javascript判断时间段的实现代码

交易时间开始:  交易时间结束:  var v = $('#bcconDateBeginDate').datetimebox('getValue'); if(v.length>0){ var date = new Date(); var year = date.getFullYear(); var month = date.getMonth() + 1; var strDate = date.getDate(); if (month >= 1 && month <= 9) { month = "0" + month; } if (strDate >= 0 && strDate <= 9) { strDate = "0" + strDate; } var nowdate = year+"/"+month+"/"+strDate; var data1 = Date.parse(v.substring(0,10).replace(/-/g,"/")); var data2 = Date.parse(nowdate); var datadiff = data2-data1; var time = 6*24*60*60*1000; if(datadiff>time){ $.messager.alert('提示', '开始时间不能超过当前时间前7天!'); return; } }
