javascript - 从 Javascript Datepicker 获取工作日名称

Question

我有一个代码片段，它为我提供了从 JSdatepicker 库的日历中选择的日期。

我正在寻找一种方法来获取所选日期的工作日名称，例如:星期一、星期二等...

下面是jsDatepicker的用法:

<script type="text/javascript">
    window.onload = function(){
        new JsDatePick({
            useMode:2,
            target:"inputField1",
            dateFormat:"%Y-%m-%d",
            cellColorScheme:"beige"             
        });

    };
</script>

我查看了 jsDatePicker 中给出的文档但什么也没得到。有人可以帮忙吗？

我也尝试过使用 jQuery Datepicker，但它根本不起作用，下面是 jQuery datepicker 代码:

<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>

<script>    
$(function() {
    $( "#datepicker" ).datepicker();
});
</script>

对于这两种情况，我要选择和显示日期的输入字段是:

<input type="text" id="datepicker"/>

如果您想使用JsDatePick ，这是一种方法:

// Save returning object to variable
var dateSelector = new JsDatePick({
    useMode:2,
    target:"inputField1",
    dateFormat:"%Y-%m-%d",
    cellColorScheme:"beige"             
});

// Use setOnSelectedDelegate to capture clicks
dateSelector.setOnSelectedDelegate(function(){
    // Get selected day from plug-in
    var day = dateSelector.getSelectedDay();

    // Create a JS native Date
    var date = new Date(day.year, day.month, day.day);

    // Get the day of the week (0 is Sunday)
    var dayOfTheWeek = date.getDay();

    // For demonstration purposes, place a string into input field
    var inputField = document.getElementById("inputField1");
    var dayOfTheWeekStr = '';

    switch (dayOfTheWeek) {
        case 0:
            dayOfTheWeekStr = 'Sunday';
            break;
        case 1:
            dayOfTheWeekStr = 'Monday';
            break;
        case 2:
            dayOfTheWeekStr = 'Tuesday';
            break;
        default:
            dayOfTheWeekStr = 'Wed.-Sat.';
            break;
    }

    inputField.value = dayOfTheWeekStr;
});

这是一个JSFiddle .
