html里插入两个js,这种情况怎么处理
合并成一个就可以了。
注：$(function(){})是 $(document).ready(function() {})的简化写法
$(function(){
$("#news-slider").owlCarousel({
items:3,
itemsDesktop:[1199,2],
itemsDesktopSmall:[980,2],
itemsMobile:[600,1],
pagination:false,
navigationText:false,
autoPlay:true
});
$('#countdown').countDown({
targetDate: {
'day': 5,
'month': 8,
'year': 2024,
'hour': 11,
'min': 0,
'sec': 0
}
});
$('#email_field').focus(email_focus).blur(email_blur);
$('#subscribe_form').bind('submit', function() { return false; });
});

JQuery实现的按钮倒计时效果
本文实例讲述了JQuery实现的按钮倒计时效果。分享给大家供大家参考，具体如下：
一个实现了在按钮上显示倒计时，倒计时完毕自动将按钮设置为不可用的效果，具体代码如下：
html
head
titletest
count
down
button/title
script
src="jquery1.8.3.min.js"
type="text/javascript"/script
script
type="text/javascript"
$(function
()
{
$('#btn').click(function
()
{
var
count
=
10;
var
countdown
=
setInterval(CountDown,
1000);
function
CountDown()
{
$("#btn").attr("disabled",
true);
$("#btn").val("Please
wait
"
+
count
+
"
seconds!");
if
(count
==
0)
{
$("#btn").val("Submit").removeAttr("disabled");
clearInterval(countdown);
}
count--;
}
})
});
/script
/head
body
input
type="button"
id="btn"
value="Submit"
/
/body
/html
运行效果截图如下：
希望本文所述对大家jQuery程序设计有所帮助。

jQuery Countdown 获取的是服务器时间还是本地时间
是本地页面时间，前端一般获取的都是本地时间。
JQuery CountDown里面都是通过new Date的方式和setInterval定时方式进行的。
一般countdown的初始时间最好是从服务器给定，然后倒计时。
