Clearing an Input Text

[SDyke]

I want the user to be able to click a button an clear the contents of an input box. The input box os of the type file and does not respond to the document.getElementById('myBox').value = "";

SDyke, unfortunately I have bad news for you. You can not dynamically change the value of an input of type file. This is because of security reasons. Imagine you are uploading an image to a server using an input of type file. And, right as you hit the submit button, javascript changes the input to point at a different file instead. You could be uploading potentially sensitive information to a webserver and not even know that it's happening...

As kaht said, you cannot change the value in the file input.
But I think you could clear the value with a reset method on the form or a reset button.
I haven't tried it myself but you can try it..

<form action="a_page.php" method="GET">
<input type="file" /><br />
<input type="reset" value="Clear form" />
</form>

Yes, however keep in mind that this will (obviously) reset all fields in your form, which is something that you may consider undesirable.

You could always do a quick round-up of all the current form values, plop them in an array, reset the form and repopulate the values from the array.

Yes I know. Or you could replace the input field with a new one. If you have many fields in the form this might be a good solution.
