js的成员和方法好象没有private和public之分,列一下public的成员和方法成员:name 控件的名字,既这个控件的变量名(必选)fName 时间的input的name,可以后台获取,也就是input的name属性(可选,默认为 m_input方法:play() 使时间框呈现动态效果getTime() 获取设定的时间IE5.5+效果最佳,IE5运行也没有问题,就是css有些对不齐(IE5实在是太老了。。。可以退休了)运行代码框<style type="text/css"body {background-color: #D4D0C8;}.m_frameborder {border-left: 2px inset #D4D0C8;border-top: 2px inset #D4D0C8;border-right: 2px inset #FFFFFF;border-bottom: 2px inset #FFFFFF;width: 100px;height: 19px;background-color: #FFFFFF;overflow: hidden;text-align: right;font-family: "Tahoma";font-size: 10px;}.m_arrow {width: 16px;height: 8px;font-family: "Webdings";font-size: 7px;line-height: 2px;padding-left: 2px;cursor: default;}.m_input {width: 18px;height: 14px;border: 0px solid black;font-family: "Tahoma";font-size: 9px;text-align: right;}</style<script language="javascript"//Written by cloudchen, 2004/03/15function minute(name,fName) {this.name = name;this.fName = fName || "m_input";this.timer = null;this.fObj = null;this.toString = function() {var objDate = new Date();var sMinute_Common = "class="m_input" maxlength="2" name=""+this.fName+"" onfocus=""+this.name+".setFocusObj(this)" onblur=""+this.name+".setTime(this)" onkeyup=""+this.name+".prevent(this)" onkeypress="if (!/[0-9]/.test(String.fromCharCode(event.keyCode)))event.keyCode=0" onpaste="return false" ondragenter="return false" style="ime-mode:disabled"";var sButton_Common = "class="m_arrow" onfocus="this.blur()" onmouseup=""+this.name+".controlTime()" disabled"var str = "";str += "<table border="0" cellspacing="0" cellpadding="0""str += "<tr"str += "<td"str += "<div class="m_frameborder""str += "<input radix="24" value=""+this.formatTime(objDate.getHours())+"" "+sMinute_Common+":"str += "<input radix="60" value=""+this.formatTime(objDate.getMinutes())+"" "+sMinute_Common+":"str += "<input radix="60" value=""+this.formatTime(objDate.getSeconds())+"" "+sMinute_Common+""str += "</div"str += "</td"str += "<td"str += "<table border="0" cellspacing="2" cellpadding="0""str += "<tr<td<button id=""+this.fName+"_up" "+sButton_Common+"5</button</td</tr"str += "<tr<td<button id=""+this.fName+"_down" "+sButton_Common+"6</button</td</tr"str += "</table"str += "</td"str += "</tr"str += "</table"return str;}this.play = function() {this.timer = setInterval(this.name+".playback()",1000);}this.formatTime = function(sTime) {sTime = ("0"+sTime);return sTime.substr(sTime.length-2);}this.playback = function() {var objDate = new Date();var arrDate = [objDate.getHours(),objDate.getMinutes(),objDate.getSeconds()];var objMinute = document.getElementsByName(this.fName);for (var i=0;i<objMinute.length;i++) {objMinute[i].value = this.formatTime(arrDate[i])}}this.prevent = function(obj) {clearInterval(this.timer);this.setFocusObj(obj);var value = parseInt(obj.value,10);var radix = parseInt(obj.radix,10)-1;if (obj.valueradix||obj.value<0) {obj.value = obj.value.substr(0,1);}}this.controlTime = function(cmd) {event.cancelBubble = true;if (!this.fObj) return;clearInterval(this.timer);var cmd = event.srcElement.innerText=="5"?true:false;var i = parseInt(this.fObj.value,10);var radix = parseInt(this.fObj.radix,10)-1;if (i==radix&&cmd) {i = 0;} else if (i==0&&!cmd) {i = radix;} else {cmd?i++:i--;}this.fObj.value = this.formatTime(i);this.fObj.select();}this.setTime = function(obj) {obj.value = this.formatTime(obj.value);}this.setFocusObj = function(obj) {ev
