Question

I used the following jquery to insert a metatag into a html document.

<script type="text/javascript">
if(screen.width>=320 && screen.width<=767){
$('head').append('<meta id="viewport" name="viewport" content="width=320; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;">');}    
</script>

If possible, I’d like to insert the metatag without using jquery. Anyone have any ideas how I can do that?

I believe I will probably need to use document.getElementByTagName but I’m not sure how.

Just in case you are wondering, I am inserting the metatag into my html to to optomize the site for viewing with the iphone.
Unfortunately, width=device-width is not an option as it doesn’t play well with my ipad version.

var viewPortTag=document.createElement('meta');
viewPortTag.id="viewport";
viewPortTag.name = "viewport";
viewPortTag.content = "width=320, initial-scale=1.0, maximum-scale=1.0, user-scalable=0";
document.getElementsByTagName('head')[0].appendChild(viewPortTag);
