Answer 1

html
<div id='myDiv'>Some Text</div>

js
var myDiv=document.getElementById('myDiv');

to access the text simply use the innerHTML of the div:

myDiv.innerHTML = 'different text';
this will change the text
if you want to hide it however you can use

myDiv.style.visibility = 'hidden';
or
myDiv.style.visibility = 'visible';

myDiv.style.display = 'none';
