如何将包含等号的字符串解析为对象

Question

I have a string variable

let stringValue = "{DATA={VERSION=1.1, STATE=true, STATUS=ONLINE}}"

I would like to parse it to object as result where result will be:

let result = {"DATA":{"VERSION":1.1, "STATE": true, "STATUS": "ONLINE"}}

How would you convert a stringValue to result object so it would be possible to access the nested keys?

console.log(result.DATA.STATUS)

Answer 1

Under the assumption that keys and string values are fully capitalized:

• I used the regex /[AZ]+/g and .match(regex) to get an array of every all caps word in the string.

• Create a Set out of the the array to remove duplicates and avoid repeating the next step on the same string multiple times.

• Then iterate over each word and replace it in the main string with itself between quotes. DATA => "DATA"

• Then replace = with :

• And finally JSON.prase() and we get the object.

 let stringValue = "{DATA={VERSION=1.1, STATE=true, STATUS=ONLINE}}"; let regex = /[AZ]+/g let objectStrings = stringValue.match(regex) let uniqueStrings = [... new Set(objectStrings)] uniqueStrings.forEach((string) => stringValue = stringValue.replaceAll(string, '"'+string+'"')); stringValue = stringValue.replaceAll('=', ':'); console.log(JSON.parse(stringValue))

Here it is in JSBin to show that the keys are properly assigned without the quotes.
