On this page it is shown that a object can implement get and setters in javascript. But they use a different way to create an object than my code. How can i implement get and setters in the following code:
function Settings()
{
var fullscreen;
// get function
this.fullScreen = function ()
{
if(fullscreen === undefined)
{
return false
}
return fullscreen;
};
// set function
this.fullScreen = function (fullscrn)
{
fullscreen = fullscrn;
};
// I want to call the set like this: settingsobj.fullScreen = false;
// I want to call the get like this: var myvar = settingsobj.fullScreen;
}
You could take an object and implement setter/getter for a wanted property.
var object = {
fc: undefined,
get fullscreen () { return this.fc === undefined ? false : this.fc; },
set fullscreen (v) { this.fc = v; }
}
console.log(object.fullscreen);
object.fullscreen = 1080;
console.log(object.fullscreen);
With an instance and a provat variable and getter and setter for it.
class Settings {
constructor() {
var fc;
Object.defineProperty(this, 'fullscreen', {
get () { return fc === undefined ? false : fc; },
set (v) { fc = v; }
});
}
}
var instance = new Settings;
console.log(instance.fullscreen);
instance.fullscreen = 1080;
console.log(instance.fullscreen);
