【问题描述】:
我想在不使用 runat="server" 的情况下将输入标签 type="text" 设置为在按钮单击事件中不可见/可见
下面是编码
$(document).ready(function () {
SearchText();
});
function SearchText()
{
$(".autosuggest").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CalenderDetails.aspx/GetAutoCompleteData",
data: "{'Col3':'" + document.getElementById('txtSearch').value + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
});
}
});
}
</script>
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" />
<br />
<input type="text" id="txtSearch" class="autosuggest" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" >
<ContentTemplate>
<asp:Label ID="Label3" runat="server" Text="Label"></asp:Label>
<br />
<br />
<asp:GridView ID="Gr
idView1" runat="server" AllowPaging="True" PageSize="20" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowDataBound="GridView1_RowDataBound">
<HeaderStyle BackColor="#FFCC99" />
</asp:GridView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" EventName="PageIndexChanging" />
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
背后的代码
[WebMethod]
public static List<string> GetAutoCompleteData(string Col3)
{
List<string> result = new List<string>();
if ((dtClone != null) && (dtClone.Rows.Count > 0))
{
DataRow[] foundRows;
string expression = "Col3 LIKE '%" + Col3 + "%'";
// Use the Select method to find all rows matching the filter.
foundRows = dtClone.Select(expression);
for (int i = 0; i < foundRows.Length; i++)
result.Add(foundRows[i][2].ToString());
}
return result;
}
如果我使用 runat="server" 我可以让它可见/不可见,但是 ajax 调用将不会执行搜索操作
谁能告诉我如何克服这个问题?
【问题讨论】:
-
你可以在代码后面调用jQuery方法

谁能帮忙?
