doLogin(localStorage.username, localStorage.password, this, function (res, msg) {
if (res) {
this.$store.commit({
type: "login",

});this.$store the this here points to incorrect how to bind the outer this to the callback function
use the arrow function
const doLogin = function (username, password, v, callback) {
};
doLogin(localStorage.username, localStorage.password, this, (res, msg) => {
if (res) {
this.$store.commit({
type: 'login',
