Can you help me retrieve the value wwww from the ref attribute?
<form @submit.prevent enctype="multipart/form-data">
<input type="file" ref="wwww" @change="selectFile">
</form>
I have tried the following method:
console.log(this.$refs.wwww)
However, instead of getting the desired value, I am receiving the following output:
<input type="file">
Could you please assist me in retrieving it like this: wwww
Referring to DOM elements using refs is a key feature. If you need to store custom data on an element for JavaScript access, consider utilizing data attributes:
<input type="file" ref="inputElement" data-whatever="wwww">
To retrieve the data:
const { inputElement } = this.$refs;
console.log(inputElement.dataset.whatever); // "wwww"
