c# - json函数返回值但值未显示在mvc的文本框中
问题描述
您好，我想在单击编辑按钮时填充文本，但值未填写在文本框中，当我调试此代码时，json 函数返回值以及在 javascript 代码中显示的值，但是当弹出模型显示时，值不显示在文本框中。任何人都告诉我哪里错了，这段代码有什么问题。
json 函数
#region Select Requisition Main Select
public JsonResult mRequisitionmain_Select(Int64 Req_ID)
{
try
{
Requisition mReq = new Requisition();
con = new SqlConnection(constring);
SqlCommand cmd = new SqlCommand("Select Req_ID,ReqNo,Comp_ID, GL_Year,ReqDate,Job,ApprovedBy,UserName, IsApproved from RequisitionMain where Req_ID='" + Req_ID + "'", con);
cmd.CommandType = CommandType.Text;
con.Open();
DataTable mDT = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(mDT);
mReq.Req_ID = mDT.Rows[0]["Req_ID"].ToString();
mReq.ReqNo = mDT.Rows[0]["ReqNo"].ToString();
mReq.Comp_ID = 1;
mReq.GL_Year = "2018-2019";

mReq.Approvedby = mDT.Rows[0]["ApprovedBy"].ToString();
mReq.Username = Session["AgentName"].ToString();
mReq.IsApproved = Convert.ToBoolean(mDT.Rows[0]["IsApproved"]);
con.Close();
return Json(mReq, JsonRequestBehavior.AllowGet);
