本文实例为大家分享了js计时器功能的编写代码,供大家参考,具体内容如下

小白一枚,如有代码不规范或者写错的地方,希望得大神指导

代码:

<!DOCTYPE html>
<html>

<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<title></title>
</head>

<body>
<div id="waitTime"></div>

<script src="js/jquery-git.js"></script>
<script type="text/javascript">
//计时
var time = 0;
var a = setInterval(jishi, 1000); //1000毫秒
var isCanCancerOrder = false;

function jishi() {
time++;

$('#waitTime').html(calTime(time)); //倒计时

if(time == 60) { //1分钟之后
alert("一分钟到啦!");
}
}

function calTime(time) {
var spit = ":";
var hour = "00";
var second = "00";
var min = "00";
var result = "";

if(time % 60 != 0) { //秒
if(time % 60 > 10) {
second = time % 60;
} else {
second = "0" + time % 60;
}
}

if(parseInt(time / 60) != 0) { //分
if(parseInt(time / 60) > 10) {
min = parseInt(time / 60);
} else {
min = "0" + parseInt(time / 60);
}
}

if(parseInt(time / 3600) != 0) { //时
if(parseInt(time / 3600) > 10) {
hour = parseInt(time / 3600);
} else {
hour = "0" + parseInt(time / 3600);
}
}

result = hour + spit + min + spit + second;

return result;
}
</script>
</body>

</html>

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
