Tips for executing specific javascript on small screens or mobile devices

I am currently in the process of developing a Vue web application that needs to be functional on all devices. I have certain code that should only run on small screens or mobile devices. Right now, I am using an if statement with $(window).width() to achieve this, like so:

if ($(window).width() <= 768) {
  //My mobile specific code
}

Is there a more efficient or vue-specific way to handle this?

Edit

For instance, in one component, my code looks like this:

export default {
  data () {
    return {
      fade: false,
      showFilter: $(window).width() > 768
    }
  },
  components: { PrFilter, Pr },
  created () {
    if ($(window).width() <= 768) {
      bus.$on('pr-changed', () => {
        this.showFilter = false
        this.fade = false
      })
    }
  }
}

And in another component, I have the following:

watch: {
  matchingPr: function (filteredPr) {
    if (filteredPr.length) {
      this.pr = filteredPr[0]
      if ($(window).width() <= 768) {
        bus.$emit('pr-changed')
      }
    }
  }
},

Answer №1

to determine if the user is on a mobile device, you can employ this handy function:

function checkMobile() { 
 if( navigator.userAgent.match(/Android/i)
 || navigator.userAgent.match(/webOS/i)
 || navigator.userAgent.match(/iPhone/i)
 || navigator.userAgent.match(/iPad/i)
 || navigator.userAgent.match(/iPod/i)
 || navigator.userAgent.match(/BlackBerry/i)
 || navigator.userAgent.match(/Windows Phone/i)
 ){
    return true;
  }
 else {
    return false;
  }
}

This method utilizes the navigator.userAgent property.

Answer №2

If you're looking to accomplish this task, I recommend utilizing the vue-mediaquery plugin.

Personally, this solution was effective for my needs.

Feel free to give it a try and see if it works well for you too!

Answer №3

To ensure optimal performance, you can verify the condition and load JavaScript only when necessary.

<script>
if (window && window.innerWidth > 768) {
  document.write('<script type="text/javascript" src="bar.js"><\/script>');
}
</script>
