bug with increasing the size of image

10-18-2009 7:36 PM |

Hello every body!

I have the two next listings:

This example DOESN'T WORK!

1    <script>
2    
3    function oleg()
4    {
5    	var a = document;
6    	
7    	var b = a.pic1.width;
8    	
9    	if( b == 200 )
10   	{
11   		a.pic1.width = b + 20;
12   		setTimeout("oleg();", 5);
13   		
14   		if(b == 500)
15   		{
16   			a.pic1.width = b;
17   		}
18   	}
19   }
20   
21   </script>
22   
23   <img src ="./1.jpg" width ="200" name ="pic1" onMouseOver ="oleg();">

And, if I shall change in line:9 from "if( b == 200 )" to "if( b > 0 )"
the effect will work!

I want to know, why it doesn't work?

I set at <img> the value of width: 200px.

And in the script logic, I check if ( b == 200) and you can see that the variable `b` equals 200 at <img> indeed.

Why the version with b = 200 doesn't work and if I change it to b < 0 , the effect will work?

Can somebody help me?

Best Regards,

Oleg

I'm not sure why its not working with you. I copied your code and its working fine with me.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>

    <script>

        function oleg() {
            var a = document;

            var b = a.pic1.width;

            if (b == 200) {
                a.pic1.width = b + 20;
                setTimeout("oleg();", 5);

                if (b == 500) {
                    a.pic1.width = b;
                }
            }
        }
   
    </script>

</head>
<body>
    <img src="score.bmp" width="200px" name="pic1" onmouseover="oleg();" />
</body>
</html>

If I put if(b == 200), it increases the img width once to 220 and in the next run it stops increasing the width as it finds b=220. If you wanna let the image width grow as long as the mouse is over the image and until it is 500, try putting if(b>=200) instead.

Hope this helps.

How is this Silverlight related?

I'm training to support Moonlight Smile , the part of Silverlight, but on GNU\Linux.
Becuase Moonlight works fine only with 1st version of Silverlight, which was XAML + JavaScript.
