I don't think that setting table cells (<td> elements) to be "display: block" is going to work out well in Firefox. Table cells have their own "display" type, and if you make them "display: block" the browser is going to do what you ask. Note that "display: block" is not simply the opposite of "display: none".

Try using "display: table-cell" instead of "block".

edit — I've tried this and it's definitely what the problem is.

Answer

Your problem in FF

document.home_page.uname is undefined
Line 27
Answer

The problems you have are

  • your TD is inheriting the height=200 from the TABLE
  • your TD has display: block which forces it onto a new line

Why are you using tables for this? They add a lot of extra, unnecessary tags. Have a read up on CSS, it's the future (and the present..)!

Answer

The most obvious thing to me is that you use self closing <LINK> and <META> tags in what is probably not a XHTML file. Those are meant to be left open. Try

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">  
<title>HOME</title>  
<link rel="stylesheet" href="dropdown.css" type="text/css" >  

instead.

IIRC Firefox does not read the link to your css file if the tag is self closing, because it is presumed empty.

Answer

Well there is a typo in the code

html += ....

should be

post += ....
Answer

This line: show.splice(index, 1);

should be: array.splice(index, 1);

You are removing one element from your array.

This line: function remove(index)

should be: function removeComment(index)

You are calling removeComment when you click the check box so your function needs to be called removeComment.

Answer

Just set .style.backgroundColor: http://jsfiddle.net/VvZZD/2/.

function showDetails(var1) {
   document.cubicle.employee.value=var1;

   var status = document.cubicle.status.value;
   var color;
   if(status == "0") color = 'yellow';
   if(status == "1") color = 'red';
   document.cubicle.employee.style.backgroundColor = color;
}
Answer

using jquery you can do like this:

  function changeStyle(val) {
       $('.employee').attr('value')=val;
        var pos = $('.employee').attr('value');
        var col = (pos=='0')? "yellow" : "red";
      $('.employee').css('color', col);
    }
Answer

You can make a javascript method where you can pass the status value either 1 or 0 and then use " document.bgColor "method to change the color using if conditions...

you can take help from here: http://www.javascripter.net/faq/backgrou.htm here dropdownlist value is selected... but you can use any control or hidden value...
