从下面的代码中， response.data; //this piece of code gives JSON data response.data; //this piece of code gives JSON data我如何才能从此处本身删除html标签，以便可以通过$scope.test = a发送它？

app.controller('myCtrl', function($scope, $http) {
    $http({
        method : "GET",
        url : "http://webservice.somewebsite.com/exercise/show/pid/107/mid/108/"
    }).then(function mySucces(response) { 
        var a=response.data;  //this gives JSON data as shown above, 
        $scope.test = a
    }, function myError(response) { 
        $scope.test = response.statusText;
    }); 
});

我尝试了这个$scope.test = a.replace(/<\\/?[^>]+>/gi, '')但是代码停止了工作

带有HTML代码的JSON数据在UI上看起来很糟糕

Answer 1

尝试创建角度过滤器以删除标签。 检查此angularjs以输出纯文本而不是html

我没有在您的JSON中看到任何html标签吗？ 您是否发布了完整的回复？

Answer 2

我认为这个问题是，您试图替换一个对象a而不是实际上包含所需信息的介绍字符串a[i].introduction 。

因此，可以用以下方式替换它： $scope.test = toValidData(a);

function toValidData(data) {
  data.articleList.forEach(function(article) {
    article.introduction = String(article.introduction)
        .replace(/<[^>]+>/gm, '')
        .replace(/&nbsp;/g, ' ')
        .replace(/&rsquo;/, '\'')
        .replace(/(&ldquo;)|(&rdquo;)/g, '"');
  });
  return data;
}

只是附带说明，如果您想实际显示HTML，则可以使用ngSanitize 。 例：
