Can only obtain element height if browser not maximised

Can only obtain element height if browser not maximised

Can only obtain element height if browser not maximised

(OP)
My pages like [sample page http://www.pdavis.nl/ShowPhoto.php?ID=1201609060] run a function on loading

CODE

<body id=body onload='initialize()'> 
in which I try to read the height (or other property) of elements. However the line

CODE

alert(document.getElementById('map').style.height); 
only returns a value if the browser is not maximised; if it is maximised, I see an empty popup. I don't understand this last result; any help appreciated.

RE: Can only obtain element height if browser not maximised

Hi

JavaScript can only read the style values it set previously.

However you can obtain it through getComputedStyle :

CODE --> JavaScript

getComputedStyle(document.getElementById('map')).height 

Or if your site uses jQuery, that is able to handle it :

CODE --> JavaScript

$('#map').css('height')
