I am trying to call a method by passing in the id of the node but it keeps saying that method is not a function.
Here is the stackblitz link: https://stackblitz.com/edit/cytoscape-call-method?file=src/app/app.component.ts
You can click on any node and see the console error. It says this.showId is not a function.
Some code
this.cy.on('click', 'node', function(evt) {
console.log('clicked ' + this.id());
this.showId(this.id());
});
I have tried using tap as well but it still gives the same error.
Hm I think I see what you mean. It's about scopes in JS. Try below
this.cy.on('click', 'node', (evt) => {
console.log('clicked ' + this.id());
this.showId(this.id());
});
or below
this.cy.on('click', 'node', function (evt) {
console.log('clicked ' + this.id());
this.showId(this.id());
}.bind(this));
Both are actually the same
