Tips on accessing a file in v-file-input

<v-file-input
    accept="image/*"
    label="File input"
    v-model="chosenFile"
></v-file-input>

I'm working with Vue.js. How can I access the content of the files?

var reader = new FileReader();
var img = new Image();
reader.readAsDataURL(this.chosenFile)

When using FileReader, nothing is displayed.

Answer №1

Check out this code snippet on CodePen: https://codepen.io/eveningforgery/pen/KKzWrwq

To display or save the image, you must utilize the reader's result which contains the binary large object (blob) of the image.

<img v-if="data" :src="data" alt="">
importImage() {
  var reader = new FileReader();
      
  // Utilize the JavaScript reader object to fetch the content
  // of the file assigned in the v-model attribute
  reader.readAsDataURL(this.chosenFile)
  reader.onload = () => {
    this.data = reader.result;
  }
}
