how to show alternate image if source image is not found? (onerror working in IE but not in mozilla)

Question

Hi

I need to show an alternate image in cell of table if source image is not found. Currently below code is used to do so.

cell.innerHTML="<img height=40 width=40 src='<%=request.getContextPath()%>/writeImage.htm' onError='ImgErrorVideo(this);'>" 
function ImgErrorVideo(source){
        source.src = "video.png";
        source.onerror = ""; 
        return true; 
}

Now the problem is that the above is solution is working in Internet Explorer but not in mozilla.

Please tell me some solution which works in all browsers.

Thanks Jyoti

Answer 1

If you're open to a PHP solution:

<td><img src='<?PHP
  $path1 = "path/to/your/image.jpg";
  $path2 = "alternate/path/to/another/image.jpg";

  echo file_exists($path1) ? $path1 : $path2; 
  ?>' alt='' />
</td>

////EDIT OK, here's a JS version:

<table><tr>
<td><img src='' id='myImage' /></td>
</tr></table>

<script type='text/javascript'>
  document.getElementById('myImage').src = "newImage.png";

  document.getElementById('myImage').onload = function() { 
    alert("done"); 
  }

  document.getElementById('myImage').onerror = function() { 
    alert("Inserting alternate");
    document.getElementById('myImage').src = "alternate.png"; 
  }
</script>

Hi

I have got the solution for my query:

i have done something like this:

cell.innerHTML="<img height=40 width=40 alt='' src='<%=request.getContextPath()%>/writeImage.htm?' onerror='onImgError(this);' onLoad='setDefaultImage(this);'>"

function setDefaultImage(source){
        var badImg = new Image();
        badImg.src = "video.png";
        var cpyImg = new Image();
        cpyImg.src = source.src;

        if(!cpyImg.width)
        {
            source.src = badImg.src;
        }

    }


    function onImgError(source){
        source.src = "video.png";
        source.onerror = ""; 
        return true; 
    } 

This way its working in all browers.
