I'm looking into creating an extension that acts like the find bar,
but only searches link. (Like FireFox's Quick Find (links only))
It seems possible, but my current implementation is clunky.
Questions:
1) Does functionality like this already exist in chrome, or via an
extension?
2) Is it possible to use the existing find bar, or do I need to roll
my own in DOM?
3) I want to use the same shortcut key as FireFox ('). However, my
current implementation is a bit yucky because it captures apostrophes
in cases where it's incorrect (e.g, typing in a text box, or if the
root page is already handling apostrophe). Right now I'm using
onkeypress on document.
Any suggestions on how to be aware if no other handler has responded
to the key? Ignoring textarea/input is okay, but I would prefer if I
could exclude all keypresses if the webpage has already bound to
apostrophe.
The shell of my code (just the custom find bar, no find behavior):
===
var CODE_ESCAPE = 27;
var CODE_APOSTROPHE = 39;
var SEARCH_BOX = '<div id="linkfind_div"
style="display:none;position:absolute;top:0;right:0;"><input
type=text></div>'
function hide() {
if (!enabled) return;
enabled = false;
$(document).keypress(showOnApos);
$('#linkfind_div').hide();
}
function show() {
if (enabled) return;
enabled = true;
$(document).unbind('keypress', showOnApos);
$('#linkfind_div').show();
$('#linkfind_div input').focus();
}
function showOnApos(event) {
if (event.keyCode == CODE_APOSTROPHE) {
show();
}
}
function hideOnEsc(event) {
if (event.keyCode == CODE_ESCAPE) {
hide();
}
}
// main entry point
var enabled = false;
var searchBox = null;
$('body').append(SEARCH_BOX);
$('#linkfind_div input').blur(hide);
$('#linkfind_div input').keyup(hideOnEsc);
$(document).keypress(showOnApos);
