datagrid参数queryParams--easyUI

Html

         <div  region="center" border="false"  style="padding:0px 3px 0px 3px;margin:0px;">

<table id="test"></table>

</div>

初置化gird

$(function(){

loadgrid();

//loadcombobox(null);

});

function loadgrid(){

$('#test').datagrid({

title:'任免信息列表',

fit:true,

nowrap: false,

striped:false,

//url:'rm.json',

url:'http://127.0.0.1:8080/web/AppAndRemoveServer.server',

queryParams:{},

sortName: 'appandremove_id',

sortOrder: 'asc',

remoteSort: false,

idField:'appandremove_id',

frozenColumns:[[

{field:'ck',checkbox:true}

]],

columns:[[{field:'appandremove_id',title:'任免批次编号',width:200,sortable:true},

{field:'batch_name',title:'任免批次名称',width:240,sortable:true},

{field:'batch_no',title:'任免批次编号',width:100,sortable:true},

{field:'recorder_date',title:'登记时间',width:120,sortable:true},

{field:'recorder_id',title:'登记人',width:100,sortable:true},

{field:'state',title:'状态',width:100,sortable:true},

{field:'memo',title:'备注',width:300}

]],

pagination:true,

pageNumber:1,

pageSize:5,

pageList:[5,10],

//singleSelect:true,

rownumbers:true

});

}

服务端接收rows、page、order、sort参数

参数名称是easyui起的，值也是自动绑定

可以在服务端通过request.getParameterNames();查看有什么参数

接收参数值

if(null!=request.getParameter("rows")) {             pageRows=Integer.parseInt(request.getParameter("rows").toString());

}

if(null!=request.getParameter("page")) {

page=Integer.parseInt(request.getParameter("page").toString());

}

if(null!=request.getParameter("order")) {

order=request.getParameter("order").toString();

}

if(null!=request.getParameter("sort")) {

order=request.getParameter("sort").toString();

}

然后拼装sql语句实现分页。

增加查询参数，重新加载表格

function reloadgrid (stateVal)  {

//查询参数直接添加在url中

/* var url =$('#test').datagrid('options').url;

url = "http://127.0.0.1:8080/web/AppAndRemoveServer.server?state=" +stateVal;

//重新赋值url 属性

$('#test').datagrid('options').url=url;

$("#test").datagrid('reload');

*/

//查询参数直接添加在queryParams中

var queryParams = $('#test').datagrid('options').queryParams;

queryParams.state = stateVal;

$('#test').datagrid('options').queryParams=queryParams;

$("#test").datagrid('reload');

}
