vue中获取dom元素中内容的方法:
vue中是通过给标签加ref属性,然后在js中利用ref去引用它,从而操作该dom元素。
示例:
<template><div>
<div id="box" ref="mybox">
DEMO
</div>
</div>
</template>
<script>
export default {
data () {
return {
}
},
mounted () {
this.init();
},
methods:{
init() {
const self = this;
this.$refs.mybox.style.color = 'red';
setTimeout(() => {
self.$refs.mybox.style.color = 'blue';
},2000)
}
}
}
</script>
<style scoped>
#box {
width: 100px;
height: 100px;
line-height: 100px;
font-size: 20px;
text-align: center;
border: 1px solid black;
margin: 50px;
color: yellow;
}
</style>
