This is generally how I manage progressive enhancement whilst keep the experience clean, but how safe is it? is there potential for a race condition and this not working?
Imagine the simple abstract scenario, you want to display something differently if you have javascript support.. this is generally what I will end up doing:
<div id="test">original</div>
<script type="text/javascript">
var t = document.getElementById('test');
t.innerHTML = 'changed';
</script>
Many may claim you should use a framework and wait for a domready event, and do changes there.. however there is a significant delay where the 'test' element will have already been rendered before the end of the document and the css are ready and a domready triggers.. thus causing a noticable flicker of 'original'.
Is this code liable to race condition failures? or can I guarentee that an element is discoverable and modifiable if it exists before the script?
Thanks in advance.
