初始化后ShowDay之前的jQuery datepicker [英] Jquery datepicker beforeShowDay after initializing

问题描述

当我在初始化之后设置ShowShowDay之前不起作用

When I am setting beforeShowDay after initializing it doesn't work

$("#dater").datepicker();

$("#dater").datepicker({
    beforeShowDay: renderCalendarCallback
});

当我第一次更改并在ShowDay之前致电时它将起作用

It will work when I will change and call beforeShowDay for first time

$("#dater").datepicker({
    beforeShowDay: renderCalendarCallback
});

$("#dater").datepicker();

在第一种情况下，如何解决此问题，使其也可以在beforeShowDay之前调用?请注意，我无法删除首次初始化，因为它对我来说是无法到达的.您可以在此jsfiddle http://jsfiddle.net/b6V3W/352/ 中测试这种情况>

How can I fix this to call beforeShowDay in first scenario too? Note that I can't remove first initialization, because it is unreachable for me. You can test this scenarios in this jsfiddle http://jsfiddle.net/b6V3W/352/

推荐答案

对于设置选项初始化后，您需要使用

For setting options after initialization, you need to use the option() method.

$('#dater').datepicker( "option", "beforeShowDay", renderCalendarCallback );
