如何在Ajax中发送js数组 [英] How to send js array in Ajax

问题描述

我创建了一个像这样的 var detailsArr = new Array（）; 的JS数组，并将一些数据推送到这个数组中。

I have created a JS array like this var detailsArr = new Array(); and pushing some data into this array.

现在我将这个数组通过Ajax推送到我的Spring Controller，就像这样

Now i push this array via Ajax to my Spring Controller like this

$.ajax({
            type: "POST",
            url: "submit",
            data: ({detailsArr : detailsArr }),
            success: function(html){
              alert( "Submitted");
                }
          });

在Spring Controller端，我通过 @RequestBody <接收此数组/ code>注释。 Spring Controller方法签名看起来像这样

At the Spring Controller side , i receive this array through the @RequestBody annotation. The Spring Controller method signature looks like this

public String submit(@RequestBody String body) 

但是在Spring Controller端收到的数组基本上是这种格式的字符串

But the array when received at the Spring Controller side is basically a String of this format

detailsArr[]=add&detailsArr[]=test1&detailsArr[]=test2&detailsArr[]=test3

我必须手动拆分此String以获取值，这是一个繁琐的过程。有没有什么方法可以让我得到数组，所以我只需要迭代它来获取值。

I have to manually split this String to get the values, this is a cumbersome process. Is there any way in which I can get the array as it is , so that I just have to iterate over it to get the values.

推荐答案

您应该以json格式将数组传递给服务器。并使用Json转换为对象转换器。你可以使用 Gson 。

you should pass your array to server in json format. And convert it by using Json to object converter. you can use Gson.

客户端：

$.ajax({
            type: "POST",
            url: "submit",
            data:JSON.stringify(detailsArr),
            success: function(html){
              alert( "Submitted");
                }
          });

服务器端：

public String submit(@RequestBody String body){
//convert body to array using JSONLib, FlexJSON or Gson
}
