[英]Angular JS - nesting templates (double curly brackets {{}} )
有沒有嵌套角度模板的方法?
例如具有以下變量:
$scope.myVar = 'hello {{name}}, you weigh {{weight}}'
$scope.name = '';
$scope.weight = '';
並讓html文件看起來像這樣:
<h1>{{myVar}}</h1>
<div>
Your Name:
<input ng-model="name" type="text">
</div>
<div>
Your Weight:
<input ng-model="weight" type="text">
</div>
然后讓angular從myVar動態設置名稱和權重模板嗎?
我認為您在尋找毫無意義。 您可以定義如下所示的函數,然后在標題中調用此函數。
$scope.myVar = function() {
return 'hello ' + $scope.name + ' you weigh '+ $scope.weight;
}
var app = angular.module('app',[]); app.controller('mainController',['$scope', function($scope){ $scope.name = "test"; $scope.weight = 100; $scope.myVar = function() { return 'hello ' + $scope.name + ' you weigh ' + $scope.weight; }; }]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <html> <head> </head> <body ng-app="app"> <div ng-controller="mainController"> <h1>{{myVar()}}</h1> <div> Your Name: <input ng-model="name" type="text"/> </div> <br/> <div> Your Weight: <input ng-model="weight" type="text"/> </div> </div> </body> </html>
我最終意識到自己有范圍錯誤。 因此,為解決綁定錯誤,我使用了$ interpolate。 請參閱: 如何在另一個表達式內求出angularjs表達式
當然,您會這樣做:
<h1>Hello {{name}} you weigh {{weight}}</h1>
<div>
Your Name:
<input ng-model="name" type="text">
</div>
<div>
Your Weight:
<input ng-model="weight" type="text">
</div>
