无法在 JavaScript 中删除数组中的对象

Question

我一直在尝试从数组中删除具有特定值的对象，所有代码和语法似乎都失败了，即使是我在这个平台上复制的那些。

// UNABLE TO WRITE "DELETE" CAMPUS DIRECTOR CODE
router.delete("/:id/director", userAuth, checkRole(["admin"]), async(req, res) => {
    const campus = await Campus.findById(req.params.id);
    const campusAdmins = campus.admins
    // campusAdmin will return a single object in an array [{_id: 1234567865434543, title: "campus director", userId: "9876543456fdfgfdgf"}]
    try {
        campusAdmins.splice(campusAdmins.findIndex(e => e.title === "campus director"),1);
        console.log(campusAdmins);
        res.status(201).json("You've successfully delete campus director");
    } catch (err) {
        res.status(500).json(err);
    }
})

请帮我解决这个问题。

Answer 1

您确定campusAdmins 返回您在评论中指定的对象吗？

语法没有问题，这行得通：

const campusAdmins = [{
  _id: 1234567865434543,
  title: "campus director",
  userId: "9876543456fdfgfdgf"
}];

try {
  campusAdmins.splice(campusAdmins.findIndex(e => e.title === "campus director"), 1);
  console.log(campusAdmins);
  console.log("Successfully deleted campus director");
} catch (err) {
  console.log("Failure");
}
