新对象内部的JS对象分解

Question

I'm trying to achieve this with object destructuring but can't quite figure out the right syntax:

Without destructuring:

  this.$store.dispatch('user/login', {
    username: this.username,
    password: this.password
  })

With destructuring (doesnt work):

  this.$store.dispatch('user/login', {
    { username, password } = this
  })

What's the right syntax here?

Answer 1

I think you're confused. There is nothing to "destructure" here - your dispatch function simply takes an object parameter with 2 properties ( username and password ).

You could define this object before calling it like:

var input = {username:this.username,password:this.password};
this.$store.dispatch('user/login', input);

Or, as your current object has the right properties you could simply pass this

this.$store.dispatch('user/login', this);

It's worth going though the docs here on destructuring to understand it.
