它是Karma（在shell中运行的AngularJS测试实用程序）的输出，它看起来像是url编码的。我tried to decode it in jsFiddle使用了javascript decodeURIComponent函数，但它不起作用并抛出错误（在Inspector中可见）＆＃34; URI格式错误＆＃34;。该字符串实际上不是URI，而是一组嵌套的URI和文本，并且已经编码。

如何解码？

您首先需要删除所有新行＆＃34;清理＆＃34; 您的string。

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);
    }
}]);

（我已根据以下answer完成此操作）

之后您将获得正确的输出：
