    Javascript in different browsers

    right, I'm trying to make a battle system, which already works, but now i added a HP bar (with some help from xDev ) and it works fine for me in IE, but for example Opera doesn't get it right..

    IE, good version :


    Opera, wrong :

    here's the whole code (offcourse you can also view the source )
    HTML Code:
    <HTML>
<HEAD>	
<style type="text/css">
#balk 
{
  width: 100px;
}
</style>
<script language="JavaScript">
		
var lvl = 10;
var att = 34;
var edef = 40;
var widthBalk = 100;
var widthLeeg = 0;
					
function attack(type)
{
	if(type=='norm')
		{
			var dmg=Math.round((((2*lvl/5+2)*(att/2)*(5 + Math.random()*10)/edef)/5+2));
			if(dmg < "1" ){ dmg = "1"; } 
			schade.innerHTML = dmg;
			hp.innerHTML -= dmg;
						
			// start HP balk
			widthBalk = hp.innerHTML;
			widthLeeg = 100 - hp.innerHTML;
			
			if(widthLeeg >= 100)
			{
				hp.innerHTML = 0;
				document.getElementById("balk").style.width = 0;
				document.getElementById("leeg").style.width = 100;
			}
			else
			{
				document.getElementById("balk").style.width = widthBalk;
				document.getElementById("leeg").style.width = widthLeeg;
			}		
			
			// einde HP balk
			
			
			
		
		}
					
	if(type=='fb')
		{
			if(mpx.innerHTML < 1)
			{ 
				alert("Your can't use FireBall any more\nbecause your MP is too low");
			}
			else
			{
				var dmg=Math.round((((2*lvl/5+2)*(att/2)*(30 + Math.random()*40)/edef)/5+2)); 
				if(dmg == "0" ){ dmg = "1"; } 
				mpx.innerHTML = mpx.innerHTML - 5;
				schade.innerHTML = dmg;
				hp.innerHTML -= dmg;
				
				// start HP balk
				widthBalk = hp.innerHTML;
				widthLeeg = 100 - hp.innerHTML;
			
				if(widthLeeg >= 100)
				{
					hp.innerHTML = 0;
					document.getElementById("balk").style.width = 0;
					document.getElementById("leeg").style.width = 100;
				}
				else
				{
					document.getElementById("balk").style.width = widthBalk;
					document.getElementById("leeg").style.width = widthLeeg;
				}		
			
			// einde HP balk
				
			}
		
	    }
					
	if(hp.innerHTML < 1)
		{
			hp.innerHTML = "0";
			var text = 
			"You Destroyed The Enemy!\nCongratulations!\n\n" +
			"This gave you 20 experience points!";
			alert(text);
		}

    Hi XzAzX,

    I've looked at this several times, and finally dug into it a little deeper.

    Opera7 is reacting strangely, I agree. When the TDs are resized td.offsetWidth does not change by the same amount td.style.width changes - but padding and border width remain constant.

    There are several tips I would like to give about your code - but I don't have time right now, sorry.

    For another way of implementing a bar-graph, have a look at this: xBarGraph demo.
