Detecting div height when resizing

Question

I am trying to determine the height of the div into which I am loading the content. This div does not have a certain height, since I load pages into it, and they themselves fill the div in different amounts. I think the code I use does not work.

#content divgets the correct height on document load, however I cannot get the height when I click on load.

HTML:

<div id="select">
<div id="menu">
    <ul>
    <li><a class="load" href="javascript:void(0)" id="p1">P1</a></li>
    <li><a class="load" href="javascript:void(0)" id="p2">P2</a></li>
    </ul>
</div>
<div id="spacer"></div>
<div id="content"></div>

CSS

#content {
    left: 227px;
    top: 20px;
    width: 703px;
    padding: 0 0 100px 0;
    position: absolute;
}

#spacer {
    border-right: 2px solid #000000;
    left: 10px;
    position: absolute;
    top: 710px;
    width: 215px;
}

my jquery:

$(document).ready(function() {
    //Load Initial Content
    $("#content").html('<ul><li>Loading Content...</li></ul>')
        .load("/content/" + "projects.php", null, function() {
            contentHeight = $("#content").height();
            selectHeight = $("#select").height();

            $("#content").height(contentHeight);
            $("#select").height(selectHeight);
            $("#spacer").height((contentHeight - selectHeight - 40) + "px")
                        .css({"top": selectHeight + 40 + "px" });
            });

    //Load content on click function
    $(".load").click(function(){
        loadName = $(this).attr("id");
        $("#content").html('<ul><li>Loading Content...</li></ul>')
                     .load("/content/" + loadName + ".php", null, function(){
                         contentHeight = $("#content").height();
                         selectHeight = $("#select").height();

                         $("#spacer").height(0);

                         if(selectHeight > contentHeight) {
                         $("#spacer").css({"display": "none"}); 
                         }else{

                         $("#spacer").css({"top": selectHeight + 40 + "px", "display": "block" })
                                     .height((contentHeight - selectHeight - 40) + "px");
                         return false;
                         }
                         });
    });
});

I get this in firebug on boot:

<div id="select" style="height: 689px;"/>
<div id="spacer" style="height: 5461px; top: 729px;"/>
<div id="content" style="height: 6190px;"/>

Now, if I click on P2, the div with the height of the content will remain the same, although the actual content inside the div is only 625px tall; therefore it does not switch.

//Get Content size after load
$("#content").bind("resize", function(){ 
                    $("#content").css({"height": $("#content").height()}); 
                    });

"px"

//Get Content size after load
$("#content").bind("resize", function(){ 
                    $("#content").css({"height": $("#content").height() + "px"}); 
                    });

EDIT

, click:

$("#spacer").css({"height": $("#content").height() + "px"}); //added parenthesis enables the #spacer div to change height accordingly

I like to use offsetheight to determine the height when it is not set.
