延迟后的jQuery ScrollTop

Question

This code is working nicely to create smooth scroll to the next anchor on my page.

    <script type="text/javascript">  
    $("#blockTwo").on("click", ".child", function( e ) {
         $('html, body').delay(800).animate({
         scrollTop: $('#scrollThree').offset().top
         }, 1500, "swing"); 
    });
    </script>

However, because the content in the anchor element is being loaded via ajax after the click event the animation has a jump mid way through. I thought I could circumnavigate this issue by adding a delay to the animation so that the content is loaded before the animation begins. Not sure if this is either a good idea or feasible?

Thanks

You'll have to place the event listener on the parent and have it bubble up once the element is placed on the page via ajax.

Notice the 2nd parameter of on():

$(".parentElement").on("click", ".child", function( e ) {

Thus, for your specific example:

$("#blockOne").on("click", ".child", function( e ) {

This way, when .click gets loaded in via the ajax, it'll have a listener given to it by its static parent #blockOne. Hope that makes sense.
