I have a wrapper called #mousearea and I have a div called #mouseshift what I would like to do is when I hover over #mousearea I would like to shift the translate3d(0,230%,0) value between a particular range.

I have got the mousemove working but I currently end up with something like translate3d(7881%,230%,0) it's just too sensetive I would like it to translate the X co-ordinate between something like 0-60% so it's far more subtle.

Here is what I have so far:

jQuery(document).ready(function($){
    $('#mousearea').mousemove(function (e) {

        var shiftAmount = 1;

        $('#mouseshift').css(
            'transform', 'rotate(90deg) translate3d(' + -e.pageY + shiftAmount + '%,230%,0)'
        );
    });
});

Update:

This is a little closer, except it logs the correct translate3d but doesn't apply it to #mouseshift.

$('#mousearea').mousemove(function(e){
        var x = e.pageY - this.offsetTop;
        var transfromPosition = 'translate3d(' + x + ', 230%, 0)';
        console.log(transfromPosition);

        if ((x <= 800)) {
            //$('#mouseshift').css({'top': x});
            $('#mouseshift').css('transform', transfromPosition);
        }
    });

Final Solution:

jQuery(document).ready(function($){

    $('#mousearea').mousemove(function(e){

        var min = 50;
        var max = 70;

        var x = e.pageY;
        var windowHeight = window.innerHeight;

        scrolled = (x / windowHeight);
        percentageScrolled = scrolled * 100;

        offsetScroll = max - min;
        offsetPercentage = scrolled * 20;
        translateX = min + offsetPercentage;


        console.log(x + 'px');
        console.log(windowHeight + 'px window height');
        console.log(percentageScrolled + '% scrolled');
        console.log(offsetScroll + 'offset scroll');
        console.log(offsetPercentage + '% offset percentage');




        var transfromPosition = 'rotate(90deg) translate3d(' + translateX + '%, 230%, 0)';
        $('#mouseshift h1').css('transform', transfromPosition);
    });

});

Convert to a reusable plugin I would like to extend this to work with more than one object now and each object would have a different max and min value:

This is what I have but it seems to effect all the items on only use on elements max and min.

$(function () {
    $('#mouseshift-1, #mouseshift-2').mouseShift();
});    
(function ($) {
    $.fn.mouseShift = function () {
        return this.each(function () {
            var myEl = $(this);
            var min = $(this).data('min');
            var max = $(this).data('max');

            $('#mousearea').mousemove(function (e) {
                var yPosition = e.pageY;
                var windowHeight = window.innerHeight;

                scrolled = (yPosition / windowHeight);
                //percentageScrolled = scrolled * 100;
                offsetRange = max - min;
                offsetRangePercentage = scrolled * 20;
                offset = min + offsetRangePercentage;

                ////  Debug
                console.log('max: ' + max + ', Min:' + min);
                console.log(yPosition + 'px');
                console.log(windowHeight + 'px window height');
                //console.log(percentageScrolled + '% scrolled');
                console.log(offsetRange + 'px offset scroll');
                console.log(offsetRangePercentage + '% offset percentage');

                var transfromPosition = 'rotate(90deg) translate3d(' + offset + '%, 230%, 0)';
                myEl.css('transform', transfromPosition);
            });
        });
    };
})(jQuery);

And some HTML for clarity:

<div class="column"><h1 id="mouseshift-1" data-min="50" data-max="70">boo</h1></div>
      <div class="column"><h1 id="mouseshift-2" data-min="20" data-max="90">bah</h1></div>
      <div class="column"><h1 id="mouseshift-3" data-min="80" data-max="100">bing</h1></div>

• I don't know what your maximum mouseposition is, but you could simply do x / window.innerWidth * 60 to get a number between 0 and 60. The only thing I don't know is what width it should be, so window.innerWidth might need to be replaced by something else... – somethinghere Commented Mar 7, 2016 at 13:27

I think what you are looking for is finding an average that your can distribute. The best way to do this is to divide by the maximum amount it can move, and multiply it by the maximum value it can have, so basically:

position / maxposition * maxvalue

The first bit will return a number between 0 and 1, while the last bit will make it the value between 0 and 60. Below I have built a simply (jquery-less) version of it to show how this would work:

var mousePointer = document.getElementById('test')

document.addEventListener('mousemove', function(e){
  var x = e.pageX / window.innerHeight;
      x = x * -60;
  mousePointer.style.webkitTransform = 'translateX(' + x + '%)';
  mousePointer.style.transform = 'translateX(' + x + '%)';
})

#test {
  position: absolute;
  left: 50%;
  top: 50%;
  width: 20px;
  height: 20px;
  background: red;
}

<div id="test"></div>

Update: Reusable Snippet

I don't really like using jQuery, so once again it will be vanilla javascript (but it's pretty simple). Is that what you were - sort of - trying to do with the reusable plugin?

var divs = Array.prototype.slice.call(document.querySelectorAll('[data-range]'));

document.addEventListener('mousemove', function(e){
  
  var eased = e.pageX / window.innerWidth;
  
  divs.forEach(function(div){
    
    var range = div.getAttribute('data-range').split(',');
    var min = parseFloat(range[0]);
    var max = parseFloat(range[1]);
    
    var ease = min + (eased * (max - min));
    
    div.style.webkitTransform = 'translateX(' + ease + '%)';
    div.style.transform = 'translateX(' + ease + '%)';
    
  });
  
});

div {
  position: absolute;
  left: 50%;
  top: 50%;
  width: 200px;
  height: 200px;
  background: gray;
}

#d2 { background: yellow; }
#d3 { background: #666; }

<div data-range="60,70" id="d1"></div>
<div data-range="-70,70" id="d2"></div>
<div data-range="-60,-70" id="d3"></div>

From simple reading, I see that you're missing a % sign. Should be like this:

$('#mousearea').mousemove(function(e){
    var x = e.pageY - this.offsetTop;
    var transfromPosition = 'translate3d(' + x + '%, 230%, 0)';
    console.log(transfromPosition);

    if ((x <= 800)) {
        //$('#mouseshift').css({'top': x});
        $('#mouseshift').css('transform', transfromPosition);
    }
});

This should be working like your first example, where you do use % for both values inside the translate3d string.

Update:

To coerce your x Value to something between 0 and 60, you need to find a pair of possible min and max values for x. Then you can do something like what's shown in this answer:

Convert a number range to another range, maintaining ratio
