datatable中如果不想对前几列进行排序，使用以下代码：
$('#informationList').DataTable({
//对0,1,2列不排序
"columnDefs": [ {
"orderable": false,
"targets": [0,1,2]
}],
//如果需要重载页面则需要销毁页面，以便于重新加载
destroy:true,
//自带的搜索框，如果不需要则可以设置false，默认为true
searching:true,
//表格分页
paging: true,
//汉化
language: {
"sProcessing": "处理中...",
"sLengthMenu": "显示 _MENU_ 项结果",
"sZeroRecords": "没有匹配结果",
"sInfo": "显示第 _START_ 至 _END_ 项结果，共 _TOTAL_ 项",
"sInfoEmpty": "显示第 0 至 0 项结果，共 0 项",
"sInfoFiltered": "(由 _MAX_ 项结果过滤)",
"sInfoPostFix": "",
"sSearch": "简单搜索:",
"sUrl": "",
"sEmptyTable": "表中数据为空",
"sLoadingRecords": "载入中...",
"sInfoThousands": ",",
"oPaginate": {
"sFirst": "首页",
"sPrevious": "上页",
"sNext": "下页",
"sLast": "末页"
},
"oAria": {
"sSortAscending": ": 以升序排列此列",
"sSortDescending": ": 以降序排列此列"
}
}
}); -
现出现需求：datatable自带的搜索框满足不了需求，需要自己动手写搜索语句，并且把数据都已经获取到list集合中了，如何操作？

查看官方文档，datatable的数据源就三种，其中最方便的一组是使用了array集合来存储数据，如下：
/**
* 条件查询
*
* @param title
* @param level
* @param industry
* @param company
* @param keyword
* @param function
* @return
*/
@RequestMapping("/search")
@ResponseBody
public Map<String, Object> searchCaseByCondition(@RequestParam("name") String name, @RequestParam("title") String title, @RequestParam("level") String level, @RequestParam("industry") String industry, @RequestParam("company") String company, @RequestParam("keyword") String keyword, @RequestParam("function") String function, String state) {
System.out.println(state);
System.out.println(name);
System.out.println("1111");
Map<String, Object> returnMap = new HashMap<>();
if ("".equals(name)) {
name = null;
}
if ("".equals(level)) {
level = null;
}
if ("".equals(title)) {
title = null;
}
if ("".equals(industry)) {
industry = null;
}
if ("".equals(company)) {
company = null;
}
if ("".equals(keyword)) {
keyword = null;
}
if ("".equals(function)) {
function = null;
}
if (name == null && function == null && keyword == null && company == null && industry == null && title == null && level == null) {
String error = "输入参数错误，请重新输入！";
return (Map<String, Object>) returnMap.put("error", error);
}
List<Problem> results = caseService.searchByConditions(name, title, level, industry, company, keyword, function, state);
returnMap.put("searchResults", results);
return returnMap;
}

前台接收后的代码：
$("#btn_search").on('click', function () {
//点击后，需要想后台传输数据
//0,申请人
var pname=$("#proName option:selected").val();
if (pname==null){
pname=null;
}
//1,传送难度级别
var pLevel = $("#proLevel option:selected").val();
if (pLevel == null) {
pLevel = null;
}
// 2,传输所属行业
var pIndustry = $("#proIndustry option:selected").val();
if (pIndustry == null) {
pIndustry = null;
}
//3,传输来源企业
var pCompany = $("#proCompany option:selected").val();
if (pCompany == null) {
pCompany = null;
}
//4,传输关键字,
var keyword = $("#proKeyword option:selected").val();
if (keyword == null) {
keyword = null;
}
//5,传输实现功能
var pFunction = $("#proFunction option:selected").val();
if (pFunction == null) {
pFunction = null;
}
//6,传输难题名称
var pTitle = $("#proTitle option:selected").val();
//7，传值，证明是通过的
var pState='1';
console.log(pState);
$.ajax({
type: "post",
url: "/case/search",
dataType: "json",
data:
{
name: pname,
title: pTitle,
level: pLevel,
industry: pIndustry,
company: pCompany,
keyword: keyword,
function: pFunction,
state:pState
},
error: function () {
},
success: function (data) {
//搜索到数据后去掉模态框
$("#passSearchModal").modal('hide');
console.log(data);
$('#declarationList').DataTable({
destroy: true,
data: data.searchResults,
columns: [
{data: 'proId',render:function (data,type,row,meta) {
return '<label class="checkbox-inline"><input type="checkbox" class="myid2" name="items" id="items" value="'+row.proId+'">'+row.proId+'</label>'
}},
{data: 'proTitle',render:function (data, type, row, meta) {
return '<span><a href="/case/displayCase/'+row.proId+'">'+row.proTitle+'</a></span>'
}},
{data: 'proLevel'},
{data: 'proIndustry'},
{data: 'proCompany'},
{data: 'proKeyword'},
{data: 'proFunction'},
{data: '',render:function (data, type, row, meta) {
return '<a href="/case/exportApproveCase/'+row.proId+'">导出<i class="fa fa-file-word-o" aria-hidden="true"></i></a>'
}}
]
});
}
})
});
使用render来扩展内容属性具体博客忘了粘贴了。
