url相关

js通过a标签解析url parseURL.js

/*
 * @function: 通过a标签解析url标签
 * @param:url  url参数是字符串，解析的目标
 通过IE6-9 chrome  Firefox测试
 *
 */
function parseURL(url) {
    //创建一个a标签

    var ac = arguments.callee;
    if(!ac.a) {
        ac.a =  document.createElement('a');
        ac.div = document.createElement('div');
    }
    var a =  ac.a;
    var div = ac.div;

    //将url赋值给标签的href属性。
    a.href = url;

    if((a.parentNode || a.parentNode) == div){
        div.removeChild(a);
    }

    div.appendChild(a);

    return {
        source: url,
        protocol: a.protocol.replace(':',''), //协议
        host: a.hostname,   //主机名称
        port: a.port,   //端口
        query: a.search,  //查询字符串
        params: (function(){  //查询参数
            var ret = {},
                    seg = a.search.replace(/^\?/,'').split('&'),
                    len = seg.length, i = 0, s;
            for (;i<len;i++) {
                if (!seg[i]) { continue; }
                s = seg[i].split('=');
                ret[s[0]] = s[1];
            }
            return ret;
        })(),
        file: (a.pathname.match(/\/([^\/?#]+)$/i) || [,''])[1], //文件名
        hash: a.hash.replace('#',''), //哈希参数
        path: a.pathname.replace(/^([^\/])/,'/$1'), //路径
        relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [,''])[1],  //相对路径
        segments: a.pathname.replace(/^\//,'').split('/'), //路径片段
        fullpath:a.href,
        href:a.href,
        toString:function(){
            return a.href;
        }
    };
}

urlParas解析params字符串为对象

var urlParas = function(url) {
    url = url||location.href;
    var urlObject = {};
    if (/\?/.test(url)) {
        var urlString = url.substring(url.indexOf("?")+1);
        var urlArray = urlString.split("&");
        for (var i=0, len=urlArray.length; i<len; i++) {
            var urlItem = urlArray[i];
            var item = urlItem.split("=");
            urlObject[item[0]] = item[1];
        }
    }
    return urlObject;
};

谢谢
