No other JS libraries. This code outputs "string", and the anchor tag's href, as expected, when the link is clicked. $('a.page_item_delete').on('click', function(event){ event.preventDefault(); var $this = $(this); console.log(typeof $this.attr('href')); console.log($this.attr('href')); }); When I activate TinyMCE

问题 what is wrong in this code? I'm trying to get this effect: fadeOut(500) and attr('class','myClass') delayed by 600 millisecs.. then delay(600) again, and fadeIn(500) .
