For Firefox. Because of security it has a truncated path. However, they have provided other ways of doing this:
var img = document.createElement("IMG");
if(document.all)
img.src = document.getElementById('submit').value;
else
// Your solution for Firefox.
img.src = document.getElementById('submit').files.item(0).getAsDataURL();
document.getElementById('div').appendChild(img);
The below is working in Internet Explorer 7 and Firefox 3.
<style type="text/css">
#prevImage {
border: 8px solid #ccc;
width: 300px;
height: 200px;
}
</style>
<script type="text/javascript">
function setImage(file) {
if(document.all)
document.getElementById('prevImage').src = file.value;
else
document.getElementById('prevImage').src = file.files.item(0).getAsDataURL();
if(document.getElementById('prevImage').src.length > 0)
document.getElementById('prevImage').style.display = 'block';
}
</script>
<pre>
IE8 needs a security settings change: internet settings, security, custom level :
[] Include local directory path when uploading files to a server
( ) Disable
(o) Enable
</pre>
<form>
<input type="file" name="myImage" onchange="setImage(this);" />
</form>
<img id="prevImage" style="display:none;" />
