我在java中实现jqgrid。
在实施search functionality时我无法获得搜索结果，它重新加载所有记录的网格数据，而不是过滤结果。请帮助我解决此问题并指导我实现搜索功能以及advanced search function in java.
我已经完成的部分代码：
var lastselected, lastsel2;
var curRowId = -1;
var gridContainerId = "#data-grid-container";
var la;
var usernames;
$(document).ready(
function() {
$(gridContainerId).jqGrid(
{
url : 'ManageUserServlet?methodName=fetchAllUsers',
datatype : "json",
colNames: ['Email', 'Lastname', 'Firstname', 'Group', 'Active'],
/*colModel: [
{ name: 'Email', width: 100, index: 'Email', searchoptions: { sopt: ['eq', 'ne']} },
{ name: 'Lastname', index: 'LastName', searchoptions: { sopt: ['eq', 'ne', 'cn']} },
{ name: 'Firstname', index: 'FirstName', searchoptions: { sopt: ['eq', 'ne', 'cn']} },
{ name: 'Group', index: 'Group', searchoptions: { sopt: ['eq', 'ne', 'cn']} },
{ name: 'Active', index: 'Active', searchoptions: { sopt: ['eq', 'ne', 'cn']} }

非常感谢在 jqgrid 中实现搜索的指导。
更新：
这是在 servlet 上创建JSON object填充网格数据的代码：
private void fetchAllUsers() {
List<UserVO> lstUsers = adminServices.fetchAllUsers();
if(lstUsers != null && !lstUsers.isEmpty()) {
try{
JSONObject responseData=new JSONObject();
responseData.put("total",2);
responseData.put("page",1);
responseData.put("records",3);
JSONArray cellArray=new JSONArray();
JSONArray cell = new JSONArray();
JSONObject cellObj=new JSONObject();
int i=1;
for(UserVO userVO : lstUsers) {
if(userVO!= null) {
cellObj.put("id",i);
cell.add(userVO.getEmail());
cell.add(userVO.getLastName());
cell.add(userVO.getFirstName());
cell.add(userVO.getGroupVO().getGroupName());
if(userVO.isActive()){
cell.add("Active");
}else{
cell.add("In-Active");
}
cellObj.put("cell", cell);
cell.clear();
cellArray.add(cellObj);
i++;
}
}
responseData.put("rows", cellArray);
//response.setContentType("applisation/json");
out.print(responseData);
out.flush();
}catch(Exception e) {
System.out.println("There is some error");
}
}
