Can't Detect Mouse Wheel Event In Safari

I'm trying to detect mouse wheel event to resize elements on scroll. I have #mainDiv with several .foo tables inside. I want to change .foo element's scale on scroll, but leave #ma

Solution 1:

Try this code might help you

document.getElementById("myDIV").addEventListener("wheel", myfns);

function myfns(){

  console.log("wheel");

}

<div id="myDIV">scroll on me!</div>

Following is jquery code

var count = 0;
$( "#target" ).scroll(function() {
  console.log("wheel " + count++);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

<div id="target" style="overflow: scroll; width: 200px; height: 100px;">

I have edited your code now mouse scroll work for me try it hope it will works

var setZoom = function(z, el, instance) {
  instance = instance || jsPlumb;
  var p = ["-webkit-", "-moz-", "-ms-", "-o-", ""],
    s = "scale(" + z + ")";
  for (var i = 0; i < p.length; i++) {
    //el.css(p[i] + "transform", s);          //FIRST WAY TO TRANSFORM
    el.style.transform = 'scale(' + zX + ')'; //SECOND WAY TO TRANSFORM
  }
  instance.setZoom(z);
};

var content = document.getElementById('mainDiv').getElementsByClassName('foo');
var zX = 1;
$('#mainDiv').bind('mousewheel DOMMouseScroll', function(e) {
  e.preventDefault();
  var dir;
  if (e.originalEvent.wheelDelta > 0 || e.originalEvent.detail < 0) {
    dir = 0.05;
  } else {
    dir = -0.05;
  }
  if ((zX + dir) >= 0.05) {
    zX += dir;
  }
  for (var i = 0; i < content.length; i++) {
    content[i].style.transform = 'scale(' + zX + ')';
    setZoom(zX, content[i]);
  }
  return;
});






var count = 0;
$("#leftDiv").scroll(function() {
  console.log("wheel " + count++);
});
