turn off event listener in vue

I am trying to figure out how to remove the event listener in this scenario. Since I am calling a method from within the event listener function, I need to use ES6 syntax and can't use named functions. How can I go about removing the event listener?

methods :
    initCanvas : function(x, y, width, height) {
        //perform initialization tasks for canvas
    },
    some_method : function() {
        let svgObjectEl = // logic to fetch the object element embedding the SVG
        const loadEventHandler = () => {
            // Retrieve values for x, y, width, height
            // Do some operations here
            this.initCanvas(x, y, width, height);         
        };
        
        svgObjectEl.addEventListener('load', loadEventHandler);
        
        //Need to remove the event listener but unsure how to do it
}

Answer №1

Perhaps this is a potential solution?

functions: {
  startDrawing (x, y, width, height) {
    //perform certain actions
  },
  another_function() {
    svgElement.options = { x: 12, y: 13, … }
    svgElement.addEventListener('load', this.eventListener)
  },
  eventListener(evt) {
    // additional code goes here
    this.startDrawing(evt.target.options)
    svgElement.removeEventListener('load', this.eventListener)    
  }
}
