I'am have:
interface Intfff
{
csv: {
(url: string);
parsess(lol: string);
};
}
class Class implements Intfff
{
csv(url: string) {
}
}
var obj: Intfff = new Class();
obj.csv('sdfsdf');
obj.csv.parsess('sdf');
How do I implement a method csv.parsess() ? translator typeScript an error on Class: missing property 'parsess' from type ...
Help me understand
Why not try this instead?
interface Intfff
{
csv(url: string): Intfff;
parsess(lol:string):string;
}
class TestClass implements Intfff
{
csv(url: string) {
return this;
}
parsess(lol: string) {
return "Hello";
}
}
var obj: Intfff = new TestClass();
obj.csv('sdfsdf').parsess('sdf');
You can't fullfill that interface with a class method. You will have to define the function as type any, and add the missing member, before adding it to the object.
interface Intfff
{
csv: {
(url: string);
parsess(lol: string);
};
}
class Test implements Intfff {
public csv : { (url: string); parsess(lol: string); };
constructor() {
var csv : any = function (url: string) {
// ...
};
csv.parsess = function (lol: string) {
// ...
};
this.csv = csv;
}
}
