问题描述
我曾尝试与以下code,但显示了控制器侧空..
I have tried with following code but shows null in the controller side..
查看:
<script>
function getme(){
debugger;
var emp = [
{ empid: 1, name: 'sasi' },
{ empid: 2, name: 'sathish'}
];
emp = JSON.stringify({ 'emp': emp });
$.ajax({
contentType: 'application/json; charset=utf-8',
dataType: 'json',
type: 'POST',
url: '/Home/getemplist',
data: JSON.stringify(emp)
});
}
</script>
<input type="button" onclick="getme();" value="Click me" />
控制器:
public void getemplist(List<Emp> emp)
{ }
Emp.cs:
public class Emp
{
public int empid { get; set; }
public string name{get;set;}
}
请帮我解决这个..
推荐答案
很多谷歌搜索后..我发现张贴的对象列表到控制器..我已经修改了一点在我的$ C $方式ç...这里是!
After a lot of searches in google.. I found the way to post the list of objects to controller.. i have modified little bit in my code... here it is!!
脚本:
var emp = [{ 'empid': 1, 'name': 'sasi' },{ 'empid': 2, 'name': 'sathish'}];
emp = JSON.stringify(emp)
$.post("/Home/getemplist/", { 'emp': emp })
控制器:
在这里,我只是改变了参数字符串类型。使用的JavaScriptSerializer可以能够将此字符串数据转换到您的类对象列表..你可以更好地理解它,如果你看到我下面的code:
Here i just changed the parameter to string type. using JavaScriptSerializer you can able to convert this string data to your class list objects.. you can understand it better if u see my code below:
public void getemplist(string emp)
{
List<Emp> personData;
JavaScriptSerializer jss = new JavaScriptSerializer();
personData = jss.Deserialize<List<Emp>>(emp);
// DO YOUR OPERATION ON LIST OBJECT
}
包括在你的控制器本(System.Web.Script.Serialization)命名空间序使用的JavaScriptSerializer类。
Include this (System.Web.Script.Serialization) namespace in your controller inorder to use the JavaScriptSerializer class.
希望这有助于!快乐编码:)
