1、js 判断所选时间 （或者当前时间 ）是否在某一时间段 1 var time_range = function (beginTime, endTime,nowTime) var strb = beginTime.split (":");if (strb.length != 2) return false;var stre = endTime.split (":");if (stre.length != 2) return false;101211var strn = nowTime.split (":");13if (stre.len

2、gth != 2) 14return false;191516var b = new Date ();17var e = new Date ();18var n = new Date ();20b.setHours (strb0);21b.setMinutes (strb1);22e.setHours (stre0);23e.setMinutes (stre1);24n.setHours (strn0);25n.setMinutes (strn1);262728return true;29 else if (n.getTime () - b.getTime () > 0 &

3、;amp;&n.getTime () - e.getTime () < 0) 3031return false;alert (" 当前时间是： " + n.getHours () + ":" +");n.getMinutes () + " ，不在该时间范围内！32 33 34 time_range ("21:30", "23:30", "3:22");效果:当前时间的情况下 :1 var time_range = function (beginT

4、ime, endTime) var strb = beginTime.split (":");if (strb.length != 2) return false;var stre = endTime.split (":");if (stre.length != 2) 101112var b = new Date ();13var e = new Date ();14var n = new Date ();1516b.setHours (strb0);17b.setMinutes (strb1);18e.setHours (stre0);19e.setMinutes (stre1);20return false;921if (n.getTime () - b.getTime () > 0 &&n.getTime () - e.getTime () < 0) 22return true;23 else 24alert (" 当前时间是： " + n.getHours () + ":" +H.Hn.getMinutes () + " ，不在该时间范围内！"
