DEMO

Given:

<div id="x">42</div>

You can do this:

var $x = $('#x');
$x.text(parseInt($x.text(), 10) + 1);

For your education:

• .text()
• parseInt() (and always include the radix argument)

If the div's HTML is simply a number:

var element = document.getElementById('yourElementID');
element.innerHTML = parseInt(element.innerHTML, 10)+1;

Here you use below code

In javascript
--------------
var demoInt = $('#divInt').text();
demoInt =parseInt(demoInt);

In HTML
-------
<div id="divInt">111</div>
