javascript - Redirect page and auto-open some lightbox -

-

i have address: www.example.com/teste123

on page have redirect:

<% response.redirect "http://www.example.com/index.asp?teste=true" %>

so want? want if user access these address www.example.com/teste123, , page redirect root of website, open lightbox file inside...

i found script variable on url:

function geturlvars(){     var vars = [], hash;     var hashes = window.location.href.slice(window.location.href.indexof('?') + 1).split('&');     for(var = 0; < hashes.length; i++)     {         hash = hashes[i].split('=');         vars.push(hash[0]);         vars[hash[0]] = hash[1];     }     return vars; }     var xxx = geturlvars()["teste"];

these return me true .. right... but.. how open lightbox if var xxx equal "true" ?

there lots of tutorials on lightboxes can google , pick from. basic logic (assuming you're using jquery):

<div class="my_light_box" style="display:none;">hi.</div>  <script> if(geturlvars()["test"]) {     $('.my_light_box').show(); }  function geturlvars(){     var vars = [], hash;     var hashes = window.location.href.slice(window.location.href.indexof('?') + 1).split('&');     for(var = 0; < hashes.length; i++)     {         hash = hashes[i].split('=');         vars.push(hash[0]);         vars[hash[0]] = hash[1];     }     return vars; }    </script>
