1.前台代码:

 <style type="text/css">
 
  .backgroudcolor
  {
   background-color:#D6FAF9;
  }
  .onmouservoer
  {
    background-color:#E9EDAF;

         ServicePath="testwebservers.asmx" ServiceMethod="GetHotSearchBywords" MinimumPrefixLength="1" CompletionInterval="500"
          EnableCaching="true" CompletionSetCount="10"  CompletionListItemCssClass="backgroudcolor"  CompletionListHighlightedItemCssClass="onmouservoer">
        </cc1:autocompleteextender>
        </div>

2.后台代码:

webserver:

  [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.
    [System.Web.Script.Services.ScriptService]
    public class testwebservers : System.Web.Services.WebService
    {

        [WebMethod]

        public string[] GetHotSearchBywords(string prefixText,int count)
        {
            return BookManager.GetBookKeywords(prefixText,count);
        }

    }

 

bll 省略...

dal:

 public static string[] GetBookKeywords(string keyword,int displaycount)
      {
          IList<Book> book = new List<Book>();
          List<string> result = new List<string>(displaycount);

          string sql = "select top 10 * from Book where title like '%" + keyword + "%' order by id";

          book =getALLBookBysql(sql);

          foreach (Book item in book)
          {
              result.Add(item.Title);

          }          return result.ToArray();      }
