jQuery datepicker hover output date

问题

I am using jQuery datepicker and I want to display out the date that the user is currently hovering over. I have the code below (you can also try the code with JSFiddle, http://jsfiddle.net/JGM85/):

$(function() {
    $("#datepicker").datepicker();
    $(".ui-state-default").live("mouseenter", function() {
        $("h1").text($(this).text());
    });
});

​ Currently when hovering over a date, the number of the date (ie. 23) is outputed to the h1 tags. I want to change this so that it outputs the whole date and stores it in a variable.

Any help with this would be appreciated.

回答1:

It's not the best way I did it, because I found nothing in the jQuery UI Datepicker documentation for getting the actual Date, but here you go:

$(function() {
    $("#datepicker").datepicker();
    $(".ui-state-default").on("mouseenter", function() {
        $("h1").text($(this).text()+"."+$(".ui-datepicker-month",$(this).parents()).text()+"."+$(".ui-datepicker-year",$(this).parents()).text());
    });
});

The second version with saving the actual Date + alerting it afterwards:

$(function() {
    $("#datepicker").datepicker();
    $(".ui-state-default").on("mouseenter", function() {
        $("h1").text($(this).text()+"."+$(".ui-datepicker-month",$(this).parents()).text()+"."+$(".ui-datepicker-year",$(this).parents()).text());
    var actualDate=$('h1').text();
        alert(actualDate);
    });
});

UPDATE: I previously had .live as an event handler but .live is no deprecated and .on() is the method to go.
