Vue JS（提供、注入）
我们使用 provide 和 inject 将数据从父元素直接传输到任何子元素，在这段代码中我将向您展示如何使用它们
<template>
<h1>parent component</h1>
<div class="wrapper">
<h1>{{ user }}</h1>
<input type="text" placeholder="enter username" v-model="user.name">
<componentd :user="user"/>
</div>
</template>
import {reactive,provide} from "vue";
const user=reactive({
name:"jahongir",
age:30,
})
provide("user", user)
<template>
<div>
<div class="child-element">
<h1>d component</h1>
<h2>{{ user }}</h2>
</div>
</div>
</template>
<script setup>
import {inject} from "vue";
const user=inject("user");
结果是
总的来说，我们所做的是
- import {provide} from "vue"; provide imported by vue
- import {reactive} from "vue"; reactive imported by vue
- const user=reactive({name:"jahongir",age:30,}) reactive object created
- provide("user", user); in this case, first user in the string is optional name and the second value is our object that we should not be changed
在子元素中，我们接受如下所示的 inject 值
- import {inject} from "vue"; inject imported by vue;
- const user=inject("user"); user value from parent component token by veriable with any optional name.
- for example in the above we would write any names after const but we should give inside of inject provide's first string name "user"
- <h2>{{ user }}</h2> Finally we run it so on
