I have such variable declaration in my JavaScript method on :
var MyVariable = {
CarMake: "Lexus",
CarColor: "Black"
}
What I am trying to accomplish is to add some login within MyVariable declaration such as:
var MyVariable = {
CarMake: "Lexus",
if (carType == "sedan") {
NumberOfDoors: 4,
}
CarColor: "Black"
}
Is this possible somehow?
With a one-line object you can't do it. You need to assign it later. But I thnik you can create a class(ES6) and use like
class Car{
constructor(maker, color, type){
this.maker = maker;
this.color = color;
if(type === 'sedan'){
this.numberOfDoors = 4;
}
}
}
var car = new Car('Lexus','Black','sedan');
console.log(car.numberOfDoors);Or use the function syntax
function Car(maker, color, type){
this.maker = maker;
this.color = color;
if(type === 'sedan'){
this.numberOfDoors = 4;
}
}
var car = new Car('Lexus','Black','sedan');
console.log(car.numberOfDoors);I suppose you could do
var MyVariable = {
CarMake: "Lexus",
CarColor: "Black",
NumberOfDoors: (carType === 'sedan') ? 4 : undefined
}
which is not exactly the same, but close.
But how about
var MyVariable = {
CarMake: "Lexus",
CarColor: "Black"
}
if (carType === 'sedan') {
MyVariable.NumberOfDoors = 4
}
You could wrap this into a "factory" function and then do
var MyVariable = makeCar("Lexus", "Black", "sedan")
One way you could do this:
var MyVariable = {
CarMake: "Lexus",
CarColor: "Black"
}
if (carType == "sedan") {
MyVariable.NumberOfDoors = 4;
}
You need to create your variable before and add the new attribute after :
var MyVariable = {
CarMake: "Lexus",
CarColor: "Black"
}
if (carType == "sedan") {
MyVariable.NumberOfDoors = 4
}
