JavaScript Print name of Javascript object contained in array print name javascript,print variable name javascript,print function name

example1 is a reference to your Location object, and JavaScript has no concept of doing what you want to do.

If you really need the name, I would store it on your object.

Answer:1

Objects don't have any back-reference to the variables that refer to them. Consider this:

var example1 = new Location(...);
var example2 = example1;

Now there's one location named by two variables, which would you expect the "name" to be?

Answer:2

May I suggest that rather storing the set of locations as an array, you store it as an object. You appear to be trying to store the name of a city in combination with the location data.

You could use a data structure like this for cities:

var cities = {
    "london": example1,
    "lisbon": example2
}

You can then do:

cities.london.name

You have to add return this to the end of your Location function definition.

Answer:3

You can't do what you want. Objects in JavaScript are generally used by reference rather than by value. So for, example, if you used:

var ex1 = new Location();
var ex2 = ex1;
var ex3 = ex1;

Then all three of those variables (ex1, ex2, and ex3) are referring to the exact same object. There's no way that the object could pick one even if the language tried to permit it.

Answer:4

You could store the objects in another dynamic object, and then use the "variable name" as the key, but I'm not 100% sure that that buys you much. The approach would be:

var examples = {};
examples["example1"] = new Location('value', 'value', etc);
examples["example2"] = etc etc

At that point, you would be able to access the key associated with the current object. The thing is, you would have to have access to the key in order to get to the object, so, like I said, I'm not sure how much it buys you . . .

Note: Chris Alexander and Jay are suggesting similar approaches . . .
