监听鼠标滚轮(js+jq),xp系统下也OK

应项目需求,运用了监听滚轮的事件,发现在xp系统下使用jquery的mousewheel.js来做,会导致无论滚轮怎么滚,都只能向下滚。。。后面使用了原生js的,就可以了。

jquery:

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <meta name="viewport" content="width=device-width, initial-scale=1.0">  <meta http-equiv="X-UA-Compatible" content="ie=edge">  <title>鼠标滚轮_jquery</title>  <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>  <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-mousewheel/3.1.13/jquery.mousewheel.min.js"></script>  <style>    #did {      width: 100px;      height: 100px;      background-color: #0ff;    }  </style></head><body>  <div id="did"></div>  <label for="detail">滚动方向:</label><input type="text" id="detail" /></body><script>  $(document).ready(function () {    $("#did").on(mousewheel, function (event, delta) {      var dir = delta > 0 ? 向上 : 向下;      $("#detail").val(dir)    });  });</script></html>

 

原生js(xp系统下用这个):

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <meta name="viewport" content="width=device-width, initial-scale=1.0">  <meta http-equiv="X-UA-Compatible" content="ie=edge">  <title>鼠标滚轮_原生js</title></head><style>  #did {    width: 100px;    height: 100px;    background-color: #0ff;  }</style><body>  <div id="did"></div>  <label for="wheelDelta">滚动方向:</label>(IE/Opera)<input type="text" id="wheelDelta" /><br>  <label for="detail">滚动方向:(Firefox)</label><input type="text" id="detail" /></body><script>  var scrollFunc = function (e) {    e = e || window.event;    var t1 = document.getElementById("wheelDelta");    var t2 = document.getElementById("detail");    if (e.wheelDelta) { //IE/Opera/Chrome       t1.value = e.wheelDelta < 0 ? 向下 : 向上;    } else if (e.detail) { //Firefox       t2.value = e.detail < 0 ? 向上 : 向下;    }  }  /*注册事件*/  if (document.getElementById("did").addEventListener) {    document.getElementById("did").addEventListener(DOMMouseScroll, scrollFunc, false);  } //W3C   document.getElementById("did").onmousewheel = scrollFunc; //IE/Opera/Chrome</script></html>
