<form action="" method="">???????? <input type="text" id="txt" />???????? <input type="radio" id="rad" />???????? <input type="checkbox" id="cBox" />???????? <input type="button" value="button" id="btn" /></form><script type="text/javascript">? ? ???? var oTxt=document.getElementById("txt");???????? var oBtn=document.getElementById("btn");???????? oBtn.onclick = function(){ oTxt.focus(); };???????? oTxt.onfocus=function(){???????? alert("我獲得焦點了");???????? }; </script>
javascript 表單獲取焦點，明明只有一條alert，為何谷歌瀏覽器點擊確定仍然會不斷彈屏？
