ie中for...in...循环不能遍历对象数组

如果数组元素是Element元素的对象，for...in...

先记下。。。

这个不行：

<script type="text/javascript">
var payInput = $('rechPrice');
var fastSelect = $('fastSelect').getElementsByTagName('input');
for(var i in fastSelect){
    fastSelect[i].onclick = function(){payInput.value = this.value;}
}
</script>

这个就可以：

<script type="text/javascript">
var payInput = $('rechPrice');
var fastSelect = $('fastSelect').getElementsByTagName('input');
for(var i = 0 ;i < fastSelect.length;i++){
    fastSelect[i].onclick = function(){payInput.value = this.value;}
}
</script>
