Jquery点击加载更多

一、点击加载更多有点像分页获取数据类似，下面是本人写的一个简单的小例子

<body>
    <div id="list-new">

    </div>
    <!--加载更多按钮-->
    <div class="js-load-more">加载更多</div>

$(function(){

    /*初始化*/
    var counter = 0; /*计数器*/
    var pageStart = 1; /*offset*/
    var pageSize = 4; /*size*/



    /*首次加载*/
    getData(pageStart, pageSize);

    /*监听加载更多*/
    $(document).on('click', '.js-load-more', function () {
        pageStart++
        getData(pageStart, pageSize);
    });
    function getData(offset,size){
        $.ajax({
            type: 'GET',
            url: '/PhoneManage/Notice/listJson?pageSize=' + size + '&pageIndex=' + offset, //这里offset,size无作用，仅方便调试
            dataType: 'json',
            success: function(reponse){
                var data = reponse;
                var sum = reponse.length;
                var result = '';
                /************业务逻辑块：实现拼接html内容并append到页面*****************/
                //console.log(offset , size, sum);

                for (var i = (offset -1) * size; i < sum; i++) {                
                    result += '<a href="/PhoneManage/Notice/text?id=' + data[i].F_Id + '"><div class="list"><div class="text"><h3>' + data[i].F_Title + '</h3><p>'
                            + data[i].F_CreatorTime + '</p></div><div class="back"><img src="/Content/Phone/images/back1.png" width="32" /></div></div></a>';
                }
                $('#list-new').append(result);
                /*******************************************/
                /*隐藏more*/
                if ((offset * size) > sum) {                
                    $(".js-load-more").hide();
                }else{
                    $(".js-load-more").show();
                }
            },
            error: function(xhr, type){
                alert('Ajax error!');
            }
        });
    }
});
</script>
</body>
