$(function(){
var week;
if(date.getDay()==0) week="星期日"
if(date.getDay()==1) week="星期一"
if(date.getDay()==2) week="星期二"
if(date.getDay()==3) week="星期三"
if(date.getDay()==4) week="星期四"
if(date.getDay()==5) week="星期五"
if(date.getDay()==6) week="星期六"
return week;
}
alert(getweek(new Date(date)));
var date="2017-10-04";
function getweek(date){var week;
if(date.getDay()==0) week="星期日"
if(date.getDay()==1) week="星期一"
if(date.getDay()==2) week="星期二"
if(date.getDay()==3) week="星期三"
if(date.getDay()==4) week="星期四"
if(date.getDay()==5) week="星期五"
if(date.getDay()==6) week="星期六"
return week;
}
alert(getweek(new Date(date)));
})
如上，可以根據日期，得到星期。
問題來了。在移動端測試的時候，返回的結果有時會出現undefined,
new Date(date)會返回一個Invalid date
解決辦法：
getweek(new Date(date.replace(/-/g,"/")))
將日期由"2017-10-04"替換成"2017/10/04"
