总结

1. 发送的数据:

1.1 自定义(最灵活):用户自己输入,input的type为text,文本框/文本域,用户登录注册

1.2 预定义(最安全):由程序员/开发者已经写好,用户做选择,复选框/单选框/下拉菜单类似选择题

1.3 用户提交的方式:form标签的预置属性action=”xxx.php”,向服务器中xxx.php文件提交,method决定了提交方式

  • 1.3.1 method=”get”时,通过url提交,体现在网页跳转地址中
  • 1.3.2 method=”post”时,直接提交到服务器,可以在载荷中检查到,应该是对接接口的
  • 1.3.3 onsubmit=”return false”: 将表单的默认提交行为禁用

    1.4 <label>标签预置属性for用于绑定input中的id,页面中存在绑定关系,input中的type类型决定了什么类型的表单;

  • 1.4.1 单行文本框input的type类型为”text”,”password”等
  • 1.4.2 单选按钮input的type类型为”radio”
  • 1.4.3 复选框input的type类型为”checkbox”
  • 1.4.4 下拉列表用select标签(变量名name在此),下拉选项option(变量值value在此),selected disabled:表示默认首选但不可用,用来提示用户作用

    1.5 <button>标签默认提交,<button>=<button type="submit">

    1.6 多媒体标签<video>,<audio>

  • 1.6.1 controls:显示播放控件,布尔属性
  • 1.6.2 autoplay:自动播放
  • 1.6.3 poster:链接封面图片

    1.7 内联框架标签<iframe>-画中画

  • 1.7.1 <a>标签中target指向与iframe的变量名一直,即完成绑定
  • 1.7.2 a标签链接指定在iframe定义的区域中打开
