帮帮忙看看，我用ARCGIS SERVER提供的AJAX老是提醒JS缺少对象
因为初次接触，我学习后，自己编写，有问题，我又照着书编了一次，还是有问题，并且是相同问题，JS缺少对象。。。我缺少不知道错在哪？谢谢，帮忙看看
function searchpostion()
{
var strname=document .getElementById ("provice").value;

message =strname ;

--------------------编程问答-------------------- message =strname;
可能是因为这个strname是在searchpostion()方法里面定义的局部变量，把它放到外面试一下
var strname=document.getElementById ("provice").value;
function searchpostion()
{
--------------------编程问答-------------------- js对象不存在， --------------------编程问答-------------------- 没有成功，我又将那段JS代码放进了HTML中，结果又可以了，不知道为什么。但是新的问题又出现了，不能实现异步刷新，。。。 --------------------编程问答-------------------- 1楼我用了你的方法，但是还是一样的问题。。。 --------------------编程问答-------------------- var strname=document .getElementById ("provice").value;
这行输出一下。。看有值没？ --------------------编程问答-------------------- 有值.我已经测试过了
补充：.NET技术 , ASP.NET
