javascript - Have trouble retrieving height property from css file -


everyone.

i pretty sure answer question relatively easy.

i have .css file has following code:

div.site {   text-align:center;   border:2px solid #4b6c9e;    padding:1px;   margin-top:10px;   font-size:medium;   font-family:verdana;   font-weight:bold;   height:25px;  }

then, have .js file builds div xml. here fragment:

txt = txt + "<div class='site'><span class='link'><a class='nav' href=' " + siteurl[0].firstchild.nodevalue + "' target='_blank'>" + sitename[0].firstchild.nodevalue + "</a></span></div>"  document.getelementbyid('portallinks').innerhtml = txt;

my .html file has following:

<div id="portallinks"></div>

i have no problem displaying data on page. have trouble getting height site class .css file. using following code:

var height = $(".site").height();

what want use height, dynamically calculate height portallinks: 

$("#portallinks").css({ "height": newheight }) - newheight calculated based on `height`

thank's in advance.

keep in mind value returned $(".site").height(); not complete css height value. number.

calling $("#portallinks").css({"height": newheight}) result of first call set invalid value of 25. you'll want attach unit variable -- in case, px:

$("#portallinks").css({"height":newheight+'px'});

also, worth mentioning call alone set height of #portallinks height of one .site element.

if want set height combined total, need iterate through results of $('.site') somehow:

var newheight = 0; $(".site").each(function(){     newheight += $(this).height() });  $("#portallinks").css({"height":newheight+'px'});

see fiddle working example: http://jsfiddle.net/ezwx4/

other notes: .height() returns value of css height attribute. not account padding and/or borders.

this cause display problems in cases, should consider using outerheight() instead.

also: using outerheight(true) include defined margins in result.
