'# Textarea 0.2.0

Used for inputting multi-line text information.

Basic Usage

You can use v-model for two-way binding of the input value and set placeholder text through placeholder.

<wd-textarea v-model="value" placeholder="Please enter your comment" />

const value = ref<string>('')

Disabled

Enable the disabled state by setting the disabled property.

<wd-textarea v-model="value" disabled></wd-textarea>

Read-only

Enable the read-only state by setting the readonly property.

<wd-textarea v-model="value" readonly></wd-textarea>

Clear Button

Enable the clear button by setting the clearable property, and implement character limit by setting show-word-limit and maxlength.

<wd-textarea v-model="value" :maxlength="120" clearable show-word-limit />

Show Clear Button on Focus

Set the clear-trigger property to control whether to show the clear button only when focused.

Note

Alipay Mini Program currently does not support the clear-trigger property, and in some cases, the clear button cannot be clicked. Please refer to this issue (Hoping it can be resolved soon, so I directly raised an issue in Ant's component library).

<wd-textarea clear-trigger="focus" v-model="value14" :maxlength="120" clearable show-word-limit />

Don't Auto Focus After Clearing

Set the focus-when-clear property to control whether to automatically focus after clicking the clear button.

<wd-textarea v-model="value" :focus-when-clear="false" :maxlength="120" clearable show-word-limit />

Auto Height

Enable auto height adjustment by setting the auto-height property.

<wd-textarea v-model="value" auto-height />

Prefix Icon

Set a prefix icon using prefix-icon, where the icon should be a class name from the icon section. If you need a custom icon that's not available, use the prefix slot instead.

<wd-textarea v-model="value" prefix-icon="dong"></wd-textarea>

Setting Label Title

Set a label title, which can be used with cell-group to create a cell display type. You can set the title width through label-width, which defaults to '33%'.

<wd-cell-group border>
  <wd-textarea label="Basic Usage" clearable v-model="value" placeholder="Please enter..." />
</wd-cell-group>

Required Style

When a label is set, you can set the required property to display the required style.

<wd-textarea v-model="value" placeholder="Please enter..." label="Required" required></wd-textarea>

Input Size

Modify the input size by setting size. When size is set to 'large', the font size is 16px.

<wd-textarea label="Basic Usage" size="large" v-model="value" placeholder="Please enter..." />

Error State

Set the error property to display the input value in red.

<wd-textarea v-model="value" placeholder="Please enter username" error />

Vertical Center

When a label title is set, it defaults to top alignment. Set the center property to vertically center the title and input box.

<wd-textarea label="Basic Usage" v-model="value" center />
