Agregue CSS a Vue usando JavaScript

Estoy tratando de agregar estilo a esta <label> en Vue .

 <div class="grid grid-cols-1 mt-5 mx-7"> <label class="uppercase md:text-sm text-xs text-gray-500 text-light font-semibold mb-1 flex items-center justify-center">Upload Photo</label> <div class='flex items-center justify-center w-full'> <label id="img1" class='flex flex-col border-4 border-dashed w-40 h-32 hover:bg-gray-100 hover:border-purple-300 group'> <div @click="onPrimaryPicSelected" class='flex flex-col items-center justify-center pt-7'> <svg class="w-10 h-10 text-purple-400 group-hover:text-purple-600" fill="none" stroke="currentColor" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"><path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M4 16l4.586-4.586a2 2 0 012.828 0L16 16m-2-2l1.586-1.586a2 2 0 012.828 0L20 14m-6-6h.01M6 20h12a2 2 0 002-2V6a2 2 0 00-2-2H6a2 2 0 00-2 2v12a2 2 0 002 2z"></path></svg> <p class='lowercase text-sm text-gray-400 group-hover:text-purple-600 pt-1 tracking-wider'>Select a photo</p> </div> <input type='file' class="hidden" /> </label> </div> </div>

Quiero que cuando se llame a la función onPrimaryPicSelected agregue un estilo CSS a la <label> . ¿Cómo puedo hacer esto si es posible?

Actualmente, onPrimaryPIcSelected solo obtiene la imagen que se cargó.

 onPrimaryPicSelected(event) { this.primaryPhoto = event.target.files[0]; this.primaryPhotoUrl = URL.createObjectURL(event.target.files[0]); },

Puede usar una variable booleana si es verdadera, aplicará su estilo a la etiqueta de la etiqueta.

 <div class="grid grid-cols-1 mt-5 mx-7"> <label class="uppercase md:text-sm text-xs text-gray-500 text-light font-semibold mb-1 flex items-center justify-center" :style="selected ? 'your-style-here' : ''">Upload Photo</label> <div class='flex items-center justify-center w-full'> <label id="img1" class='flex flex-col border-4 border-dashed w-40 h-32 hover:bg-gray-100 hover:border-purple-300 group'> <div @click="onPrimaryPicSelected" class='flex flex-col items-center justify-center pt-7'> <svg class="w-10 h-10 text-purple-400 group-hover:text-purple-600" fill="none" stroke="currentColor" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"><path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M4 16l4.586-4.586a2 2 0 012.828 0L16 16m-2-2l1.586-1.586a2 2 0 012.828 0L20 14m-6-6h.01M6 20h12a2 2 0 002-2V6a2 2 0 00-2-2H6a2 2 0 00-2 2v12a2 2 0 002 2z"></path></svg> <p class='lowercase text-sm text-gray-400 group-hover:text-purple-600 pt-1 tracking-wider'>Select a photo</p> </div> <input type='file' class="hidden" /> </label> </div> </div>

entonces en tu funcion

 onPrimaryPicSelected(event) { this.selected = true; this.primaryPhoto = event.target.files[0]; this.primaryPhotoUrl = URL.createObjectURL(event.target.files[0]); },
