javascript - 时刻 js 的无效日期

Question

考虑到这一点 http://jsfiddle.net/2a0hsj4z/4/ ，这里作为一个片段:

moment.locale("en");

var start = moment("2010-10", "YYYY-MM");
var end = moment("2017-10", "YYYY-MM");

$("#chord_range").ionRangeSlider({
    type: "double",
    grid: true,
    min: start.format("x"),
    max: end.format("x"),
    from: start.format("x"),
    to: end.format("x"),
    prettify: function (num) {
        return moment(num, 'x').format("MMMM YYYY");
    }
});

var slider = $("#chord_range").data("ionRangeSlider");

$(".irs-slider").click(function() {
	console.log(slider.result.from);
})

<link href="http://ionden.com/a/plugins/ion.rangeSlider/static/css/ion.rangeSlider.css" rel="stylesheet"/>
<input id="chord_range" />
<script src="http://code.jquery.com/jquery-1.11.0.js"></script>
<script src="http://ionden.com/a/plugins/ion.rangeSlider/static/js/ion-rangeSlider/ion.rangeSlider.js"></script>
<script src="http://momentjs.com/downloads/moment.min.js"></script>

当我尝试拖动左/右 slider (开始/结束值)时，为什么会出现无效日期错误？启动时日期显示正确。当您触摸 slider 时，它会断开。当我将 var start = moment("2010-10", "YYYY-MM"); 替换为 var start = moment("2012-10", "YYYY-MM"); 有效:

moment.locale("en");

var start = moment("2012-10", "YYYY-MM");
var end = moment("2017-10", "YYYY-MM");

$("#chord_range").ionRangeSlider({
    type: "double",
    grid: true,
    min: start.format("x"),
    max: end.format("x"),
    from: start.format("x"),
    to: end.format("x"),
    prettify: function (num) {
        return moment(num, 'x').format("MMMM YYYY");
    }
});

var slider = $("#chord_range").data("ionRangeSlider");

$(".irs-slider").click(function() {
	console.log(slider.result.from);
})

这是为什么？

Answer 1

您错过了step 选项，step 将为 1，1 对于 (option.max - option.min) 来说太小了，会导致 ion rangeSlider 出错。因此您应该设置一个较大的数字用于步骤选项。

$("#chord_range").ionRangeSlider({
    type: "double",
    grid: true,
    min: start.format("x"),
    max: end.format("x"),
    from: start.format("x"),
    to: end.format("x"),
    step: 100000,
    prettify: function (num) {
      return moment(num, 'x').format("MMMM YYYY");
    }
});
