Question

My following javascript file displays nothing , although I was expecting a link there . Somebody please tell me the reason

<p id="demo"></p>

<script type="text/javascript">

var u = 'somewebsite';
var q += '<a href="'+u+'">';
var q += '</a>';

document.getElementById("demo").innerHTML=q;
</script>

Answer 1

several things going wrong here. First, as shelman says, q isn’t being initialised. Secondly using var is redefining the variable. And thirdly, your link has no content:

var u = 'somewebsite';
var q = '<a href="'+u+'">';
q += u;
q += '</a>';
