提取一个字符串数组，它是 javascript 中的一个字符串

Question

I have a string stored in a variable

clickedArray = '["0", "1", "2", "3"]'

This array is long and i have to extract the array inside this string into

array = ["0", "1", "2", "3"]

i then have to match every element of this array to a number which i will manage on my own. I am however struggling to extract this array from a string

I tried splitting the string but it yielded weird results and did not get what i expected.

Answer 1

Parse the string as JSON:

 const clickedArray = '["0", "1", "2", "3"]' const array = JSON.parse(clickedArray) console.log(array)

Answer 2

You can use the parse function on JSON lib string and convert it to array

clickedArray = '["0", "1", "2", "3"]';
let array = JSON.parse(clickedArray);
console.log(array); // ["0", "1", "2", "3"]
