JavaScript -获取一周中下一天的日期(每一天)
JavaScript -获取一周中下一天的日期(每一天)
提问于 2018-06-14 08:24:59
我已经制作了一个在线日历，我想将日期添加到星期几的旁边。例如，它会显示为Monday (6/18)。我当前的代码运行得相当好，但是从星期一开始获取当前周的第几天。这意味着因为今天是星期三，所以它显示两天前的日期，而不是预期的下周一的日期。
当前代码：
var today = new Date();
var mon = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+1);
var tue = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+2);
var wed = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+3);
var thu = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+4);
var fri = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+5);
var sat = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+6);
var sun = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+7);
$(".mon").html("Monday (" + (mon.getMonth() + 1) + "/" + mon.getDate() + ")");
$(".tue").html("Tuesday (" + (tue.getMonth() + 1) + "/" + tue.getDate() + ")");
$(".wed").html("Wednesday (" + (wed.getMonth() + 1) + "/" + wed.getDate() + ")");
$(".thu").html("Thursday (" + (thu.getMonth() + 1) + "/" + thu.getDate() + ")");
$(".fri").html("Friday (" + (fri.getMonth() + 1) + "/" + fri.getDate() + ")");
$(".sat").html("Saturday (" + (sat.getMonth() + 1) + "/" + sat.getDate() + ")");
$(".sun").html("Sunday (" + (sun.getMonth() + 1) + "/" + sun.getDate() + ")");提前谢谢你！

下面是一个示例：
从今天到接下来的6天。
var arr = [];
var today = new Date();
for(var i=0;i<7;i++){
var date = new Date(today.getFullYear(), today.getMonth(), today.getDate()+i);
arr[date.getDay()] = date;
}
$(".mon").html("Monday (" + (arr[1].getMonth() + 1) + "/" + arr[1].getDate() + ")");
$(".tue").html("Tuesday (" + (arr[2].getMonth() + 1) + "/" + arr[2].getDate() + ")");
$(".wed").html("Wednesday (" + (arr[3].getMonth() + 1) + "/" + arr[3].getDate() + ")");
$(".thu").html("Thursday (" + (arr[4].getMonth() + 1) + "/" + arr[4].getDate() + ")");
$(".fri").html("Friday (" + (arr[5].getMonth() + 1) + "/" + arr[5].getDate() + ")");
$(".sat").html("Saturday (" + (arr[6].getMonth() + 1) + "/" + arr[6].getDate() + ")");
$(".sun").html("Sunday (" + (arr[0].getMonth() + 1) + "/" + arr[0].getDate() + ")");<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span class="mon"></span><br/>
<span class="tue"></span><br/>
<span class="wed"></span><br/>
<span class="thu"></span><br/>
<span class="fri"></span><br/>
<span class="sat"></span><br/>
<span class="sun"></span><br/>
下面是使用函数getNextDay获取给定日期的下一周日期的另一个示例：
var arr = [];
var today = new Date();
for(var i=0;i<7;i++){
arr[i] = getNextDay(today, i);
}
function getNextDay(date, day){
var difference = day - date.getDay();
if(difference < 0)
difference += 7;
return new Date(date.getFullYear(), date.getMonth(), date.getDate() + difference);
}
$(".mon").html("Monday (" + (arr[1].getMonth() + 1) + "/" + arr[1].getDate() + ")");
$(".tue").html("Tuesday (" + (arr[2].getMonth() + 1) + "/" + arr[2].getDate() + ")");
$(".wed").html("Wednesday (" + (arr[3].getMonth() + 1) + "/" + arr[3].getDate() + ")");
$(".thu").html("Thursday (" + (arr[4].getMonth() + 1) + "/" + arr[4].getDate() + ")");
$(".fri").html("Friday (" + (arr[5].getMonth() + 1) + "/" + arr[5].getDate() + ")");
$(".sat").html("Saturday (" + (arr[6].getMonth() + 1) + "/" + arr[6].getDate() + ")");
$(".sun").html("Sunday (" + (arr[0].getMonth() + 1) + "/" + arr[0].getDate() + ")");<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span class="mon"></span><br/>
<span class="tue"></span><br/>
<span class="wed"></span><br/>
<span class="thu"></span><br/>
<span class="fri"></span><br/>
<span class="sat"></span><br/>
<span class="sun"></span><br/>

如果你想看看下周的数值，为什么不多加7呢？
var mon = new Date(today.getFullYear(), today.getMonth(), today.getDate() - today.getDay()+8);
