如题，用到闭包，和setTimeout函数怎么解决？也欢迎php的实现
业精于勤，荒于嬉;行成于思，毁于随。
var count = (function() { var timer; var i = 0; function change(tar) { i++; console.log(i); if (i === tar) { clearTimeout(timer); return false; } timer = setTimeout(function() { change(tar) }, 1000) } return change; })() count(50)
(function(){ var i=0; var end=setInterval(function(){ if(i>=50){ clearInterval(end); } console.log(i); i++; },1000); })()
用setTimeout的话，就不需要clear了。
setTimeout
void function loop(i) { if (i <= 50) { console.log(i); setTimeout(loop.bind(this, ++i), 1000); } }(1);
好像没用到闭包，那么这样吧：
void function loop(i) { if (i <= 50) { console.log(i); setTimeout(function() {loop(++i);}, 1000); } }(1);
OK，这样就有闭包了。
function Count(){
var counter=0; function addCount(){ counter++; console.log(counter); if(counter==50){ return false; } setTimeout(addCount,1000); } return addCount; } var myCount=new Count(); myCount();
var task = function (){ var val = 0; var target = 50; (function add(){ val++; if(val === target) return; setTimeout(add, 1000); })(); }
你这个停不下来吧
