JavaScriptdate（）函数不适用于Safari（iOS）
我使用Date（）函数获取当前date并将其与另一个date进行比较。
它与Android和networking工作正常，但它不适用于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; date格式是 – 'YYYY，mm，dd'，我也尝试了'YYYY / mm / dd'格式。
但在iOS的情况下，总是会遇到其他情况（var event_status =“Event has expired”;）。
我该如何解决这个问题？
有4种启动date的方法：
new Date() new Date(milliseconds) new Date(dateString) new Date(year, month, day, hours, minutes, seconds, milliseconds)
你不关注他们中的任何一个。 阅读Date对象的基础知识 。
