【源码 ngx】【广州小程序源码】【直捣黄龙 源码】hours源码
1.将以下jq代码转换为原生js
2.求在HTML页上显示动态标准时间代码
3.用JS获取当前时间（小时分钟秒） 然后绑定三个button按钮 一个按钮增加一小时，一个减少一个小时
将以下jq代码转换为原生js
jquery.downCount.js是依赖于jQuery的插件（效果：倒计时），所以我们需要查看该插件的源码才能将其变成源生代码。html代码：
<div class="p1"><span class="days"></span><span class="days_ref"></span>
<span class="hours"></span><span class="hours_ref"></span>
<span class="minutes"></span><span class="minutes_ref"></span>
<span class="seconds"></span><span class="seconds_ref"></span>
</div>
上面span中的源码 ngxclass类是用于显示需要的类，在插件中days、hours、广州小程序源码minutes、seconds分别用于显示天数、小时、分钟、秒，days_ref、hours_ref、直捣黄龙 源码minutes_ref、seconds_ref分别用于显示单位days或day，hours或hour、微信发卡源码minutes或minute、seconds或second。这些类都没有定义相应的幸运夺宝网站源码样式，需要自己自定义样式。
js代码，只是简易的提了出来，如果需要更灵活的配置，自己再做进一步封装：
(function () {var container = document.querySelector(".p1");
var mydate = '1// ::',
myoffset = ,
callback = function () {
alert("执行完毕");
};
/
*** Change client's local date to match offset timezone
* @return { Object} Fixed Date object.
*/
var currentDate = function () {
// get client's current date
var date = new Date();
// turn date to utc
var utc = date.getTime() + (date.getTimezoneOffset() * );
// set new Date object
var new_date = new Date(utc + (*myoffset));
return new_date;
};
/
*** Main downCount function that calculates everything
*/
function countdown () {
var target_date = new Date(mydate), // set target date
current_date = currentDate(); // get fixed current date
// difference of dates
var difference = target_date - current_date;
// if difference is negative than it's pass the target date
if (difference < 0) {
// stop timer
clearInterval(interval);
if (callback && typeof callback === 'function') {
callback();
}
return;
}
// basic math variables
var _second = ,
_minute = _second * ,
_hour = _minute * ,
_day = _hour * ;
// calculate dates
var days = Math.floor(difference / _day),
hours = Math.floor((difference % _day) / _hour),
minutes = Math.floor((difference % _hour) / _minute),
seconds = Math.floor((difference % _minute) / _second),
// fix dates so that it will show two digets
days = (String(days).length >= 2) ? days : '0' + days,
hours = (String(hours).length >= 2) ? hours : '0' + hours,
minutes = (String(minutes).length >= 2) ? minutes : '0' + minutes,
seconds = (String(seconds).length >= 2) ? seconds : '0' + seconds;
// based on the date change the refrence wording
var ref_days = (days === 1) ? 'day' : 'days',
ref_hours = (hours === 1) ? 'hour' : 'hours',
ref_minutes = (minutes === 1) ? 'minute' : 'minutes',
ref_seconds = (seconds === 1) ? 'second' : 'seconds';
// set to DOM
document.querySelector('.days').innerHTML = days;
document.querySelector('.hours').innerHTML = hours;
document.querySelector('.minutes').innerHTML = minutes;
document.querySelector('.seconds').innerHTML = seconds;
document.querySelector('.days_ref').innerHTML = ref_days;
document.querySelector('.hours_ref').innerHTML = ref_hours;
document.querySelector('.minutes_ref').innerHTML = ref_minutes;
document.querySelector('.seconds_ref').innerHTML = ref_seconds;
};
// start
var interval = setInterval(countdown, );
})();
