Question

Issue with Vue Router: Hyperlinks within HTML5 Canvas images are not correctly redirecting to the intended URL

I'm working on a project to connect images on an HTML5 canvas to specific URLs for navigation within a website.

My tools include Vue, FabricJS for the canvas, and Vue-router for routing.

let computerClick = function (evt) {
  console.log("Computer clicked");
  this.$router.push('/app');
};

After clicking an item on the canvas, the above function is triggered, but I encounter this error:

Uncaught TypeError: Cannot read property 'push' of undefined

I would appreciate guidance on resolving this issue. Thank you!

javascript canvas vue.js fabricjs vue-router

Answer №1

When defining a function in this manner, the reference to this within the computerClick function does not point to the Vue instance and therefore results in being undefined.

It might be more appropriate to reconsider your code structure in order to avoid defining functions in this way. A better approach would be to make computerClick a component method (which can then be called using this.computerClick()):

methods: {
  computerClick() {
    console.log("Computer clicked");
    this.$router.push('/app');
  }
}

Alternatively, you can also bind the current Vue instance to the function like this:

let computerClick = (function (evt) {
  console.log("Computer clicked");
  this.$router.push('/app');
}).bind(this);
