Question

这是我的异步方法：

function getAlbumCovers() {
        //first check to see if profile pics already exist in user model

        //create a collection
        var usersCollection = Alloy.Collections.user;

        facebookModule.requestWithGraphPath('me/albums', {
            fields : 'id,name,cover_photo,count,created_time'
        }, 'GET', function(graphResp) {
            //show view indicator before data is fetched
            $.view_indicator.visible = true;
            if (graphResp.success) {
                if (graphResp.result) {

                    var rows = [];
                    var data = JSON.parse(graphResp.result).data;
                    var i=0;

                    for (x in data) {
                        Ti.API.debug(JSON.stringify(data[x]));


                            var Albums = String.format("%s (%d)", data[x].name, data[x].count);
                            console.log(Albums);

                            var row = Titanium.UI.createTableViewRow({
                                width : '100%',
                                height : 'auto'
                            });
                            var image = Titanium.UI.createImageView({
                                image : "https://graph.facebook.com/" + (data[x].cover_photo || 0) + "/picture?access_token=" + Ti.Facebook.accessToken,
                                top : 0,
                                left : 0,
                                width : 100,
                                height : 100
                            });
                            var title = Titanium.UI.createLabel({
                                text : test,
                                top : 0,
                                left : 110,
                                width : 'auto',
                                height : 'auto'
                            });
                            row.add(image);
                            row.add(title);
                            rows.push(row);

                    }

                    console.log(rows);

                    //set table rows
                    $.tableview.setData(rows);

                    //end
                    $.view_indicator.visible = false;
                }




            } else {
                if (e.error) {
                    alert(e.error);
                } else {
                    alert("Unkown result");
                }
            }
        });

    }

问题，这是console.log(rows);的输出（如果我继续关闭并重新打开窗口）：

有时这行代码会随机失败，导致：

var Albums = String.format("%s (%d)", data[x].name, data[x].count);

我不知道为什么会发生这种情况，或者为什么表格中的数据表现不正常。任何想法，干杯。

Answer 1

String.format("%s (%d)", data[x].name, data[x].count);

这就是造成这个错误的原因。您可以通过将两个不同的字符串连接在一起来纠正它，一个用于计数，另一个用于名称

facebook模块，获取数据时的错误？
