目的：让浏览器每隔15秒自动Google搜索一下“胡萝卜”三字并在.com和.com.hk之间互换。

现象：出现连接被重置，整个IP会被暂停Google搜索。

后果：页面一直开着可能会导致整个公司不能使用正常的Google搜索（翻墙或使用HTTPS除外）。

应用：给那些认为GFW对他们没有影响的人予亲身体验。

代码：

<script language=”javascript” type=”text/javascript”>
var m_switchUrl = false;
function checkGoogleBlock() {
var _url = null;

if (m_switchUrl) {
_url = “http://www.google.com.hk/search”;
m_switchUrl = false;
} else {
_url = “http://www.google.com/search”;
m_switchUrl = true;
}
var _frm = newForm(_url);

addParam(_frm, “hl”, “zh-CN”);
addParam(_frm, “source”, “hp”);
addParam(_frm, “q”, “胡萝卜”);
addParam(_frm, “aq”, “f”);
_frm.submit();
releaseForm(_frm);
}

function newForm(pUrl) {
var _frmObj = document.createElement(“form”);

_frmObj.method = “get”;
_frmObj.action = pUrl;
_frmObj.target = “_checkGoogleBlock”;
document.body.appendChild(_frmObj);

return _frmObj;
}

function releaseForm(pForm) {
document.body.removeChild(pForm);
}

function addParam(pForm, pName, pValue) {
var _obj = document.createElement(“input”);

_obj.type = “hidden”;
_obj.name = pName;
_obj.value = pValue;
pForm.appendChild(_obj);
}

checkGoogleBlock();
setInterval(“checkGoogleBlock()”, 15000);
</script>

测试：链接

解决办法：关掉那个打开的页面或者参考链接1，链接2

PS. 有些浏览器会把这种自动弹出窗体的行为禁掉，改成允许该网站的弹出窗体即可。
