        function onDialogBeforeOpen(args) {
            if (args.requestType == "dialogBeforeOpen") {
                alert("dialog before open event triggered");
            }
        }
</script>

The client-side event DialogOpen can be used to define the specific actions after the dialog window open as shown in the following code example.

                alert(args.targetText);
            }
        }

The following code example used to define some actions after the dialog closing by using the client-side event DialogClose.

        function onDialogClose(args) {
            if (args.requestType == "dialogClose") {
                alert(args.updatedText);
            }
        }
</script>

It is possible to predict the error word details before starting the spell check operations through dialog mode by using the client side event Start. The below code example describes the above behavior.

            spellObj.validate();
        }
</script>

NOTE

For default menu items, the id must be defined the same as mentioned in the above code example – as we have processed the menus based on this id within our source.

Apart from the default available options, it is also possible to add custom menu options to the context-menu list.
