使用这个角本后为什么不能删除数字了.要怎么修改?
<script language=javascript>
function onlyNum()
{
if(!((event.keyCode> =48&&event.keyCode <=57)||(event.keyCode> =96&&event.keyCode <=105)))
event.returnValue=false;
}
</script>
<input onkeydown= "onlyNum(); ">
[解决办法]
<script language=javascript>
function onlyNum()
{
if(!((event.keyCode> =48&&event.keyCode <=57)|| (event.keyCode==8)||(event.keyCode> =96&&event.keyCode <=105)))
event.returnValue=false;
}
</script>
<input onkeydown= "onlyNum(); ">
[解决办法]
<script language=javascript>
function onlyNum()
{
if(!((event.keyCode> =48&&event.keyCode <=57)|| (event.keyCode==8)|| （event.keyCode==190）||(event.keyCode> =96&&event.keyCode <=105)))
event.returnValue=false;
}
</script>
<input onkeydown= "onlyNum(); ">

上面的（好象用中文的了，改下：
<script language=javascript>
function onlyNum()
{
if(!((event.keyCode> =48&&event.keyCode <=57)|| (event.keyCode==8)|| (event.keyCode==190)||(event.keyCode> =96&&event.keyCode <=105)))
event.returnValue=false;
}
</script>
<input onkeydown= "onlyNum(); ">
[解决办法]
<script language=javascript>
function onlyNum()
{
if(!((event.keyCode> =48&&event.keyCode <=57)|| (event.keyCode==8)||(event.keyCode==190)||(event.keyCode> =96&&event.keyCode <=105)))
event.returnValue=false;
}
</script>
<input onkeydown= "onlyNum(); ">
