当点击 div 内部的按钮时，防止点击父级

当单击 div 中的按钮时，是否可以阻止 <div>元素上的函数运行？

当单击按钮元素时，函数: toggleSystemDetails不应该被触发? 在 Vue 中这可能吗？

<div v-on:click="toggleSystemDetails($event, system.id)" v-for="(system, index) in organization.systems" :key="system.id">
Outer Div
<button v-on:click="toggleTileOptionsMode($event, system.id, system.name, system.layout)">
Inner Button
</button>
</div>

Have a look at Event Modifiers in the Vue.js v3 docs (v2 docs here), v-on:click.stop will stop that click from propagating or "bubbling" up to the parent element.

as mentioned on the link provided by Justin you can .self in the click event

<!-- only trigger handler if event.target is the element itself -->
<!-- i.e. not from a child element -->
<div v-on:click.self="doThat">...</div>

Here is how to master this problem.

Say you have a parent element and some child elements.

1.(1st case) You want the parent click to do not affect the child clicks. Just put at the parent element the .self modifier:

  <div class="parent" @click.self="parent"> <!-- .self modifier -->
<span class="child" @click="child1">Child1</span>
<span class="child" @click="child2">Child2</span>
<span class="child" @click="child3">Child3</span>
</div>

See it in action here

note: if you remove the .self when you click a child, the parent event will fire too.

2.(2nd case) You have the below code:

  <div @click="parent">
Click to activate
<i class="fa fa-trash" title="delete this" @click="delete_clicked"></i>
</div>

The problem is:

  1. When you click the icon element the parent click will fire. (you don't want this)
  2. You can NOT use the 1st solution because you want to fire the parent event even if the text "Click to activate" gets clicked.

The solution to this is to put the .stop modifier to the icon element so the parent event will not fire.

I just want to put my two cents here, since I do find myself looking for this problem again and again (one day I will remember).

I have found in some instances, the child element needs @click.stop.prevent and that's it, to stop it from bubbling to the parent. I assume v-on:click.stop.prevent would have the same effect (non-shorthand).

additionally, if a child element detains you from clicking the parent element, you can fix this by adding CSS to the child element pointer-events: none. this solution is valid if there is no event in the child element.

You can use @click.stop on child component, for examaple

.modal(@click="myfunc")
default-content(@click.stop)
