一直在思考为什么ajax可以传数据到服务端

jsp文件

 


"form" action="" method="post" >
class="form-group"> "text" name="username" placeholder="用户名..." class="form-username form-control" id="registerInputUsername">
class="form-group"> "password" name="password" placeholder="密码..." class="form-password form-control" id="registerInputPassword">
class="form-group">

重点在于input里的name标签,这个标签决定表单的数据能否提交到服务器,如果没有这个标签,那么将无法提交。

当绑定登录按钮点击事件后,每次点击,分析HTTP请求会发现

General
  Request URL:http://localhost:8080/register   Request Method:POST   Status Code:200 OK   Remote Address:127.0.0.1:8080   Referrer Policy:no-referrer-when-downgrade Response Headers   Content-Language:zh-CN   Content-Length:6023   Content-Type:text/html;charset=UTF-8   Date:Tue, 17 Oct 2017 14:48:05 GMT   Server:Apache-Coyote/1.1 Request Headers   Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8   Accept-Encoding:gzip, deflate, br   Accept-Language:zh-CN,zh;q=0.8   Cache-Control:max-age=0   Connection:keep-alive   Content-Length:30   Content-Type:application/x-www-form-urlencoded   Cookie:Idea-d08954fc=4c071045-2571-42f1-be8f-4c1f2be8be8a; Webstorm-167e2d55=b999dc51-0bbe-4cc2-a840-95e8b7fbeedc;

Form Data   username:admin   password:123456

Form Data,指的是页面有表单的情况下的HTTP请求,可以看成是键值对,username,password均由input标签里面的name属性所指定,与其他的类似AJAX里的data没有任何关系
