I've stumbled across some code that works in Firefox but not Chrome.
What seems to be happening is that there is a file upload textfield that is sized in CSS. There is also an Upload button immediately to its right for the user to click to open a dialog to select a file. The textfield length is 60, which I think is used to overlay the "Upload" button and not size the field. I've reduced 60 to 50 in Firebug and it stops working.
How can I invoke the file upload dialog from the Upload button? I think I need to send some sort of click event to the textfield.
File: __________________ Upload | Clicking field or Button opens file dialog
I've extracted the HTML:
<input name="fileField" id="fileField" type="file" size="60"> <span><input type="text" id="fileUploadField"><span></span></span> <a href="javascript://" class="button" id="uploadButton"><span class="action">Upload</span></a>
The following should work for you:
document.getElementById('uploadButton').addEventListener('click', function(){
document.getElementById('fileField').click();
return false;
}, false);
