【问题描述】：

我正在使用 scrollTo jQuery 插件来自动滚动到页面的特定部分。单击页面上的按钮（#neo_scroll_button）时，我希望页面滚动div#neo_home_panel的长度。

这是我的 JSFiddle：http://jsfiddle.net/h9kw9/

这是我的 HTML

<body>
<div id="neo_wrapper">
    <div id="neo_home_panel">   <!-- Start panel 1 -->
        <div id="neo_scroll_button">
            <p>Enter</p>
        </div></a>
    </div>  <!-- End of panel 1 -->
    <div id="neo_content_panel">    <!-- Start panel 2 -->
        <div class="neo_img_container">
            <img src="http://fpoimagery.com/?t=px&w=450&h=250&bg=0ff&fg=000000" />
        </div>
        <div class="neo_text_container">

SASS：

 body, html { 
width: 100%;
height: 100%;
padding: 0;
margin: 0;
}

#neo_wrapper {  /* Wrapper for entire page */
width: 100%;
height: 1045px;
margin: 0 auto;

#neo_home_panel {   /* Opening panel */
    width: auto;
    height: auto;
    margin: 0 auto;
    background: #999999; 
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    -ms-background-size: cover;
    background-size: cover;
    /*overflow: hidden;*/

    #neo_scroll_button {    /* Div that enables scroll */
        position: absolute;
        bottom: 25px;
        left: 0;
        right: 0;
        margin: 0 auto;
        width: 150px;
        height: 35px;
        background: #F00;
        color: #FFF;
        text-align: center;
        line-height: 35px;
        display: table; /* Allows text to be completely centered */
        cursor: pointer;

        a { /* Formatting for link */
            &:link {text-decoration: none; color: #FFF;}
            &:visited {text-decoration: none; color: #FFF;}
        }
    }
}

#neo_content_panel {    /* Content panel (images/text) */
    width: 960px;
    height: 100%;
    margin: 0 auto;
    background: #CCC;
    /*overflow: hidden;*/

    .neo_img_container {    /* Container for images */
        float: left;
        width: 450px;
        height: 250px;
        /*margin-right: 25px;*/
        &:nth-child(odd){
            margin: 0 60px 15px 0; 
        }
    }

    .neo_text_container {   /* Container for text */
        float: left;
        width: 450px;
        height: 250px;
        margin: 0 auto;
        &:nth-child(odd){
            margin: 0 60px 15px 0; 
        }
    }

    .neo_img_container2 {
        width: 100%;
        height: 250px;
        margin: 0 auto;
    }
}
}

还有 jQuery

$(document).ready(function() {

var $homePanelHeight = parseInt($('#neo_home_panel').height());

$('#neo_scroll_button').click(function() {
    $.scrollTo('$homePanelHeight', 800);
    //alert("Hello world");
});

 });

【问题讨论】：

太棒了，看来我的想法是对的。出于某种原因，查看 API 我认为变量需要用引号引起来。还在学习！

不知何故，我得到的回答我问题的评论被删除了，我应该如何将此问题标记为已回答？

标签： javascript jquery html sass scrollto

【解决方案1】：

借助锚标签我们可以轻松实现FIDDLE DEMO。

这是我在neo_scroll_button中添加的内容

 <a href="#end"> <div id="neo_scroll_button"><p>Enter</p> </a>

最后是neo_content_panel：

 <dev id="end"></div>

另外，在 JS 中：

$(function() {
  $('a').bind('click', function(event) {
    var $anchor = $(this);
    $('html, body').stop().animate({
      scrollTop: $($anchor.attr('href')).offset().top
    }, 1000);
    event.preventDefault();
  });
});
