Tips for showing just the value, not the key, following JSON.stringify:

I'm facing an issue where I need to extract the value of a specific key from a JSON object obtained after using JSON.stringify on form data. The current JSON object that I have looks like this:

{"KEY":"KM8IJM12D56U303366"}

Here's the code snippet I am using to retrieve and display this value:

const onSubmit = async data => {

    // How can I specifically extract data from the stringified JSON
    var jsonString = JSON.stringify(data, ["KEY"]);
    alert(jsonString);
    notify();
};

I attempted using getItem() but it seems to only be effective with local storage. Is there any alternative solution that would allow me to directly access the value of KEY post JSON.stringify()?

Answer №1

For accessing keys and values, you will have to use the JSON.parse() method to convert it back into an object. Once you've utilized the stringify() function, the data becomes a string.

Hey there, I highly recommend using the data as an Object instead of converting it to a string.

const onSubmit = async data => {

    // If data is not already a Stringified Object:
    var jsonString = JSON.stringify(data.key);
    alert(jsonString);
    notify();

    //********

    // If data is already a Stringified Object:
    var jsonString = JSON.parse(data);
    alert(jsonString.key);
    notify();
    
};

However, if you prefer to work with strings:

const onSubmit = async data => {
    // If you only need the Key as a string, use the following line
    var jsonString = data.key.toString();

    // Otherwise, access your key directly like so
    var jsonString = data.key;

    alert(jsonString);
    notify();
};
