使用jquery datepicker选择选择日期的星期数 [英] Select the week number of the date picked using jquery datepicker

问题描述

我有以下代码来选择一个日期，然后将其转换为星期数.

I have the following code for selecting a date which I then want to convert to a week number.

    $(".calendar").datepicker({
        showWeek: true,
        onSelect: function(dateText, inst) {
            dateFormat: "'Week Number '" + $.datepicker.iso8601Week(new Date(dateText)),
            alert($.datepicker.iso8601Week(new Date(dateText)))
        }
    });

警报显示正确的星期数，但日期根本没有重新格式化.

The alert shows the correct week number, but the date does not reformat at all.

我无法将dateFormat函数移到onSelect之外，因为这不会导致任何事情发生.

I can't move the dateFormat function outside of the onSelect because this causes nothing to happen.

我想实现的是在文本字段中输入类似第13周"的字样

What I would like to achieve is the text field to say something like "Week Number 13"

有什么想法吗?

在onselect事件中，您需要使用.val()覆盖文本框值的设置

In the onselect event, you need to use .val() to override the setting of the textbox value

$(".calendar").datepicker({
        showWeek: true,
        onSelect: function(dateText, inst) {
            $(this).val("'Week Number '" + $.datepicker.iso8601Week(new Date(dateText)));
        }
    });​

编辑

正如Igor Shastin在下面的评论中指出的那样，我们已经在 inst.input

As Igor Shastin pointed out in his comment below we already have the text box in inst.input

inst.input.val($.datepicker.iso8601Week(new Date(dateText)));
