Question

感谢您post我知道如何创建一个日期选择器。

不幸的是，我不能让datepicker始终可见，不仅仅是当有人点击该字段时。

我使用小修改here制作原始小提琴的叉子。在这个副本中我有两个日期输入。我有一个问题是让datepicker始终可见。知道怎么解决吗？

HTML

<input data-bind="datepicker: startDate, datepickerOptions: { minDate: new Date() }" />
<input data-bind="datepicker: endDate, datepickerOptions: { minDate: new Date() }" />

<hr />

<button data-bind="click: setToCurrentDate">Set To Current Date</button>

<hr />

<div data-bind="text: myDate"></div>

JS

ko.bindingHandlers.datepicker = {
    init: function(element, valueAccessor, allBindingsAccessor) {
        var $el = $(element);

        //initialize datepicker with some optional options
        var options = allBindingsAccessor().datepickerOptions || {};
        $el.datepicker(options);

        //handle the field changing
        ko.utils.registerEventHandler(element, "change", function() {
            var observable = valueAccessor();
            observable($el.datepicker("getDate"));
        });

        //handle disposal (if KO removes by the template binding)
        ko.utils.domNodeDisposal.addDisposeCallback(element, function() {
            $el.datepicker("destroy");
        });

    },
    update: function(element, valueAccessor) {
        var value = ko.utils.unwrapObservable(valueAccessor()),
            $el = $(element),
            current = $el.datepicker("getDate");

        if (value - current !== 0) {
            $el.datepicker("setDate", value);   
        }
    }
};

var viewModel = {
    startDate: ko.observable(new Date("12/01/2013")),
    endDate: ko.observable(new Date("12/01/2013")),
    setToCurrentDate: function() {
        this.startDate(new Date());
        this.endDate(new Date());
    }
};

ko.applyBindings(viewModel);

要使日期选择器始终可见，请将其绑定到<div>而不是<input />。

<div data-bind="datepicker: myDate, datepickerOptions: { minDate: new Date() }"></div>

Knockout datepicker始终可见
