Document: queryCommandEnabled() method

{{ApiRef("DOM")}}{{deprecated_header}}{{Non-standard_header}}

[!NOTE] Although the {{domxref("Document/execCommand", "execCommand()")}} method is deprecated, if you do decide to use it for reasons given on that page, you should consider checking the command's availability using queryCommandEnabled() to ensure compatibility.

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

Syntax

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
