Method of dom/Elementdom/Element
var object = object.createControlRange();
Returns an object of type DOM NodeDOM Node
Returns a controlRange collection if sucessful or a null value otherwise.
This example creates a controlRange by using the createControlRange method.
oControlRange = document.body.createControlRange();
Creates a selection range object for control-based selection rather than text-based selection. If a controlRange already exists, createControlRange overwrites the existing element; otherwise, it returns a pointer to the element created. If there are currently controls selected in the text container, the control range is initialized with them; otherwise, it is created empty and controls need to be explicitly added to it. This is opposite of the text range, which defaults to the whole text container if there is no selection.
There are no standards that apply here.
