In some cases, the vue reactivity system doesn’t enough to detect the dom changes, so that we need to force update the vue components to re-render.
The forceUpdate method
Vue offers us a built-in method called forceUpdate(), by using this method inside vue instance we can force update the component.
Let’s see an example:
<template> <div id="app"> <h1>{{Math.random()}}</h1> <button @click="update">Force Update</button> </div></template><script>export default { methods:{ update(){ this.$forceUpdate(); } }};</script>In the above example, we have attached an update method to the button element.
Inside the update method we have added a this.$forceUpdate() method, so that when we click on a button, it will re-render the component with a new random number.
Using the mount method
The mount method is used to manually connect the vue instance to the dom, which will trigger the component to re-render.
Here is an example:
<template> <div id="app"> <h1>{{Math.random()}}</h1> <button @click="update">Force Update</button> </div></template><script>export default { methods:{ update(){ this.$mount(); } }};</script>Hope this code and post will helped you for implement How to force update the Vue component to re-render. if you need any help or any feedback give it in comment section or you have good idea about this post you can give it comment section.
