这就是一个非常简单的无刷新分页实现,使用了JQuery+ jquery.pagination框架。现在随着框架的流行,尤其是Jquery的流行,使用框架来开发是非常有效的。上面代码原理在代码中已有注释,也可参考Jquery的官方网站:。
现在就可以来开发我们的Ajax无刷新分页实现。基于上面的原理,在响应页码被按下的代码中pageselectCallback(),我们使用一个Ajax异步访问数据库,通过点击的页号将结果集取出后再用异步设置到页面,这样就可以完成了无刷新实现。
页码被按下的响应函数pageselectCallback()修改如下:
这样就可以用异步方式获取结果,用showResponse函数来处理结果了,showResponse函数如下:
function showResponse(request){ var content = request; var root = content.documentElement; var responseNodes = root.getElementsByTagName("root"); var itemList = new Array(); var pageList=new Array(); alert(responseNodes.length); if (responseNodes.length > 0) { var responseNode = responseNodes[0]; var itemNodes = responseNode.getElementsByTagName("data"); for (var i=0; i<itemNodes.length; i++) { var idNodes = itemNodes[i].getElementsByTagName("id"); var nameNodes = itemNodes[i].getElementsByTagName("name"); var sexNodes=itemNodes[i].getElementsByTagName("sex"); var ageNodes=itemNodes[i].getElementsByTagName("age"); if (idNodes.length > 0 && nameNodes.length > 0&&sexNodes.length > 0&& ageNodes.length > 0) { var id=idNodes[0].firstChild.nodeValue; var name = nameNodes[0].firstChild.nodeValue; var sex = sexNodes[0].firstChild.nodeValue; var age=ageNodes[0].firstChild.nodeValue; itemList.push(new Array(id,name, sex,age)); } } var pageNodes = responseNode.getElementsByTagName("pagination"); if (pageNodes.length>0) { var totalNodes = pageNodes[0].getElementsByTagName("total"); var startNodes = pageNodes[0].getElementsByTagName("start"); var endNodes=pageNodes[0].getElementsByTagName("end"); var currentNodes=pageNodes[0].getElementsByTagName("pageno"); if (totalNodes.length > 0 && startNodes.length > 0&&endNodes.length > 0) { var total=totalNodes[0].firstChild.nodeValue; var start = startNodes[0].firstChild.nodeValue; var end = endNodes[0].firstChild.nodeValue; var current=currentNodes[0].firstChild.nodeValue; pageList.push(new Array(total,start,end,current)); } } } showTable(itemList,pageList); }
如上代码就是用来处理通过Ajax异步请求Servlet后返回的XML格式的结果,其中Servlet代码在上篇中。其中itemList、pageList分别是解析返回后生成的用户List和分页导航,这样用户就可以以自己的展现方式展现数据了。
function pageselectCallback(page_index, jq){ var pars="pageNo="+(page_index+1); $.ajax({ type: "POST", url: " UserBasicSearchServlet", cache: false, data: pars, success: showResponse }); return false; }
