I m not sure what you mean by  myself     Any JavaScript function can be called by an event  but you must have some sort of event to trigger it   e g  On page load    lt body onload  myfunction     gt    Or on mouseover    lt table onmouseover  myfunction     gt    As a result the first question is   What do you want to do to cause the function to execute    After you determine that it will be much easier to give you a direct answer

Just drop   lt script gt  myfunction     lt  script gt    in the body where you want it to be called  understanding that when the page loads and the browser reaches that point  that s when the call will occur
