getElementData api - cornerstonejs/cornerstone GitHub Wiki

The getElementData api call is used to access element specific data for an enabled element. If no data exists for this dataType, an empty object is created.

function _getElementData_(element, dataType);

Parameters:

• element - the DOM element that has been enabled (DOM node)
• dataType - a unique string identifying this data type. We recommend using a GUID generator to avoid conflicts with other tools that might happen to use the same name (String)

Returns: a Javascript object for this dataType
