jQuery Stylefile

File input HTML controls are notorious because they are almost impossible to style by means of CSS. Each browser implements the file input in it's own way.

Stylefile is a jQuery widget that takes over the HTML file input control and allows it to be styled like the rest of the page. In addition, it gives the user more feedback on the selected file.

Dependencies

Stylefile is a simple jQuery control. It's only dependency is jQuery.

Usage

Load resources

At the end of the body part, load the jQuery library:

<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>

And the Stylefile code:

<script src="jquery.stylefile.js"></script>

Load from CDN

You may also load the Stylefile code from a content distribution network (CDN), like so:

<script src="https://unpkg.com/@sjaakp/stylefile/jquery.stylefile.min.js"></script>

Set-up

Stylefile is initialised like:

$(<selector>).stylefile(<options>);

Preferably, this is done in the document.ready handler, like:

<script>
    $(document).ready(function () {
        $("#fileInput").stylefile({
            ... Stylefile options ...
        });
    });
</script>

To select all file inputs on a page, use something like:

<script>
    $(document).ready(function () {
        $("[type=file]").stylefile({
			btnText: "Choose image to upload...",
            ... other Stylefile options ...
        });
    });
</script>

Options

btnClass

The classname(s) of the 'Browse' button. Default is: "btn btn-default" (consistent with Bootstrap CSS).

btnText

Text of the 'Browse' button. Default: "Browse".

decimals

Number of decimals in the 'nice_nbytes' presentation of the filesize. Default: 3.

infoClass

The classname(s) of the informative text. Default is "text-muted", another Bootstrap classname.

infoTemplate

  • {imgsize} the image size, in pixels (w x h)
  • {nbytes} the file size in bytes
  • {nice_nbytes} the file size in a more readable format.

Default: '{filename}&emsp;<span class="imgsize">{imgsize}</span><br /><span class="filesize">{nice_nbytes} ({nbytes} bytes)</span>'
