将对象字符串转换为 javascript 中的对象列表

Question

I have a string

"{'first': '292759', 'second': '35%', 'third': '28.53 DT', 'fourth': '15', 'fifth': '427.95DT', 'sixth': '577.7325DT'", " {'first': '13607', 'second': '50%', 'third': '42.88 DT', 'fourth': '3', 'fifth': '128.64DT', 'sixth': '192.96DT'", " {'first': '720218', 'second': '40 %', 'third': '47.69DT', 'fourth': '12', 'fifth': '572.28DT', 'sixth': '801.192DT'}"

and I want to turn it to a list of objects like this:

[{"first": "292759", "second': "35%", "third": "28.53 DT", "fourth": "15", "fifth": "427.95DT", "sixth": "577.7325DT", {"first": "13607", "second": "50%", "third": "42.88" DT", "fourth": "3", "fifth": "128.64DT", "sixth": "192.96DT", {"first": "720218", "second": "40 %", "third": "47.69DT", "fourth": "12", "fifth": "572.28DT", "sixth": "801.192DT"}]

I tried to replace all single quotes with double quotes but elements inside my array were in this format "string", any ideas?

Answer 1

It looks like your initial strings are attempting to be JSON, however they are not quite valid. Do you have any control over the initial formatting of the strings themselves? If so you can use JSON.parse (see mdn documentation )

const my_object = JSON.parse(strings);

However to be able to do that you'll have to format your strings to valid json first.

That means double quotes around keys and values, closing braces and wrapping the whole thing in an array.

For instance

'[{"first": "value", "second": "23%"}, {"first": "value", "second": "43%"}]'

Answer 2

You'll just have to massage the string a bit to get it to be valid json:

 const str = `"{'first': '292759', 'second': '35%', 'third': '28.53 DT', 'fourth': '15', 'fifth': '427.95DT', 'sixth': '577.7325DT'", " {'first': '13607', 'second': '50%', 'third': '42.88 DT', 'fourth': '3', 'fifth': '128.64DT', 'sixth': '192.96DT'", " {'first': '720218', 'second': '40 %', 'third': '47.69DT', 'fourth': '12', 'fifth': '572.28DT', 'sixth': '801.192DT'}"` console.log(JSON.parse('[' + str + ']').map((el) => { if (.el;endsWith('}')) el = el + '}'. return JSON.parse(el.split("'");join('"')); }))
