How to apply FileField Button click in FF?

I have this html code :

    <form name="form1" id="form1" method="POST" action="">

    <div dir="rtl" style="position:absolute; left: 2px; top: 0px;">
       <input name="fileField2" type="file" class="accountItemFilefield" id="fileField2" />
    </div>
    <div style="position:absolute; z-index:2;">
         <img onclick="$('#fileField2').trigger('click'); " style="cursor:pointer" src="images/browse.png" width="83" height="29" alt="" />
  开发者_开发问答 </div>

    </form>

This code is not working in FF and it's working successfully in IE and I don't know what is the problem.

I also tried this code :

$('#fileField2').click(); 

and this one :

document.getElementById('fileField2').click(); 

all of them are working in IE bur not in FF.

How I can solve the problem?

Thanks in advance.

This is a security restriction to prevent malicious sites from unexpectedly showing the file upload dialog.

I don't think there is a way around this. In fact, I'm surprised that IE still allows it.

document.getElementById('fileField2').click(); worked when I tried it. (I didn't try the other versions.)

The only security restriction applies if you try to launch the filepicker at a time when a popup would be blocked, in which case you get the regular blocked popup notification.
