If you do operations such as adding/modifying/deleting etc. in a project, you usually need to refresh the data or refresh the current page.

Thinking

(1) If the page is simple, just call the interface to refresh the data.
(2) If the page is complex, you need to call Multiple interfaces or notifying multiple sub-components to refresh can be done by refreshing the current page. Here are 3 ways to refresh the current page. Each method has different ideas and has its own advantages and disadvantages

Method 1 - Via location.reload and $router.go(0) methods

(a) Overview

Pass# Both ##location.reload and $router.go(0) can achieve page refresh. It uses the browser refresh function, which is equivalent to pressing the f5 key to refresh the page.

Advantages: Simple enough
##Disadvantages
: There will be blank pages and poor user experience good. [Related recommendations: vuejs video tutorial, web front-end development]

Method 3-Through provide and inject

##(a) Overview

By 975b587bf85a482ea10b0a28848e78a4dd6e4ababe59793a4ac75fb9e5c5550e## on the parent page #Add v-if control

to refresh the page by destroying and recreating the page, and use

provide and inject to implement multi-level component communication. The parent page provides the reload method through provide, and the child page obtains the reload method through inject, and calls the method to refresh Advantages

: There will be no blank pages, there will be no quick switching process in the address bar, and the user experience is good

Disadvantages
: The implementation is slightly complicated, involving
and
inject communication between multi-level components, and v-if control component creation and destruction, and$nextTickApplication of event loop(b)Code
