问题描述
所以可能是一个简单的问题，但我正在尝试使用 JS 中的 SimplyCountdown 进行倒计时.现在，我更改了参数并且日期不会重置.我尝试了多种方法，但仍然存在相同的问题.有人可以帮我吗?
So might be a simple question, but I'm trying to do a countdown with SimplyCountdown in JS. Now, I change the parameter and the date doesn't reset. I tried multiple things, but it still has the same issue. Can anyone help me with it?
这是我在 index.html 中的代码.
That's my code within index.html.
<script>
var d = new Date(new Date().getTime() + 200 * 120 * 120 * 2000);
// default example
simplyCountdown('.simply-countdown-one', {
year: d.getFullYear(),
month: d.getMonth() + 1,
day: d.getDate()
});
//jQuery example
$('#simply-countdown-losange').simplyCountdown({
year: d.getFullYear(),
month: d.getMonth() + 1,
day: d.getDate(),
enableUtc: false
});
</script>
我的 JS 看起来像这样.
My JS looks like this.
(function (exports) {
'use strict';
var // functions
extend,
createElements,
createCountdownElt,
simplyCountdown;
/**
* Function that merge user parameters with defaults one.
* @param out
* @returns {*|{}}
*/
extend = function (out) {
var i,
obj,
key;
out = out || {};
for (i = 1; i < arguments.length; i += 1) {
obj = arguments[i];
if (obj) {
for (key in obj) {
if (obj.hasOwnProperty(key)) {
if (typeof obj[key] === 'object') {
extend(out[key], obj[key]);
} else {
out[key] = obj[key];
}
}
}
}
}
return out;
};
/**
* Function that create a countdown section
* @param countdown
* @param parameters
* @param typeClass
* @returns {{full: (*|Element), amount: (*|Element), word: (*|Element)}}
*/
createCountdownElt = function (countdown, parameters, typeClass) {
var innerSectionTag,
sectionTag,
amountTag,
wordTag;
sectionTag = document.createElement('div');
amountTag = document.createElement('span');
wordTag = document.createElement('span');
innerSectionTag = document.createElement('div');
innerSectionTag.appendChild(amountTag);
innerSectionTag.appendChild(wordTag);
sectionTag.appendChild(innerSectionTag);
sectionTag.classList.add(parameters.sectionClass);
sectionTag.classList.add(typeClass);
amountTag.classList.add(parameters.amountClass);
wordTag.classList.add(parameters.wordClass);
countdown.appendChild(sectionTag);
return {
full: sectionTag,
amount: amountTag,
word: wordTag
};
};
/**
* Function that create full countdown DOM elements calling createCountdownElt
* @param parameters
* @param countdown
* @returns {{days: (*|Element), hours: (*|Element), minutes: (*|Element), seconds: (*|Element)}}
*/
createElements = function (parameters, countdown) {
var spanTag;
if (!parameters.inline) {
return {
days: createCountdownElt(countdown, parameters, 'simply-days-section'),
hours: createCountdownElt(countdown, parameters, 'simply-hours-section'),

}

非常感谢您的帮助！
推荐答案
这就是我所做的
$('#simply-countdown-losange').simplyCountdown({
year: 2017,
month: 12,
day: 25,
enableUtc: true
});
