How to use a JavaScript variable inside HTML tag , consider the following example.

HTML

<script> var tbIndx = 10 ;/script> 
.
.
.
<input type="text" name="someInput" value="?">

I want the attribute 'value' to have the value of the variable tbIndx instead of '?', so how to?

I tried ${tbIndx} and &{tbIndx}; but both didn't work.

Please help
