function getVarsUrl(){
    var url= location.search.replace("?", "");
    var arrUrl = url.split("&");
    var urlObj={};   
    for(var i=0; i<arrUrl.length; i++){
        var x= arrUrl[i].split("=");
        urlObj[x[0]]=x[1]
    }
    return urlObj;
}

//Ej:http://www.misitio.com/index.html?var1=dato1&var2=dato2&var3=dato3

var misVariablesGet = getVarsUrl();
misVariablesGet.var1 // devuelve "dato1" y asi con los demas.
