I have a response from an API (actually is a composite message from AWS lex) and it look like this:
'{\"messages\":[{\"type\":\"PlainText\",\"group\":1,\"value\":\"Great!\"},{\"type\":\"PlainText\",\"group\":2,\"value\":\"Please click here.\"}]}'
I can't change the response to a string, and I need to get from that string the text of:
"Great!" and "Please click here."
Basically anything after => "value\":\" and before \"}
I have tried plenty of approaches but couldn't hit the nail. Is there any way to do this, I even tried writing a regex but what I could get was the string before and not the actual text I need.
We can use JSON.parse to convert your JSON API output to a JS object. Then, we can iterate all messages in the array and extract the values.
var input = '{\"messages\":[{\"type\":\"PlainText\",\"group\":1,\"value\":\"Great!\"},{\"type\":\"PlainText\",\"group\":2,\"value\":\"Please click here.\"}]}';
var x = JSON.parse(input);
var arr = x.messages.map(item => item.value)
console.log(arr);Why won't you just use JSON.parse()?
const responseJson = '{"messages":[{"type":"PlainText","group":1,"value":"Great!"},{"type":"PlainText","group":2,"value":"Please click here."}]}';
const response = JSON.parse(responseJson);
const values = response.messages.map(message => message.value);
// values is now ['Great!', 'Please click here.']
