Question

我有这样的json数组：

     {"error":false,
 "message":"",
 "Album_list":[{"Album":{"id":"27","user_id":"46","title":"Internal","status":"1","time":"","created":"2016-05-02 17:20:27","modified":"2016-05-02 17:20:27"}},
    {"Album":{"id":"30","user_id":"46","title":"efdrhty","status":"1","time":"","created":"2016-05-04 08:52:12","modified":"2016-05-04 08:52:12"}},
    {"Album":{"id":"37","user_id":"46","title":"external","status":"1","time":"","created":"2016-05-06 08:04:55","modified":"2016-05-06 08:04:55"}},
    {"Album":{"id":"38","user_id":"46","title":"James Jobs" ,"status":"1","time":"","created":"2016-05-17 09:40:41","modified":"2016-05-17 09:40:41"}},
    {"Album":{"id":"41","user_id":"46","title":"17th May 2016","status":"1","time":"","created":"2016-05-17 10:20 :10","modified":"2016-05-17 10:20:10"}}]}

现在，在success函数中，我需要循环中的这个Album_list数据。

我试试这个，但我无法正确使用

Javascript代码：

success: function (response) {

            if (response.error == true) {
                console.log(response.message);
            } else {
                content += '<div class="ui-grid-b gallery-sec">';

                for (img in response.Album_list) {
                    console.log(img);  

                    content += '<div class="ui-block-b gallery-sec">' +
                        '<div class="gallery-thumb-col">' +
                        '<div class="gallery-thumb">' +
                        '<img src="images/blue-box-logo.png" alt="">' +
                        '</div>' +
                        '<div class="full">' +
                        '<h2>'+img.Album.title+'</h2>' +  //I need the title of album here
                    '</div>' +
                    '<p>2 Photos</p>' +
                    '<div class="ftr-bg">' +
                        '<i class="fa fa-trash-o" aria-hidden="true"></i></div>' +
                    '</div>' +
                    '</div>';

                }
                content += '</div>';
                $('#gallery .page-content').html(content);

            }
        }

console.log(img);得0，然后是1，然后是4，但我需要Album数组。

Answer 1

使用此：

public ActionResult Index() //Wait, got an exception, cannot use more than one 'Index()'
{
    bindCombo();

    return this.View();
}

[HttpPost]
public ActionResult Index(HttpPostedFileBase file) //Same problem, how do i fix?
{
    ModelVariables mv = new ModelVariables();

    if (file != null && file.ContentLength > 0)
    {
        mv.fileSubmit = Path.GetFileName(file.FileName);
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
        file.SaveAs(path);
    }

    return RedirectToAction("Index", mv);
}

Documentation about for in loop

因为我看到你正在使用jQuery。你可以这样做：

for (var i = 0; i < response.Album_list.length; i++) {
   var album = response.Album_list[i];

   console.log(album);
}

Answer 2

替换

for (img in response.Album_list) {
    // code here
}

与

response.Album_list.forEach(function (img) {
    // code here
});

因为img不是元素，而是索引的变量。

Answer 3

您也可以尝试：

for (var index in response.Album_list) {
    img = response.Album_list[index];

    // rest of the code as it it
}

用循环处理javascript中的json数组
