A string that contains the ID of the component to find.
(Optional) The component or element that contains the component to find.
A Component object that contains the component with the specified ID, if found; otherwise, null.
For details about the method that this shortcut represents, see Sys.Application.findComponent Method.
The following example uses the $find method to check whether a custom component exists and to notify the user if the component is missing.
function checkComponent() { if (!($find('MyComponent', div1))) { div1.innerHTML = 'MyComponent is not available.'; } }
