Question

此代码无效。直接打印{{name |大写}} ..

你能帮助我吗？

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>

    <body ng-app="myApp">
    <p>Name:<input type="text" ng-model="name">
    </p>
    <h3>{{ name | uppercase }}</h3>

Answer 1

您的 ng-controller 缺失

试试这个：

<div ng-app="myApp" ng-controller="caseCtrl">
<input type="text" ng-model="txt" />
<h3>{{txt | uppercase}}</h3>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('caseCtrl', function($scope) {
    $scope.txt = "Hello World!";
});
</script>

Angular JS大写不起作用
