Adding decimals to rangeslider

This is the function I'm using for making the range slider:
function rangeSlider(id, onDrag) {
var range = document.getElementById(id),
dragger = range.children[0],
draggerWidth = 20, // width of your dragger
down = false,
rangeWidth, rangeLeft;
dragger.style.width = draggerWidth + 'px';
dragger.style.left = -draggerWidth + 'px';
dragger.style.marginLeft = (draggerWidth / 2) + 'px';
range.addEventListener("mousedown", function(e) {
rangeWidth = this.offsetWidth;
rangeLeft = this.offsetLeft;
down = true;
updateDragger(e);
return false;
});
document.addEventListener("mousemove", function(e) {
updateDragger(e);
});
document.addEventListener("mouseup", function() {
down = false;
});
function updateDragger(e) {
if (down && e.pageX >= rangeLeft && e.pageX <= (rangeLeft + rangeWidth)) {
dragger.style.left = e.pageX - rangeLeft - draggerWidth + 'px';
if (typeof onDrag == "function") onDrag(Math.round(((e.pageX - rangeLeft) / rangeWidth) * 100));
}
}
}
// Run!
rangeSlider('range-slider-1', function(value) {
document.getElementById('test-result').innerHTML = value + '%';
});
rangeSlider('range-slider-2', function(value) {
document.getElementById('test-result').innerHTML = value + '%';
});

How can I have the output in decimals?
For example if I set the range from 10 - 100 I want it to be able to have the decimals. 10.01, 10.02, 10.03 ~ 99.97. 99.98, 99.99, etc.
What is the best way to achieve this?
Thanks guys, I'm loosing my mind over this for days.
Cheers.
Thanksl

Please try this may help to get 2 digit decimal point values:
if (typeof onDrag == "function") onDrag(parseFloat(((e.pageX - rangeLeft) / rangeWidth) * 100).toFixed(2));
Use it for like:
function updateDragger(e) {
if (down && e.pageX >= rangeLeft && e.pageX <= (rangeLeft + rangeWidth)) {
dragger.style.left = e.pageX - rangeLeft - draggerWidth + 'px';
var startpnt=10,endpnt=50,baseval_percent,baseval;
baseval_percent = ((e.pageX - rangeLeft) / rangeWidth) * 100;
baseval = (endpnt-startpnt)*baseval_percent/100;
baseval = baseval+startpnt;
if (typeof onDrag == "function") onDrag(parseFloat(baseval).toFixed(2));
}
}

JavaScript Css Animation

I have a Javascript animation at http://dev17.edreamz3.com/css/
All code works, however, there are performance problems. on Desktop, its good, On mobile things are so slow that it's unusable. I want to optimize the animation so that it runs smoothly on mobile. It can take 20 seconds or more for the animation to render.
Right now the way the code is designed is in js/anim.js there is a render() function that gets executed every time a scroll event happens. The problem is that this routine is not efficient, that's what I think of. Each time render() executes it loops through all the paths and sections of the maze and redraws them, is there any alternative way or a strategy to get it working both on mobile as well as desktop.
var offPathTime = 1000;
window.offSection = -1;
function render() {
// var top = ($window.scrollTop() + (0.4 * $window.height())) / window.scale;
var top = ($('.parent-div').scrollTop() + (0.4 * $('.parent-div').height())) / window.scale;
top -= 660;
top /= mazeSize.h;
if (window.offSection != -1) {
$body.addClass("blockScroll");
$('.parent-div').addClass("blockScroll");
// var wtop = $window.scrollTop() / window.scale;
var wtop = $('.parent-div').scrollTop() / window.scale;
wtop -= 660;
wtop /= mazeSize.h;
var $offSection = $("#offSection" + window.offSection);
var $section = $("#section" + window.offSection);
$(".section").removeClass("sectionActive");
$offSection.addClass("sectionActive");
$section.addClass("sectionActive");
var sTop = 200 -(mazeSize.h * (window.offSections[window.offSection].cy - wtop));
$container.animate({
left: 290 -(mazeSize.w * window.offSections[window.offSection].cx) + "px",
top: sTop + "px"
}, offPathTime);
// Path
var lr = offPaths[window.offSection].x1 > offPaths[window.offSection].x0;
var dx = Math.abs(offPaths[window.offSection].x1 - offPaths[window.offSection].x0);
var dashw = (dx * mazeSize.w) | 0;
$offPaths[window.offSection].css("width", "0px");
$offPaths[window.offSection].show();
if (lr) {
$offPaths[window.offSection].animate({
width: dashw + "px"
}, offPathTime);
} else {
var x0 = offPaths[window.offSection].x0 * mazeSize.w;
var x1 = offPaths[window.offSection].x1 * mazeSize.w;
$offPaths[window.offSection].css("left", x0 + "px");
$offPaths[window.offSection].animate({
width: dashw + "px",
left: x1 + "px"
}, offPathTime);
}
return;
}
$body.removeClass("blockScroll");
$('.parent-div').removeClass("blockScroll");
$(".offPath").hide();
if ($container.css("top") != "0px") {
$container.animate({
left: "-1550px",
top: "0px"
}, 500);
}
var pathIdx = -1;
var path0 = paths[0];
var path1;
var inPath = 0;
var i;
var curTop = 0;
var found = false;
for (i=0; i<paths.length; i++) {
var top0 = (i == 0) ? 0 : paths[i-1].y;
var top1 = paths[i].y;
if (top >= top0 && top < top1) {
pathIdx = i;
path1 = paths[i];
inPath = (top - top0) / (top1 - top0);
found = true;
if (i > 0) {
var dy = paths[i].y - paths[i-1].y;
var dx = paths[i].x - paths[i-1].x;
var vert = dx == 0;
if (vert)
$paths[i-1].css("height", (dy * mazeSize.h * inPath) + "px");
$paths[i-1].show();
}
} else if (top >= top0) {
path0 = paths[i];
var dy = paths[i].y - top0;
var vert = dy != 0;
if (i > 0) {
if (vert)
$paths[i-1].css("height", (dy * mazeSize.h) + "px");
$paths[i-1].show();
}
} else {
if (i > 0) {
$paths[i-1].hide();
}
}
curTop = top1;
}
// Check for an active section
$(".section").removeClass("sectionActive");
var section;
for (i=0; i<sections.length; i++) {
var d = Math.abs(sections[i].cy - (top - 0.05));
if (d < 0.07) {
var $section = $("#section" + i);
$section.addClass("sectionActive");
}
}
}

1) At the very least - assign all DOM objects to variables outside of the function scope. Like this:
var $parentDiv = $('.parent-div');
var $sections = $(".section");
...
function render() {
...
2) Also you should probably stop animation before executing it again, like this:
$container.stop(true).animate({
...
If you are running render() function on scroll - it will run many times per second. stop() helps to prevent it somewhat.
3) If it will not be sufficient - you can switch from jQuery to Zepto(jQuery-like api, but much faster and uses css transitions for animations) or to Velocity(basically drop-in replacement for jQuery $.animate and much faster than original) or even to GSAP - much more work obviously, but it is very fast and featured animation library.

Want the script corrected not to change the size of images

I want this script not to change the sizes of the images but the same sizes anywhere they are during sliding. The issue is somewhere in this code but i don't know which one that is changing the size. I want an even size

Stop function when pressing ctrl jQuery

So I am making a little game where you have to press Ctrl to stop a div from jumping randomly.
However I can't get it working...
The jumpRandom function works fine, until i put the randomJump(){return false;}; inside the if (event.ctrlKey) {}. What should I do to get it working?
js:
$(document).ready(function() {
function randomFromTo(from, to){
return Math.floor(Math.random() * (to - from + 1) + from);
}
$( "#goal" ).bind('mouseenter keypress', function(event) {
if (event.ctrlKey) {
randomJump(){return false;};
}
});
$('#goal').mouseenter(randomJump);
function randomJump(){
/* get Window position and size
* -- access method : cPos.top and cPos.left*/
var cPos = $('#pageWrap').offset();
var cHeight = $(window).height() - $('header').height() - $('footer').height();
var cWidth = $(window).width();
// get box padding (assume all padding have same value)
var pad = parseInt($('#goal').css('padding-top').replace('px', ''));
// get movable box size
var bHeight = $('#goal').height();
var bWidth = $('#goal').width();
// set maximum position
maxY = cPos.top + cHeight - bHeight - pad;
maxX = cPos.left + cWidth - bWidth - pad;
// set minimum position
minY = cPos.top + pad;
minX = cPos.left + pad;
// set new position
newY = randomFromTo(minY, maxY);
newX = randomFromTo(minX, maxX);
$('#goal').fadeOut(50, function(){
$('#goal').fadeIn(700);
});
$('#goal').animate({
left: newX,
top: newY,
duration: 500
});
}
});

Try this:
$("#goal").bind('mouseenter keypress', function (e) {
randomJump(e);
});
function randomJump(e) {
if (!e.ctrlKey) {
//do normal stuff
} else {
//depending on how permanent you need this to be...
//$("#goal").unbind('mouseenter keypress');
}
return !e.ctrlKey;
}

This javascript fails on mouseover

can anyone figure out why this JavaScript won't work? It correctly generates the document.write output, but when you try to drag it it starts complaining about top and left not being set. any idea whats wrong?

I've probably broken the script just TRYING to clean up this unholy mess and simplifying things a little, but at least it seems to be a bit more readable now (not including the array definitions):
<script type="text/javascript">
var dragging;
function mouseDown(el) {
dragging = el.id;
el.style.position = "fixed";
el.style.zIndex = 1000;
el.style.left = event.clientX - 75;
el.style.top = event.clientY-15;
}
function mouseOut(el) {
if (dragging === el.id) {
el.style.left = event.clientX - 75;
el.style.top = event.clientY - 15;
}
}
function mouseMove(el) {
if (dragging === el.id) {
el.style.left = event.clientX - 75;
el.style.top = event.clientY - 15;
}
}
function mouseUp(el, i) {
dragging = false;
if ( (event.clientX < 450) ||
(event.clientY > (180 + (abilitytypes[i] * 90)) ) ||
(event.clientY < (100 + (abilitytypes[i] - 1) * (90 * abilitytypes[i]) / ((4 % abilitytypes[i]) + 1)))) {
el.style.position = "relative";
el.style.top = 0;
el.style.left = 0;
el.style.zIndex = 0;
} else {
el.style.left = 460;
el.style.top = (Math.round((event.clientY - 30) / 45) * 45) + 15;
if ((abilitys[Math.round((event.clientY - 120) / 45)] != "") && (abilitys[Math.round((event.clientY - 120) / 45)] != el.id)) {
var subel = document.getElementById(abilitys[Math.round((event.clientY-120)/45)]);
subel.style.position="relative";
subel.style.left=0;
subel.style.top=0;
}
abilitys[Math.round((event.clientY - 120) / 45)] = el.id;
alert(abilitys);
}
}
for(var i = 0; i < 64; i++){
document.write("
<div onmousedown='mouseDown(this);'
onmouseout='mouseOut(this);'
onmousemove='mouseMove(el);'
onmouseup='mouseUp(this, i);'
id='"+i+"'
class='abilityblock"+abilitytypes[i]+"'>
<div class='abilityicon' style='background-position:"+(Math.floor(i/8)*-20)+"px "+((i%8)*-20)+"px;'></div>

</div>");
}
</script>
Phew. And after all that, I'm guessing your missing 'left' and 'top' parameters are because your dynamically computed element IDs are generating non-existent IDs in the mouseup handler.
My suggestion? Scrap this home-brew drag 'n drop stuff and use the functionality provided by Mootools or jQuery. Far less trouble, especially when having to deal with cross-browser differences.

Searching your code, you haven't defined an onmouseover event. You define onmousedown, onmouseout, onmousemove, and onmouseup. No onmouseover.
