//這個方法把ajax方法封裝一下，方便調用。
function myajax(){
//var obj=jsonData();

url:'ajax.aspx',

jsonStr+="\"123\"";

}
//調用前方法,不成功

}
//回呼函數

後台 複製代碼 代碼如下:protected void Page_Load(object sender, EventArgs e)
{
Hashtable ht = new Hashtable();
string name = Request.Params["name"].ToString();
string birth = Request.Params["birthday"].ToString();
if (!string.IsNullOrEmpty(name) && !string.IsNullOrEmpty(birth))
{
//Response.ContentType = "Application/json";
//Response.Write(CreareJson("this is ok!", 1, name, birth));
ht.Add("info", "成功了");
ht.Add("sta", "狀態");
ht.Add("name", name);
ht.Add("birth", birth);
Response.Write(CreateJsonParams(ht));
}
Response.End();
}
private string CreateJsonParams(Hashtable items)
{
string returnStr = "";
foreach(DictionaryEntry item in items)
{
returnStr += "\"" + item.Key.ToString() + "\":\"" + item.Value.ToString() + "\",";
}
return "{" + returnStr.Substring(0,returnStr.Length-1) + "}";
}
