I would like to replace a json string from:
[{"id":151,"name":"me"}, {"id":4567432,"name":"you"}]
to:
[{"id":"151","name":"me"}, {"id":"4567432","name":"you"}]
As you can see, I just want to add parentheses to the id's value(some number).
I tried:
json = json.replaceAll("\"id\",([0-9]+)", "\"id\",\"$1\"");
but it doesn't work. How can I do it?
You are using commas as key-value separator, but in the sample string, you have a colon.
You can fix the replaceAll method if you use
replaceAll("(\"id\":)([0-9]+)", "$1\"$2\"")
See the online regex demo.
Details:
(\"id\":) - Group 1 ($1): "id": string([0-9]+) - Group 2 ($2): one or more digits
with js code
// #js code
const data = [{"id":151,"name":"me"}, {"id":4567432,"name":"you"}];
function solve1(data) {
// solution 1
// with stringify data
const getMatches = data.match(/\"id\"\:\d+\,/gi);
getMatches?.forEach((theMatch)=>{
const getNumbers = theMatch.match(/\d+/gi).join("");
const newMatch = theMatch.replace(getNumbers,`"${getNumbers}"`);
data = data.replace(theMatch,newMatch)
})
return data;
}
function solve2(data) {
// solution 2
// with json data
return data.map((item)=>{
item.id = item.id.toString();
return item;
})
}
console.log(solve1(JSON.stringify(data)));
console.log(solve2(data))
