Vue全局指令：如何添加全局指令？（附2个常用自定义指令）
然后，在main.js中这个指令，就可以使用了。

var toZeroStr = (val, num = 2) => { num = num || 2; return (new Array(num) .join('0') val) .slice(-num); } var milliseconds2HMS = (diff) => { const millisecond = diff % 1000; diff = diff - millisecond; return seconds2HMS(diff / 1000); } var seconds2HMS = (diff) => { const seconds = diff % 60; const minutes = (diff - seconds) % 3600; // const hours = (diff - minutes - seconds) % 86400; const hours = diff - minutes - seconds; return [hours / 3600, minutes / 60, seconds]; } export default { // 倒计时 countdown: { bind(el, binding, vnode) { const { componentOptions, data } = vnode; const listeners = componentOptions ? componentOptions.listeners : null; const on = data ? data.on : null; const events = listeners ? listeners : on ? on : null; if (events && typeof events === 'object' && Object.keys(events).length) { binding.customListeners = events; } }, inserted(el, binding, vnode) { let val = binding.value; if (!val) { return; } const formatter = vnode.data.attrs.formatter; let timer = null; window.clearInterval(el.timer); const tFunction = () => { val -= 1000; let instance = milliseconds2HMS(val); if (val <= 0) { if (timer) { window.clearInterval(timer); timer = null; if (binding.customListeners) { binding.customListeners.complete && binding.customListeners.complete(); } } el.innerHTML = '0'; return; } el.innerHTML = formatter.replace(/(HH. )(mm. )(ss. )/g, (str, $1, $2, $3) => { return str.replace(new RegExp($1, 'g'), !instance[0] ?
