Hi,
I'm writing a plugin for jQuery for catching 2 succesive keypresses.
I'll paste the plugin I wrote below .
It doesn't work on Opera . The Developer tools of Opera gave
no errors and I can't find any problems, it just doesn't work.
(I've used Opera 10.0).
So it only works on Firefox (tested on 3.0.14).
I'm curious if there is a way to find out why it's not working on
Opera and to fix it.
Here's the code:
26 /*
27 * this is a plugin for binding double key combinations to some
callback
28 * it works by storing the first_press in the global jQuery
namespace , a boolean value which indicates
29 * the first key has already been pressed (but it's updated to
'false' in delay time.
30 * in teh meanwhile if someone presses the secondKey and the
$.first_press is true , the callback will execute
31 * with the $(this) passed as parameter so it ca modify it
32 */
33
34 $.fn.keypressTwice = function(firstKey,secondKey,actualCallback) {
35 var stuff = $(this);
36 var delay = 1000;
37 stuff.keypress(function(e){
38 if($.first_press) {
39 if(String.fromCharCode(e.charCode)==secondKey) {
40 //alert('secondKey');
41 actualCallback(stuff);
42 $.first_press = false;
43 }
44 } else if(String.fromCharCode(e.charCode)==firstKey) {
45 //alert('firstKey');
46 $.first_press = true;
47 window.setTimeout(function() {
48 $.first_press= false;
49 }, delay);
50 };
51 e.stopPropagation();
52 });
53 }
Thanks for taking the time to read this.
Best regards,
Stefan
