有人可以告诉我我做错了什么吗？我是jquery新手，希望获得一些反馈。基本上我想要的是某种倒数计时器，可以显示事件发生前还剩下多少天。该事件是一个设定的日期。
感谢您的帮助

最佳答案
它必须是：
$(function() {
var myDate = new Date();
myDate.setMonth(06, 06); //set date forward in time, not backward
var today = new Date();
var x = (myDate - today)/86400000;
$('#aantal').text(x); //append to the span, not the p that does not exists
});
