jquery / Javascript - initiating file input to get around IE bug

I have a file button (for uploading an image).
I want to use an image to fire the 'file' selection. I have crated an image in a <label> tag and used 'for' to enable the <label> (and therefor the image) to fire the 'file' dialogue.

<label for = "userfile" style = "cursor: hand;cursor: pointer;">
	<input style = "display:none;" name="userfile" id="userfile" type="file" />
	<img src="<%=v_image%>">
</label>

Open in new window


The example shows my test code (apologies for the inline styling).

However there is a bug in IE that stops this working when you put the code inside a <form> tag. So firing manually using javascript/Jquery would seem to be a solution.

From my research there seems to be limitation with some browsers stopping the programmatic firing of a 'file' input, as this is deemed a potential security risk.

Does anyone have a solution that will allow me to get round this and allow the firing of a 'file' input when an image is clicked that will be cross browser compatible?

Take a look at the many AJAX file uploaders.

They use an iframe to do exactly this.

How about something like this:
<input type="file" id="userfile" name="userfile" style="visibility: hidden; width: 1px; height: 1px" >
<a href="" onclick="document.getElementById('userfile').click(); return false"><img src="your-image"</a>

how about something like this-

>> css

#upload_wrap {position:absolute; top:25px; left:25px; width:332px; height:30px; cursor:pointer;}
#file_input {position:absolute; top:10px; left:10px; width:0px; height:0px; overflow:hidden; z-index:0;}
#browse_btn {position:absolute; top:0px; left:0px; width:60px; height:30px; background-color:#CCC; border:thin solid #333; text-align:center; z-index:1;}
#sel_name {position:absolute; top:0px; left:62px; width:300px; height:14px; border:thin solid #333; padding:8px; z-index:1;}

>>html


<div id="upload_wrap" onClick="document.getElementById('fi').click();">
    <div id="file_input">
          <input id="fi" type="file" onChange="document.getElementById('sel_name').innerHTML = this.value;"/><input />
    </div>
    <div id="browse_btn">Browse</div>    
    <div id="sel_name"></div>
</div>


***just dump it into your upload form
** could use some work - i spent about 5 mins on it -
FYI should be 100% cross browser
