How to reference the framework in uni-app

本教程操作环境:windows7系统、uni-app2.5.1版,DELL G3电脑。

uni-app怎么引用框架?

在uni-app中引入uview-ui框架

方法1:通过hbuilder直接创建的uni-app项目

1、安装  

1)uview-ui

   插件下载地址:https://ext.dcloud.net.cn/plugin?id=1593

   此下载的是一个新项目,可单独将其中的uview-ui文件夹复制出来放在你的项目的根目录下

2)SCSS

   uView依赖SCSS,您必须要安装此插件,否则无法正常运行。

   安装方法:HX菜单的 工具->插件安装中找到"scss/sass编译"插件进行安装, 如不生效,重启HX即可

   

3)package.json

// 如果您的项目是HX创建的,根目录又没有package.json文件的话,请先执行如下命令:
// npm init -y
Copy after login
Copy after login

2、配置

1)引入uView主JS库

在项目根目录中的main.js中,引入并使用uView的JS库,注意这两行要放在import Vue之后。

// main.js
import uView from "uview-ui";
Vue.use(uView);
Copy after login
Copy after login

2)在引入uView的全局SCSS主题文件

在项目根目录的uni.scss中引入此文件。

/* uni.scss */
@import 'uview-ui/theme.scss';
Copy after login
Copy after login

3)引入uView基础样式

注意!

在App.vue中style部分首行的位置引入,注意给style标签加入lang="scss"属性

温馨提示

由于uView的内置样式均是写在scss文件中的,您在使用的时候,请确保要给页面的style标签加上lang="scss"属性,否则可能会报错。

<style>
    /* 注意要写在第一行,同时给style标签加入lang="scss"属性 */
    @import "uview-ui/index.scss";
</style>
Copy after login
Copy after login

4)配置easycom组件模式

此配置需要在项目根目录的pages.json中进行。

温馨提示

uni-app为了调试性能的原因,修改easycom规则不会实时生效,配置完后,您需要重启HX或者重新编译项目才能正常使用uView的功能。

请确保您的pages.json中只有一个easycom字段,否则请自行合并多个引入规则。

// pages.json
{
    "easycom": {
        "^u-(.*)": "@/uview-ui/components/u-$1/u-$1.vue"
    },
    
    // 此为本身已有的内容
    "pages": [
        // ......
    ]
}
Copy after login
Copy after login

3、页面使用

通过npm和下载方式的配置之后,在某个页面可以直接使用组件,无需通过import引入组件。

<template>
    <u-action-sheet :list="list" v-model="show"></u-action-sheet>
</template>
<script>
    export default {
        data() {
            return {
                list: [{
                    text: &#39;点赞&#39;,
                    color: &#39;blue&#39;,
                    fontSize: 28
                }, {
                    text: &#39;分享&#39;
                }, {
                    text: &#39;评论&#39;
                }],
                show: true
            }
        }
    }
</script>
Copy after login
Copy after login

方法2:项目是由vue-cli模式创建的

1、安装

1)uview-ui

方法1 直接下载文件包:

插件下载地址:https://ext.dcloud.net.cn/plugin?id=1593

此下载的是一个新项目,可单独将其中的uview-ui文件夹复制出来放到项目的src文件夹中即可。

方法2 npm安装

npm install uview-ui
Copy after login

2)scss

// 安装node-sass
npm i node-sass -D
// 安装sass-loader
npm i sass-loader -D
Copy after login

3)package.json

// 如果您的项目是HX创建的,根目录又没有package.json文件的话,请先执行如下命令:
// npm init -y
Copy after login
Copy after login

2、配置

1)引入uView主JS库

在项目根目录中的main.js中,引入并使用uView的JS库,注意这两行要放在import Vue之后。

// main.js
import uView from "uview-ui";
Vue.use(uView);
Copy after login
Copy after login

2)在引入uView的全局SCSS主题文件

在项目根目录的uni.scss中引入此文件。

/* uni.scss */
@import &#39;uview-ui/theme.scss&#39;;
Copy after login
Copy after login

3)引入uView基础样式

注意!

在App.vue中style部分首行的位置引入,注意给style标签加入lang="scss"属性

<style>
    /* 注意要写在第一行,同时给style标签加入lang="scss"属性 */
    @import "uview-ui/index.scss";
</style>
Copy after login
Copy after login

4)配置easycom组件模式

此配置需要在项目根目录的pages.json中进行。

温馨提示

uni-app为了调试性能的原因,修改easycom规则不会实时生效,配置完后,您需要重启HX或者重新编译项目才能正常使用uView的功能。

请确保您的pages.json中只有一个easycom字段,否则请自行合并多个引入规则。

// pages.json
{
    "easycom": {
        "^u-(.*)": "@/uview-ui/components/u-$1/u-$1.vue"
    },
    
    // 此为本身已有的内容
    "pages": [
        // ......
    ]
}
Copy after login
Copy after login

3、页面使用

通过npm和下载方式的配置之后,在某个页面可以直接使用组件,无需通过import引入组件。

<template>
    <u-action-sheet :list="list" v-model="show"></u-action-sheet>
</template>
<script>
    export default {
        data() {
            return {
                list: [{
                    text: &#39;点赞&#39;,
                    color: &#39;blue&#39;,
                    fontSize: 28
                }, {
                    text: &#39;分享&#39;
                }, {
                    text: &#39;评论&#39;
                }],
                show: true
            }
        }
    }
</script>
Copy after login
Copy after login
