Copy password input field content in Vue to clipboard

Question

Copy password input field content in Vue to clipboard

I'm currently working on a Vue app that includes a form input for creating passwords. I've managed to implement a button that shows/hides the password, but I'm struggling with adding a copy to clipboard function. It doesn't seem to be working as expected. Can you help me identify what I'm doing wrong?

Code snippet

<small class="font-wieght-bold text-success mb-0" v-if="isCopied">Copied</small>
      
<div class="input-group">
  <input :type="showPassword ? 'text' : 'password'" class="form-control" ref="password" required v-model="password">
  <div class="input-group-append">
    <button class="btn btn-secondary" @click.prevent="copyToClipboard()"><i class="fas fa-clipboard"></i></button>
  </div>
</div>

Vuex code part

viewPassword() {
  this.showPassword = !this.showPassword;
},
copyToClipboard() {
  this.$refs.password.select();
  document.execCommand('copy');
  this.isCopied = true;
  setTimeout( () => { this.isCopied = !this.isCopied },3000);
}

To effectively copy the contents of your v-model, focus on extracting the data rather than duplicating the input itself.

A useful approach is to implement a function that facilitates copying from a variable.

This function creates a new text box, utilizes the copy command, and promptly removes it within a single event loop to prevent rendering.

const copyTextToClipboard = (text) => {
  const textArea = document.createElement('textarea')

  // Styling added for necessary functionality and minimal visual impact

  textArea.style.position = 'fixed'
  textArea.style.top = '0'
  textArea.style.left = '0'

  textArea.style.width = '2em'
  textArea.style.height = '2em'

  textArea.style.padding = 0

  textArea.style.border = 'none'
  textArea.style.outline = 'none'
  textArea.style.boxShadow = 'none'

  textArea.style.background = 'transparent'

  textArea.value = text

  document.body.appendChild(textArea)

  textArea.select()

  try {
    const successful = document.execCommand('copy')
    const msg = successful ? 'successful' : 'unsuccessful'
    console.log('Copying text command was ' + msg)
  } catch (err) {
    console.log('Oops, unable to copy')
  }

  document.body.removeChild(textArea)
}

After exploring different options, I discovered a new approach using the clipboard API as an alternative solution to the accepted answer. By utilizing the clipboard.writeText() method, I was able to efficiently copy the v-modeled data directly into the clipboard, even when dealing with

<input type="password">

. Below is the improved version of the copyToClipboard() method:

    copyToClipboard() {
      navigator.clipboard.writeText(this.password);
      this.isCopied = true;
      setTimeout( () => { this.isCopied = !this.isCopied },3000);
    }
