How to send js array in Ajax
提问by Vivek
I have created a JS array like this var detailsArr = new Array();and pushing some data into this array.
我已经创建了一个这样的 JS 数组var detailsArr = new Array();并将一些数据推送到这个数组中。
Now i push this array via Ajax to my Spring Controller like this
现在我通过 Ajax 将这个数组推送到我的 Spring Controller 中
$.ajax({
type: "POST",
url: "submit",
data: ({detailsArr : detailsArr }),
success: function(html){
alert( "Submitted");
}
});
At the Spring Controller side , i receive this array through the @RequestBodyannotation. The Spring Controller method signature looks like this
在 Spring Controller 端，我通过@RequestBody注释接收到这个数组。Spring Controller 方法签名如下所示
public String submit(@RequestBody String body)
But the array when received at the Spring Controller side is basically a String of this format
但是在Spring Controller端接收到的数组基本上是这种格式的String
detailsArr[]=add&detailsArr[]=test1&detailsArr[]=test2&detailsArr[]=test3
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.
我必须手动拆分此字符串才能获取值，这是一个繁琐的过程。有什么方法可以按原样获取数组，以便我只需遍历它即可获取值。

you should pass your array to server in json format. And convert it by using Json to object converter. you can use Gson.
您应该以 json 格式将数组传递给服务器。并使用 Json 将其转换为对象转换器。你可以使用Gson.
client side:
客户端：
$.ajax({
type: "POST",
url: "submit",
data:JSON.stringify(detailsArr),
success: function(html){
alert( "Submitted");
}
});
server side :
服务器端 ：
public String submit(@RequestBody String body){
//convert body to array using JSONLib, FlexJSON or Gson
}

When passing it to your controller, pass it like this:
将它传递给您的控制器时，请像这样传递它：
data:JSON.stringify(detailsArr);
At your controller, you can then decode the JSON received.
在您的控制器上，您可以解码收到的 JSON。
