Function code triggered by vue leaving the current page

I won't talk too much, let's just look at the code ~

destroyed(){
 console.log(' Destruction ')
}

Additional knowledge: Execute functions after entering and leaving the routing page in vue

Go to the Routing page

mounted(){
   this.$nextTick(()=>{
    show();
  })
}

Execute the function after leaving the routing page

destroyed: function () {
      console.log(" I've already left! ");
  this.stopTimer();
 },

Note: destroyed is at the same level as methods and mounted

mounted(){
  this.startTimer();
},
// Execute after leaving the current page 
destroyed: function () {
  this.stopTimer();
},
