在Ex pression AngularJS前pression [英] AngularJS Expression in Expression

问题描述

有没有办法让AngularJS模型数据中评估一个前pression？

Is there a way to have AngularJS evaluate an expression within model data?

HTML

<p>
{{Txt}}
</p>

结果

型号：

    { 
     Txt: "This is some text {{Rest}}"
    }

    {
      Rest: "and this is the rest of it."
    }

最终的结果将是：这是一些文本，这是它的其余部分

推荐答案

您可以使用 $插值服务插值字符串...

You can use the $interpolate service to interpolate the string...

function ctrl ($scope, $interpolate) {
    $scope.Txt = "This is some text {{Rest}}";
    $scope.Rest = "and this is the rest of it.";
    $scope.interpolate = function (value) {
        return $interpolate(value)($scope);
    };
}

---

<div ng-app ng-controller="ctrl">
    <input ng-model="Txt" size="60" />
    <p>{{ Txt }}</p>
    <p>{{ interpolate(Txt) }}</p>
</div>
