在web表单中, HTML元素<option>用于定义在<select><optgroup><datalist>元素中包含的项。<option> 可以在弹出窗口和 html 文档中的其他项目列表中表示菜单项。

内容类别

允许的内容

带有最终转义字符(例如 &eacute;)的文本

标记省略

开始标记是必需的。如果此元素紧接着是另一个 <option> 元素或<optgroup>, 或者父元素没有其他内容, 则结束标记是可选的。

允许的父元素

A <select>, an <optgroup> or a <datalist> element.

允许的ARIA角色

DOM 接口

HTMLOptionElement

属性

此元素包括全局属性。

disabled如果设置了这个布尔属性,选项就不是可选的。浏览器通常会将这种控件显示为灰色,并且不再接受任何浏览器事件,例如鼠标点击或者焦点相关的事件。如果这个属性没有设置,如果元素的祖先是禁用的<optgroup>元素,元素仍然是禁用的 。

label这个属性是用于表示选项含义的文本。如果 label 属性没有定义,它的值就是元素文本内容。

selected如果存在, 则这个布尔属性表明,这个选项初始被选中。如果 <option> 元素是<select>元素的后继,并且它的 multiple属性没有设置,这个<select>元素只有一个<option> 元素可以拥有selected 属性。

value这个属性的内容代表这个选项选中的话,提交给表单的值。如果省略了这个属性,值就从选项元素的文本内容中获取。

示例

请见<select>示例。
