// In Firefox 2, arrow keys are unstable while DOM-manipulating
|
|
// operations are going on. Specifically, if an operation
|
|
// (computation that ties up the event queue) is going on (in the
|
|
// call-stack of some event, like a timeout) that at some point
|
|
// mutates nodes involved in the selection, then the arrow
|
|
// keypress may (randomly) move the caret to the beginning or end
|
|
// of the document. If the operation also mutates the selection
|
|
// range, the old selection or the new selection may be used, or
|
|
// neither.
|
|
|
|
// As long as the arrow is pressed during the busy operation, it
|
|
// doesn't seem to matter that the keydown and keypress events
|
|
// aren't generated until afterwards, or that the arrow movement
|
|
// can still be stopped (meaning it hasn't been performed yet);
|
|
// Firefox must be preserving some old information about the
|
|
// selection or the DOM from when the key was initially pressed.
|
|
// However, it also doesn't seem to matter when the key was
|
|
// actually pressed relative to the time of the mutation within
|
|
// the prolonged operation. Also, even in very controlled tests
|
|
// (like a mutation followed by a long period of busyWaiting), the
|
|
// problem shows up often but not every time, with no discernable
|
|
// pattern. Who knows, it could have something to do with the
|
|
// caret-blinking timer, or DOM changes not being applied
|
|
// immediately.
|
|
|
|
// This problem, mercifully, does not show up at all in IE or
|
|
// Safari. My solution is to have my own, full-featured arrow-key
|
|
// implementation for Firefox.
|
|
|
|
// Note that the problem addressed here is potentially very subtle,
|
|
// especially if the operation is quick and is timed to usually happen
|
|
// when the user is idle.
|
|
|
|
// features:
|
|
// - 'up' and 'down' arrows preserve column when passing through shorter lines
|
|
// - shift-arrows extend the "focus" point, which may be start or end of range
|
|
// - the focus point is kept horizontally and vertically scrolled into view
|
|
// - arrows without shift cause caret to move to beginning or end of selection (left,right)
|
|
// or move focus point up or down a line (up,down)
|
|
// - command-(left,right,up,down) on Mac acts like (line-start, line-end, doc-start, doc-end)
|
|
// - takes wrapping into account when doesWrap is true, i.e. up-arrow and down-arrow move
|
|
// between the virtual lines within a wrapped line; this was difficult, and unfortunately
|
|
// requires mutating the DOM to get the necessary information
