如何修复跳过每个点击按钮到倒计时的时间? (或每次点击重置倒计时)
How to fix time skipping every click button to countdown? (Or reset countdown every click)
我的倒计时 运行 通常,如果我单击它一次。但是如果我点击它几次,它就会跳过时间。这是我的代码:
<input type="submit" value="Countdown" id="countdown" onclick="countdown_init()" />
<div id="countdown_text"></div>
<script type="application/javascript">
var countdown;
var countdown_number;
var number = document.getElementById('countdown_text');
function countdown_init() {
countdown_number = 6;
countdown_trigger();
}
function countdown_trigger() {
if(countdown_number > 0) {
countdown_number--;
number.innerHTML = countdown_number;
if(countdown_number > 0 ) {
countdown = setTimeout('countdown_trigger()', 1000);
}
}
if(number.innerHTML == "0"){
document.getElementById('countdown_text').innerHTML = "";
}
}
</script>
如何让我每次点击倒计时按钮时重置倒计时计时器?
只需在您的初始化函数中清除它:
function countdown_init() {
clearTimeout(countdown);
countdown_number = 6;
countdown_trigger();
}
