Check the Browser compatibility table carefully before using this in production.
The Selection.isCollapsed
read-only property returns a Boolean
which indicates whether or not there is currently any text selected; That is to say that the selection's start and end points are at the same position in the content.
Keep in mind that a collapsed selection may still have one (or more, in Gecko) Range
s, so Selection.rangeCount
may not be zero. In that scenario, calling a Selection
object's getRangeAt()
method may return a Range
object which is collapsed.
Syntax
bool = sel.isCollapsed
