js 判断所选时间(或者当前时间)是否在某一时间段的实现代码
投稿:mdxy-dxy
这篇文章主要介绍了js 判断所选时间(或者当前时间)是否在某一时间段,需要的朋友可以参考下
核心代码:
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; } var strn = nowTime.split (":"); if (stre.length != 2) { return false; } var b = new Date (); var e = new Date (); var n = new Date (); b.setHours (strb[0]); b.setMinutes (strb[1]); e.setHours (stre[0]); e.setMinutes (stre[1]); n.setHours (strn[0]); n.setMinutes (strn[1]); if (n.getTime () - b.getTime () > 0 && n.getTime () - e.getTime () < 0) { return true; } else { alert ("当前时间是:" + n.getHours () + ":" + n.getMinutes () + ",不在该时间范围内!"); return false; } } time_range ("21:30", "23:30", "3:22");
效果:
当前时间的情况下:
var time_range = function (beginTime, endTime) { var strb = beginTime.split (":"); if (strb.length != 2) { return false; } var stre = endTime.split (":"); if (stre.length != 2) { return false; } var b = new Date (); var e = new Date (); var n = new Date (); b.setHours (strb[0]); b.setMinutes (strb[1]); e.setHours (stre[0]); e.setMinutes (stre[1]); if (n.getTime () - b.getTime () > 0 && n.getTime () - e.getTime () < 0) { return true; } else { alert ("当前时间是:" + n.getHours () + ":" + n.getMinutes () + ",不在该时间范围内!"); return false; } } time_range ("21:30", "23:30");
