将url的查询参数解析成字典对象

方法一：

function getQueryObject(url) {
    url = url == null ? window.location.href : url;
    var search = url.substring(url.lastIndexOf("?") + 1);
    var obj = {};
    var reg = /([^?&=]+)=([^?&=]*)/g;
    search.replace(reg, function (rs, $1, $2) {
        var name = decodeURIComponent($1);
        var val = decodeURIComponent($2);               
        val = String(val);
        obj[name] = val;
        return rs;
    });
    return obj;
}
 
getQueryObject("http://www.w3school.com.cn/tiy/t.asp?f=js_library_jquery");


//Object {f: "js_library_jquery"}

方法二：

function GetRequest(url) { 
    url = url == null ? window.location.href : url;//获取url中"?"符后的字串
    var theRequest = new Object(); 
    if (url.indexOf("?") != -1) { 
        var str = url.substr(1); 
        strs = str.split("&"); 
        for(var i = 0; i < strs.length; i ++) { 
            theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]); 
        } 
    } 
    return theRequest; 
} 

GetRequest("http://www.w3school.com.cn/tiy/t.asp?f=js_library_jquery");


//Object {ttp://www.w3school.com.cn/tiy/t.asp?f: "js_library_jquery"}
