我在 asp.net 和 c#.net 中使用带有文本框的 ajax 自动完成扩展器。我无法获得可供选择的列表，我有适当的 Web 服务方法调用..任何人都可以指导我完成自动操作。
<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<div>
<asp:AutoCompleteExtender runat="server" ID="autoComplete1" TargetControlID="TextBox1"
ServiceMethod="GetCompletionList"
ServicePath="AutoComplete.asmx"
MinimumPrefixLength="0"
CompletionInterval="50"
EnableCaching="true"
CompletionSetCount="1"
DelimiterCharacters=";, :"
ShowOnlyCurrentWordInCompletionListItem="true">
</asp:AutoCompleteExtender>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
</form>
并且网络服务方法包含以下代码
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[ScriptService]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class AutoComplete : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
[WebMethod]
public string[] GetCompletionList(string prefixText, int count)
{
List<string> responses = new List<string>();
for (int i = 0; i < count; i++)
responses.Add(prefixText + (char)(i + 65));
return responses.ToArray();
}
}
