data is like this
data () {
return {
username: "",
pw: "",
pw2: ""
}
} then in a method of methods, is it wrong to deconstruct the assignment like this? this points to the current component. Can"t I print the username to show that it is empty
const {username, pw, pw2} = this this deconstruction can only be used in vue to obtain assignments that cannot be operated because it is a value
const {username, pw, pw2} = this
username = '123'// if you're just using it for printing, maybe username is asynchronously assigned
this.username = ''
const {username, pw, pw2} = this
consloe.log(username) //
has actually been deconstructed. It is empty because your initial value is empty. You can set a username value to see
.is already an empty string. If you can't get it, it should be undefined
