你可以尝试用脚本给这个iframe附加事件
var oframe = document.getElementById("iframe的name").contentWindow;
oframe.onbulr = function(){....}
oframe.onfocus = function(){....}
var oframe = document.getElementById("iframe的name").contentWindow;
oframe.onbulr = function(){....}
oframe.onfocus = function(){....}
FireFox返回iframe的类型为[object XPCCrossOriginWrapper [object HTMLIFrameElement]]
window.setTimeout( function(){ obj.focus(); }, 0);
</iframe>
<script>
window.setTimeout( function(){alert(1); document.getElementById("AA").focus(); }, 0);
</script>看看
