Vue 的方法中调用另一个方法

<script>
export default {
  name: "Login",
  data() {
    return {
      email: "",
      code: "",
      isSentCode: false,
    };
  },
  methods: {
    sendCodeBtnAction: function() {
    },
    nextBtnAction: function() {
      if (!this.isSentCode) {
        this.$options.methods.sendCodeBtnAction.bind(this)();
      //或者直接用这个
      //this..sendCodeBtnAction();
      } 
    }
  }
};
</script>
