If you have a component with multiple elements inside of the root element you can use this It just works™ solution with a boolean.

<template>
  <div @click="clickInside"></div>
<template>

<script>
export default {
  name: "MyComponent",
  methods: {
    clickInside() {
      this.inside = true;
      setTimeout(() => (this.inside = false), 0);
    },
    clickOutside() {
      if (this.inside) return;
      // handle outside state from here
    }
  },
  created() {
    this.__handlerRef__ = this.clickOutside.bind(this);
    document.body.addEventListener("click", this.__handlerRef__);
  },
  destroyed() {
    document.body.removeEventListener("click", this.__handlerRef__);
  },
};
</script>

I create a div at the end of the body like that:

<div v-if="isPopup" class="outside" v-on:click="away()"></div>

Where .outside is :

.outside {
  width: 100vw;
  height: 100vh;
  position: fixed;
  top: 0px;
  left: 0px;
}

And away() is a method in Vue instance :

away() {
 this.isPopup = false;
}

Easy, works well.

There are already many answers to this question, and most of them are based on the similar custom directive idea. The problem with this approach is that one have to pass a method function to the directive, and cannot directly write code as in other events.

I created a new package vue-on-clickout that is different. Check it out at:

• https://github.com/MuTsunTsai/vue-on-clickout

It allows one to write v-on:clickout just like any other events. For example, you can write

<div v-on:clickout="myField=value" v-on:click="myField=otherValue">...</div>

and it works.

You can register two event listeners for click event like this

document.getElementById("some-area")
        .addEventListener("click", function(e){
        alert("You clicked on the area!");
        e.stopPropagation();// this will stop propagation of this event to upper level
     }
);

document.body.addEventListener("click", 
   function(e) {
           alert("You clicked outside the area!");
         }
);
