我在 aspx 页面中有一个文本框。从那我需要在Json函数中发送文本框的文本为此我在服务器端有一个方法。
[WebMethod]
public static OfficeDetails[] BindSearchDatatable(string officename)
{
DataTable dt = new DataTable();
List<OfficeDetails> details = new List<OfficeDetails>();
using (SqlConnection con = new SqlConnection(@"Data Source=GTL--7\SQLEXPRESS;Initial Catalog=master;Integrated Security=True"))
{
using (SqlCommand cmd = new SqlCommand("select OfficeName,City,Country from Office where OfficeName like '%" + officename + "%'", con))
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
foreach (DataRow dtrow in dt.Rows)
{
OfficeDetails Office = new OfficeDetails();
Office.OfficeName = dtrow["OfficeName"].ToString();
Office.City = dtrow["City"].ToString();
Office.Country = dtrow["Country"].ToString();
details.Add(Office);
}
}
}
return details.ToArray();
}
在 .aspx 页面中我有
$('#btnSearch').click
(
function () {
var searchtext = $("#txtSearch").val();
alert(searchtext);
$.ajax(
{
type: "POST",
url: "Gridview.aspx/BindSearchDatatable",
data: "{officename : New}",
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function (data) {
for (var i = 0; i < data.d.length; i++) {
$("#gvDetails").append("<tr><td>" + data.d[i].OfficeName + "</td><td>" + data.d[i].City + "</td><td>" + data.d[i].Country + "</td></tr>");
}
},
error: function (x, e) {
alert("The call to the server side failed. " + x.responseText);
}
}
);
return false;
}
);
现在我的问题是我在数据中发送参数,但我收到一个错误函数运行良好。我已经在没有参数的情况下对其进行了测试,所以它运行良好。所以我的事情是在函数中传递文本框的文本值时发生了一些错误.
