Slow down my javascript! How do I let my code wait for a transition to complete before it completes?

Question

Strange question, I think, but I have this bit of code on my page ...

$(".map-overlay-left").click(function () {  
    $("#map-holder").hide('slow');                                  
    var gmarkers = [];
    var side_bar_html = "";

    var map = new GMap2(document.getElementById('map-holder'));
    map.addControl(new GSmallMapControl());
    map.addControl(new GMapTypeControl());
    var Africa = new GLatLng(-2.767478,23.730469);
    map.setCenter(Africa, 4);   

    $.get("http://xx.xxx.xxxx.xxx/xml-feed-google-maps",{},function(xml) {
        $('marker',xml).each(function(i) {
            html = $(this).text();
            lat = $(this).attr("lat");
            lng = $(this).attr("lng");
            label = $(this).attr("label");
            var point = new GLatLng(lat,lng);
            var marker = createMarker(point,label,html);
            map.addOverlay(marker);
        });
    });

    $("#map-holder").show('slow');
});

It works fantastically and does what I want functionally just not UI wise. This meant first making a good transition to hide the “map holder” div, displaying the google map inside it, and then making a good transition back to size. Transition is show / hide jQuery by default.

Now the problem that I seem to get is that the Google map is displayed while this one $("#map-holder").hide('slow');is still working, and you see glimpses of the map before it hides and then opens again, which causes a bewildering effect.

.hide :

$("#map-holder").hide('slow', function() {
  var gmarkers = [];
  var side_bar_html = "";      

  // ...

  $("#map-holder").show('slow');

this SO, vanilla JS.

function whichTransitionEvent(){
    var t;
    var el = document.createElement('fakeelement');
    var transitions = {
      'transition':'transitionend',
      'OTransition':'oTransitionEnd',
      'MozTransition':'transitionend',

    for(t in transitions){
        if( el.style[t] !== undefined ){
            return transitions[t];

var transitionEnd = whichTransitionEvent();
element.addEventListener(transitionEnd, theFunctionToInvoke, false);

function theFunctionToInvoke(){
