$ .ajax将[]附加到密钥 [英] $.ajax appending [ ] to the key

问题描述

我正在使用Jquery 1.9.1.在发送ajax数据时遇到问题，该数据之一在其中包含数组数据. 这是我的代码:

I am using Jquery 1.9.1. Having problem in sending ajax data which has array data in one of the key. This is my code:

var obj = {"param1": 1, "param2": 2, "param3": [1, 2]};
$.ajax({
    url : url,
    type: "POST",
    data: obj,
    success: function(){}
});

但是当我在开发人员工具的网络面板中检查标题时.它显示为:

But when I checked headers in network panel of developer tool. It is displayed as this:

 "param1": 1,
 "param2": 2, 
 **"param3[]"**: [1]
 **"param3[]"**: [2]

为什么要将[]添加到param3键?有人有什么主意吗?

Why it is adding [] to the param3 key? Anyone has any idea?

我以前用过$.ajax，这是它第一次像这样发送.

I have used $.ajax before, this the first time it is sending like this.

推荐答案

jQuery 1.4中添加了方括号(即[])来处理多维数组.如果要删除此选项，则应将传统选项设置为true，如下所示:

The square bracket (i.e. []) added in jquery 1.4 to handle the multiple dimension array. If you want to remove this you should set the traditional option to true, as shown below:

$.ajaxSettings({traditional: true});
