在項(xiàng)目制作中，有時(shí)候需要向用戶提供一定的幫助信息來(lái)提示用戶的操作，當(dāng)然，suggest功能是必不可少的，但是自己開發(fā)的話，是比較費(fèi)時(shí)費(fèi)事的，這里就直接拿JQuery的autocomplete來(lái)用吧，實(shí)驗(yàn)證明，效果很好

前臺(tái)代碼如下：

復(fù)制代碼代碼如下:

 
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

}); 
//請(qǐng)求完成，被回調(diào)的函數(shù) 
function rServer(arg, context) { 
eval(arg); 
$("#sugest").focus().autocomplete(data); 
} 
//向服務(wù)器端發(fā)起數(shù)據(jù)處理請(qǐng)求 
function raiseEvent(arg, context) 
{ 
<%=ClientScript.GetCallbackEventReference(this,"arg","rServer","context") %>; 
} 
</script> 
</head> 
<body> 
<form id="form1" runat="server"> 
<div> 
<input type="text" name="text" id="sugest" style="width:200px" /> 
</div> 
</form> 
</body> 
</html> 

然后就是后臺(tái)代碼，當(dāng)然了，這里只是模擬數(shù)據(jù)：

復(fù)制代碼代碼如下:

using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using System.Text;

} 
private StringBuilder GenStr() 
{ 
StringBuilder sbStr = new StringBuilder(); 
sbStr.Append("var data = "); 
sbStr.Append("["); 
sbStr.Append("\"Aback\",");

return GenStr().ToString(); 
}
