Document: queryCommandEnabled() method

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The Document.queryCommandEnabled() method reports whether or not the specified editor command is enabled by the browser.

Syntax

document.queryCommandEnabled(command)

Parameters

command: The command for which to determine support.

Return value

Returns a boolean value which is true if the command is enabled and false if the command isn't.

Notes

For 'cut' and 'copy' commands the method only returns true when called from a user-initiated thread.
The 'paste' command return false not only if the feature is unavailable, but also if the script calling it has insufficient privileges to perform the action.

Example

const flg = document.queryCommandEnabled("SelectAll");

if (flg) {
  document.execCommand("SelectAll", false, null); // command is enabled, run it
}

Specifications

This feature is not part of any current specification. It is no longer on track to become a standard.
