Javascript 按标题键筛选数组对象

我试图通过过滤“页面标题”键来获取每个数据。 这是我的示例json对象

{
"page_components": [
  {
    "page_title": "My Account",
    "row_block": [
      {
        "heading": "",

          "filename": "Home-Loans-Sushi-Train.png",
          "url": "Home-Loans-Sushi-Train.png"
        },
        "show_gold_icon_list": false,
        "show_blue_icon_list": false,

      },

    ]
  }
]
}

我想通过过滤页面标题来获得每一行块。目前我有这个代码，它似乎不工作。我不知道如何通过函数传递给定标题的每一行

getPageComponents(title: string) {
 this.pageComponents.filter((page) => {
   return page.page_title === title;
 });
}

但我没能得到结果。有人能帮我在javascript中使用过滤器吗。提前感谢

您缺少

return

关键字

getPageComponents(title: string) {
 return  this.pageComponents.filter((page) => {
   return page.page_title === title;
 });
}

我对打字本一点也不熟悉，但这不重要

.filter

不作用于阵列。。。它返回一个新数组。尝试将某个值设置为this.pageComponents.filter或将其返回。是否检查了标题参数数据？是否缺少

return

keyword@MdMahamudulHasan是的，我已经检查过了。@Phong Omg。我想它现在起作用了。帮个大忙！！！太棒了
