I have a pull down to list countries on my form. When the user selects a country, it refreshes the page by calling the backend (Java) code (This is primarily done to update a bean). When the page returns the focus on the country field is lost. In order to fix this, I placed a <a name> tag in the html right before the country tag and call the javascript function below:

function setCountryFocus(){
document.forms[0].addrCountryCode.focus();
}

Problem: If I keep hitting the countries starting with "F", sometimes the focus goes to the BROWER's FILE->NEW. If it starts with "V" it goes to BROWSER's ->VIEW.

Can someone help me with this. Need to fix this bug asap.

Thanks!!

You want to maintain the position on the page.

try this:

<html>
 <head>
 <title>Fun Scroll</title>
 <script type="text/javascript">
 window.onload = function(){
 var strCook = document.cookie;
 if(strCook.indexOf("!~")!=0){
 var intS = strCook.indexOf("!~");
 var intE = strCook.indexOf("~!");
 var strPos = strCook.substring(intS+2,intE);
 document.body.scrollTop = strPos;
 }
 }
 function SetScrollPosition(){
 var intY = document.body.scrollTop;
 document.title = intY;
 document.cookie = "yPos=!~" + intY + "~!";
 }
 window.onscroll = SetScrollPosition;
 </script>
 </head>
 <body>

Deepa, if nothing on the page changes, and the reload is simply to update a bean on the server, why reload the page at all? You can send a request to the server through either an XMLHttpRequest object or a simple hidden iframe. Then you don't need to worry about the focus.
