Dynamically change content when slider values are updated

I am trying to dynamically change my page content when the slider values are changed. At the moment the user sets the slider, clicks a button below and content is displayed. When the sliders are changed again, the user has to click the button again to reload the content (because each button is assigned to the goalkeeperstat function.
<a class="chosenstat" title="Saves" value="saves" name="save" onclick="goalkeeperstat(this);">Saves</a>
Rather than having to press the button again I would like the content to change as soon as the user drags the slider handles to their chosen values.
Below is a screenshot of my page.

$(function initSlider() {
$("#slider1").slider({
range: true,
min: 0,
max: 100,
values: [0, 100],
slide: function update1 (event, ui) {
$(".amount").val(ui.values[0] + " - " + ui.values[1]);
slidervalueg1 = $('#g1').val(ui.values[0]);
slidervalueg2 = $('#g2').val(ui.values[1]);
}
});
$(".amount").val($("#slider1").slider("values", 0) +
" - " + $("#slider1").slider("values", 1));
});
function goalkeeperstat(element){
$('#result1').empty();
$('.amount').empty();
var category = element.getAttribute("value");
var categoryprompt = element.getAttribute("title");
var infocategory = element.getAttribute("name");
var position = 1;
var fr = $(myjson).filter(function (i,n){return n.element_type===position & n[category] >= slidervalueg1.val() && n[category] <= slidervalueg2.val() });
for (var i=0;i<fr.length;i++)
{
document.getElementById('result1').innerHTML += ("<div class='profile'><img src='https://platform-static-files.s3.amazonaws.com/premierleague/photos/players/110x140/p" + fr[i].code + ".png'/><div class='playerinfo'><p>Name: " + fr[i].first_name + " " + fr[i].second_name + "</p><p>Position: " + posdictionary[fr[i].element_type.toString()] + "</p><p class='teamname'>Team: " + dictionary[fr[i].team.toString()] + "</p><p>" + categoryprompt + ": <span class='categoryprompt'>" + fr[i][category] + "</span></p></div><div class='infobg'><p>Minutes: " + fr[i].minutes + "</p><p>Minutes per " + infocategory + ": " + parseFloat(Math.round((fr[i].minutes / fr[i][category]) * 100) / 100).toFixed(2) + "</p></div></div>");
}
}
EDIT: Tried using "stop" but it wouldn't work. Any other tips?

you can use event or method explicit :
$("#slider1").slider({
range: true,
min: 0,
max: 100,
values: [0, 100],
slide: function update1 (event, ui) {
$(".amount").val(ui.values[0] + " - " + ui.values[1]);
slidervalueg1 = $('#g1').val(ui.values[0]);
slidervalueg2 = $('#g2').val(ui.values[1]);
},
stop : function(event, ui){
console.log("slider changed");
// call your fucntion here
}
});

Counter Increment Exponentially

I'm trying to increment my counter every time but when the html is clicked the counter grows exponentially like +1, +2, +3, +4.
$('.dates').click(function(){
$('#output').html(function(i, val) { return val*1+1 });
});
HTML:
<div id="output">0</div>
Heart Animation Code:
var rand = Math.floor(Math.random() * 100 + 1);
var flows = ["flowOne", "flowTwo", "flowThree"];
var colors = ["colOne", "colTwo", "colThree", "colFour", "colFive", "colSix"];
var timing = (Math.random() * (1.3 - 0.3) + 1.6).toFixed(1);
// Animate Particle
$('<div class="particle part-' + rand + ' ' + colors[Math.floor(Math.random() * 6)] + '" style="font-size:' + Math.floor(Math.random() * (30 - 22) + 22) + 'px;"><i class="fa fa-heart-o"></i><i class="fa fa-heart"></i></div>').appendTo('.particle-box').css({ animation: "" + flows[Math.floor(Math.random() * 3)] + " " + timing + "s linear" });
$('.part-' + rand).show();
// Remove Particle
setTimeout(function () {
$('.part-' + rand).remove();
}, timing * 1000 - 100);
Why is it incrementing exponentially?
How do I make it increment by 1 every time? Like 0, 1, 2, 3, 4

Most likely, you are registering a new click event listener every time you click.
Please check and post the code that surrounds the line $('.dates').click(...).
Make sure this line is called only once in your code, and not again later.

May be it is considering it as string. Use parseInt to parse the value as an integer instead of using String Concatenation:
$('.dates').click(function() {
$('#output').html(function(i, val) {
return parseInt(val, 10) + 1;
});
});
Working snippet:
$('.dates').click(function() {
$('#output').html(function(i, val) {
return parseInt(val, 10) + 1;
});
return false;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Click
<div id="output">0</div>

Increase jquery variable by 1 on scroll

I'm having issues increasing a variable by 1 every time I scroll. I successfully increase the variable by 1, but only once. This is the code I got. I need to increase the variable page.
$(document).ready(function () {
$(document).scroll(function (e) {
currentPage = 0;
if ($(window).scrollTop() >= $(document).height() - $(window).height() - 10) {
++currentPage;
$.getJSON("../campus/Settings/TranslationSettings.ashx?command=show&page=" + currentPage + "&Lang=en", function (data) {
var items = [];
$.each(data.Keys, function (key, val) {
$("<ul/>", {
"class": "translateinfo",
html: "<li class='keystring'><span class='label'>text string:</span>" + val["text string"] + "</li>" + "<li class='autotranslate'><span class='label'>Automated translation:</span>" + val["automated translation"] + "</li>" + "<li class='functionnumber'><span class='label'>Function Number:</span>" + val["function number"] + "</li>" + "<li class='translateurl'><span class='label'>URL:</span>" + val["url"] + "</li>"
}).appendTo("#updatepanel");
});
});
}
});
});

Not sure if you copy/paste your entire code. But you're recreating currentPage everytime the user scroll
Working fiddle, I create the variable before the scroll loop.
var currentPage = 0;
$(document).scroll(function (e) {
if ($(window).scrollTop() >= $(document).height() - $(window).height() - 10) {
++currentPage;
console.log(currentPage);
}
})

How to combine two Javascript functions on the same object

I'm stuck trying to get random colour overlay on the pictures on this site.
http://www.reportageborsen.se/reportageborsen/wordpress
The Javascript I'm trying to combine are:
$(function() {
$('.media-box .mask').each(function() {
var hue = 'rgb(' + (Math.floor((256 - 199) * Math.random()) + 200) + ',' + (Math.floor((256 - 199) * Math.random()) + 200) + ',' + (Math.floor((256 - 199) * Math.random()) + 200) + ')';
$(this).css("background-color", hue);
});
});
///and///
$('.media-box').hover(function() {
$(this).find('.mask').stop(true, true).fadeIn();
}, function() {
$(this).find('.mask').stop(true, true).fadeOut();
});​
Is it possible to just get them together in some way?
Best Regards
Fortes

if you are looking to combine two functions in one, you may try this:
var getRandomInRange = function(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
};
$('.media-box').each(function() {
var mediaBox = $(this);
var mask = mediaBox.find('.mask');
var hue = 'rgb(' + getRandomInRange(200, 255) + ',' + getRandomInRange(200, 255) + ',' + getRandomInRange(200, 255) + ')';
mask.css("background-color", hue);
mediaBox.hover(function() {
mask.stop(true, true).fadeIn();
}, function() {
mask.stop(true, true).fadeOut();
});
});
Note, that I also moved random number generator to separate function, just for clarity. Let me know if this worked.

Button image change on a timer

In my project I have a page which contains 5 image buttons laying horizantally.
When the page loads image on the Button1 should change(remaining 4 buttons remains same).
After 3 seconds Button1 comes back to its original image and image on Button2 will change.
After 3 seconds Button2 comes back to its original image and image on Button3 will change.
And so on..
But After the Button5 is done , It should come back to the Button1 image again.
This should go on in a continuous loop.
Here is my code.But its not working I don't know the reason why its not working.
any help will be appreciated.
Here is my code
$(document).ready(function (){
BeginRotation();
});
function BeginRotation() {
rotateButton(0);
}
function rotateButton(buttonIndex) {
var previousIndex = (buttonIndex + 4) % 5;
var previousCurrentClass = 'main-nav-button' + (previousIndex + 1) + '-on';
var previousNewClass = 'main-nav-button' + (previousIndex + 1);
var currentClass = 'main-nav-button' + (buttonIndex + 1);
var newClass = 'main-nav-button' + (buttonIndex + 1) + '-on';
// alert('Previous Current Class: ' + previousCurrentClass + '\nPrevious New Class: ' + previousNewClass + '\nCurrent Class: ' + currentClass + '\nNew Class: ' + newClass);
$('.' + currentClass).removeClass(currentClass).addClass(newClass);
$('.' + previousCurrentClass).removeClass(previousCurrentClass).addClass(previousNewClass);
window.setTimeout(rotateButton((buttonIndex + 1) % 5), 3000);
}

One thing that is incorrect for sure
window.setTimeout(rotateButton((buttonIndex + 1) % 5), 3000);
It should be
window.setTimeout("rotateButton(" + ((buttonIndex + 1) % 5) + ")", 3000);

I didn't test this code, but something like this should work:
jQuery(function($){
var $btns = $('a.btn');
var index = 0;
setInterval(function() {
$btns.removeClass('rotateThis');
$btns[index].addClass('rotateThis');
index = (index + 1 >= $btns.size()) ? 0 : index + 1;
}, 3000);
});
$('a.btn') being whatever selector works to grab your image buttons of course.
