Setting a JS variable and using it in html tag

Question

I have set a variable, and I need to pull in this variable into a html element, but I cant get it to print out the value, this is the code:

<script>
    var randomnumber=Math.floor(Math.random()*11)
</script>

<div id="<script type="text/javascript">document.write(randomnumber)</script>"></div>

Thanks.

Edit: I just used a div as an example, but i need to add a random number to an img tag, as it is for a tracking tag, and needs a unique identifier. Is there a better way to go about this?

Answer 1

Use

<script>
document.write('<div id="'+randomnumber+'" ></div>');
</script>

You can't open a script tag inside an attribute
