如果我在JavaScript或jquery中有一个开始日期，我如何显示一周中所有日子的日期?

How Do I display dates of all days of week if I have a start date in JavaScript or jquery?

本文关键字：日期 显示 一周 日子 JavaScript jquery 有一个 如果 开始 何显示      更新时间：2023-09-26

我有一个隐藏的字段，这是支付期的开始日期的日期持有值。现在我必须根据开始日期显示该日期和整个星期的日期。到目前为止，我正在显示星期，但现在我需要显示日期，而不是天。我该如何做到这一点?我只需要显示月和日mm/dd旁边的每一天。Like 12/01 S

隐藏文件值是第一天，这意味着星期六和其他日期应该在那天之后，直到开始日期+6，即，直到F

<div class="form-group" id="buttonsr">
    <div class="btn-group" data-toggle="buttons-checkbox">
        <div class='input-group input-group-sm'>
            <span class="input-group-addon">Week</span>
        </div>
        <button class="btn" name="WeekGroup" id="week_sat">S</button>
        <button class="btn" name="WeekButtonGroup" id="week_sun">S</button>
        <button class="btn" name="WeekGroup" id="week1_mon">M</button>
        <button class="btn" name="WeekGroup" id="week_tue">T</button>
        <button class="btn" name="WeekGroup" id="week_wen">W</button>
        <button class="btn" name="WeekGroup" id="week_thu">T</button>
        <button class="btn" name="WeekGroup" id="week_fri">F</button>
    </div>
</div>

这是你的小提琴JSFIDDLE

和代码

var today = new Date();
var dd = today.getDate();
//This is just for testing, here you set the day!!
dd= 28;
var mm = today.getMonth()+1; //here you must add 1 for january!
//This is just for testing, here you set the month!!
mm = 06;
var yyyy = today.getFullYear();
//adds a zero in front if less than 10
if(dd<10) {
    dd='0'+dd
} 
//adds a zero in front if less than 10
if(mm<10) {
    mm='0'+mm
} 
var buttonContainer = {};
buttonContainer[0] = document.getElementById("week_sat");
buttonContainer[1] = document.getElementById("week_sun");
buttonContainer[2] = document.getElementById("week1_mon");
buttonContainer[3] = document.getElementById("week_tue");
buttonContainer[4] = document.getElementById("week_wen");
buttonContainer[5] = document.getElementById("week_thu");
buttonContainer[6] = document.getElementById("week_fri");
//add to all buttons!
for(var i = 0; i < 7; i++)   
{
    var addedDays = dd + i;
    var monthDays = daysInMonth(mm,yyyy);
    var newMonth = mm;    
    if(monthDays < addedDays)
    {
         newMonth =  parseInt(mm) + 1;
         addedDays = (addedDays - monthDays);
         if(addedDays<10) {
            addedDays='0'+addedDays
         }
    }

    today = newMonth +'/'+ addedDays;
    buttonContainer[i].innerHTML = today + buttonContainer[i].innerHTML;
}
function daysInMonth(month,year) {
    return new Date(year, month, 0).getDate();
}
