First of all: the data dictionary routing in the project has been configured.

Dictionary problem of vue Project

We often encounter a dictionary problem in the project, which is a fixed array obtained from the background, and then used in many parts of the system through the select selection box. If you get it each time you use it, there are often two problems:

1. When the amount of data in this array is too large, it is possible to click on the select drop-down box. The data has not yet been returned, resulting in select being unable to select.

two。 Every time you re-request the backend, when the amount of data is too large and there are many other interfaces on the same page, the page loads slowly.

Write a dict.js file in utils

The contents are as follows:

/ / the key names in the encapsulated axiosimport {httpPost} from'@ / utils/axios'export function getDict (obj) {/ / this dictList are dictionary names That is, passing the corresponding name can get the corresponding list const dictList = {graduateSchool: [], major: [], topDegree: [], sex: [], title: [], workUnit: [], place: [], expertType: [],} for (let k in dictList) {httpPost ('/ sysdict/findByDictType') {dictType: `${k}`}) .then (res) = > {obj [k] = res.data})}} reference the getDict method just encapsulated in main.js

After import {getDict} from "@ / utils/dict.js" Vue.prototype.$dictObject = {} getDict (Vue.prototype.$dictObject), we can use it in the system.

"$dictObject. Dictionary name" instead of the corresponding list:
