我想调用jQuery自动完成功能,但单击按钮后。在按钮单击事件中,GridView和Textbox可见,否则它们是看不见的。
以下是我的代码脚本
$(document).ready(function () {
SearchText();
});
function SearchText()
{
$(".autosuggest").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CalendarDetails.aspx/GetAutoCompleteData",
data: "{'Col3':'" + document.getElementById('txtSearch').value + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
});
}
});
}

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;
}
问题是在按钮单击事件AutoComplete(jQuery)搜索操作不起作用。请帮助我问题所在。我错了
查看您的代码,看起来您的搜索文本框在更新面板外面。因此,以下代码应起作用:
$(document).ready(function () {
$(".autosuggest").autocomplete({
source: function (request, response) {
var col3 = $("#txtSearch").val();
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CalendarDetails.aspx/GetAutoCompleteData",
data: { Col3: JSON.stringify(col3) },
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
});
},
});
});
如果搜索文本框在更新面板内部,则将通过AJAX加载,您必须将jQuery事件绑定到更新面板上方的DOM元素。
更新面板包裹在DIV中:
<div id="someDivOutsideUpdatePanel">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" >
<input type="text" id="txtSearch" class="autosuggest" />
</asp:UpdatePanel>
</div>
将事件绑定到DIV:
$(document).ready(function () {
$("#someDivOutsideUpdatePanel .autosuggest").autocomplete({
// Same code as above
});
});
