过滤器无法正常工作.代码的其他部分也会中断.投掷错误过滤器：notarray.如何修复它
<head>
<link rel="stylesheet" href="style.css">
</head>
<body ng-init="items=[3,1,2,3];">
<h1>Hello Plunker!</h1>
<div >
</div>
<input type="text" ng-model="nm" />
<div ng-repeat="item in items track by $index | filter:nm" ng-hide="hide">
{{item}}
</div>
<button ng-click="hide=!hide">Toggle </button>
<button ng-click="items[items.length]=items.length">Add</button>
<script src="https://code.angularjs.org/1.4.2/angular.min.js"></script>
<script src="script.js"></script>
</body>
</html>
ng-repeat的文档说：
track by must always be the last expression
所以你需要改变这一行：
<div ng-repeat="item in items track by $index | filter:nm" ng-hide="hide">
对此：
<div ng-repeat="item in items | filter: nm track by $index" ng-hide="hide">
我知道这很模糊,而且这个人会把人赶出去.通常,文档不在您期望的页面上(例如过滤器),但仍然在逻辑位置(例如ng-repeat).它’应该’都在那里.
