Question

我有html页面，其中三列调整到窗口的高度。每列都有自己的内容，可以滚动。因为整个页面的高度与窗口的高度相同，所以窗口的滚动事件不会触发。但是我也失去了每一列的滚动事件，他们也没有触发事件。

这个页面在jsFiddle（here you can check my source code）中完美运行的有趣事实。我认为这是因为这项服务的框架性质。问题是如何在浏览器中捕获这些滚动事件？感谢。

CSS：

html, body, div {
    margin: 0;
    border: 0 none;
    padding: 0;
}

html, body, #outerDiv, #left-container, #center-container, #right-container {
   height: 100%;
   min-height: 100%;
}

body {
    font-family: Georgia, serif;
}

#outerDiv {
    width: auto;
    margin: 0 auto;
    overflow: hidden;
}

#leftDiv {
    float: left;
    position: relative;
    width: 32.7%;
    height:100%;
}

#left-container {
    overflow: scroll;
    position: relative;
}

#left {
    display: inline-block;
    position: absolute;
    top: 0px;
}

#centerDiv {
    float: left;
    position: relative;
    width: 34.6%;
    height:100%;
}

#center-container {
    overflow: scroll;
    position: relative;
}

#center {
    display: inline-block;
    position: absolute;
    top: 0px;
}

#rightDiv {
    float: left;
    position: relative;
    width: 32.7%;
    height:100%;
}

#right-container {
    overflow: scroll;
    position: relative;
}

#right {
    display: inline-block;
    position: absolute;
    top: 0px;
}

.green_highlight {
    background-color: green;
}

img {
    position: absolute;
    width: 20px;
    height: 20px;
    z-index: 1;
    top: 0px;
    right: 15px;
}

img:hover {
    cursor: pointer
}

JavaScript的：

$(window).scroll(function() {
  alert("Scroll event from window");
});

$('#centerDiv').scroll(function() {
  alert("Scroll event from centerDiv");
});

$('#center-container').scroll(function() {
  alert("Scroll event from center-container");
});

$('#center').scroll(function() {
  alert("Scroll event from center");
});

Answer 1

这些都应该与jQuery一起使用。

听起来好像你可能不理解为什么它在jsFiddle中有效，这是因为它会自动包含jQuery。

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script>

将其放入<head>

Answer 2

问题是因为事件处理程序在未初始化的文档上初始化。我只是将事件处理程序放在$（document）.ready（function（）{}）中;解决这个问题。

JavaScript，丢失滚动事件
