How does vuejs get elements?

Get dom elements in Vue

Although Vue.js is said to be data-driven, sometimes we have to get dom objects to do some operations.

Different versions of vue have different ways to get dom objects

In Vue.js version 1. 0, it is bound through v-el and then obtained through this.els.XXX.

In version 2.0 of Vue.js. We get it by binding ref= "XXX" to the element and then through this.$refs.XXX or this.refs ['XXX']

Take 2.0 as an example:

Hello World ~ Click export default {methods: {get () {console.log (this.$refs ['hello']); console.log (this.$refs.hello);}

You need to be careful with dom in vue, especially when adding or removing dom, especially mounted () and created (), when the dom object has not yet been generated and should be placed in the callback function of this.nextTick ().
