Javascript 如何向特定区域/部门写信?

Javascript 如何向特定区域/部门写信?,javascript,html,document.write,Javascript,Html,Document.write,我的代码: <button type="button" onclick="ayee()" value="click" /> <script> function ayee(){ confirm("Ready to play?"); var age = p

我的代码:

<button type="button" onclick="ayee()" value="click" />
                    <script>                        
                    function ayee(){
                        confirm("Ready to play?");
                        var age = prompt("How old are you?");
                        if (age >= 18) {
                            document.write("Let's get started then!");
                        }else{
                            document.write("You're under 18? Be careful out there....");
                        }
                    }
                    </script>

函数ayee(){
确认(“准备好玩了吗?”);
var age=prompt(“你多大了?”);
如果(年龄>=18岁){
文档。写下(“让我们开始吧!”);
}否则{
记录。写下(“你不满18岁?在外面要小心……”);
}
}

基本上,我使用document.write()来编写JS的响应,但我想将响应推送到某个分区或区域,这样我就可以保留页面其余部分的格式。

不要使用
文档。编写
。相反,创建一个div,将输出放在其中,并给它一个id:

我将被更新

然后在JS代码中使用:

function ayee() {
    confirm("Ready to play?");
    var age = prompt("How old are you?"),
        // Get a reference to the element we want to update
        el = document.getElementById('result'),
        message;

    // Check the age and set the message variable based on that
    if (age >= 18) {
        message = "Let's get started then!";
    } else {
        message = "You're under 18? Be careful out there....";
    }
    // Update the content of the element with the message
    el.innerHTML = message;
}

        message = "You're under 18? Be careful out there....";
    }
    // Update the content of the element with the message
    el.innerHTML = message;
}

首先在要写入数据的分区上放置一个id属性

<div id="div-id"></div>

你能解释一下el和s以及el.innerHTML=s的作用吗?这些都是非常基本的东西,我已经用解释更新了帖子。你能解释一下el和s以及el.innerHTML=s的作用吗?这些都是非常基本的东西,我用解释更新了帖子。
