Is there way to add setter to object dynamically like this?
output = document.querySelector(".output")
log = (out)=>{
output.innerHTML = out
}
class A {
constructor(some){
this._some = some
}
}
myObj = new A(1)
// myObj = Add setter there...<div class="output"></div> I just need this to write classes which instaces can dynamically create setters to their properties.
You can do it like this:
class A {
constructor(some){
this[some] = some // This needs to be a string, otherwise it doesn't work
}
}
If you need to do more complex stuff you can do something like:
const exampleInput = {
prop1: 123,
prop2: "someString"
}
class A {
// Make some an object like the one above
constructor(some){
for (prop in some) {
this[prop] = some[prop]
}
}
}
Is this what you want?
class A {
constructor(some){
this._some = some
}
}
let myObj = new A(1)
console.log(myObj._some) // 1
Object.defineProperty(myObj, 'setSome', {
set: function(x) { this._some = x ; }
});
myObj.setSome = 77;
console.log(myObj._some) // 77
