什么样的网址路径可以满足这个JS函数

<script type="text/javascript">
var url = "http://wap.blueidea.com/";
var bForcepc = fGetQuery("dv") == "pc";    
function fBrowserRedirect(){   
        
    var sUserAgent = navigator.userAgent.toLowerCase();    
    var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";      
    var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";    
    var bIsMidp = sUserAgent.match(/midp/i) == "midp";    
    var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";    
    var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";    
    var bIsAndroid = sUserAgent.match(/android/i) == "android";    
    var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";    
    var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";   

if(bIsUc || bIsUc7){
alert("对不起UC浏览器对HTML5支持不佳，请能使用Safari 或 Chrome!");
}

if(bIsIphoneOs){    
            var sUrl = location.href;        
            if(!bForcepc){    
                window.location.href = url;    
            }
        }
        
if(bIsAndroid){    
            var sUrl = location.href;        
            if(!bForcepc){    
                window.location.href = url;    
            }
        }if(bIsWM){     
 
            var sUrl = location.href;        
            if(!bForcepc){    
                window.location.href = url;    
            }
        }  } 
function fGetQuery(name){//获取参数值    
    var sUrl = window.location.search.substr(1);    
    var r = sUrl.match(new RegExp("(^|&)" + name + "=([^&]*)(&|$)"));    
    return (r == null ? null : unescape(r[2]));    
}    
function fShowVerBlock(){       
    if(bForcepc){    
        document.getElementById("dv_block").style.display = "block";    
    }    
    else{    
        document.getElementById("ad_block").style.display = "block";    
    }    
}      

fBrowserRedirect(); 
</script>

function fGetQuery(name){//获取参数值
var sUrl = window.location.search.substr(1);
var r = sUrl.match(new RegExp("(^|&)" + name + "=([^&]*)(&|$)"));
return (r == null ? null : unescape(r[2]));
}
这个函数是什么意思啊，var bForcepc = fGetQuery("dv") == "pc"; 什么样的网址可以满足这个条件啊
[解决办法]
xxxxxx?xxx&dv=pc
只要在url参数中有dv=pc 就可以
