本人JS很菜,下面的代码是很牵强的实现此功能

========================JS文件: servertime.js======================

function RunTime(o) {    function rt()     {      var d = DateAdd("s",1,new Date(o.innerText.replace(/-/g,"/")));   var aaa = "";   aaa = d.getFullYear() ;   var m = d.getMonth()+1;   aaa = aaa + "-"+m;         var da = d.getDate();   aaa = aaa + "-"+da;            aaa = aaa + " ";        var h = d.getHours();   aaa= aaa + h;       var mi = d.getMinutes();           if(mi<10){   aaa = aaa + ":" + "0"+mi;   }else{   aaa = aaa + ":" + mi;   }         var s = d.getSeconds();         if(s<10){   aaa = aaa+ ":" + "0"+s;   }else{     aaa= aaa + ":" + s;   }     o.innerText = aaa;         setTimeout(rt,1000);     }  rt(); } function isIE(){    if (window.navigator.userAgent.toLowerCase().indexOf("msie")>=1)     return true;    else     return false; } if(!isIE()){    HTMLElement.prototype.__defineGetter__(     "innerText",     function(){      var anyString = "";      var childS = this.childNodes;      for(var i=0; i<childS.length; i++) {       if(childS.nodeType==1)        anyString += childS.tagName=="BR" ? '/n' : childS.innerText;       else if(childS.nodeType==3)        anyString += childS.nodeValue;      }      return anyString;     }    );    HTMLElement.prototype.__defineSetter__(     "innerText",     function(sText){      this.textContent=sText;     }    ); } function DateAdd(interval,number,date){  switch(interval.toLowerCase()){   case "y": return new Date(date.setFullYear(date.getFullYear()+number));   case "m": return new Date(date.setMonth(date.getMonth()+number));   case "d": return new Date(date.setDate(date.getDate()+number));   case "w": return new Date(date.setDate(date.getDate()+7*number));   case "h": return new Date(date.setHours(date.getHours()+number));   case "n": return new Date(date.setMinutes(date.getMinutes()+number));   case "s": return new Date(date.setSeconds(date.getSeconds()+number));   case "l": return new Date(date.setMilliseconds(date.getMilliseconds()+number));  } }
