I was wondering, if it is possible to select 4th option from dropdown menu after redirect from other page and 5th option after redirect from another page.

<select>
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>

Answer 1

If it is simple html you can use:

HTML:

<div class="nu">
   <select>
     <option value="v1">Value 1</option>
     <option value="v2">Value 2</option>
     <option value="v3">Value 3</option>
   </select>
</div>

JQuery:

var url = service.getUrl();
if(url == 'www.google.com')
$("div.nu select").val("v2");

To get previous page url in js(Except IE):

<script type="text/javascript">
var ex=document.referrer;
document.write(ex);
</script>
