要完成此效果需要两个步骤 第一步：把如下代码加入到区域中 <script language="JavaScript"> var timerID = null; var timerRunning = false; // Called by both onLoad in BODY tag, and Resume button. function startclock () { // Make sure the clock is stopped stopclock(); time(); } // Kills clock. function stopclock () { if(timerRunning) clearTimeout(timerID); timerRunning = false; } function time () { var now = new Date(); var yr = now.getYear(); var mName = now.getMonth() + 1; var dName = now.getDay() + 1; var dayNr = ((now.getDate()<10) ? "0" : "")+ now.getDate(); var ampm = (now.getHours() >= 12) ? " P.M." : " A.M." var hours = now.getHours(); hours = ((hours > 12) ? hours - 12 : hours); var minutes = ((now.getMinutes() < 10) ? ":0" : ":") + now.getMinutes(); var seconds = ((now.getSeconds() < 10) ? ":0" : ":") + now.getSeconds(); if(dName==1) Day = "Sunday"; if(dName==2) Day = "Monday"; if(dName==3) Day = "Tuesday"; if(dName==4) Day = "Wednesday"; if(dName==5) Day = "Thursday"; if(dName==6) Day = "Friday"; if(dName==7) Day = "Saturday"; if(mName==1) Month="January"; if(mName==2) Month="February"; if(mName==3) Month="March"; if(mName==4) Month="April"; if(mName==5) Month="May"; if(mName==6) Month="June"; if(mName==7) Month="July"; if(mName==8) Month="August"; if(mName==9) Month="September"; if(mName==10) Month="October"; if(mName==11) Month="November"; if(mName==12) Month="December"; // String to display current date. var DayDateTime=(" " + Day + " " + Month + " " + dayNr + ", " + "" + yr + " " + hours + minutes + seconds + " " + ampm ); // Displays Day-Date-Time on the staus bar. document.clock.face.value=DayDateTime; timerID = setTimeout("time()",1000); timerRunning = true; } // Stops clock and clears status bar. function clearStatus() { if(timerRunning) clearTimeout(timerID); timerRunning = false; window.status=" "; } // -- End Hiding Here --> </script>

第二步：把“onLoad="startclock ()"”加在标记里 例如：
