如何将JSON数据传递给方法后面的代码(而不是Webmethod)? [英] How to pass JSON data to code behind method (not to Webmethod)?

问题描述

我有JSON数据，我需要将其传递给后面的代码并绑定到obout网格.我知道我们可以使用<WebMethod>传递数据.但是在Webmethod中，我无法将数据绑定到obout网格和任何网格.因为它是静态的webmethod.

I have JSON data which I need to pass to code behind and bind to obout grid. I know we can pass data using <WebMethod>. But in Webmethod I cannot bind the data to obout grid and any grid. because it is static webmethod.

所以现在我尝试从javascript调用方法后面的代码，并将数据作为参数传递给方法.我们该怎么做?

So Now I trying to call code behind method from javascript and pass the data as parameter to method. How can we do that?

 users = [];
 for (var i = 0; i < usersInfo.length; i++) {
          user = {
                   UserName : usersInfo[i].UserName,
                   Email : usersInfo[i].Email,
                   Status : status
          };

          users.push(user);
    }
    var results = "";
    $('#lblError').val('');
    if (users.length > 0) {
        //Pass the `users` data to ShowResults code behind method.
     }

后面的代码

public void ShowResults(List<UsersInfo> users)
{
       oboutGrid.DataSource = users;
       oboutGrid.DataBind();
}

public partial class UsersInfo
{
    public string UserName { get; set; }
    public string Email { get; set; }        
    public string Status { get; set; }
}

推荐答案

一种方法是在aspx表单上包含一个隐藏字段

one way to do this, is to include a hidden field on the aspx form

<asp:HiddenField ID="jsonDataHolder" ClientIDMode="Static" runat="server"/>

在此隐藏字段中，使用JSON.stringify将您的JSON数据添加为字符串

in this hidden field add your JSON data as a string, using JSON.stringify

$('#jsonDataHolder').val(JSON.stringify({ id: 1, name: "mohamed" }));

然后，当页面正常发布回去时，您可以访问隐藏字段，对其进行反序列化并编写代码

then when the page is normally posted back you can access the hidden field, deserilaize it and do your code

protected void btn_DOPostBack_Click(object sender, EventArgs e)
{
    string data = this.jsonDataHolder.Value;
    // desrialize json, do ur code
}
