Nuxt 3 directive and updating component data
I made a directive because I would like to be able to detect when a mouse click was outside a specific element. I will use this for a dropdown menu.
export default defineNuxtPlugin((nuxtApp) => {
nuxtApp.vueApp.directive('detect-click-outside', {
mounted (el) {
el.clickOutsideEvent = function (event) {
// // here I check that click was outside the el and his children
if (!(el == event.target || el.contains(event.target))) {
// and if it did, change data from directive
console.log("click is inside")
}
console.log("click is outside")
// update a value (name: clickedOutside) in the component
// where this directive is used
};
document.body.addEventListener('click', el.clickOutsideEvent)
},
})
})
The problem I am facing, and unable to find an answer for on the internet, is how I can update "data" from the component in which the directive is used.
For example:
const clickedOutside = false;
When I click outside, the directive should update the above line in the component used. For example the "mainMenu" component.
Does anyone know how I can do that?
Sample code of the menu:
<script setup>
const isDropdwonMenuVisible = ref(false);
</script>
<template>
<div class="mx-auto max-w-screen-2xl flex border-b border-gray:50 py-4 text-sm" v-detect-click-outside>
<div class="flex items-center text-lg font-bold cursor-pointer" v-for="(dataKey, dataIndex) in data" :keydata="dataIndex" @click="currentOpened = dataIndex">
{{ dataIndex }} <img src="images/icons/chevron-down-solid.svg" width="12px" class="ml-4" />
</div>
{{ currentOpened }}
</div>
