问题 I am prepending some data to my page on a button click and instead of just populating immediately on the page, I was wondering if there is a way to animate the prepend() using slideToggle or CSS animation. Here is my current script: var data = $('.data').html(); var insert = '<div class="data-container">'+ data +'</div>'; $('button').click(function(){ $('.data-container').remove(); $('.initial').prepend(insert); }); and a JSFiddle 回答1: You have to do something like this: var data = $('.data')
