Usage
ts
import { useTextDirection } from '@vueuse/core'
const dir = useTextDirection() // Ref<'ltr' | 'rtl' | 'auto'>
import { useTextDirection } from '@vueuse/core'
const dir = useTextDirection() // Ref<'ltr' | 'rtl' | 'auto'>
By default, it returns rlt direction when dir rtl is applied to the html tag, for example:
html
<!--ltr-->
<html> ... </html>
<!--rtl-->
<html dir="rtl"> ... </html>
<!--ltr-->
<html> ... </html>
<!--rtl-->
<html dir="rtl"> ... </html>
Options
ts
import { useTextDirection } from '@vueuse/core'
const mode = useTextDirection({
selector: 'body'
}) // Ref<'ltr' | 'rtl' | 'auto'>
import { useTextDirection } from '@vueuse/core'
const mode = useTextDirection({
selector: 'body'
}) // Ref<'ltr' | 'rtl' | 'auto'>
