阻止HTML表单提交跳转页面，使用 Jquery Ajax 请求接口

1. HTML 表单

<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script><form action="" method="post" onsubmit="return save(this)">    手机号 <input type="text" name="mobile" autocomplete="off">    登录密码 <input type="text" name="password" autocomplete="off">    <button>提交</button></form>

2. Javascript 函数

/** * 提交表单 */function save(obj){    var formData = {};    var array = $(obj).serializeArray();    $.each(array, function() {        formData[this.name] = this.value;    });    console.log(formData)    $.ajax({        url: '',        type: 'post',        async: false,        data: formData,        success: res => {            console.log(res)        }    })    return false;}
