canAcceptCommand()

Adobe Dreamweaver calls the canAcceptCommand() function for each menu item in the MyMenu menu to determine whether it should be enabled or disabled. In the MyMenu.htm file, the canAcceptCommand() function checks the value of arguments[0] to determine whether Adobe Dreamweaver is processing a Redo menu item or an Undo menu item. If the argument is "undo", the canAcceptCommand() function calls the enabler function dw.canUndo() and returns the returned value, which is either true or false. Likewise, if the argument is "redo", the canAcceptCommand() function calls the enabler function dw.canRedo() and returns its value to Adobe Dreamweaver. If the canAcceptCommand() function returns the value false, Adobe Dreamweaver dims the menu item for which it called the function. The following example shows the code for the canAcceptCommand() function:

function canAcceptCommand(){ var selarray; if (arguments.length != 1) return false; var bResult = false; var whatToDo = arguments[0]; if (whatToDo == "undo") { bResult = dw.canUndo(); } else if (whatToDo == "redo") { bResult = dw.canRedo(); } return bResult;}
