Question

我有一个案例，我希望将字符串与作用域定义的变量连接起来，如下所示：

$scope.variable1 = "Test Name";
$scope.variable2 = "Test 2 Name";

<a href="#">{{variable1? "({{variable1}})" : variable2}}</a>

我想在设置variable1然后显示＆＃34;（variable1）＆＃34;否则＆＃34;变量2＆＃34;。

Answer 1

变化：

<a href="#">{{variable1? "({{variable1}})" : variable2}}</a>

要：

<a href="#">{{variable1 ? "(" + variable1 + ")" : variable2}}</a>

Answer 2

试试{{variable1？＆＃39;（＆＃39; +变量1 +＆＃39;）＆＃39; ：variable2}}

Answer 3

试试这个。

    </div>

    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function ($scope) {
            $scope.variable1 = "Test Name";
            $scope.variable2 = "Test 2 Name";
        });
