My97DatePicker,将dateFmt设置为"HH:mm:ss"
<input type="text" onclick="WdatePicker({dateFmt:'HH:mm:ss'})" />
效果:
<head><title></title>
<script>
document.onkeydown = function(e) {
var e = window.event ? window.event : e
if (document.activeElement.id != "txt1")
return
if (e.keyCode == 38) {\\上键事件
var l = getTxt1CursorPosition()
if (l == 2 || l == 8 || l == 5)
return
if (l == 0 || l == 1) {
if (document.getElementById("txt1").value.substr(0, 2) == '24') {
alert('必须小于24小时')
return
}
var val = Number(document.getElementById("txt1").value.substring(0, 2)) + 1
if (val <10) {
document.getElementById("txt1").value = "0" + val + document.getElementById("txt1").value.substring(2, document.getElementById("txt1").value.length)
}
else {
document.getElementById("txt1").value = val + document.getElementById("txt1").value.substring(2, document.getElementById("txt1").value.length)
}
}
}
if (e.keyCode == 40) {\\下键事件
}
}
function getTxt1CursorPosition(){
var oTxt1 = document.getElementById("txt1")
var cursurPosition=-1
if(oTxt1.selectionStart){//非IE浏览器
cursurPosition= oTxt1.selectionStart
}else{//IE
var range = document.selection.createRange()
range.moveStart("character",-oTxt1.value.length)
cursurPosition=range.text.length
}
return cursurPosition
}
</script>
</head>
<body>
<div>
<input id="txt1" type="text" value="00:00:00" />

就不帮你写完了,你按这个思路继续做下键和分、秒就行了。
执行完后文本焦点上还有些小问题,你自己查下,很容易解决。
