#html5 valid

contenteditable 属性用于指定 HTML 元素是否可编辑。其有效值包括 'true'、'false' 和 'inherit'。当设置为 'inherit' 时，元素将继承父元素的 contenteditable 状态；'true' 使其变为可编辑，'false' 则反之。不设置该属性或设置为 'inherit' 相同。

问题

What values can I choose for the attribute contenteditable.

回答1:

It can contain:

true

false

inherit

Quoting:

The contentEditable DOM attribute, on

getting, must return the string "true"

if the content attribute is set to the

true state, false" if the content

attribute is set to the false state,

and "inherit" otherwise. On setting,

if the new value is case-insensitively

equal to the string "inherit" then the

content attribute must be removed, if

the new value is case-insensitively

equal to the string "true" then the

content attribute must be set to the

string "true", if the new value is

case-insensitively equal to the string

"false" then the content attribute

must be set to the string "false", and

otherwise the attribute setter must

raise a SYNTAX_ERR exception.

回答3:

There is no "inherit" value. Inherit is implied by omitting the attribute. The attribute has 3 values and 3 states. Values are empty string, true and false. States are true, false and inherit.

In there a inherit value for the contenteditable attribute?
