In Jquery, how can I set an event such that when user is browsing some pictures, and presses the left/right arrow key, it calls a function which can be used to show the previous/next photos? I only need to know how to check if the key pressed was the right/left arrrow key and ignore all other key preses.
The image will be in its own div.\
I've used this in the past. It works for me in the enviornments I've used (linux and windows with FF)
$(document).keypress( function(e) { if (e.keyCode === 37) { // left } else if (e.keyCode === 39) { // right } }); That being said, I'm not so sure connecting on the arrow keys is a good idea since a user could change text size and cause the scroll bar to appear. Arrowing would change the picture unexpectedly.
Use the jQuery keypress event like so:
$("input").keypress(function (e) { if (e.which == 32 || (65 <= e.which && e.which <= 65 + 25) || (97 <= e.which && e.which <= 97 + 25)) { var c = String.fromCharCode(e.which); $("p").append($("<span/>")) .children(":last") .append(document.createTextNode(c)); } else if (e.which == 8) { // backspace in IE only be on keydown $("p").children(":last").remove(); } $("div").text(e.which); }); I'm not sure which value will be present for left/right but a little experimenting with this script should get you going
