Creating custom code for pasting requires several steps.

Set event.returnValue=false in the onbeforepaste event to enable the Paste shortcut menu item.

Cancel the default behavior of the browser by including event.returnValue=false in the onpaste event handler. This guideline applies only to objects, such as the text box, that have a defined default behavior.

Specify a data format in which to paste the selection through the getData method of the clipboardData object.

Invoke the getData method in the onpaste event to execute custom code for pasting.
