想法是每個過濾的物件都由一個陣列包裝，所以我嘗試了這個：
const linkMessage = groupedMessages.flatMap((arrMessage) => arrMessage).some((message) => isValidURL(message.content));
const embedMessage = groupedMessages.flatMap((arrMessage) => arrMessage).some((message) => message.embeds.length > 0 && message.embeds.map((emb) => emb.type === 'rich'));
const componentMessage = groupedMessages.flatMap((arrMessage) => arrMessage).some((message) => message.components.length > 0);
const responseField = [];
if (linkMessage) {
responseField.push(
groupedMessages.map(
(arrMessage) =>
`from ${userMention(arrMessage[0].author.id)}\n${arrMessage
.filter((message) => isValidURL(message.content))
.map((message) => `${message.content} (sent at ${time(new Date(message.createdTimestamp), TimestampStyles.RelativeTime)})\n`)
.join('')}`,
),
);
}
if (embedMessage || componentMessage) {
responseField.push(groupedMessages.map((arrMessage) => `from ${userMention(arrMessage[0].author.id)}\n${italic('No content, maybe an embed or a component.')}`));
}
但預期的輸出與我想要的不同。我只想創建一個嵌套陣列格式。誰能幫我？
編輯
我簡化了案例：
[
[
{
"id": "1",
"content": "https://youtube.com",
"authorId": "1",
"embeds": [...
]
},
{
"id": "2",
"content": "lorem ipsum.",
"authorId": "1",
"embeds": []
},
{
"id": "3",
"content": "",
"authorId": "1",
"embeds": []
}
],
[
{
"id": "1",
"content": "https://whatsapp.com",
"authorId": "2",
"embeds": [...
]
},
{
"id": "2",
"content": "lorem ipsum.",
"authorId": "2",
"embeds": []
},
{
"id": "3",
"content": "",
"authorId": "2",
"embeds": []
}
]
]
預期輸出：
[
[
// Link type messages (content is valid URL)
[
{
"id": "1",
"content": "https://youtube.com",
"authorId": "1",
"embeds": [
{
"type": "link"
}
]
}
],
// regular type messages (empty embeds data)
[
{
"id": "2",
"content": "lorem ipsum.",
"authorId": "1",
"embeds": []
}
],
// Embed type messages (empty content)
[
{
"id": "3",
"content": "",
"authorId": "1",
"embeds": [
{
"type": "rich"
}
]
}
]
],
[...
]
]
uj5u.com熱心網友回復：
您想用陣列包裝每個元素。讓我們“遞回地”迭代陣列（實際上只是兩個級別）尋找陣列，直到我們找到一個非陣列，然后我們將它包裝并放置在arr[index].
更新：
- 不需要遞回，因為它是一個已知的結構
- 我們按型別（“Link”、“Regular”或“Empty”）將子陣列項分組到物件中
- 最后我們將該物件的值作為所需的陣列
- 就地更新父陣列
