在我的腦海，組件化是一切開發(fā)的基石，能夠復(fù)用的，絕不ctrl+v
vue雖然升級(jí)到3了，但是很多配套組件沒(méi)有更新，這里還是鞏固一下vue2吧，以后有時(shí)間再升級(jí)，這里使用的布局完全采用elementui，我并不擅長(zhǎng)樣式，寫那么多css感覺(jué)頭大，直接服用elementui，對(duì)后端工程師來(lái)講就像當(dāng)初寫bootstrap一樣，難度降低不少

1 定義組件
遇到Elements in iteration expect to have ‘v-bind:key’ directives.’ 這個(gè)錯(cuò)誤,
這里v-for key直接使用,因?yàn)槿≈翟揪褪俏ㄒ坏?br /> vue中計(jì)算屬性設(shè)計(jì)初衷是簡(jiǎn)單運(yùn)算，這里用來(lái)做動(dòng)態(tài)樣式倒是挺好
CSS 顏色

2 組件使用
通過(guò)自定義info屬性實(shí)現(xiàn)父子組件傳值，Vue 父子組件傳值 props
之前有些問(wèn)題，vue的雙向綁定,tableData是data中變量

<template><div><el-row><el-col :span="6" v-for="(bazi,index) in tableData" :key="index" class="text-center"><bazi-panel :info="bazi"></bazi-panel></el-col></el-row><el-row class="text-right"><el-pagination background layout="prev,pager,next" :total="total" :hide-on-single-page="true"@current-change="handleCurrentChange"></el-pagination></el-row></div> </template> <script> import BaziPanel from '@/components/BaziPanel' export default {name: "qr-table",components: {BaziPanel},data() {return {tableData:[],total:0,rows:10,page:1}},methods: {findQrList() {this.$store.dispatch("FindQrList", {page:this.page,rows:this.rows}).then(res => {if (res.success){this.tableData = res.data.rowsthis.total = res.data.totalconsole.log(this.baziList)}}).catch(err => {})},handleCurrentChange: function(currentPage){this.page = currentPagethis.findQrList()}},mounted: function(){this.findQrList()} } </script>

3 mockjs
yarn add mockjs --dev,添加以來(lái)后,上面的數(shù)據(jù)是寫死的，現(xiàn)在通過(guò)mockjs來(lái)模擬，
VUE項(xiàng)目中使用MOCK
下面的index.js將攔截所有的請(qǐng)求

const Mock = require('mockjs')// 設(shè)置攔截ajax請(qǐng)求的相應(yīng)時(shí)間 Mock.setup({timeout:'200-600'})let configArray = [];// 使用webpack的require.context()遍歷所有mock文件 const files = require.context('.', true, /\.js$/); files.keys().forEach((key) => {if (key === './index.js') return;configArray = configArray.concat(files(key).default); });// 注冊(cè)所有的mock服務(wù) configArray.forEach((item) => {for (let [path, target] of Object.entries(item)) {let protocol = path.split('|');Mock.mock(new RegExp('^' + protocol[1]), protocol[0], target);} });

這里使用到了mock生成數(shù)據(jù)的一些語(yǔ)法

import Mock from 'mockjs' import {getParams} from '@/utils/strUtil'let qrList = Mock.mock({'rows|100': [{//id:'@guid', // 四柱八字'yg|1':['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],'yz|1':['子','丑','寅','卯','辰','巳','午','未','申','酉','戌','亥'],'mg|1':['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],'mz|1':['子','丑','寅','卯','辰','巳','午','未','申','酉','戌','亥'],'dg|1':['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],'dz|1':['子','丑','寅','卯','辰','巳','午','未','申','酉','戌','亥'],'hg|1':['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],'hz|1':['子','丑','寅','卯','辰','巳','午','未','申','酉','戌','亥'],// 天干十神'ygss|1':['財(cái)','才','印','梟','官','殺','食','傷','比','劫'],'mgss|1':['財(cái)','才','印','梟','官','殺','食','傷','比','劫'],'hgss|1':['財(cái)','才','印','梟','官','殺','食','傷','比','劫'],// 十二長(zhǎng)生yzcs:'病',mzcs:'胎',dzcs:'衰',hzcs:'長(zhǎng)生',// 納音yny:'霹靂火',mny:'古柳木',dny:'海中金',hny:'楊柳木',// 地支藏干yzcg:"@shuffle(['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],1,3)",mzcg:"@shuffle(['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],1,3)",dzcg:"@shuffle(['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],1,3)",hzcg:"@shuffle(['甲','乙','丙','丁','戊','己','庚','辛','壬','癸'],1,3)",// 地支藏干十神yzcgss:"@shuffle(['財(cái)','才','印','梟','官','殺','食','傷','比','劫'],1,3)",mzcgss:"@shuffle(['財(cái)','才','印','梟','官','殺','食','傷','比','劫'],1,3)",dzcgss:"@shuffle(['財(cái)','才','印','梟','官','殺','食','傷','比','劫'],1,3)",hzcgss:"@shuffle(['財(cái)','才','印','梟','官','殺','食','傷','比','劫'],1,3)"}] })export default {'get|find/qiangruo': option => {// 制造數(shù)據(jù)let params = getParams(option.url)let tableData = qrList.rows.slice((params.page-1)*params.rows,params.page*params.rows)return {success: true,data: {total:100,rows:tableData}}} }

從url中獲取參數(shù)

import Qs from 'qs'export function getParams(url){// 從url中獲取參數(shù)let location = url.indexOf('?')var params = {}if (location!=-1){let params_str = url.substr(location+1)return Qs.parse(params_str);}return params }
