If the div popup is a modal window of some description, i.e. it is a div overlaying the current page but within the same document, then you can do so by listening for the click event on the modal button and when you see this click, taking the value of the input inside the modal.
Assuming your page setup is similar to the example in the link you posted, if you had an input with an id of input1, and a modal containing an input with id input2, and button with an id of button, then this would be a pure javascript method for achieving the effect you describe.
window.onload = function() {
document.getElementById('button').onclick = function(event) {
event.preventDefault();
document.getElementById('input1').value = document.getElementById('input2').value;
}
};
Here is a fiddle which shows the function working: http://jsfiddle.net/8Z7hg/
The key thing to remember is that you need a way to query the element which contains the data you want to capture (in this case I gave the input an id of 'input2', which I could query using document.getElementById('input2').value and a way to listen to the event which triggers you capturing the data - in this example I created an anonymous function which I bound to the onclick event of the element with an id of button
