如何更改数组的字符串元素并将更改后的版本推送到原始数组中？

  • 772

gridTemplateAreasArray我有一个由一个元素组成的初始数组。
该元素具有以下值：

'"sources auto" "clicks auto" "shows auto" "conversion-price auto" "price auto" "conversion auto" "sales auto"'

我需要通过 JS 重写这个数组，使它看起来像这样：

[
  '"sources auto" "clicks auto" "shows auto" "conversion-price auto" "price auto" "conversion auto" "sales auto"',
  '"sources_twin_1 auto" "clicks_twin_1 auto" "shows_twin_1 auto" "conversion-price_twin_1 auto" "price_twin_1 auto" "conversion_twin_1 auto" "sales_twin_1 auto"'
]

可用代码

const table = document.querySelector('.table'),
        tableArticles = document.querySelectorAll('.table__article');
  
const gridTemplateAreas = window.getComputedStyle(table).gridTemplateAreas;
const gridTemplateAreasArray = window.getComputedStyle(table).gridTemplateAreas.split();

我该怎么做？

javascript

    const arr = [`"sources auto" "clicks auto" "shows auto" "conversion-price auto" "price auto" "conversion auto" "sales auto"`]
arr[1] = arr[0].split(/"\s+"/g).map((i) => i.replace(/\s+/, '_twin_1 ')).join('" "')
console.log(arr)

    ！！！但前提是在短语的结尾总是 auto"

    const arr = [`"sources auto" "clicks auto" "shows auto" "conversion-price auto" "price auto" "conversion auto" "sales auto"`]
arr[1] = arr[0].replace(/(\s+auto")/, "_twin_1$1")
console.log(arr)
