插件说明
jquery.countup.js是一款轻量级jquery数字动画插件。该数字动画插件可以在页面滚动时,将指定的数字从0开始计数增加动画。
该数字动画插件可以控制动画的延迟时间和动画过渡时间。它依赖于Waypoints插件来监听滚动事件。
安装
可以通过npm或bower来安装jquery.countup.js插件。
1
2
npm install jquery.countup.js
bower install jquery.countup.js
使用方法
在页面引入jquery,jquery.waypoints.min.js和jquery.countup.min.js文件。

你也可以使用data-counter-time和data-counter-delay属性来设置数字动画的动画时间和延迟时间。

初始化插件
在页面DOM元素加载完毕之后,可以通过countUp()方法来初始化数字动画。
1
$('.counter').countUp();
也可以在初始化的时候传入配置参数。

4
$('.counter').countUp({
delay: 10,
time: 2000
});
delay:每个数字动画的延迟时间,单位毫秒。
time:计数动画总的持续时间。

公司项目效果:
为了让数字小的 ,先停止,所以又加了一个定时器。
直接上代码:
700
32,479,432,100
12,440
function startRun() {
$('.counter1').countUp({
// delay: 10,
time: 2000
});
$('.counter2').countUp({
// delay: 10,
time: 3000
});
$('.counter3').countUp({
// delay: 10,
time: 3800
});
timer1 = setTimeout(startRun, 10000);
}
startRun()
送两个插件源码:
countup.js:
!function(t){"use strict";t.fn.countUp=function(e){var a=t.extend({time:2e3,delay:10},e);return this.each(function(){var e=t(this),n=a,u=function(){e.data("counterupTo")||e.data("counterupTo",e.text());var t=parseInt(e.data("counter-time"))>0?parseInt(e.data("counter-time")):n.time,a=parseInt(e.data("counter-delay"))>0?parseInt(e.data("counter-delay")):n.delay,u=t/a,r=e.data("counterupTo"),o=[r],c=/[0-9]+,[0-9]+/.test(r);r=r.replace(/,/g,"");for(var d=(/^[0-9]+$/.test(r),/^[0-9]+.[0-9]+$/.test(r)),s=d?(r.split(".")[1]||[]).length:0,i=u;i>=1;i--){var p=parseInt(Math.round(r/ui));if(d&&(p=parseFloat(r/ui).toFixed(s)),c)for(;/(d+)(d{3})/.test(p.toString());)p=p.toString().replace(/(d+)(d{3})/,"$1,$2");o.unshift(p)}e.data("counterup-nums",o),e.text("0");var f=function(){e.text(e.data("counterup-nums").shift()),e.data("counterup-nums").length?setTimeout(e.data("counterup-func"),a):(delete e.data("counterup-nums"),e.data("counterup-nums",null),e.data("counterup-func",null))};e.data("counterup-func",f),setTimeout(e.data("counterup-func"),a)};e.waypoint(u,{offset:"100%",triggerOnce:!0})})}}(jQuery);
