setTimeout 显示问题

<div id="test"></div>
<script>
var str="1,2,3,4,5";
str = str.split(',');
for(var i = 0, len = str.length; i < len; i++){
(function(x){
setTimeout(function(){
document.getElementById('test').innerHTML += str[x]
},1000)
})(i)
}
</script>
这段代码为什么没有每隔一秒这样显示
1
12
123
1234
12345而是直接隔一秒后直接 12345？期待

<script>
    var str="1,2,3,4,5",count = 0,inter = null;
    str = str.split(',');

inter = setInterval(function(){
if(str[count]){
document.getElementById('test').innerHTML = str[count];
count++;
}else{
clearInterval(inter)
}
},1000)

</script></body>
</html>
document.getElementById('test').innerHTML = str[count];把这句改成document.getElementById('test').innerHTML += str[count];就是你要的效果~·
