[Solved] Uncaught (in promise) NavigationDuplicated: Avoided redundant navigation to current location

Problem description

When using Vue router code for route jump, click a link repeatedly and report the following error


Avoid repeated navigation to this address. In short, don’t click repeatedly in the same place.


Add the following code in index.JS under the router folder:

Note: before creating a routing instance

import VueRouter from "vue-router"

const originalReplace = VueRouter.prototype.replace
VueRouter.prototype.replace = function (location) {
  return originalReplace.call(this, location).catch(err => err)

It seems that the other party declares a variable to point to the original replace function, and then re declares the new replace function. When we call the replace function of router again, we execute the new replace function, and then catch exceptions to enable the program to continue to execute later
