unicode-bidi Attribute | unicodeBidi参数属性

Sets or retrieves the level of embedding with respect to the bidirectional algorithm.

HTML { unicode-bidi : sEmbedLevel }
Scripting object.style.unicodeBidi [ = sEmbedLevel ]

DHTML可能的值

sEmbedLevel String that specifies or receives one of the following values:
normal Default. Element does not open an additional level of embedding. For inline elements, implicit reordering works across element boundaries.
embed Element opens an additional level of embedding. The value of the direction property specifies the embedding level. reordering is implicit inside the element.
bidi-override same as the embed value, except that, inside the element, reordering is strictly in sequence according to the direction property. This value overrides the implicit bidirectional algorithm.
The property is read/write for all objects except the following, for which it is read-only: currentStyle. The property has a default value of normal. The Cascading Style Sheets (CSS) attribute is not inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see about dynamic properties.

remarks

the unicodebidi property is used with the direction property.
the unicode bidirectional algorithm automatically reverses embedded character sequences according to their inherent direction. for example, the base direction of an english document is left-to-right. if portions of a paragraph within the document contain a language with a right-to-left reading order, the direction of that language displays correctly right-to-left. the user agent applying the bidirectional algorithm correctly reverses the language direction.
