Range.collapse( ) — make one boundary point equal to the other
DOM Level 2 Range
void collapse(boolean toStart)
throws DOMException;toStart
If this argument is true, the method sets the end
point of the range to the same value as the starting point.
Otherwise, it sets the starting point to the same value as the end
point.
This method sets one boundary point of the range to be the same as
the other point. The point to be modified is specified by the
toStart argument. After this method
returns, the range is said to be “collapsed”: it
represents a single point within a document and has no content. When
a range is collapsed like this, its collapsed
property is true.
