 1  function parseISO8601(dateStringInRange) {  
   var isoExp = /^\s*(\d{4})-(\d\d)-(\d\d)\s*$/,  
       date = new Date(NaN), month,  
       parts = isoExp.exec(dateStringInRange);  
  
   if(parts) {  
     month = +parts[2];  
     date.setFullYear(parts[1], month - 1, parts[3]);  
     if(month != date.getMonth() + 1) {  
       date.setTime(NaN);  
     }  
   }  
   return date;  
 }  

ajax后台返回格式为"XXXX-XX-XXTXX:XX:XX"

调用方式：var BeginTime = new Date(parseISO8601(m_ProjectTEN.BeginTime.split('T')[0]));
