错误： uncaught exception 是什么错误？

[多菜鸟]

错误： uncaught exception: [Exception... "Component returned failure code: 0x805e000a [nsIXMLHttpRequest.open]" nsresult: "0x805e000a (<unknown>)" location: "JS frame :: http://192.168.1.75/js/ajax.js :: GetResult :: line 15" data: no]


ajax.js
===============
// JavaScript Document
function GetResult(url){
var showmov = null;
if(window.XMLHttpRequest){ //IE7, Mozilla ,Firefox 等浏览器内置该对象

showmov = new XMLHttpRequest();

}else if(window.ActiveXObject){ //IE6、IE5

try{ showmov = new ActiveXObject("Msxml2.XMLHTTP");} catch (e){ ; }

if( showmov == null) try { showmov = new ActiveXObject("Microsoft.XMLHTTP");} catch (e){; }

}
showmov.open("post",url,false);
showmov.send(null);
if(showmov.readyState == 4) {
if(showmov.status == 200) {
var strResult = showmov.responseText;
}
}
showowmov = null
return strResult;
}

showmov.open("post",url,false);
showmov.send(null);
if(showmov.readyState == 4) {
if(showmov.status == 200) {
var strResult = showmov.responseText;
}
}
showowmov = null
return strResult;

这一段修改成
showmov.open("post",url,false);
showmov.send(null);
var strResult = "";
if(showmov.readyState == 4) {
if(showmov.status == 200) {
strResult = showmov.responseText;
}
}
showowmov = null
return strResult;
可能你的两个if没有执行,这样就不能生成strResult这个对象的吧

if(showmov.readyState == 4) {
if(showmov.status == 200) {
strResult = showmov.responseText;
}
}
showowmov = null
return strResult;
}

修改成这样子之后还是错误，还会有其它的原因吗？？

错误在火狐里的错误控制台里发现的。。

[chuckcoin]

未捕获的异常

推测可能是由于strResult未定义引起的

[多菜鸟]

没有人帮我看一看吗？？

我也发现有这问题, 怎么解决啊?

AJAX中的 uncaught exception: ...
这是因为firefox安全性强，不允许跨域调用。 Firefox 要取消XMLHttpRequest的跨域限制的话，第一是从 about:config 里设置 signed.applets.codebase_principal_support = true； （地址栏输入about:config 即可进行firefox设置）第二就是在open的代码函数前加入类似如下的代码： try { netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead"); } catch (e) { alert("Permission UniversalBrowserRead denied."); } 第三，就是URL的地址不正确，错写成127.0.0.1。。。了

搭车问 如何卸载掉megaupload上传文件插件



错误： uncaught exception: [Exception...

禁用AdBlock试试看，应该是冲突了

[young00001]

我也是用火狐浏览器的firebug调试页面出现一堆错误 首先就是
uncaught exception: [Exception... "prompt aborted by user" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: resource://gre/components/nsPrompter.js :: openTabPrompt :: line 468" data: no]

Line 0

然后是说一堆JS文件的第一行未组织好

求解。。。
