I'm struggling to log the name value on a click event. Can you please provide some guidance? This is inside the .ts file:
export class ScrolldemoComponent implements OnInit {
constructor() { }
ngOnInit() {
const name = "test";
}
myEvent(event) {
console.log(name);
}
}
This is inside the HTML:
<button (click)="myEvent()">My Button</button>
Implement it within the component's scope
title:string = 'example'
ngOnChanges() {
this.title = "changed";
}
triggerEvent(event) {
console.log(this.title);
}
When using the "const" keyword, variables are block-scoped meaning they only exist within the innermost block they are declared in.
Therefore, if you declare a variable inside a function like "ngOnInit", you will not be able to access it outside of that function. It is recommended to define such variables at the component level as advised by Aravind.
To ensure easy access to a variable across different functions, it is advisable to create a global variable and initialize its value within the ngOnInit lifecycle hook. It's important to note that const, let, and var are all block-specific types of variables. For further guidance on this topic, you can review Aravind's example code where he opted to utilize a global function instead of a block-specific variable.
