javascript show in cycle with delay

Simple example:

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

Simple setTimeout using of course doesn开发者_StackOverflow't work... I guess there's should be using closures..

It's a simple matter of writing a recursive function:

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

Should do the job:

for (var i = 0; i < 10; ++i) {
  (function(i) {
     setTimeout(function(){console.log(i);}, i*300);
  })(i);
}

You could use setInterval, like so:

var i = 0;
var id = setInterval(function(){
    if (i == 9) clearInterval(id);
    console.log(i);
    i++;
}, 300);
