Question

我有一个项目列表，我需要做的是能够检查该列表项中的复选框，然后才能启用该列表项中的复选框。这是我到目前为止所做的JSFiddle。这将启用页面上具有该类名称的所有复选框。因为这来自数据源是一个JS文件，这些列表项是在kendo模板中生成的，所以我需要带有类名的文本框。

谢谢

<ul id="productsFoundList" data-role="listview" data-style="inset" class="km-list" data-bind="source:foundProducts" data-template="productsFound-listview-filtering-template">

尝试

var $basket = $("#basketButton");
var $checks = $(".productsUl").change(function () { //for each checkbox
    $(this).next().find(".productsFoundInputBorders").prop('disabled', !this.checked);
    $basket.stop(true, true)[$checks.filter(':checked').length  == 0 ? 'hide' : 'show'](500)
});

当在列表项中选中复选框时，仅启用该列表项中的文本框 - 按类Jquery
