but this way not working, but this working

document.getElementById('spanEmail').innerHTML='sample text>';

How replace this span content?

Answer 1

You haven't closed your href attribute with a double-quote.

href="mailto:'+email+'>

Should be

href="mailto:'+email+'">

Answer 2

You are missing a closing " the code should read:

document.getElementById('spanEmail').innerHTML='<a class="f14 bold rose" href="mailto:'+email+'">'+email+'</a>';
