用ICallbackEventHandler接口 实现无刷新回传
成功代码:
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "testClientCallBack.aspx.cs " Inherits= "testClientCallBack " %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN " "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<script type= "text/javascript ">
function CallServer()
{
var product = "test ";
<%= ClientScript.GetCallbackEventReference(this, "product ", "ReceiveServerData ",null)%> ;
}
function ReceiveServerData(rValue)
{
//alert(rValue[0]+ '/ '+rValue[1]+ '/ '+rValue[2]+ '/ ');
alert(rValue);
}
</script>
<html xmlns= "http://www.w3.org/1999/xhtml " >
<head runat= "server ">
<title> 无标题页 </title>
</head>
<body>
<form id= "form1 " runat= "server ">
<div>
<button onclick= "CallServer() "> CallServer </button>
</div>
</form>
</body>
</html>
----------------------
private string CallBackValue = string.Empty;
string ICallbackEventHandler.GetCallbackResult()
{
string a1 = "test ";
return CallBackValue + ",ok ";
// return a1;
}
void ICallbackEventHandler.RaiseCallbackEvent(string eventArgument)
{
this.CallBackValue = eventArgument;
}
现在想返回一个数组
string[] ICallbackEventHandler.GetCallbackResult()
{
string[] a1 = new string[]{ "a ", "b ", "c "};
&nb
