在默认打开的v形对话框中将焦点设置在v-btn上

<template>
  <v-dialog v-model="dialog">
    <v-btn ref="myButton">Click me</v-btn>
  </v-dialog>
</template>

<script>
export default {
  data() {
    return {
      dialog: true
    };
  },
  mounted() {
    this.$nextTick(() => {
      this.$refs.myButton.$el.focus();
    });
  }
};
</script>
