I want to change the default style of input file, I searched SO and find a solution. http://jsfiddle.net/younyzhU/6v8uL2co/
<div id=customOrth style="position: absolute; left:0; top:0px; ">
<button><label for="inputFile" style="padding-left: 0px;">
<a >choose orthology File</a></label></button>
<input style="display: none;" type="file" id="inputFile">
</div>
However when I select a file, I need to change the label to the selected file name, how should I do? The default input file, will show you the choosed file name, after select a file. thanks!
