更改类Jquery不起作用

我正在做一个自定义图库,当你点击一个div时它改变了div的src,所以我这样做:

function change2dd1() {
    $("div.videoSel > img").attr("class", "joanamid");
    $("div.videoSel > img").attr('src', $('.videoSel2 > img').attr('src'));
}   

我也尝试更改img的类,这样当我点击它时,我会得到一个全屏版本,我用它:

$('.Fullscreen').css('height', $(document).outerWidth() + 'px');
//for when you click on an image
$('.joanamid').click(function () {
    var src = $('.joanafull').attr('src'); //get the source attribute of the clicked image
    $('.Fullscreen img').attr('src', src); //assign it to the tag for your fullscreen div
    $('.Fullscreen').fadeIn();

    if(imgChecker.height() > imgChecker.width()) {
        $(".Fullscreen img").css({"display":"block", "margin":"5% auto","z-index":"20","top":"0", "width":"30%",
"height":"40%"});
    }
});

问题是更改类根本不起作用,它保持与div首先拥有的相同的类。有什么建议吗?

使用event delegation

$("body").on("click", '.joanamid', funciton() {
  // ...
});
