Connect the B-Button to an input file using BootstrapVue

I am attempting to create an input file button within a v-for loop without using the b-form-file tag. Despite trying various solutions, none of them have worked for me.

Here is the code I have so far:

<b-button @click="selectFile()" variant="success" :id="index"> Upload </b-button>
<input type="file" ref="file" style="display: none;"/>

And this is my script/methods section:

methods: {
  selectFile() {
    this.$refs.file
  }
}

Currently, when I click the button nothing happens and no errors are displayed. Any assistance would be greatly appreciated!

Answer №1

Rather than opting for a traditional button, consider using a <label> element in conjunction with the for attribute. By utilizing CSS, you can customize the label to resemble a button.

<label for="file" class="btn btn-success"> Upload </label>
<input id="file" type="file" style="display: none;" />

If you are incorporating this within a v-for loop, you will need to create dynamic IDs for your inputs. One approach is to use a unique identifier associated with your items, or alternatively utilize the index.

<div v-for="(item, index) in items">
  <label :for="`file-${index}`" class="btn btn-success"> Upload </label>
  <input :id="`file-${index}`" type="file" style="display: none;"/>
</div>

In Vue using BootstrapVue:

Explanation of how the following code operates:

  1. Click on a button to open the file explorer;
  2. Select a file and proceed;
  3. The @onChange event will detect the new file being selected;
<label>
  <button/> //this could be an icon, link,...
  <input @change="doSomething" type="file" ref="file" accept="image/gif, 
    image/jpeg, image/png" hidden/>
</label>
  1. Manage the selected file
doSomething(e: any) { 
  const file = e.target.files[0]
}
