我正在處理一個項目,該項目需要在輸入某些數據時自動完成文本框,並且將從數據庫中提取數據。自動完成Jquery函數在調用webservice時返回內部服務器錯誤
爲此,我創建了一個Web服務作爲 -
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
//[ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[ScriptService]
public class SearchIssues : System.Web.Services.WebService
{
//[ScriptMethod]
[WebMethod]
public string[] GetCompletionList(string prefixText)
{
DataSet ds = null;
DataTable dt = null;
OracleConnection conn = null;
StringBuilder sb = new StringBuilder();
try
{
conn = new OracleConnection(WebConfigurationManager.ConnectionStrings["Conn"].ToString());
sb.Append("select issueno from cet_sepcet where issueno like '");
sb.Append(prefixText);
sb.Append("%'");
OracleDataAdapter daRes = new OracleDataAdapter(sb.ToString(), conn);
ds = new DataSet();
daRes.Fill(ds);
dt = ds.Tables[0];
}
catch (Exception exc)
{
}
if (conn.State == ConnectionState.Open)
{
conn.Close();
}
List<string> IssueList = new List<string>();
for (int i = 0; i < dt.DataSet.Tables[0].Rows.Count; i++)
{
IssueList.Add(dt.DataSet.Tables[0].Rows[i][0].ToString());
}
return IssueList.ToArray();
}
}
我寫了jQuery AJAX方法是 -
$(function() {
$(".tb").autocomplete({
source: function(request, response) {
debugger;
$.ajax({
url: "SearchIssues.asmx/GetCompletionList",
data: request.term,
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function(data) { return data; },
success: function(data) {
response($.map(data.d, function(item) {
return {
value: item
}
}))
//alert('Hello');
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
debugger;
alert(errorThrown);
}
});
},
minLength: 1
});
});
WebService的運行完全正常。但是當我嘗試從.aspx頁面調用webservice時,問題就出現了。它的引發內部服務器錯誤。
我不知道我哪裏出錯了。請幫助。
在此先感謝。 Akhil
