Java Script中客户端日期如何验证？急！万分感谢！

Question

看看下面的 
str = 要验证的日期字符串
         var temp="";
   var tempy='';  //year
   var tempm='';  //month
   var tempd='';  //date
   var tempArray; //store the date
   if(str.length<8 && str.length>10)
   {
 temp = temp + "“" + lable + "”" + "日期长度为8-10位！" + "\n";
}
   tempArray = str.split('-');  //split the str by '-'
   if (tempArray.length!=3)
   {
temp = temp + "“" + lable + "”" + "日期格式不对！正确的应为(年-月-日)" + "\n";
   }
   if (tempArray[0].length==4)
   {
      tempy = tempArray[0];
      tempm = tempArray[1];
      tempd = tempArray[2];
   }
   else
   {
temp = temp + "“" + lable + "”" + "日期格式不对！正确的应为(年-月-日)" + "\n";
   }
   var tstr = tempy + '/'+tempm + '/'+tempd+' 8:0:0';
   var tempDate = new Date(tstr);
   if (isNaN(tempDate))  temp = temp + "“" + lable + "”" + "无效的日期输入！" + "\n";
   if (((tempDate.getUTCFullYear()).toString()==tempy) && (tempDate.getMonth()==eval(tempm+'-1')) && (tempDate.getDate()==eval(tempd)))
      temp = temp;
   else
   {
temp = temp + "“" + lable + "”" + "无效的日期输入！" + "\n";
   }
如果temp==""则表示日期正确,否则,为出错信息

一个通用验证javascript函数--------------------------------------------------------------------------------

很久以前写的一个通用验证函数，大家不要笑啊，许多东西没有完善比如日期验证。
