javascript - 修复元素滚动到 Div

Question

我想要一个元素，在本例中称为 neo_about_nav，在滚动到称为 #neo_about_section 的 div 时保持固定在其位置。

这是我的 SASS

/* Container for "About" section */
    #neo_about_section {
        width: 960px;
        height: 250px;
        background: #FFF;
        margin: 0 auto;

        /* Container for centered text */
        .neo_text_container {   
            width: 480px;
            text-align: center;  
            color: #000;
            float: left;
            margin: 25px 90px 0 240px;

            /* About section "Read More" button */
            #neo_about_button { 
                width: 150px;
                height: 25px;
                background-color: #F90;
                color: #FFF;
                text-align: center;
                line-height: 25px;
                margin: 0 auto;
                margin-top: 15px;
                cursor: pointer;
                display: table; /* Fix to make text center aligned */
            }   /* About button end */
        }   /* Text container end */

        /* About section navigation that scrolls to sections on home page */
        .neo_about_nav {
            position: absolute;
            width: 150px;
            height: 200px;
            background: #CCC;
            color: #000;
            float: left;
            margin: 25px 0 0 820px;
            z-index: 500;

            /* Styling for navigation list */
            ul {list-style: none; padding-left: none; font-size: 14px;}
            li {
                background: #FFF;
                margin: 10px 0 0 -40px;
                cursor: pointer; 
                a {
                    /* Formatting for list items */
                    &:link {text-decoration: none; color: #FFFFFF;}
                    &:hover {color: #CCC;}
                    &:active {color: #222;}
                    &:visited {text-decoration:none; color: #FFF;}
                }
            }
        }   /* About section nav end */
    }   /* About section end */

这是HTML

Answer 1

第一步

放在你的 jquery 文件或标题部分

$(window).scroll(function(){
    var p = $( ".your-div" ).height();

    if ($(this).scrollTop() > p) {
        $('.fixeddiv').addClass('fixed');
    } else {
        $('.fixeddiv').removeClass('fixed');
    }
});

第 2 步放上你的css文件

.fixed{ position:fixed; top:0; z-index:1000; width:100%; background:#FFF; }
