Safari浏览器无法检测鼠标滚轮事件 [英] Can't detect mouse wheel event in safari

问题描述

我试图检测鼠标滚轮事件来调整滚动元素的大小。我有 #mainDiv 里面有几个 .foo 表。我想在滚动时更改 .foo 元素的缩放比例，但将 #mainDiv 的大小保持不变。这是我的功能：

  var content = document.getElementById（'mainDiv'）。getElementsByClassName（'foo'）; 
 var zX = 1; 
 $ b $（'＃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; 
} 
 zX + = dir; 
 for（var i = 0; i< content.length; i ++）{
 content [i] .style.transform ='scale（' + zX +'）'; 
} 
 return; 
}）; 
  

此功能在Chrome，Firefox和IE中运行正常，但不在safari中运行。问题是什么？

编辑： .foo 元素没有显示属性。这可能是一个问题吗？编辑2：我创建了jsfiddle来与代码一起玩。这是相当大的，但我们只需要JavaScript块的第一个功能。

https://jsfiddle.net/vaxobasilidze/cg3hkde7/9/

将一些项目拖到右侧，然后按添加新的链接。然后滚动。表格会改变它们的大小，但不会在Safari中。另外，如果您熟悉jsPlumb，也许您可​​以提供帮助，为什么终端不会更改它们的位置和大小。 解决方案

试试这段代码可能会帮助你

document.getElementById（myDIV）。 addEventListener（wheel，myfns）; function myfns（）{console.log（wheel）;}

 < div id =myDIV>滚动我！< / div>  

以下是jquery代码

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

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 #mainDiv's size the same. This is my function:

        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;
            }
            zX += dir;
            for (var i = 0; i<content.length; i++) {
                content[i].style.transform = 'scale(' + zX + ')';
            }
            return;
        });

This function works fine in Chrome, Firefox and IE, but not in safari. What's the problem?

EDIT: .foo elements don't have display property. Can that be a problem? I just don't want to set it because of the functionality of my app.

EDIT 2: I have created jsfiddle to play with code. It's pretty big but we need only first function in javascript block.

https://jsfiddle.net/vaxobasilidze/cg3hkde7/9/

Drag few items to the right side and press "Add new link". Then scroll. Tables will change their size, but not in Safari. Also, if you are familiar with jsPlumb, maybe you could help, why endpoints don't change their location and size.

解决方案

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++);
});
