Description Box using "onmouseover"

I am playing with the onmouseover event in javascript

I would like a little box to pop up and remain up until there is no onmouseover anymore

I think it's called a description box, but I am not sure.

How do I get a little box to pop up with custom text when I put my mouse over certain text, and disappear once I move the mouse to a different object..?

Solution

  • Assuming popup is the ID of your "description box":

    HTML

    <div id="parent"> <!-- This is the main container, to mouse over -->
<div id="popup" style="display: none">description text here</div>
</div>

    JavaScript

    var e = document.getElementById('parent');
e.onmouseover = function() {
  document.getElementById('popup').style.display = 'block';
}
e.onmouseout = function() {
  document.getElementById('popup').style.display = 'none';
}

    Alternatively you can get rid of JavaScript entirely and do it just with CSS:

    CSS

    #parent #popup {
  display: none;
}

#parent:hover #popup {
  display: block;
}
