See above link. I use css to hide the default text and use a label to show what I want:

html

<div>
      <input type='file' title="Choose a video please" id="aa" onchange="pressed()">
      <label id="fileLabel">Choose file</label>
</div>

css

input[type=file]{
    width:90px;
    color:transparent;
}

javascript

window.pressed = function(){
    var a = document.getElementById('aa');
    if(a.value == "")
    {
        fileLabel.innerHTML = "Choose file";
    }
    else
    {
        var theSplit = a.value.split('\\');
        fileLabel.innerHTML = theSplit[theSplit.length-1];
    }
 };

Answer 2

You replace the text with your own message using CSS pseduo-class :after. You can declare a class like this one:

.bar:after {
    content:"Please select a file";
    background-color:white;
}

And assign it to your FileUpload control. The content message will replace the original one. Of course upon file selection you need to remove the message, you can do this for example via jQuery .removeClass (assuming ID of your FileUpload is "foo"):

$('#foo').change(function() {
    $(this).removeClass("bar");
})

Note that this solution seems to work Webkit-browser's only (Chrome, Opera, Safari) you may need an alternative for others.
