.currentMenuName}} {{vm.menu.items[0].displayName}} {{vm.menu.items[1].displayName}}</p>**<<----- 它有效！**<ul><li ng-repeat="vm.menu.items 中的menuItem"><span>不工作！</span>{{menuItem.displayName}}我对 angular 还是很陌生，因此将不胜感激为我指明正确方向的任何帮助.
我删除了vm".在您的 html 中，一切都按预期工作
<div ng-controller="app.views.layout.header as vm"><p>{{currentMenuName}} {{menu.items[0].displayName}} {{menu.items[1].displayName}}</p><ul><li ng-repeat="menuItem in menu.items"><span>不工作！</span>{{menuItem.displayName}}http://plnkr.co/edit/1BtC8p1ViqKXSbCWE3Kj?p=preview
或者您可以在您的控制器中使用this"而不是 $scope(参见 http://plnkr.co/edit/1BtC8p1ViqKXSbCWE3Kj?p=preview
I'm having a weird issue, I can access all the elements coming from my scope as data model, also I can see the scope elements in the Chrome console, but when I try using the model within a ng-repeat statement it does not work, it just does not loop through the vm.menu.items. Below is my simple code:
<body ng-controller="mainController">
<div ng-controller="app.views.layout.header as vm">
<p>{{vm.currentMenuName}} {{vm.menu.items[0].displayName}} {{vm.menu.items[1].displayName}}</p> **<<----- IT works!**
<ul>
<li ng-repeat="menuItem in vm.menu.items">
<span>Not working! </span>{{menuItem.displayName}}
</li>
</ul>
</div>
</body>
I'm still pretty new to angular, so any help that point me into the right direction will be greatly appreciated.
I removed the 'vm.' in your html and everything works as expected
<body ng-controller="mainController">
<div ng-controller="app.views.layout.header as vm">
<p>{{currentMenuName}} {{menu.items[0].displayName}} {{menu.items[1].displayName}}</p>
<ul>
<li ng-repeat="menuItem in menu.items">
<span>Not working! </span>{{menuItem.displayName}}
</li>
</ul>
</div>

Or you can us 'this' in your controller instead of $scope (see http://plnkr.co/edit/1BtC8p1ViqKXSbCWE3Kj?p=preview
