我在瀏覽器中使用控制臺來使用 JS 抓取和排序內容。這是我的代碼
這是我的結果陣列
var arr = [
"George\nPresident & Founder",
"content",
"Ronald\nCountry Director, America",
"content",
"Kriss, PhD\nVice President",
"content",
"Joseph, MS\nDirector",
"content",
"Elizabeth\nDevelopment Operations",
"content",
"Lisa, MFA, MBA\nU.S. Content",
"content.",
"Natalia\nCountry Director"
]
這是我嘗試過的：
for(var i=0; len = result.length, i < len; i ){
result[i]['something'] = [];
if(i === 0){
result[i].split('\n');
}
else if (i % 2 === 0) {
result[i].split('\n');
}
console.log(result[i]);
result[i]['test'].push(result[i]);
}
回傳結果為 result[i]['something'] = []; 未定義但是當我 console.log(result[i]) 我得到正確的結果。我試過復制(JSON.stringify(result[i])) 但我只取回一個物件。
for(var i=0; len = result.length, i < len; i ){
var arr = [];
if(i === 0){
result[i].split('\n');
}
else if (i % 2 === 0) {
result[i].split('\n')
}
arr.push(result[i])
// console.log(result[i]);
console.log(arr);
}
這不會拆分它們，它只是將它們推入陣列。
當我 console.log(result[i]) 我得到：（這是正確的，但它不在字串中，也不在陣列中；我也無法復制它）
George
President & Founder
content
Ronald
Country Director America
content
Kriss PhD
Vice President
content
Joseph MS
Director
content
Elizabeth
Development Operations
content
Lisa MFA MBA
U.S. Content
content
Natalia
Country Director
我的最終目標應該是這樣的：
var result = [
["George"],
["President & Founder"],
[ "content" ],
[ "Ronald"]
["Country Director, America" ],
[ "content" ],
[ "Kriss, PhD"],
["Vice President" ],
[ "content" ],
[ "Joseph, MS"],
["Director" ],
[ "content" ],
[ "Elizabeth"],
["Development Operations" ],
[ "content" ],
[ "Lisa, MFA, MBA"],
["U.S. Content" ],
[ "content." ],
[ "Natalia"],
["Country Director" ],
[ "content." ]
]
我該怎么做才能得到結果 [i] 并使用 copy(JSON.stringify(result)) 將其復制到剪貼板上？

我會生成一個物件陣列。由于每個人在陣列中有兩行（除了 Natalia，她沒有內容？），您可以遍歷陣列，一次跳躍兩行，將每個人的資訊收集到一個物件中。
var arr = [
"George\nPresident & Founder",
"content",
"Ronald\nCountry Director, America",
"content",
"Kriss, PhD\nVice President",
"content",
"Joseph, MS\nDirector",
"content",
"Elizabeth\nDevelopment Operations",
"content",
"Lisa, MFA, MBA\nU.S. Content",
"content.",
"Natalia\nCountry Director"
];
const result = [];
for (let i=0; i < arr.length; i =2) {
const nameParts = arr[i].split("\n");
result.push({
name: nameParts[0],
title: nameParts[1],
content: arr[i 1]
});
}
console.log(result);uj5u.com熱心網友回復：
其他答案似乎很有趣。我會建議一個稍長的，有幾個 for 回圈。
這就是我想出的：
更新：我已經更新了它，現在你也更新了你的帖子。
function changeArr(array) {
// create a temporary array
let tempArr = [];
// loop through the array which was passed as an argument
for (let i = 0; i < array.length; i ) {
let splitArr = array[i].split("\n");
// splitArr returns an array containing the 2 strings which have been split
// using the spread operator from ES6 we can spread out the elements and push them into tempArr
tempArr.push(...splitArr);
}
// tempArr should now contain your end result
return tempArr;
}
如何使用：
changeArr(arr);
/*
this will return:
=> [
"George",
"President & Founder",
"content",
"Ronald",
"Country Director, America",
"content",
"Kriss, PhD",
"Vice President",
"content",
"Joseph, MS",
"Director",
"content",
"Elizabeth",
"Development Operations",
"content",
"Lisa, MFA, MBA",
"U.S. Content",
"content",
"Natalia",
"Country Director",
"content"
]
有了這個，您可以呼叫另一個變數let result并將函式回傳的任何內容存盤在其中。
let result = changeArr(arr);
或者您可以將函式回傳的任何內容分配給arr變數。
arr = changeArr(arr);

洗掉 arr.push(result[i]) 并嘗試這個
if (i % 2 == 0) {
arr.push( result[i].split('\n'));
}
else
{
arr.push(["content"]);
}
uj5u.com熱心網友回復：
您可以通過使用reduce更容易的方法來實作您的目標：
let arr = [
"George\nPresident & Founder",
"content",
"Ronald\nCountry Director, America",
"content",
"Kriss, PhD\nVice President",
"content",
"Joseph, MS\nDirector",
"content",
"Elizabeth\nDevelopment Operations",
"content",
"Lisa, MFA, MBA\nU.S. Content",
"content.",
"Natalia\nCountry Director"
]
let result = arr.reduce((acc, str) => {
str.split('\n').forEach(str => acc.push([str]));
return acc;
}, [])
