devServer proxy代理

• devServer proxy代理 注释笔记

module.exports = {
    // 默认情况下，Vue CLI 会假设你的应用是被部署在一个域名的根路径上
    // 例如 https://www.ruoyi.vip/。如果应用被部署在一个子路径上，你就需要用这个选项指定这个子路径。例如，如果你的应用被部署在 https://www.ruoyi.vip/admin/，则设置 baseUrl 为 /admin/。
	publicPath: process.env.NODE_ENV === 'production' ? '/switchboard/' : '/',
    
    // 在npm run build 或 yarn build 时 ，生成文件的目录名称（要和baseUrl的生产环境路径一致）（默认dist）
    outputDir: `switchboard-1.0.0`,
    
    // 用于放置生成的静态资源 (js、css、img、fonts) 的；（项目打包之后，静态资源会放在这个文件夹下）
    assetsDir: 'static',
    
    // 是否开启eslint保存检测，有效值：ture | false | 'error'
    lintOnSave: process.env.NODE_ENV === 'development',
    
    // 如果你不需要生产环境的 source map，可以将其设置为 false 以加速生产环境构建。
    productionSourceMap: false,
    
    // webpack-dev-server 相关配置
    devServer: {
        // https: true, // 开启https服务器
        host: 'localhost', // 目标服务器主机ip
        port: 8080, // 目标服务器主机端口号
        
        // proxy:{'/api':{}},代理器中设置/api,项目中请求路径为/api的替换为target
        proxy: {
            '/switchboard-web': {
                target: process.env.VUE_APP_ADDRESS,
                changeOrigin: true,

                }

ElementUI循环生成的Form表单项添加校验规则

• el-form-item 循环数据添加校验规则

template模板代码片段

<el-form
  :inline="true"
  :model="relDistributeForm"
  class="demo-form-inline"
  label-position="right"
  label-width="75px"
  ref="relDistributeFormRef"
>
  <template v-for="(item, index) in relDistributeForm.deptUserList">
	<!-- Form表单项添加校验规则 -->
    <el-form-item
      :label="item.name"
      :prop="`deptUserList.${index}.assignNum`"
      :rules="relDistributeFormRules.assignNum"
      :key="item.userCode"
    >
      <el-input v-model="item.assignNum" placeholder=""> </el-input>
    </el-form-item>
  </template>
</el-form>

:prop="deptUserList.${index}.assignNum"，deptUserList是v-for绑定的数组，index是索引，assignNum是表单绑定v-model的每一项名称

注意：template标签v-for绑定的数组绑定数组，key属性绑定在内部的子元素里面

data里面声明

export default {
	data() {
		  var checkTags = (rule, value, callback) => {
          	if (value.trim()) {
                if (isNaN(Number(value))) {
                	return callback(new Error('请输入数字值'))
                }
                if (!/^[0-9]+?$/.test(value)) {
                  	return callback(new Error('请输入非负整数'))
                }

                let assignNumList = this.relDistributeForm.deptUserList.map((item) => 
                  	return Number(item.assignNum)
                })
                let assignNumSum = assignNumList.reduce((prev, curr) => {
                  	return prev + curr
                })
                if (assignNumSum > this.multipleSelection.length) {
                  	return callback(new Error('分配超出范围'))
                }
                callback()
          	}
    	}
	}
}

ElementUI表单里面循环校验子组件项el-form-item

• el-form-item 循环数据添加校验规则

template模板代码片段

<el-form
  :model="editClientForm"
  :rules="editClientRules"
  ref="editClientRef"
  :disabled="editClientFormFlag"
>
	<el-row>
        <template v-for="(item, index) in editClientForm.customLebalList">
			<!-- 省略部分代码 -->
			<el-form-item
            	:label="item.fieldNameChina"
                :key="index"
                v-if="item.inputType == 4"
                label-width="100px"
                :required="item.mustFill == 1 ? true : false"          
            >
                <!-- 子组件 -->
                <AddressDetails
                      @input="handleChangeAdress"
                      :mustFill="item.mustFill"
                      :proList="`${JSON.stringify(item.proList)}`"
                      :cityList="`${JSON.stringify(item.cityList)}`"
                      :distList="`${JSON.stringify(item.distList)}`"
                      :fieldName="`${item.fieldName}`"
                      :addressValue="editClientForm[`${item.fieldName}`]"
                ></AddressDetails>
            </el-form-item>
		</template>
    </el-row>
</el-form>

引入子组件

import AddressDetails from '@/components/Address/addressDetails.vue'

data里面声明

export default {
	components: {
    	AddressDetails,
  	},
}

AddressDetails 子组件 === 省市区三级联动组件
