i'm having a problem with Galleria.
the following code:
<script type="text/javascript">
$(document).keypress(function(e)
{
switch(e.keyCode)
{
case 37: //press left arrow
$.galleria.prev();
break;
case 39: //press right arrow
$.galleria.next();
break;
}
});
</script>
won't work, it says:
$.galleria is undefined
if i use instead Galleria.prev() and Galleria.next()
then it says: Galleria.next is not a function, and the same fo prev.
i hope somebody with more experience can help me.
Thanks in advance,
Adam
galleria seems to have an attachKeyboard method, but i can't get that to work. but playing around with the code you have above, i managed to get arrow controls. try this:
<script>
//start galleria
Galleria.loadTheme('galleria.classic.js');
$('#galleria').galleria();
//obtain galleria instance - this might be the step you are missing
var gallery = Galleria.get(0);
//essentially what you had above
document.onkeyup = KeyCheck;
function KeyCheck(e) {
var KeyID = (window.event) ? event.keyCode : e.keyCode;
switch(KeyID) {
case 37: //press left arrow
gallery.prev();
break;
case 39: //press right arrow
gallery.next();
break;
}
}
</script>

How can give arrow key events in full page image slider, for example the below sample link -> https://www.htmllion.com/examples/pure-css-based-fullscreen-slider-demo.html.
I need the same layout with arrow key events.
Kindly help.
Use Keyboard events in Jquery. Based on the user click navigate the page
Using jQuery you can do something like this.
$(window).on('keyup', function(e){
console.log(e.keyCode); // log the keycode of the key pressed
switch(e.keyCode){
case 37:
console.log('Prev');
break;
case 38:
console.log('Up');
break;
case 39:
console.log('Next');
break;
case 40:
console.log('Down');
break;
}
});
You can add a keydown event to any element and call a function.
In the below example i have used an input text field to add a keydown event and it gives alert on pressing left or right arrow key
function myFunction(event) {
var keyVal = event.keyCode;
switch(keyVal)
{
case 37:
alert('Pressed left');
break;
case 39:
alert('Pressed right');
break;
}
}
<input type="text" onkeydown="myFunction(event)">
Still beginner here, please be gentle :)
I have a CSS-lighbox with 3 links: previous image, next image and exit. The links are like that:
<img src="images/prev.png" />
Then i have a KBD listening script:
function kbdNav(e) {
switch(e.keyCode) {
case 37:
// activate link "prev"
break;
case 39:
// activate link "next"
break;
case 27:
// activate link "exit"
break;
}
}
My goal is that when the KBD arrow is pressed (case 37) the link # prev.png gets activated, so that the lightbox image goes to the previous image. Same for the other 2 cases.
What method can be used for this?
First, select the anchor elements:
var prevLink = document.querySelector('.prev');
var nextLink = document.querySelector('.next');
var exitLink = document.querySelector('.exit');
Then edit the listener as follows:
function kbdNav (e) {
switch (e.keyCode) {
case 37:
prevLink.click();
break;
case 39:
nextLink.click();
break;
case 27:
exitLink.click();
}
}
Consider this topic closed. The solution works, but my HTML was quite messily structured.
I found a better solution with a pure JS gallery/lightbox.
I recently made a rudimentary html/css galery that is practicaly a table with next/previous buttons.The thing is I want to make it responsive to keyboard.Like if anyone hits the "left" button on keyboard it should go on the previous photo and if it hits the "right" button go on the next page.
I would love if you could make it with as less javascript/jquery as possible.I searched google for something like that but I haven't found none !
If you need any code of my website please let me know.
Please help !
You could capture the keyboard interaction using .on() and the keydown event, and decide what to do after the returned value like :
$(document).on("keydown", function (e) {
e.preventDefault();
var code = e.which || e.keyCode;
console.log(code)
if (code == 40) {
// down arrow pressed : do something
console.log("down arrow pressed")
}
});
See JSFIDDLE
The keyboard map of the navigation arrows are
// 37 = left arrow
// 38 = up arrow
// 39 = right arrow
// 40 = down arrow
EDIT : to avoid excessive use of if else if else, you could use switch (which performs better) like :
$(document).on("keydown", function (e) {
e.preventDefault();
var code = e.which || e.keyCode;
switch (code) {
case 37:
console.log("left arrow pressed")
break;
case 38:
console.log("up arrow pressed")
break;
case 39:
console.log("right arrow pressed")
break;
case 40:
console.log("down arrow pressed")
break;
default:
return false
}
});
See updated JSFIDDLE
JFK's answer is correct, but I extended that a little
$(document).on("keydown", function (e) {
var code = e.which || e.keyCode;
if (code == 40 || code == 39) { // down & right
// replace selector with your button id/class
$('.btn-next').click();
} else if (code == 38 || code == 37) { // up & left
// replace selector with your button id/class
$('.btn-previous').click();
}
});
The code simulates a click on the next/previous buttons so you are able to place any code which should happen when clicking or key pressing only once.
I am having problems with a jquery slideshow where I want to bind next/right to make the images jump forwards/back.
I used the following code to attempt to do it but it simply refreshes the page.
<script>
$(function() {$(document).keyup(function(e) {
switch(e.keyCode) { case 37 : window.location = $('#prev a').attr('href'); break;
case 39 : window.location = $('#next a').attr('href'); break; }});});
</script>
The I was attempting to call were:
<a href='#' id='prev' onclick='show_image($prev); return false;'>
and
<a href='#' id='next' onclick='show_image($next); return false;'>
Does anyone know an easy way to cut out the middle man and simply bind left/right to the onclick event for each?
Anyhelp would be much appreciated!
This should work:
$(function() {
$(document).keyup(function(e) {
switch (e.keyCode) {
case 37:
$('#prev a')[0].onclick();
break;
case 39:
$('#next a')[0].onclick();
break;
}
});
});
Just call the onclick event handler of the left or right button based on which key you pressed.
$(function() {
$(document).keyup(function(e) {
switch (e.keyCode) {
case 37:
$('#prev').click();
break;
case 39:
$('#next').click();
break;
}
});
});
I don't know much about how it works. My guess is JavaScript, but anyway.
When you go to your dashboard in Tumblr you can go back and forth between pages in your feed with your keyboard. ← to go forward to newer posts and → to go to older posts.
Can someone help me figure out how they do this.
Well, what you have do is set up a "keyup" event listener for your document element that reads which key your user pressed, then execute an action if the keycode matches the code for your left or right keys.
The "left" key's keycode is 37. the right is 39. So the listener for the "left" key you would set up is this:
document.onkeyup = function(e){
if (e.keyCode == 37) { //"left" key.
//your code
}
if (e.keyCode == 39) { //"right" key.
//your code
}
}
Figured it out:
<script type="text/javascript">
document.onkeyup = KeyCheck;
function KeyCheck(e)
{
var KeyID = (window.event) ? event.keyCode : e.keyCode;
switch(KeyID)
{
case 37:
window.location = "{PreviousPage}";
break;
case 39:
window.location = "{NextPage}";
break;
}
}
</script>
