In the following example I made a simple image spinner loader with Vue.js:

The problem is that, especially with larger images, the image often loads piece by piece. That doesn't look good to the user.
The picture should only be displayed when it is fully loaded. As long as the image is not fully loaded, the spinner should be displayed.
What can I do to make it work?

The image will be emitting an event load which will be fired once the image is loaded.
new Vue({ el: "#app", data: { imgsrc: "", btntext: "Show Image", isLoaded: false, isLoading: false }, methods: { loaded() { this.isLoaded = true; this.isLoading = false; }, toggleimg: function(){ if (this.imgsrc == "") { this.isLoaded = false; this.isLoading = true; this.imgsrc = "" this.btntext = "Hide Image" }else{ this.imgsrc = "" this.btntext = "Show Image" } } } }).loading { background: transparent url(') center no-repeat; height: 400px; width: 400px; }<script src=""></script> <div> <h2>Image Loader Spinner</h2> <button @click="toggleimg">{{ btntext }}</button> <div v-if="isLoading"></div> <img v-show="isLoaded" :src="imgsrc" width="400" @load="loaded"> </div>Using new Image()
var myImage = new Image(); myImage.src = ' myImage.onload = () => { this.imgsrc = myImage.src } this.imgsrc = ' this.btntext = "Hide Image"
