easyUi分页以及条件查询

//easyUi分页以及条件查询

JQuery 写法 (只需要找一个地方放入就行);

//大表格数据

var _getPage = localUrl + '/plugins/sqm/mservicemodel/findPage2EasyUI.ilf';
$('#dg').datagrid({
url : _getPage,
rownumbers : true,
pagination : true,
fitColumns : true,
fit : true,
singleSelect : false,
pageSize : 10,
pageList : [5, 10, 15],
remoteSort:true,
multiSort:true,
queryParams : {conditions : getSearchConditions()},
columns : [[
{field: 'id', title: "id", checkbox:true, hidden: false, width: 100, sortable: true, align: 'center'},
{field :'serviceCategory',title:'Service Category',hidden:false,width:50,sortable:true,align : 'center'},
{field :'serviceModel',title:'Service Model',hidden:false,width:50,sortable:true,align : 'center'},
{field :'description',title:'Description',hidden:false,width:50,sortable:true,align : 'center'}
]],
});

});

//加条件
function getSearchConditions() {
var searchName = $("#searchName").val().trim();

if(searchName!=null){
var param = [];
param.push({
"name" : "searchName",
"value" : searchName
});

var conditions = $.toJSON(param);

}

return conditions;
}

//查询表格数据
//searchGrid 绑定的是一个javascript事件方法
function searchGrid() {
var queryParams = {
conditions : getSearchConditions()
};
$('#dg').datagrid('load', queryParams);
}

//这是html标签页

<div data-options="region:'center',border:false" style="padding: 5px; width:900px; height: 300px;">
<table id="dg"></table>
</div>

<input style="height: 26px;" name="alarmName" class="easyui-validatebox validatebox-text" id="searchName">

<a href="javascript:searchGrid()" class="easyui-linkbutton" style="margin-bottom: -40px;" iconCls="icon-search">Query</a>

JAVA 代码(固定TestController.java

@RequestMapping(value = "/findPage2EasyUI.ilf")

// 处理条件
Map<String, String> c = null;
if (conditions != null && !"".equals(conditions)) {
c = DataTableCondition.getCondition(conditions);
}
// 查询并返回结果 dgpage 使用返回的数据，可以从这里书写条件
dgpage = testService.findPageByCondition(dgpage, c, orders);
