如何实现在下拉菜单里输入文字?
<script> function pp(){ se.options[2]=new Option(ok=(se.options[2])?se.options[2].innerText+String.fromCharCode (event.keyCode):String.fromCharCode(event.keyCode),"client") se.selectedIndex=2; }
function edit(){ if(se.options[2]){ if(event.keyCode==8){ var str=se.options[2].innerText; var len=str.length; se.options[2].innerText=str.substring(0,len-1); if(se.options[2].innerText=="")se.remove(2); } if(event.keyCode==13)return false; if(event.keyCode==32){ se.options[2].innerText+=" "; } } } </script> <select id=se onkeypress=pp() onkeyup="edit()"> <option>山水盈盈之输入文字 </select> |
