在uniapp小程序中,如何让当前数据全局使用 ,请使用vue3写法 const { sys_user_sex, house_resource_name, supporting_facilities, house_type, house_floor, house_model, house_toward, pay_method, select_rent, select_area, select_sort, } = proxy.useDict( "house_resource_name", "supporting_facilities", "house_type", "house_floor", "house_model", "house_toward", "pay_method", "sys_user_sex", "select_rent", "select_area", "select_sort" );

在Vue3中,可以通过使用provide和inject来实现全局数据的使用。具体步骤如下:
1. 在App.vue文件中,使用provide将需要全局使用的数据传递给子组件,例如:
```
<template>
<div>
<router-view :dictData="dictData" />
</div>
</template>
<script>
import { provide } from 'vue';
import proxy from '@/utils/proxy';
export default {
setup() {
const {
sys_user_sex,
house_resource_name,
supporting_facilities,
house_type,
house_floor,
house_model,
house_toward,
pay_method,
select_rent,
select_area,
select_sort,
} = proxy.useDict(
"house_resource_name",
"supporting_facilities",
"house_type",
"house_floor",
"house_model",
"house_toward",
"pay_method",
"sys_user_sex",
"select_rent",
"select_area",
"select_sort"
);
// 使用provide将数据传递给子组件
provide('dictData', {
sys_user_sex,
house_resource_name,
supporting_facilities,
house_type,
house_floor,
house_model,
house_toward,
pay_method,
select_rent,
select_area,
select_sort,
});
return {
dictData: {
sys_user_sex,
house_resource_name,
supporting_facilities,
house_type,
house_floor,
house_model,
house_toward,
pay_method,
select_rent,
select_area,
select_sort,
},
};
},
};
</script>
```
2. 在需要使用这些数据的组件中,使用inject获取全局数据,例如:
```
<template>
<div>
<!-- 使用inject获取全局数据 -->
<p>{{ dictData.sys_user_sex }}</p>
</div>
</template>
<script>
import { inject } from 'vue';
export default {
props: {
dictData: {
type: Object,
default: () => ({}),
},
},
setup() {
// 使用inject获取全局数据
const dictData = inject('dictData');
return {
dictData,
};
},
};
</script>
```
这样,就可以在整个应用中使用这些全局数据了。注意,由于使用了Vue3新的语法,需要在项目中安装Vue3的相关包。
