下拉列表中为未来7天

next 7 days in drop-down list

本文关键字：7天 未来 下拉列表      更新时间：2023-09-26

我希望接下来的7天出现在下拉列表中。然而，我的代码似乎不工作。

请注意日期格式必须为yyyy-mm-dd。

你能帮帮我吗?下面是我的代码:

function formatDate(date) {
    var d = new Date(date),
        month = '' + (d.getMonth() + 1),
        day = '' + d.getDate(),
        year = d.getFullYear();
    if (month.length < 2) month = '0' + month;
    if (day.length < 2) day = '0' + day;
    return [year, month, day].join('-');
}
var curr = new Date;
var first = curr.getDate()
var firstday = (new Date(curr.setDate(first))).toString();
for (var i = 0; i < 7; i++) {
    var next = new Date(curr.getTime());
    next.setDate(first + i);
    options += '<option>' + formatDate((next.toString())) + '</option>';
}
$("#datemenu1").append(options);
$("#datemenu1").html("<option>PICK A DATE</option>");
<html>
<select id="datemenu1">
  
  <option>PICK A DATE</option>
  
</select>
<script src="http://code.jquery.com/jquery.min.js"></script>
<script src="Text-1.js"></script>strong text
</html>

这样初始化options = "";:

<html>
    <body>
        <select id="datemenu1">
            <option>PICK A DATE</option>
        </select>
        <script src="http://code.jquery.com/jquery.min.js"></script>
        <script src="Text-1.js"></script>strong text
        <script>
            function formatDate(date) {
                var d = new Date(date),
                        month = '' + (d.getMonth() + 1),
                        day = '' + d.getDate(),
                        year = d.getFullYear();
                if (month.length < 2)
                    month = '0' + month;
                if (day.length < 2)
                    day = '0' + day;
                return [year, month, day].join('-');
            }
            var options = "";
            var curr = new Date;
            var first = curr.getDate()
            var firstday = (new Date(curr.setDate(first))).toString();
            for (var i = 0; i < 7; i++) {
                var next = new Date(curr.getTime());
                next.setDate(first + i);
                options += '<option>' + formatDate((next.toString())) + '</option>';
                $("#datemenu1").append(options);
            }

        </script>
    </body>
</html>

将这一行添加到代码的顶部:

var options = "";

你需要添加

var options = "";

放在for循环的上方，并删除

$("#datemenu1").html("<option>PICK A DATE</option>");

(否则将覆盖所有选项)。
