Pass array to code behind from jquery ajax
提问by Rajaram Shelar
I have to pass two dimensional array to the page method written at code behind of the web page in asp.net I have a variable objListas a two dimensional array. I used following code for achieving this with no success and page method is not called.
我必须将二维数组传递给在 asp.net 中网页后面的代码中编写的页面方法我有一个变量objList作为二维数组。我使用以下代码实现此目的但没有成功，并且未调用页面方法。
JAVASCRIPT
爪哇脚本
function BindTable(objList) {
$.ajax(
{
url: "CompCommonQues.aspx/SaveData",
contentType: "application/json; charset=utf-8",
dataType: "json",
type: "POST",
data: { data: objList },
success: function (data) {
//Success code here
},
error: function () { }
});
}
CODE BEHIND .CS File
.CS 文件背后的代码
[WebMethod]
public static string SaveData(string[,] data)
{
string[,] mystring = data;
return "saved";
}
There is method like JSON.stringify(objList) to pass the json array to code behind but couldn't implement this. A simple call wihtout array working for me like
有像 JSON.stringify(objList) 这样的方法可以将 json 数组传递给后面的代码，但无法实现。一个没有数组的简单调用对我来说像
data: "{ 'data':'this is string' }",
and in code behind
并在后面的代码中
[WebMethod]
public static string SaveData(string data)
{
string mystring = data;
return "saved";
}
There is problem in passing data. Can you assist me how to pass it for arrays?

Try the correct JSON notation in JavaScript
在 JavaScript 中尝试正确的 JSON 表示法
var objList = new Array();
objList.push(new Array("a","b"));
objList.push(new Array("a", "b"));
objList.push(new Array("a", "b"));
$.ajax({
type: "POST",
url: "copyproduct.aspx/SaveDate",
data: "{'data':'" + JSON.stringify(objList) + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
alert(msg.d);
}
});
In code behind, you can deserialize with JavaScriptSerializer (System.Web.Script.Serialization)
在后面的代码中，您可以使用 JavaScriptSerializer (System.Web.Script.Serialization) 进行反序列化
[WebMethod()]
public static string SaveDate(string data)
{
JavaScriptSerializer json = new JavaScriptSerializer();
List<string[]> mystring = json.Deserialize<List<string[]>>(data);
return "saved";
}
I had to deserialize to a generic list of a string array because you can't deserialize to a string (check: http://forums.asp.net/t/1713640.aspx/1)
我不得不反序列化为字符串数组的通用列表，因为您无法反序列化为字符串（检查：http: //forums.asp.net/t/1713640.aspx/1）
