Enhancing appearance with $refs?

Having trouble adding style to the $refs attribute. I keep getting an error message saying "Cannot set property 'cssText' of undefined." Is there a way to accomplish this task? I haven't come across anything similar to this issue before.

this.$refs['ticketCode_'+this.resoTrans_id].style.cssText =
                "background-color:#66BB6A !important; border:1px solid #66BB6A !important; color:#fff !important;";

Interestingly, when printing out without using .style, everything seems to work fine:

console.log(this.$refs['ticketCode_'+this.resoTrans_id])

VueComponent {_uid: 493, _isVue: true, $options:

Answer №1

A recommended approach is to avoid using cssText and instead utilize the JavaScript API for setting styles (which can also be done on $refs):

let $ref = this.$refs['ticketCode_' + this.resoTrans_id]

$ref.style.backgroundColor = '#66bb6a';
$ref.style.border = '1px solid #66bb6a';
...

An even more efficient way is to leverage Vue's capabilities directly in your template:

<your-element ref="'ticketCode_' + resoTrans_id" :style="{ backgroundColor: '#66bb6a', border: '1px solid #66bb6a' /* ... */ }" />

Answer №2

In order to adjust the styling of the $ref's element property, you will need to directly target the $el property. It is important to note that your $ref represents a Vue Component (as indicated by the console output of your $ref), and not just an HTML element:

this.$refs['ref-name'].$el.style.top = `${topVal}px`

Answer №3

use the object key in $refs to apply styling directly

this.$refs['ticketCode_' + this.resoTrans_id].style.background="red"
