I have following code
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<{name: string, empoloyeeID: number}> = [];
constructor() {
}
ngOnInit() {
}
onEmpCreate(){
console.log(this.name,this.empoloyeeID);
this.empList.push.apply(this.name,this.empoloyeeID);
this.name ="";
this.empoloyeeID = 0;
}
}
but this throwing error
CreateListFromArrayLike called on non-object
Also is there any way to create a custom class and used object list rather than defining array over here.
Thanks
This question is related to
angular
typescript
Yes there is a way to do it.
First declare a class.
//anyfile.ts
export class Custom
{
name: string,
empoloyeeID: number
}
Then in your component import the class
import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<Custom> = [];
constructor() {
}
ngOnInit() {
}
onEmpCreate(){
//console.log(this.name,this.empoloyeeID);
let customObj = new Custom();
customObj.name = "something";
customObj.employeeId = 12;
this.empList.push(customObj);
this.name ="";
this.empoloyeeID = 0;
}
}
Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html
Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2
Your empList is object type but you are trying to push strings
Try this
this.empList.push({this.name,this.empoloyeeID});
Push object into your array. Try this:
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<{name: string, empoloyeeID: number}> = [];
constructor() {}
ngOnInit() {}
onEmpCreate(){
console.log(this.name,this.empoloyeeID);
this.empList.push({ name: this.name, empoloyeeID: this.empoloyeeID });
this.name = "";
this.empoloyeeID = 0;
}
}
