javascript在循环中显示延迟

Question

简单的例子:

for (var i = 0; i < 10; ++i) {
  console.log(i); // <--- should be show with delay in 300ms 
}

简单的setTimeout使用当然不起作用......我猜应该使用闭包..

Answer 1

编写递归函数很简单:

function display(i)
{
  if (i == 10) return;    
  setTimeout(function(){ console.log(i); display(i+1); }, 300);
}
