Copy url to clipboard via button click in a vuejs component

Question

I have following component, and I would like to have a button that copies the link_url to the clipboard on click.

I have javascript code that works when selecting an id, however the links do not have an id. Can I accomplish the selection of the a-tag via refs in the component itself, or what would be the best way to get this done.

I was also thinking about generating an a-tag with the this.link_url in the copyURL() dynamically but I guess that would be very dirty.. I am looking for the vuejs way.

<template>
  <li class="list-group-item">
    <a :href="link_url" 
         class="text-dark" 
         target="_blank" 
         rel="noopener noreferrer">{{ link_name }}</a>
    <button @click="copyUrl">copy url from a tag</button>
  </li>      
</template>

<script>
export default {
  props: ["link_url", "link_name"],
  methods: {
    copyURL() {
      var Url = document.getElementById('myid'); /*GET vuejs el reference here (via $ref) but how?*/
      Url.innerHTML = window.location.href;
      console.log(Url.innerHTML)
      Url.select();
      document.execCommand("copy");
    }
  }
}
</script>

<style>
</style>

Answer 1

If you need to use vuejs ref add it as attribute

<a :href="link_url" class="text-dark" target="_blank" rel="noopener noreferrer" ref="mylink">
    {{ link_name }}
</a>

and use it in your method in the following way:

  methods: {
    copyURL() {
      var Url = this.$refs.mylink;
      Url.innerHTML = window.location.href;
      console.log(Url.innerHTML)
      Url.select();
      document.execCommand("copy");
    }
  }

However, you should take a look to this link for a better cross-browsing solution. In this case you don't need the ref attribute.

This is the solution in the link adapted to your case:

methods: {
    copyUrl() {
        const el = document.createElement('textarea');  
        el.value = this.link_url;                                 
        el.setAttribute('readonly', '');                
        el.style.position = 'absolute';                     
        el.style.left = '-9999px';                      
        document.body.appendChild(el);                  
        const selected =  document.getSelection().rangeCount > 0  ? document.getSelection().getRangeAt(0) : false;                                    
        el.select();                                    
        document.execCommand('copy');                   
        document.body.removeChild(el);                  
        if (selected) {                                 
          document.getSelection().removeAllRanges();    
          document.getSelection().addRange(selected);   
        }
    }
}

You can use navigator object with clipboard in javascript.

Note: navigator.clipboard.writeText is asynchronous.

methods: {
  async copyURL(mytext) {
    try {
      await navigator.clipboard.writeText(mytext);
      alert('Copied');
    } catch($e) {
      alert('Cannot copy');
    }
  }
}

Answer 3

Most modern web explorers (2021) let you use this: navigator.clipboard.writeText("yourText");

Just in case you can also do this:

  const clipboardData =
    event.clipboardData ||
    window.clipboardData ||
    event.originalEvent?.clipboardData ||
    navigator.clipboard;

  clipboardData.writeText(message);

Answer 4

does not work for me, try this -

<input type="hidden" id="testing-code" :value="testingCode">

copyTestingCode () {
      let testingCodeToCopy = document.querySelector('#testing-code')
      testingCodeToCopy.setAttribute('type', 'text') 
      testingCodeToCopy.select()

      try {
        var successful = document.execCommand('copy');
        var msg = successful ? 'successful' : 'unsuccessful';
        alert('Testing code was copied ' + msg);
      } catch (err) {
        alert('Oops, unable to copy');
      }

      /* unselect the range */
      testingCodeToCopy.setAttribute('type', 'hidden')
      window.getSelection().removeAllRanges()
    },

TRY THIS FUNCTION:

async copy(mytext) {
               var input = document.createElement('input');
               input.setAttribute('value', mytext);
               input.value = mytext;        
               document.body.appendChild(input);
               try {
                    input.select();    
                    input.click();     
                    input.focus();
                    var successful = document.execCommand('copy');
                    var msg = successful ? 'successful' : 'unsuccessful';
                    console.log('Testing code was copied ' + successful + ' ' + msg);
                    
               } catch (err) {
                    console.log('Oops, unable to copy');
               }
               document.body.removeChild(input);          
          }
