Question

我正在尝试使用甘特图显示每个项目的任务。不幸的是，我只能显示最后一个项目（带有任务）。它忽略了其他项目。我已经在这个例子中包含了一个我正在使用的小提琴的链接。我在这做错了什么？这是我的Javascript代码：

var data = [
                                    {
                                        "project": "edo",
                                        "tasks": [
                                            {

问题在于您定义final变量的位置。在您的代码中，对final数组中的每个元素清除var final=[]变量（data）：

                            for(var i = 0; i < data.length; i++) {
                                var project = data[i].project;
                                var tasks = data[i].tasks;
                                //console.log(project);
                                var final = []; // <---- this is wrong ---->
                                for(var j=0; j < tasks.length; j++) {
                                    final.push({
                                        taskName: tasks[j].name,
                                        start: today - 2 * day,
                                        end: today + 14 * day
                                    });
                                }
                            }

应该在for循环之前定义：

                            var final = []; // This will work
                            for(var i = 0; i < data.length; i++) {
                                var project = data[i].project;
                                var tasks = data[i].tasks;
                                //console.log(project);
                                for(var j=0; j < tasks.length; j++) {
                                    final.push({
                                        taskName: tasks[j].name,
                                        start: today - 2 * day,
                                        end: today + 14 * day
                                    });
                                }
                            }
