如何从用户那里获取登录凭据并将其作为 JavaScript 中的 object 推送到数组中？

Question

Hello I want to store username and password as an object in array. As of this time I have this code:

var loginCred = [
{
    username: "janhaxe23",
    password: "HaxeJan23"
}];

function LogIn() {
var username = document.getElementById('username').value;
var password = document.getElementById('password').value;

for(i = 0; i < loginCred.length; i++) {
    if(username == loginCred[i].username && password == loginCred[i].password) {
        window.alert("Login Successfully. Welcome "+ username);
        return;
    }
}
window.alert("Incorrect login credentials. Please try again.");}

Instead of creating an object directly in JS file I want the user to input their login credentials by clicking the "Register" button. Thank you.

Answer 1

function register(){
 var username = document.getElementById('username').value;
 var password = document.getElementById('password').value;

 loginCred.push({
   username: username,
   password: password
 })

}

You can push values to an array like this
