我是谁CONTENTEDITABLE属性已被设置为true.How我会得到孩子们对键盘事件作出响应一个div? 似乎是唯一的办法是捕捉事件在父DIV,并通过选择的API搞清楚孩子。 有没有更好的办法? 更具体地讲,我可以将键盘事件处理程序的子元素? 我缺少的东西吗?
附件是说明该问题的示例代码。 希望在代码注释足够解释。

<span id="span1" onkeypress="alert('span1 keypress')">test text 1</span> <!-- does not work -->
<span id="span2" > test text2</span>
<span id="span3" onclick="alert('span3 clicked')">test text 3</span> <!-- this works fine -->

<!-- Uncomment this to set a keypress handler for span2 programatically. still doesnt work -->

<script type="text/javascript">
var span2 = document.getElementById('span2');
span2.onkeypress=function() {alert('keypressed on ='+this.id)};
</script>

<!-- Uncomment this to enable keyboard events for the whole div. Finding the actual child that the event is happening on requires using the selection api -->

<script type="text/javascript">
var editable = document.getElementById('editable');
editable.onkeypress=function() {alert('key pressed on ='+this.id+';selnode='+getSelection().anchorNode.parentNode.id+',offset='+getSelection().getRangeAt(0).startOffset)};
