快疯了!调试了很久还是不行!!
请各位大侠帮帮看一下!aspx内容:

}代码很简单,就是用js脚本调用后代getServerValue函数!!可是用"alert(PageMethods.getServerValue(onSucess()))"测试返回的内容的是一只是undefined,不知道该怎么修改!!!!万分感谢!!

function test()
{
//onSucess()的括号要去掉
//PageMethods.getServerValue(onSucess());
PageMethods.getServerValue(onSucess); } function onSucess(result)
{
alert(result);
} </script>
可是用"alert(PageMethods.getServerValue(onSucess()))"测试返回的内容的是一只是undefined,不知道该怎么修改!!!!
--直接alert()它是返回undefined的,因为结果还没返回,异步的,回调onSucess是调用完触发的,所以在onSucess里可以正常alert(result)
PageMethods.getServerValue(id,ischecked,check_CheckedChanged_Success,check_CheckedChanged_Failed);
必须有失败与成功的处理函数,你的js 没有写完整,缺少这两个函数,lz 结贴给分吧
// 调用页面后台方法,前面跟方法所需的参数,接着是方法回调成功时要执行的js函数,最后一个是方法回调失败时要执行的js函数
PageMethods.sss('ss',funReady,funError);
}
// result 就是后台方法返回的数据
function funReady(result){
// div1.innerHTML=result;
alert(result);
//alert(div1.innerHTML);
}
// err 就是后台方法返回的错误信息
function funError(err){
alert("Error:" + err._message );
}
function iniCooke()
{
//document.cookie="id=12";;
}
function readyCooke()
{
//var s=document.cookie;
//div1.innerHTML=s;
}
在FF下面可以运行 在IE里面不能运行
