在web表單中, HTML元素<option>用于定義在<select><optgroup><datalist>元素中包含的項(xiàng)。<option> 可以在彈出窗口和 html 文檔中的其他項(xiàng)目列表中表示菜單項(xiàng)。

內(nèi)容類別

無(wú)

允許的內(nèi)容

帶有最終轉(zhuǎn)義字符(例如 &eacute;)的文本

標(biāo)記省略

開(kāi)始標(biāo)記是必需的。如果此元素緊接著是另一個(gè) <option> 元素或<optgroup>, 或者父元素沒(méi)有其他內(nèi)容, 則結(jié)束標(biāo)記是可選的。

允許的父元素

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

允許的ARIA角色

無(wú)

DOM 接口

HTMLOptionElement

屬性

此元素包括全局屬性。

disabled如果設(shè)置了這個(gè)布爾屬性,選項(xiàng)就不是可選的。瀏覽器通常會(huì)將這種控件顯示為灰色,并且不再接受任何瀏覽器事件,例如鼠標(biāo)點(diǎn)擊或者焦點(diǎn)相關(guān)的事件。如果這個(gè)屬性沒(méi)有設(shè)置,如果元素的祖先是禁用的<optgroup>元素,元素仍然是禁用的 。

label這個(gè)屬性是用于表示選項(xiàng)含義的文本。如果 label 屬性沒(méi)有定義,它的值就是元素文本內(nèi)容。

selected如果存在, 則這個(gè)布爾屬性表明,這個(gè)選項(xiàng)初始被選中。如果 <option> 元素是<select>元素的后繼,并且它的 multiple屬性沒(méi)有設(shè)置,這個(gè)<select>元素只有一個(gè)<option> 元素可以擁有selected 屬性。

value這個(gè)屬性的內(nèi)容代表這個(gè)選項(xiàng)選中的話,提交給表單的值。如果省略了這個(gè)屬性,值就從選項(xiàng)元素的文本內(nèi)容中獲取。

示例

請(qǐng)見(jiàn)<select>示例。
