看了一些大佬的，方法分装的比较好，但是对小白来说看起来比较绕
本菜鸟自己写了容易理解的
!function () {
var list = []
function f (e) { }
f.prototype.eat = function (e) {
var fn = function () {
console.log('eat | ' + e)
调用()
}
list.push(fn)
return this
}
f.prototype.sleep = function (e) {
var fn = function () {
setTimeout(() => {
console.log('sleep | ' + e)
调用()
}, e * 1000)
}
list.push(fn)
return this
}
f.prototype.firstSleep = function (e) {
var fn = function () {
setTimeout(() => {
console.log('firstSleep | ' + e)
调用()
}, e * 1000)
}
list.unshift(fn)
return this
}
function 调用 () { list.length > 0 && list.shift()() }
window.f = function (e) {
var fn = function () {
console.log('lazyman | ' + e)
调用()
}
list.push(fn)
setTimeout(调用, 0)
return new f()
}
}()
// 下面4行是调用的
f("Hank").sleep(2).eat("dinner")
f("Hank").eat("dinner").eat("supper")
f("Hank").firstSleep(2).eat("supper")
f("Hank").sleep(2).firstSleep(3).eat("supper")
