Jquery滚动到底部加载ajax

 

  1. 滚动到底部时,会附加 html 元素。这种附加机制只做了两次,最后附加了一个粉蓝色的按钮。
<!DOCTYPE html>
<html>
<head>
    <title>Demo: Lazy Loader</title>
    <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
    <style>
        #myScroll {
            border: 1px solid #999;
        }

        p {
            border: 1px solid #ccc;
            padding: 50px;
            text-align: center;
        }

        .loading {
            color: red;
        }
        .dynamic {
            background-color:#ccc;
            color:#000;
        }
    </style>
    <script>
        var counter=0;
        $(window).scroll(function () {
            if ($(window).scrollTop() == $(document).height() - $(window).height() && counter < 2) {
                appendData();
          //可以把加载ajax写在这里哦 } });
function appendData() { var html = ''; for (i = 0; i < 10; i++) { html += '<p class="dynamic">Dynamic Data : This is test data.<br />Next line.</p>'; } $('#myScroll').append(html); counter++; if(counter==2) $('#myScroll').append('<button id="uniqueButton" style="margin-left: 50%; background-color: powderblue;">Click</button><br /><br />'); } </script> </head> <body> <div id="myScroll"> <p> Contents will load here!!!.<br /> </p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> <p >This is test data.<br />Next line.</p> </div> </body> </html>
