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

Syntax

isEnabled = document.queryCommandEnabled(command);

Parameters

command
The command for which to determine support.

Return value

Returns a Boolean 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

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

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