You need to get the parameters from the page url and use them on the page itself (substitute them in the href)

function getU(){var u=window.location.search,a=[],v=[],r=[];a=(u.substr(1)).split('&');if(a[0]=="")return!1;for(i=0;i<a.length;i ++){v=a[i].split('=');r[v[0]]=v[1]}
return r}
var res= getU();
alert(res['someparam']);
