1.安装Firebug Lite
具体安装方法查看Firebug Lite的主页
http://getfirebug.com/lite.html
2.添加一段javascript到页面中
if (!window.console || !console.firebug)
{
var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",
"group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];
window.console = {};
for (var i = 0; i < names.length; ++i)
window.console[names[i]] = function() {}
}
或直接下载firebugx.js
http://getfirebug.com/firebug/firebugx.js
[Exception... "Component returned failure code: 0x805e000a
[nsIXMLHttpRequest.open]" nsresult: "0x805e000a (<unknown>)"
location: "JS frame :: http://localhost:8080/scripts/jquery.js ::
anonymous :: line 2699" data: no]
Exception提示是jquery获取不到结果.但浏览器直接访问地址可以得到结果
最终发现问题出现在firefox插件adblock上
因为我的servlet写成"/advertiser/page"
adblock把结果给过滤
因此jquery获取不到给出Component returned failure code: 0x805e000a
解决办法
把advertiser改名成vertiser,这样即使用户使用firefox和adblock也可以访问
