JS代码中经常需要做日期大小比较:
这边做个总结:
方法一:
function compareDate(dateTime1,dateTime2) { var formatDate1 = new Date(dateTime1); var formatDate2 = new Date(dateTime2); if(formatDate1 > formatDate2) { return formatDate1; } else { return formatDate2; } } 测试代码: var date = compareDate(“2019-05-01”,“2019-05-05”);//须将日期转换成“YYYY-MM-DD”格式
方法二:
var myDate=new Date(); myDate.setFullYear(2008,8,9); var today = new Date(); if (myDate>today) { alert("Today is before 9th August 2008"); } else { alert("Today is after 9th August 2008"); }
