javascript - keyboard scrolling on focused div in webkit -

-

i've got little jquery plugin. there images in vertically scrollable div. can click on div , scroll using arrow keys.

if take @ example, can see want observe if arrow key right/left pressed , if so, jump next image. in firefox , ie, keyup() event being called, , in safari , chrome it's not.

i have encountered several strange scrolling , focus behaviours in webkit browsers, don't know why keyup() event not being fired. if have idea, please let me know.

just add tabindex attribute div-element , work. kind of hack make otherwise not focusable element focusable, input or button.

depending on value given tabindex, behave diffrently:

  • 0 allow focus element keyboard arrows , tab key
  • -1 disable tabbing, still focusable
  • anything greater 0 allow prioratize tab focusing, 1 has highest priority

i've updated jsfiddle demo accordingly.
