嵌套的foreach在knockout.js

Question

我似乎无法让嵌套的foreach工作.

JS代码是:

$(document).ready(function() {

    function chartValueViewModel(date, price) {
        this.date = date;
        this.price = price;
    }

    function chartViewModel(id, name, lineType, values) {
        this.id = id;
        this.name = name;
        this.lineType = lineType;
        this.values = ko.observableArray(values);
    }

    function liveCurveViewModel() {

        this.chartsData = ko.observableArray([]);
        var chartsData = this.chartsData;

        this.init = function() {

            var mappedCharts = $.map(chartValues,
            function(chart) {
                var mappedValues = $.map(chart.chartValues, function(value) {
                    return new chartValueViewModel(value.dateTime, value.price);
                })
                return new chartViewModel(chart.id, chart.name, chart.liveCurveTypeId, mappedValues);
            });

            chartsData(mappedCharts);
        };
    }

    var vm = new liveCurveViewModel();
    vm.init();
    ko.applyBindings(vm);

});

Html是:

<ul data-bind="foreach: chartsData ">
    <li data-bind="text: name">
        <ul data-bind="foreach: values">
           <li data-bind="text: price">
           </li>
        </ul>
    </li>
</ul>

外部循环正确呈现,但我从内部循环中得不到任何内容,甚至没有错误消息.我已经检查过了,并且填充了chartViewModel上的values字段.

text你在外面的绑定li正在覆盖它内部的内容,所以它正在吹走你的内心foreach.的text结合套的innerText /的textContent元件的,其覆盖当前的儿童.

您可能想要做类似的事情:

<ul data-bind="foreach: chartsData ">
    <li>
        <span data-bind="text: name"></span>
        <ul data-bind="foreach: values">
           <li data-bind="text: price">
           </li>
        </ul>
    </li>
</ul>
