今天写了一个mui下拉刷新的ajax实现

通过给后台传递last 和amount两个参数，获取json数组数据。

        <script>  
            mui.init({  
                swipeBack: false,  
                pullRefresh: {  
                    container: '#pullrefresh',  
                    down: {  
                        callback: pulldownRefresh  
                    }  
                }  
            });  
            /**  
             * 下拉刷新具体业务实现  
             */  
            var last=-5,amount=5;  
            function pulldownRefresh() {  
                    last =last+amount;  

                    var table = document.body.querySelector('.mui-table-view');  
                    var cells = document.body.querySelectorAll('.mui-table-view-cell');  
                    mui.ajax({  
                    type: "post",  
                    dataType: "json",  
                    url: "http://localhost/amazeui/data.php?action=item",  
                    data: "last="+last+"&amount="+amount,  
                    complete :function(){$("#load").hide();},  
                    success: function(msg){  
                        var data = msg;  
                        var tmp='';  

                        $.each(data, function(i, n){  

                                var li = document.createElement('li');  
                                li.className = 'mui-table-view-cell';  
                                li.innerHTML = '<a class="mui-navigate-right">' + n.itemname + '</a>';  
                        //下拉刷新，新纪录插到最前面；  
                        table.insertBefore(li, table.firstChild);  
                             });    

                        }  
                    });    

                    mui('#pullrefresh').pullRefresh().endPulldownToRefresh(); //refresh completed  

            }  

            if (mui.os.plus) {  
                mui.plusReady(function() {  
                    setTimeout(function() {  
                        mui('#pullrefresh').pullRefresh().pullupLoading();  
                    }, 1000);  

                });  
            } else {  
                mui.ready(function() {  
                    mui('#pullrefresh').pullRefresh().pullupLoading();  
                });  
            }  
        </script>
