Guide on implementing Vuetify Component Slot Function

Can someone help me figure out how to implement the v-alert dismissible component with additional functionality when the close button is clicked? According to the documentation, there is a function called toggle in the close slot that allows you to "Toggles the alert’s active state. Available in the close slot and used as the click action in dismissible."

https://vuetifyjs.com/en/api/v-alert/#functions

https://vuetifyjs.com/en/api/v-alert/#slots-close

Here's what I have tried so far without success:

<template>
  <div id="app">
    <v-app>
      <v-alert dismissible v-model="message">
        {{ message }}
        <template v-slot:close="{ toggle }">
          <v-btn color="primary" dark @click="myFunction"> Dismiss </v-btn>
        </template>
      </v-alert>
    </v-app>
  </div>
</template>

<script>
export default {
  name: "App",
  data: () => ({
    message: "The message",
  }),
  methods: {
    myFunction() {
      console.log("do something before dismiss");
    },
  },
};
</script>

Answer №1

If you're looking to implement a toggle function, one approach is to pass the function to your own custom function and then invoke it as needed.

Check out this example on CodePen for reference

<div id="app">
    <v-app>
      <v-alert dismissible v-model="myAlertModel">
        {{ message }}
        <template v-slot:close="{ toggle }">
          <v-btn  color="primary" dark @click="myFunction(toggle)"> Dismiss </v-btn>
        </template>
      </v-alert>
    </v-app>
  </div>

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
   data: () => ({
    message: "The message",
     myAlertModel: true,
  }),
  methods: {
    myFunction(dismissFn) {
      console.log("Performing actions before dismissal");
      dismissFn();
      
    },
  
  },
})

Another issue to note is that the v-model in this case should be bound to a boolean value, not a string.
