Returns the specified Component object. This member is static and can be invoked without creating an instance of the class.
var o = Sys.Application.findComponent(id, parent)
Arguments
id
A string that contains the ID of the component to find.parent
(Optional) The component or element that contains the component to find.
Return Value
A Component object that contains the component requested by ID, if found; otherwise, null.
Remarks
Use the findComponent method to get a reference to a Component object that has been registered with the application through the addComponent method. If parent is not specified, the search is limited to top-level components. If parent represents a Component object, the search is limited to children of the specified component. If parent is a DOM element, the search is limited to child components of the specified element.
The findComponent method can also be invoked by using the $find shortcut method.
Example
The following example uses the findComponent method to check whether a custom component exists and to notify the user if it is missing.
function checkComponent() {
if (!($find('MyComponent', div1))) {
div1.innerHTML = 'MyComponent is not available.';
}
}
