Toggle Button 切换按钮

切换按钮组件可用于对相关选项进行分组。

为了强调组合之间的关联,每一组切换按钮应该共享一个容器。 当给定切换按钮的 value 属性时,ToggleButtonGroup 就可以控制其子按钮的选择状态(selected state)。

唯一的选择

在唯一的选择中,选择一个选项就会取消其他的选择状态。

In this example, text justification toggle buttons present options for left, center, right, and fully justified text (disabled), with only one item available for selection at a time.

Note: Exclusive selection does not enforce that a button must be active. For that effect see enforce value set. For that effect see enforce value set.

多选

Multiple selection allows for logically-grouped options, like bold, italic, and underline, to have multiple options selected.

Size 大小

For larger or smaller buttons, use the size prop.

<ToggleButtonGroup size="small" {...control}>
  {children}
</ToggleButtonGroup>
<ToggleButtonGroup {...control}>{children}</ToggleButtonGroup>
<ToggleButtonGroup size="large" {...control}>
  {children}
</ToggleButtonGroup>

Color 颜色

<ToggleButtonGroup
  color="primary"
  value={alignment}
  exclusive
  onChange={handleChange}
>
  <ToggleButton value="web">Web</ToggleButton>
  <ToggleButton value="android">Android</ToggleButton>
  <ToggleButton value="ios">iOS</ToggleButton>
</ToggleButtonGroup>

垂直排列的按钮

The buttons can be stacked vertically with the orientation prop set to "vertical".

<ToggleButtonGroup
  orientation="vertical"
  value={view}
  exclusive
  onChange={handleChange}
>
  <ToggleButton value="list" aria-label="list">
    <ViewListIcon />
  </ToggleButton>
  <ToggleButton value="module" aria-label="module">
    <ViewModuleIcon />
  </ToggleButton>
  <ToggleButton value="quilt" aria-label="quilt">
    <ViewQuiltIcon />
  </ToggleButton>
</ToggleButtonGroup>

强制设置值

If you want to enforce that at least one button must be active, you can adapt your handleChange function.

const handleAlignment = (event, newAlignment) => {
  if (newAlignment !== null) {
    setAlignment(newAlignment);
  }
};

const handleDevices = (event, newDevices) => {
  if (newDevices.length) {
    setDevices(newDevices);
  }
};

单独的切换按钮

<ToggleButton
  value="check"
  selected={selected}
  onChange={() => {
    setSelected(!selected);
  }}
>
  <CheckIcon />
</ToggleButton>

ARIA

  • ToggleButtonGroup 具有 role="group"。 请您提供一个可访问的标签,标签包含 aria-label="label"aria-labelledby="id"<label>
  • ToggleButton 根据按钮的状态来设置 aria-pressed="<bool>"。 您应该用 aria-label 标记每个按钮。

键盘输入

At present, toggle buttons are in DOM order. Navigate between them with the tab key. The button behavior follows standard keyboard semantics. Navigate between them with the tab key. The button behavior follows standard keyboard semantics.
