下拉自动加载进行分页的运用越来越多，比起传统的分页该方法分页用户体验更好，布局也更简单了。目前正在使用和学习中……
JQuery插件：iScroll
页面布局：
下拉刷新...
翻页，是通过ajax请求，把页码传入一般处理程序，在一般处理程序中获得分页后的数据返回json数组对象。
下拉刷新：
/** * 下拉刷新 （自定义实现此方法） * myScroll.refresh(); // 数据加载完成后，调用界面更新方法 */ function pullDownAction() { setTimeout(function () { var el, li, i; el = document.getElementById('thelist'); //========================================== $.ajax({ type: "GET", url: "LoadMore.ashx", data: { page: generatedCount }, dataType: "json", success: function (data) { var json = data; $(json).each(function () { li = document.createElement('li'); // li.innerText = 'Generated row ' + (++generatedCount); li.innerHTML = '
'; el.insertBefore(li, el.childNodes[0]); }) } }); myScroll.refresh(); //数据加载完成后，调用界面更新方法 Remember to refresh when contents are loaded (ie: on ajax completion) }, 1000); // <-- Simulate network congestion, remove setTimeout from production! } 上拉刷新
function pullUpAction() { setTimeout(function () { var el, li, i; el = document.getElementById('thelist'); //========================================== $.ajax({ type: "GET", url: "LoadMore.ashx", data: { page: generatedCount }, dataType: "json", success: function (data) { var json = data; $(json).each(function () { li = document.createElement('li'); // li.innerText = 'Generated row ' + (++generatedCount); li.innerHTML = '; el.insertBefore(li, el.childNodes[0]); }) } }); //============================================ myScroll.refresh(); // 数据加载完成后，调用界面更新方法 Remember to refresh when contents are loaded (ie: on ajax completion) }, 1000); // <-- Simulate network congestion, remove setTimeout from production! } 初始化
