Hi!

I am wokring on an enterprise appln using jsp, struts and servlets.

I have a dropdown in my jsp page. This has three values: Intranet, Extreanet and Internet.I want to get the value of the dropdown, when the user selects something fro the dropdown.

I tried using the follwoing code:

This returns something like this:
http://prodinfoadmin-acc.ericsson.se?channel=1&.....

The "1" in the url indicates that it is "Intranet". How do i extranct this value?

Any ideas?

This gets the elements from two dropdowns, and compare the values:

alert("1");
var indexvaluedog1 = document.sikkerhedForm.dogs.selectedIndex; 
alert("2");
var valuedog1 = document.sikkerhedForm.dogs[indexvaluedog1].text;
alert("3");

var indexvaluedog2 = document.sikkerhedForm.dogs1.selectedIndex; 
alert("4");
var valuedog2 = document.sikkerhedForm.dogs1[indexvaluedog2].text;
alert("5");
 
theItemClass = document.getElementById(xItem); 
 
if (valuedog1!=valuedog2) {
     theItemClass.className = "goShow";
 
}
else {
   theItemClass.className = "noShow";
 
}
     
  }

</script> 
 
</head>
 
<BODY>
 
<form name="sikkerhedForm" method="post">
 
<select name="dogs" onchange='ShowHideItem("showTable")'>
   <option>Domestic Dog</option>
  <option>Arctic Fox</option> 
 <option>Maned Wolf</option>
  <option>Grey Wolf</option> 
 <option>Red Fox</option>
  <option>Fennec</option> 
</select>
 
<select name="dogs1" >
   <option>Domestic Dog</option>
  <option>Arctic Fox</option> 
 <option>Maned Wolf</option>
  <option>Grey Wolf</option> 
 <option>Red Fox</option>
  <option>Fennec</option> 
</select>
