queryCommandIndeterm method (document, TextRange, ...)

Browser support:

Returns whether the specified command is in an indeterminate state.

Indeterminate state means that the queryCommandState method cannot detect the current state of the command, therefore it will return null.

Syntax:

object.queryCommandIndeterm (commandIdentifier);

You can find the related objects in the Supported by objects section below.

Required. A case-insensitive string that specifies the name of the command. See command identifiers for more information.

Boolean. One of the following values:

false	The specified command is in indeterminate state.
true	The specified command is not in indeterminate state.

            }

                }
                else {
