jQuery: datepicker, alert the dayname of the selected
提问by Karem
How can i alert the selected days name? Example 'Monday'.
如何提醒选定的日期名称？例如“星期一”。
So when you pick 7th june 2011 it will alert "Tuesday"
因此，当您选择 2011 年 6 月 7 日时，它会提醒“星期二”
<script>
$(function() {
$( "#date" ).datepicker({
dateFormat: 'dd/mm/yy',
onSelect: function(dateText, inst) {
// how can i grab the day name of the day, example "Monday" and alert it out?
// alert( ? );
}
});
});
</script>

The jQueryUI's Datepicker comes with a formatDatefunction that can do that for you. If you're using a localized version, it'll show the days in that language too.
jQueryUI 的 Datepicker 带有一个formatDate可以为您完成此操作的函数。如果您使用的是本地化版本，它也会以该语言显示日期。
onSelect: function(dateText, inst) {
var date = $(this).datepicker('getDate');
alert($.datepicker.formatDate('DD', date));
}
For more information on localization of on Dapicker's utility functions, have a look at http://jqueryui.com/demos/datepicker/.

this will work if you don't mind showing the name of the day in the input box if you dont like it you can use second hidden input (http://jqueryui.com/demos/datepicker/#alt-field)
如果您不介意在输入框中显示日期名称，这将起作用，如果您不喜欢它，您可以使用第二个隐藏输入（http://jqueryui.com/demos/datepicker/#alt-field）
$(function() {
$( "#date" ).datepicker({
dateFormat: 'DD, d MM, yy',
onSelect: function(dateText, inst) {
var stop = dateText.indexOf(',');
alert( dateText.substring(0, stop));
}
});
});

Use inbuilt function
使用内置函数
$("#datepicker" ).datepicker({ onSelect: function(dateText, inst) {
alert($.datepicker._defaults.dayNames[new Date(dateText).getDay()]);
}});

You can parse a date like this (mm/dd/yyyy):
您可以解析这样的日期 ( mm/dd/yyyy)：
new Date(Date.parse("06/07/2011"))
and use the .getDayfunction. You could do this:
并使用该.getDay功能。你可以这样做：
// parse data
var regexp = /(\d{2})\/(\d{2})\/(\d{2})/.exec("07/06/11");
//form date
var date = new Date(Date.parse(regexp[2] + "/" + regexp[1] + "/20" + regexp[3]));
alert(date.getDay()); // 2 -> Tuesday (starts at 0 = Sunday)
