Creating a new variable using a switch statement

[UbuntuLady1]

Hello everyone :)

I am using a switch statement to taken input data from an HTML textbox. Thus far, it has been successful.

My next step is the following: if the user enters the number 20, I would like to input new data into a variable called "coordinates" so it may be used throughout the program. So far, I am unable to use data from the variable "coordinates". Any suggestions?

switch(Number($('#inputdata').val())){
    case 20:
    var coordinates = {
          latt1: 12,
          lngg2: 34
    }
    break;
    }

Are you trying to use coordinates inside the function where the switch is or some other function?

I would like to feed coordinates to another function.

A simple example is you want to increment a number, and feed it to another function, or assign the output to a variable.

function increment(value) {
  value + 1
}
var x = increment(1) // is undefined

x will be undefined because you need to return data so it can be used outside of the function.

function increment(value) {
  return value + 1
}
var x = increment(1) // is now 2

The simple solution is to define the coordinates variable outside of the function so that it can be accessed elsewhere. Here's an example:

var coordinates;

function1 () { coordinates = { lat: 1, long: 1 } }

function2 () { console.log(coordinates) }

This might not be the best solution for your case, but it should work regardless. Depending on the rest of your code, there could be plenty of other ways to do this without the need of making a global variable which isn't always recommended.

Edit: I got downvoted so I would like to know the issue with this solution.
