Selenium1.0时代就是用javascript实现的，应该用了类似手段。

<html><head><title>发送模拟按键</title></head><body><div id="mydiv">点击按钮向文字框发送模拟按键（仅对firefox有效）<textarea id="myTextbox" name="yes"></textarea></div><form name="myform" method="get"><input type="button" id="mybtn" value="click me"></form><script type="text/javascript">var btn=document.getElementById("mydiv");var btn=document.getElementById("mybtn");var textbox=document.getElementById("myTextbox");var evt;if(document.implementation.hasFeature("KeyboardEvents","3.0")){evt=document.createEvent("KeyEvents");}mydiv.onclick=function(){textbox.value="";}textbox.onkeydown=function(event){textbox.value=textbox.value+String.fromCharCode(evt.which);}btn.onclick=function(){evt.initKeyEvent("keydown",false,true,document.defaultView,false,false,false,false,97,97);textbox.dispatchEvent(evt);evt.initKeyEvent("keydown",false,true,document.defaultView,false,false,false,false,100,100);textbox.dispatchEvent(evt);evt.initKeyEvent("keydown",false,true,document.defaultView,false,false,false,false,109,109);textbox.dispatchEvent(evt);evt.initKeyEvent("keydown",false,true,document.defaultView,false,false,false,false,105,105);textbox.dispatchEvent(evt);evt.initKeyEvent("keydown",false,true,document.defaultView,false,false,false,false,110,110);textbox.dispatchEvent(evt);}</script></body></html>
