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

EnableCaching="true" CompletionSetCount="10" CompletionListItemCssClass="backgroudcolor" CompletionListHighlightedItemCssClass="onmouservoer">

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();
}
