Counting objects in a JSON string and splitting it in JavaScript without prior knowledge of the total number

My JSON structure contains multiple values like the following:

[{"Id":22,"Title":"München - Stockholm 31.01.2017 15:00"},{"Id":23,"Title":"Stockholm - München 01.02.2017 18:00"}]

I have successfully split one of them using this code:

var text = "[{\"Id\":22,\"Title\":\"München - Stockholm 31.01.2017 15:00\"}]";
console.log(JSON.parse(text)[0].Title.split(","));

How can I split all elements within the JSON structure?

The approach below works for 2 items, but I want a dynamic solution.

var text = "[{\"Id\":22,\"Title\":\"München - Stockholm 31.01.2017 15:00\"},{\"Id\":23,\"Title\":\"Stockholm - München 01.02.2017 18:00\"}]";

var count = Object.keys(text).length;
console.log(count);

for (var i=0; i < 2; i++){
    console.log(JSON.parse(text)[i].Title.split(","));
}

I tried to use the count variable in the loop, but it gave unexpected results. Any ideas on how to achieve this?

Thank you for your help!

Answer №1

To begin with, it's important to utilize the JSON.parse function:

var data = "[{\"Name\":\"John\",\"Age\":30},{\"Name\":\"Alice\",\"Age\":25}]"
var parsedData = JSON.parse(data)
var length = parsedData.length

console.log(length)

Remember that when dealing with arrays and objects, you need to work with actual arrays and objects. A string may appear like an array, but it consists of individual characters.
