存储记录内的筛选数组

Filtering Array within a store record

本文关键字：筛选 数组 记录 存储      更新时间：2023-09-26

我在一个存储中有一个JSON对象，如下所示。我是根据属性网格中的选择动态过滤值。我不是过滤的顶层值(personName, primaryRole等)，而是我想钻到我有周期的数组。例如，我想过滤存储中的"periods">"periodName"的每条记录。

我不知道该怎么做，因为我以前没有遇到过这种情况。使用combo.getStore().filter('periodName', gridvalues.periodName);不起作用，因为它找不到periodName，而且我不能简单地使用句点。periodName不幸。

"id": "531b0633-c9f5-4cbe-be69-5df4944b6e9b",
        "personName": "Ben",
        "primaryRole": "SWE",
        "secondaryRole": "SWE",
        "periods": [
            {
                "personName": "Ben",
                "periodName": "Week 24",
                "teamName": "Tango",
                "experience": 2,
                "periodNumber": 24,
                "id": "71d514c2-a39f-40b7-af9e-51fbf30b2a48"
            },
            {
                "personName": "Ben",
                "periodName": "Week 25",
                "teamName": "-",
                "experience": "-",
                "periodNumber": 25,
                "id": "49505fb2-97df-4f45-a11d-bb22c110a422"
            },
            {
                "personName": "Ben",
                "periodName": "Week 26",
                "teamName": "-",
                "experience": "-",
                "periodNumber": 26,
                "id": "97f2b272-c23c-4320-a1ce-09dadf0c6b5d"
            },
"id": "7037ad16-dcbe-4326-8547-65108c03c874",
        "personName": "Luke",
        "primaryRole": "Product Owner",
        "secondaryRole": "SWE",
        "periods": [
            {
                "personName": "Luke",
                "periodName": "Week 24",
                "teamName": "Tango",
                "experience": 3,
                "periodNumber": 24,
                "id": "e3184bef-c330-4219-ae21-8b65efcde77c"
            },
            {
                "personName": "Luke",
                "periodName": "Week 25",
                "teamName": "-",
                "experience": "-",
                "periodNumber": 25,
                "id": "f431af7b-8060-40d2-8464-af533d943363"
            },

这是来自我的商店的记录:

在控制器中使用addFilter功能:

combo.getStore().addFilter({property: 'yourProperty', value: 'valueToFilter'});
