javascript - 如何在字典中循环遍历字典列表并获取其中的值 - Javascript，用于 django 中的 ajax 调用

Question

我有一个 list

mylist =  [{"model": "todolist.todolist", "pk": 1, "fields": {"timezoneChoice": "Africa/Johannesburg", "user": 44, "name": "ergdsg", "discription": "dsgdsg", "dueMinutes": -61504892, "emailSent": false, "dueDate": "1899-12-11T08:20:00Z", "create_at": "2016-11-21T04:37:29.253Z"}}, {"model": "todolist.todolist", "pk": 2, "fields": {"timezoneChoice": "Africa/Johannesburg", "user": 44, "name": "ergdsg", "discription": "dsgdsg", "dueMinutes": -61504892, "emailSent": false, "dueDate": "1899-12-11T08:20:00Z", "create_at": "2016-11-21T04:38:12.525Z"}}]

我正在尝试从“字段”及其键中获取值

for (var i = 0; i < mylist.length; i++) {

                    $("#posts").prepend( "<div >" +"<h2 class='bg-info text-align-center'> Tasks" +"</h2>"
                                         + "<strong> Name: " + " "  + mylist[i].name + "</strong>"
                                         + "<strong> Task: " + " "  + mylist[i].discription + "</strong>"
                                         + "<strong> Due Date: " + " "  + mylist[i].dueDate + "</strong>"
                                         + "<strong> Mins before due: " + " "  + mylist[i].dueMinutes + "</strong>"
                                         + "<strong> TimeZone: " + " "  + mylist[i].timezoneChoice + "</strong>"
                                         + "<hr>" +"</div>")
                                },

我该怎么做。拜托，我真的需要帮助，并且一整天都在挣扎。我已经阅读了有关 javascript 和字典的内容，但我无法访问循环中所需的字典值。 ？如果有人能给出代码示例，我将非常感激。

谢谢

在循环中，只需将 mylist[i] 更改为 mylist[i][fields']，

for (var i = 0; i < mylist.length; i++) {

                $("#posts").prepend( "<div >" +"<h2 class='bg-info text-align-center'> Tasks" +"</h2>"
                                     + "<strong> Name: " + " "  + mylist[i]['fields'].name + "</strong>"
                                     + "<strong> Task: " + " "  + mylist[i]['fields'].discription + "</strong>"
                                     + "<strong> Due Date: " + " "  + mylist[i]['fields'].dueDate + "</strong>"
                                     + "<strong> Mins before due: " + " "  + mylist[i]['fields'].dueMinutes + "</strong>"
                                     + "<strong> TimeZone: " + " "  + mylist[i]['fields'].timezoneChoice + "</strong>"
                                     + "<hr>" +"</div>")
                            }
