用在JavaScript的RequestHelper
RequestHelper.js
//功能 : 在javascript中提供QueryString/Cookie/Anchor的访问.
/*使用 :
var Request = new RequestHelper();
var s = Request.QueryString["id"]; //取得url中的id参数.
var c = Request.Cookies["name"]; //取得id为name的cookie值.
var a = Request.Anchor; //取得url中定位的锚点名称.
*/
//更新 : 2008-05-31
RequestHelper.prototype.GetParams = function()
{
var result = {};
var loc = document.location.toString();
if(loc.indexOf("?") > -1)
{
var l = loc.lastIndexOf("#") > -1 ? loc.lastIndexOf("#") : loc.length;
var param_str = loc.substring(loc.indexOf("?")+1, l);
var params = param_str.split("&");
for(var x = 0; x < params.length; x++)
{
params[x] = params[x].split("=");
result[params[x][0]] = params[x][1];
}
}
return result;
}
RequestHelper.prototype.GetCookies = function()
{
var result = {};
var cookie = document.cookie;
if(cookie.length > 0)
{
var reg = /(^[a-zA-z0-9]+?|; [a-zA-z0-9]+?)=/g;
var c = cookie.match(reg);
if(c)
{
var n = 0;
for(var x = 0; x < c.length; x++)
{
n = (x < c.length - 1) ? cookie.indexOf(c[x + 1].toString()) : cookie.length;
var s = cookie.substring(cookie.indexOf(c[x].toString()),n);
s = s.split("=");
s[0] = s[0].replace(/^; / , "");
result[s[0]] = s[1];
}
}
}
return result;
}
RequestHelper.prototype.GetAnchor = function()
{
var Anchor;
var loc = document.location.toString()
if(loc.lastIndexOf("#") > -1)
{
Anchor = loc.substring(loc.lastIndexOf("#")+1);
}
return Anchor;
}
function RequestHelper()
{
this.QueryString = this.GetParams();
this.Cookies = this.GetCookies();
this.Anchor = this.GetAnchor();
}
经初步测试,没发现问题,但不保证没有任何bug,有用得上的,请随便复制粘贴,有更好的方法的,请各位多多指点,我只是小菜一个,大家就砖下留情了.
另,因cookie的名称不支持某些特殊符号,所以这里只取了数字和字母,大家注意了,如果有其它的办法,麻烦指点指点。呵呵!
