Convert a string made from array toString() back to Array

Question

I converted an array to a string and added it to a TextArea. The user edited the TextArea and I need to now update the array by calling in the same string of data I first produced. How would you do this?

The string which I have produced and need to convert back to an array is:

{"color":"red","x":218,"y":-11,"width":60,"height":60},{"color":"blue","cx":114,"cy":83,"radius":30}

I tried to use the JSON Parser JSON.parse(text)

If you had used text = JSON.stringify(array) originally then you wouldn't need the workaround (you would be able to simply do JSON.parse(text)) — Jonathan Gray

Format your string:

const text = '{"color":"red","x":218,"y":-11,"width":60,"height":60},{"color":"blue","cx":114,"cy":83,"radius":30}'

console.log(JSON.parse(`[ ${text}]`))

You just need to format your string as an array in JSON format. You can do that like so:

JSON.parse('[' + text + ']')

The Below code should work:

var text_string = '{"color":"red","x":218,"y":-11,"width":60,"height":60},{"color":"blue","cx":114,"cy":83,"radius":30}';
console.log(JSON.parse(`[${text_string}]`));
