对象构造函数，将信息从表单传递到HTML

function Person(name, age) {
    this.name = name;
    this.age = age;
}

var person1 = new Person("Alice", 30);

<form id="myForm">
    <input type="text" id="name" placeholder="Enter your name">
    <input type="number" id="age" placeholder="Enter your age">
    <button type="button" onclick="submitForm()">Submit</button>
</form>

function Person(name, age) {
    this.name = name;
    this.age = age;
}

function submitForm() {
    var name = document.getElementById('name').value;
    var age = document.getElementById('age').value;

    var person = new Person(name, age);

    // 现在你可以使用person对象来操作数据
    console.log(person.name + " is " + person.age + " years old.");
}

function submitForm() {
    var name = document.getElementById('name').value;
    var age = document.getElementById('age').value;

    if (name && age) {
        var person = new Person(name, age);
        console.log(person.name + " is " + person.age + " years old.");
    } else {
        alert("Please fill out all fields.");
    }
