Converting data to JSON format and representing a number as a string

Question

Converting data to JSON format and representing a number as a string

Is there an easy solution to handle this specific situation

var data = {
     "phone":  input
}
var payload = JSON.stringify(data);

When the payload is utilized in an API call and the API specifically requires the phone value to be a string, despite phone numbers being accepted as either numbers or strings e.g. 123777777 or 1237-77777 etc

I attempted to use quotes, but JSON.stringify escapes them resulting in them becoming part of the final data.

The 'trick' I discovered was to add an extra space at the end i.e.

var data = {
     "phone":  input + " "
}

However, I am curious if there exists a straightforward and tidy way to handle this particular scenario?

Answer №1

When it comes to strings, they can actually be empty, as demonstrated by the following examples:

var data = {
    "phone": input + ""
};

Another approach that would achieve the same result is using "" + input. However, I prefer using the String function in this scenario:

var data = {
    "phone": String(input)
};

Important: Avoid using new String(...), stick with just String(...).

Using the input.toString() method suggested by others is also a valid option, as long as you are certain that input will not be either null or undefined. (If it is indeed null or undefined, it will result in an error.)

To ensure that a number is treated as a string, you can use the toString() method.

var data = {
  "phone": input.toString()
}

The great thing about this approach is that it won't throw an error even if the value is already a string. It will always result in a string. For more information, check out: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toString

Utilize the toString() method at all times, as it is effective regardless of whether the input is already a string.

var userData = {
     "phoneNumber":  userInput.toString()
}
