无法获取jQueryUI datepicker选项 beforeShowDay 工作。

Can't get jQueryUI datepicker option beforeShowDay to work.

我尝试过不同的帮助主题已经发现但我无法正常工作。

I've tried different help topics I've found but I can't get it working.

我收到此错误

未捕获的TypeError：无法读取未定义的属性'0'

Uncaught TypeError: Cannot read property '0' of undefined

这是我的JS。但它似乎不起作用

This is my JS. but it doesn't seems to work

<script type="text/javascript">
jQuery(document).ready(function () {
    var your_dates = [new Date(13, 5, 5), new Date(13, 5, 10)];
    jQuery("div#event-calender").datepicker({
        beforeShowDay: function (date) {
            if (jQuery.inArray(date.toString(), your_dates) != -1) {
                return [true, 'highlight'];
            }
        }
    });
});
</script>

推荐答案

您需要始终返回数组，而不仅仅是条件匹配。

You need to always return an array, not just when a condition matches.

来自文档：

beforeShowDay

beforeShowDay

类型：功能（日期日期）

Type: Function( Date date )

将日期作为参数并且必须返回数组的函数

jQuery(document).ready(function () {
    var your_dates = [new Date(13, 5, 5), new Date(13, 5, 10)];
    jQuery("div#event-calender").datepicker({
        beforeShowDay: function (date) {
            var arr;
            if (jQuery.inArray(date.toString(), your_dates) != -1) {
                arr = [true, 'highlight'];
            }else {
                arr = [true, ''];
            }
            return arr;
        }
    });
});
