- emmet
- 指令之间不能有空格
- class如果设置了并列多项,用
.
连接每一个,第一个前面也有.
- 表单
- 使用 autofocus 设置默认焦点位置
- 只有默认名称没有值的是布尔属性:required, disabled,checked, selected
- id 属性前端操作用,不传值到后台
- name 属性是提交到服务器上的变量名,一组单选按框的 name 必须相同
- 单选框可以设置默认 checked 的值,用于对应 label for 绑定,点击 label 值会复位
- 复选框需要返回多个值,name 不能相同,需要设置成数组:
name[]
- 复选框最好设置默认值,否则会传回空数组
- input button 按键显示内容为 input value 属性,不在input标签外
- option 的default “请选择”选项可以用属性
selected disabled
来禁用且让用户要选择一项
- 表单的问题点
- 复选框选择
客户1、客户2
或者客户1、客户3
传给后台的数组似乎是一样的,都是 array(2) { [0]=> string(2) “on” [1]=> string(2) “on” },这样就不知道如何区分了?
