jQuery - resizing form input based on value's width?

Question

Is it possible to get input\'s value width and resize the input dynamically so the value will fit?

Here\'s an example:

this example as been tested on Chrome 25 and Firefox 19. (http://jsfiddle.net/9ezyz/)

function input_update_size()
{
    var value = $(this).val();
    var size  = 12;

    // Looking for font-size into the input
    if (this.currentStyle)
        size = this.currentStyle['font-size'];
    else if (window.getComputedStyle)
        size =  document.defaultView.getComputedStyle(this,null).getPropertyValue('font-size');
    $(this).stop().animate({width:(parseInt(size)/2+1)*value.length},500);
    //$(this).width((parseInt(size)/2+1)*value.length);
}

$('input')
    .each(input_update_size)
    .keyup(input_update_size);
