This article mainly introduces the function of using js to scroll the scroll bar to the bottom of the page to click to load more. Compared with most websites, isscroll.js is used to realize the pull-up to load more or the pull-down to refresh function. Easier for everyone to understand. The simple idea here is that all the data on the page, according to the display requirements, which parts are displayed, then the rest is hidden. If there is still data, just click to load more and continue to display the data; until no more data is displayed, loading complete will appear.

When loading, you can set it to display "Loading..." If more data is not displayed, you can add a "Click to load more" button at the bottom. Until there is no more data, it will be displayed that all loading is completed.

js scrolling click to load more data The specific sample code is as follows：

<div class="loading">
    <div class="hidden"></div>
    <ul class="img-list"><li class="pic_list_3"><div class="pic_list_li"><div class="img"><a href="www.php.cn"><img  src="img/1.png" alt="" width="100" height="100"></a>

                $(this).attr(&#39;src&#39;, $(this).attr(&#39;realSrc&#39;));
            })
            for (var i = loading._default; i < lis.length; i++) {
                _content.push(lis.eq(i));

                    $(&#39;.loading .btn-more&#39;).html("<p>全部加载完毕</p>");
                    break;
                }
                $(".loading ul.img-list").append(target);
                $(".loading ul.img-list img").eq(mLis + i).each(function() {
                    $(this).attr(&#39;src&#39;, $(this).attr(&#39;realSrc&#39;));
