我现在想使用jquery easyui datagrid做一个分页,功能,打算通过url请求后台的servlet返回json数据,可是怎么弄servlet就是没反应,望大侠们帮一下忙,感激不尽!!
代码如下:
datagrid代码:
<script type="text/javascript">
$(function(){
$('#list_data').datagrid({
title:'日志列表',
iconCls:'icon-edit', //图标
width:700,
height:'auto',
nowrap:false,
striped:true,
border:true,
collapsible:false,
fit:true,
url:'listApp', //就是在这里没反应 listApp是我的servlet
remoteSort:false,
idField:'fldId',
singleSelect:true,
collapsible:true,
pagination:true,
rownumbers:true,
frozenColumns:[[
{field:'ck',checkbox:true}
]],
toolbar:[{
text:'添加',
iconCls:'icon-add',
handler:function(){
openDialog("add_dialog","add");
}
}, '-', {
text: '修改',
iconCls: 'icon-edit',
handler: function() {
openDialog("add_dialog","edit");
}
}, '-',{
text: '删除',
iconCls: 'icon-remove',
handler: function(){
delAppInfo();
}
}],
});
var p=$('#list_data').datagrid('getPager');
$(p).pagination({
pageSize:10,
pageList:[5,10,15],
beforePageText:'第',
afterPageText:'页 共{pages}页',
displayMsg:'当前显示 {from} - {to} 条记录 共{total} 条记录',
});
</script>
<body>
<center>
<table class="easyui-datagrid" id="list_data">
<thead>
<tr>
<th data-options="field:'id'">id</th>
<th data-options="field:'ip'">ip</th>
<th data-options="field:'picture1Name'">图片1</th>
<th data-options="field:'picture2Name'">图片2</th>
<th data-options="field:'picture1'">数据库图片1</th>
<th data-options="field:'picture2'">数据库图片2</th>
<th data-options="field:'simility'">相似度</th>
<th data-options="field:'time'">上传时间</th>
</tr>
</thead>
<tbody>......
下面是servlet代码:
@WebServlet("/listApp")
public class listApp extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("---------执行servlet－－－－－－－－－－－");
String page=request.getParameter("page");
String rows=request.getParameter("rows");
System.out.println(page);
System.out.println(rows);
int intPage = Integer.parseInt((page == null || page == "0") ? "1":page);
int number = Integer.parseInt((rows == null || rows == "0") ? "10":rows);
int start=(intPage-1)*number;
getuploadLogService service=new getuploadLogServiceImpl();
ArrayList logs=service.getpageData(start, number);
Map jsonMap=new HashMap();
jsonMap.put("total", service.getCount());
jsonMap.put("rows",logs);
response.setContentType("application/json");
JSONObject result=JSONObject.fromObject(jsonMap);
System.out.println(result.toString());
response.getWriter().write(result.toString());
}
