js判断时间格式是否有效
1 短时间,形如 (13:04:06)
function isTime(str){ var a = str.match(/^(\d{1,2})(:)?(\d{1,2})\2(\d{1,2})$/);if (a == null) {alert('输入的参数不是时间格式'); return false;}if (a[1]>24 || a[3]>60 || a[4]>60){ alert("时间格式不对");return false}return true;}2. 短日期,形如 (2008-07-22)
function strDateTime(str){ var r = str.match(/^(\d{1,4})(-|\/)(\d{1,2})\2(\d{1,2})$/);if(r==null)return false;var d= new Date(r[1], r[3]-1, r[4]);return (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4]);}3 长时间,形如 (2008-07-22 13:04:06)
