I have a return from a javascript function that looks like this:
return{"success": true, "message": "Password changed."};
How do i retrieve these when calling this funciton?

2It's returning an object. You use the normal syntax for accessing properties of an object.Barmar– Barmar2015-01-31 11:30:49 +00:00Commented Jan 31, 2015 at 11:30

You are returning an Object, You can save it in a variable and then can access the object properties.
//function definition
function fun1(){
return{"success": true, "message": "Password changed."};
}
//function calling
var res1 = fun1();
//using the result returned by function call
if(res1.success)//true
{
alert(res1.message);//"Password changed.
}

It's just an object. Just access the properties.
var obj = foo();
for(var key in obj)
console.log(key, " = ", obj[key]);
You can also use just obj.success and obj.message to return the subsequent value.

That's not "multiple returns"; that's returning an object with properties. So the calling code receives an object, and then uses its properties:
var a = theFunction();
console.log(a.success);
console.log(a.message);

function functionReturningObject(){
return{"success": true, "message": "Password changed."};
}
// use a temporary variable!!! this is a valid syntax but will execute twice
// success = functionReturningObject().success
// message = functionReturningObject().message
var map = functionReturningObject();
// when you know it contents you refer it directly
console.log(map.success)
console.log(map.message)
// when you do not know it contents, you can "explore" it
Object.keys(map).forEach(function(key){console.log(key);console.log(map[key]);})
