Selection.isCollapsed
This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
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
