我的每个div包含多个复选框，我有几个div。我想跟踪选中哪个复选框及其各自的div。我试图将它存储在一个多维数组中，但它不合适.. 如果您有任何其他想法，那么请与我分享。

您可以尝试的一件事是将其存储为JSON对象。例如，假设div1，div2和div3各包含2个复选框。然后JSON对象将只包含已选中的复选框，如
var jsonObject = [{ "divName" : "div1", "selectedCheckBoxes" : [{"checkbox1"}] }, [{ "divName" : "div2", "selectedCheckBoxes" : [{"checkbox2"}] }]等等。
这个link可以帮助您理解JSON对象。

<强> DEMO ：
$(function() {
$('#myButton').click(function() {
$('input:checkbox:checked').each(function(i) {
alert(this.value);
var id= $(this).parent().attr('id')
alert(id);
});
});
});

一种方法是使用JSON存储。它有一个名为checked的事件，它返回一个布尔值。另外，请通过以下链接： http://docs.sencha.com/ext-js/3-4/#!/api/Ext.form.Checkbox-event-check
