Remarks
For releaseCapture to have an effect, you must set mouse capture through the setcapture method.
you can invoke the releasecapture method on the document object. the releasecapture method makes it unnecessary to determine which element has capture to programmatically release it. other actions that release document capture include displaying a modal dialog box and switching focus to another application or browser window.
