使用jQuery实现Form表单提交操作

<form id="myForm" action="/submit" method="POST">
    <label for="name">姓名：</label>
    <input type="text" id="name" name="name">
    <label for="email">邮箱：</label>
    <input type="email" id="email" name="email">
    <button type="submit" id="submitBtn">提交</button>
</form>

$(document).ready(function() {
    $("#myForm").submit(function(event) {
        // 阻止表单默认提交行为
        event.preventDefault();
        // 获取表单数据
        var formData = $("#myForm").serialize();
        // 发起POST请求提交表单数据
        $.ajax({
            type: "POST",
            url: "/submit",
            data: formData,
            success: function(response) {
                // 处理提交成功的响应
                console.log("提交成功");
            },
            error: function(error) {
                // 处理提交失败的情况
                console.log("提交失败");
            }
        });
    });
});

<form id="registrationForm" action="#" method="POST">
    <label for="name">姓名：</label>
    <input type="text" id="name" name="name" required>
    <label for="email">邮箱：</label>
    <input type="email" id="email" name="email" required>
    <label for="password">密码：</label>
    <input type="password" id="password" name="password" required>
    <button type="submit" id="submitBtn">注册</button>
</form>
<div id="resultMessage"></div>

$(document).ready(function() {
    $("#registrationForm").submit(function(event) {
        event.preventDefault();
        
        var formData = $("#registrationForm").serialize();
        
        $.ajax({
            type: "POST",
            url: "/register",
            data: formData,
            success: function(response) {
                $("#resultMessage").text("注册成功！");
                $("#registrationForm")[0].reset(); // 重置表单
            },
            error: function(error) {
                $("#resultMessage").text("注册失败，请重试。");
            }
        });
    });
});
