I am wondering how can we hide all shown elements on click outside from those elements in vue:

<button @click="div1=true">Show div 1</button>
<div v-if="div1">DIV 1</div>

<button @click="div2=true">Show div 2</button>
<div v-if="div2">DIV 2</div>

How can I hide all divs besides div 1 if I click on div 1 or hide all divs on click on some random part of the page? How does vuetify handle it?

• Just detect the click outside with a directive and iterate through the open divs and set their display/hide property to false. – Steven B. Commented Feb 25, 2019 at 20:36
• does not work for me even tho it works in fiddle I get Cannot set property 'event' of undefined – Learner Commented Feb 25, 2019 at 20:43
• Did you look at the specific answer I linked? not the selected answer of the question as that was for vue 1.x. – Steven B. Commented Feb 25, 2019 at 20:46

Vue way is to use this.$el (DOM element of current ponent), you can change this.$el and use any other HTMLElement

<div class="modal" @click="handleClick">
  <div class="modal-dialog">
    <div class="modal-content">
    ...
    </div>
</div>

And method should look like this

handleClick(e: Event): void {
  if (e.target instanceof HTMLElement && !this.$el.contains(e.target)) {
    this.$emit("hide"); //fires only on click outside
  }
}

• It's easy to detect click outside of the element if you know how event bubbling works in DOM.

• Hiding other divs works perfectly well when you put state of every div into the ponents's state.

Here is an example: https://codesandbox.io/s/0480m38mww?fontsize=14&module=%2Fsrc%2FApp.vue

I used this process so Home ponent would know that outside my Nav ponent has been clicked. It helps that I have my nav inside my Home Component.

My Home ponent template:

<div>
 <nav-bar ref="nav"></nav-bar>
  <div @click="useHideNavMethod()">

So I use ref="nav" to use methods from the Nav in my Home ponent. This means I can use the hideNav() method (which resides in Nav). I have purposely put the nav outside of this div with the click method, so anywhere clicked other than Nav would initiate the useHideNavMethod() function.

In my Nav ponent template I have:

<nav id="nav"> 

which is referenced when I use ref="nav".

So inside my hideNav() I have this.styleNavLi.display = 'none'; so it would hide the nav bar.

So all I need to do to use that method in Home is to use:

useHideNavMethod() {
 this.$refs.nav.hideNav();
}

Use div1 = !div1 for toggle view, Or use div1 = true for one time only.

<template>
  <div>
    {{ div1 }}
    <button @click="div1 = !div1">Show div 1</button>
    <div v-if="div1">DIV 1</div>

    {{ div2 }}
    <button @click="div2 = !div2">Show div 2</button>
    <div v-if="div2">DIV 2</div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      div1: true, // set default value as you want
      div2: false,
    };
  },
};
</script>
