Preventing navigation to non-existent routes in Vue by disabling the forward and backward buttons

Hello, I have developed an app that functions as a plugin within another application, requiring me to manually handle forward and backward navigation. My Question: How can I disable the forward and backward buttons using the .disabled class when there are no more routes available? I am currently utilizing history mode for moving forward with go(1) and going back with go(-1). Follow these steps to understand my points:

Click on the Browse ++ button three times
Click on the < button three times until it becomes disabled
Click on the > button three times until it becomes disabled

See my code here: https://codesandbox.io/s/path-traversing-w6yy3f

javascript vue.js routes vue-router

Answer №1

I need to prevent the forward and backward buttons from being clicked by adding a .disabled class when there are no more routes available.

You can't disable a div element, since you have div elements for both the backward and forward buttons.

Therefore, I am currently removing the backward and forward divs from the document object model (DOM) based on a condition using v-if.

Here's a functioning method:

Regrettably, there is no direct way to track the current position in the browser history, so it needs to be monitored elsewhere.

This specific solution is effective when navigating through links, but not when using standard browser navigation.

UPDATE

The console errors on opensandbox have been resolved. The issue was related to:

 created() {
    console.log("thiss", this.$route);
  },

Removing the console.log command eliminates the error logs.

One convenient method to achieve this is by keeping track of a variable that points to the current index and adjusting it as you move forward or backward.

goBackward() {
  currentIndex--;
  this.$router.go(-1);
},

goForward() {
  currentIndex++;
  this.$router.go(1);
},
explore() {
  const param = this.generateRandomObject();
  this.$router.push({ name: "traverse", params: param });
  console.log(this.$router, this.$router.history.length);
  currentIndex++;
},

Afterwards, simply connect the .disabled class to the currentIndex...
