javascript - 将由数组 toString() 生成的字符串转换回数组

Question

我将数组转换为字符串并将其添加到 TextArea。用户编辑了 TextArea，我现在需要通过调用我最初生成的相同数据字符串来更新数组。你会怎么做？

我生成并需要转换回数组的字符串是:

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

我尝试使用 JSON 解析器 JSON.parse(text)

Answer 1

格式化你的字符串:

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}]`))
