jquery input number
Solution 1
$("#minus,#plus").click(function(){
var value = parseInt($(".numbertype").val(), 10);
$(".numbertype").val(value + $(this).is("#minus") ? -1 : 1);
});
I just wanted to see how to do it myself. Here's a toggle that will keep going on mouse down:
var i = null;
var d = 0;
var $numbertype = null;
function ToggleValue() {
$numbertype.val(parseInt($numbertype.val(), 10) + d);
}
$(function() {
$numbertype = $(".numbertype");
$("#minus,#plus").mousedown(function() {
d = $(this).is("#minus") ? -1 : 1;
i = setInterval(ToggleValue, 100);
});
$("#minus,#plus").on("mouseup mouseout", function() {
clearInterval(i);
});
});

If you substitute the images you want for the plus/minus buttons, this would work:
<span class="plusminusunit">
<span class="minus">-</span>
<input type="number" class="numbertype" value="10">
<span class="plus">+</span>
</span>
$(".plus").click(function() {
var item = $(this).closest(".plusminusunit").find("input");
item.val(Number(item.val()) + 1);
});
$(".minus").click(function() {
var item = $(this).closest(".plusminusunit").find("input");
item.val(Number(item.val()) - 1);
});

With images, the HTML would look like this (using your image URLs):
<span class="plusminusunit">
<img class="minus" src="http://lt.tonybet.com/assets/shared/mikro_tv-50ee396d59d5c38f979ad3fd93578f4f.png">
<input type="number" class="numbertype" value="10">
<img class="plus" src="http://lt.tonybet.com/assets/shared/mikro_tv-50ee396d59d5c38f979ad3fd93578f4f.png">
</span>

?I think it's possible to do with jQuery or maybe simple javascipt, but i don't know how..
I want do something like this :
when you push on + button, value will be bigger for 1 (0,12,3,4,5,6.... 10000)
when you push on - button, value will be smaller for 1 (10,9,8,7,6,5,4... 0)
