我正在使用Date()函数获取当前日期并将其与另一个日期进行比较.

I am using Date() function to get current date and compare it to another date.

它可以在Android和Web上正常运行，但不能在iOS上运行.

It's working fine with Android and web but it's not working in iOS .

我的代码是:

function daytogo() { var status = document.getElementById('dmy_status').getAttribute('value'); if(status =='C') { var event_status="Event has been cancelled"; } else if(status =='P') { var event_status="Event postponed ! Waiting for new date"; } else { /*START OF CALCULATING DATE DIFFERENCE*/ var oneDay = 24*60*60*1000; // hours*minutes*seconds*milliseconds var a = document.getElementById('dmy_strt').getAttribute('value'); var b = document.getElementById('dmy_end').getAttribute('value'); //var firstDate = new Date(2008,01,12); // alert(b); //alert(firstDate); var today = new Date(); var dd = today.getDate(); var mm = today.getMonth()+1; //January is 0! var yyyy = today.getFullYear(); if(dd<10) { dd='0'+dd } if(mm<10) { mm='0'+mm } today = yyyy+','+mm+','+dd; // document.write(today); var firstDate = new Date(a); var secondDate = new Date(today); var enddate=new Date(b); console.log(firstDate); console.log(secondDate); // alert(today); // var diffDays = Math.abs((firstDate.getTime() - secondDate.getTime())/(oneDay)); // alert(diffDays); if(firstDate > secondDate) { alert("if"); var event_status=''; var diffDays = Math.abs((firstDate.getTime() - secondDate.getTime())/(oneDay)); //alert(diffDays); if(diffDays <=30 ) { event_status=diffDays + " days to go"; } else { event_status=(diffDays /30); event_status=(event_status.toString().split(".")[0])+ ' months to go'; ///before //alert(event_status.toString().split(".")[1]); ///after } } else if(firstDate <= secondDate && enddate >= secondDate) { alert("else if"); var event_status='Ongoing'; } else { alert("else"); var event_status="Event has expired"; //document.getElementById("days_to_go").innerHTML = event_status; } //var elements = document.getElementsByClassName('dmy_strt')[0].value; /*END OF THE DATE DIFFERENCE*/ /*START OF EVENT STATUS */ } document.getElementById("days_to_go").innerHTML = event_status;

日期格式为-'YYYY，mm，dd' 并且我也尝试了"YYYY/mm/dd"格式.

And date format is - 'YYYY,mm,dd' and I have tried 'YYYY/mm/dd' format also.

但是在iOS情况下，总是会出现其他情况(var event_status =事件已过期";).

But in case of iOS it's going to else case always (var event_status="Event has expired";).

我该如何解决?

推荐答案

有四种初始化日期的方法:

There are 4 ways of initiating a date: new Date() new Date(milliseconds) new Date(dateString) new Date(year, month, day, hours, minutes, seconds, milliseconds)

您没有关注任何一个.阅读日期对象的基础.

You don't follow any of them. Read the basics of Date object.
