这是 Karma(在 shell 中运行的 AngularJS 测试实用程序)的输出，看起来像是经过 url 编码的。我 tried to decode it in jsFiddle 使用 javascript decodeURIComponent 函数，但它不起作用并抛出错误(在检查器中可见)“URI 格式错误”。该字符串实际上并不是一个 URI，而是一组嵌套的 URI 和文本，并且已进行编码。

如何解码？

Answer 1

您首先需要通过删除所有新行来“清理”您的字符串。

现场演示: https://jsfiddle.net/oscarj24/4wvtdreg/

angular.module('myapp', []).controller('Decoder', ['$scope', function($scope) {
    $scope.decode = function() {
      var str = this.src;

      str = str.replace(/(\r\n|\n|\r)/gm, '');

      this.src = decodeURIComponent(str);
    }
}]);

(我是根据以下 answer 完成此操作的)

之后你将得到正确的输出:
