|zyciis| 如何让onkeypress 更改输入如输入 A就自动让他的ASCII码加1变成B
如：
<input type="text" onkeypress="AsciiUp(this,event);" />
<script>
function AsciiUp(send,event)
{
????
}
</script>
谢谢
[解决办法]
<input type="text" onkeypress="return AsciiUp(this,event);" /><script>function AsciiUp(obj,e){ var ev = window.event || e; var cd = ev.keyCode || ev.charCode; if(cd >=65 && cd <90 || cd >=97 && cd < 122) { ev.keyCode && (ev.keyCode = ev.keyCode+1); if(ev.charCode){ obj.value=obj.value+String.fromCharCode(ev.charCode+1) ; return false; } }}
