jQuery DataTables添加自定义多个搜索条件

效果如下：

一、在前台页面定义输入搜索条件的文本框

 <div class="ibox-tools">
                            <span>年度span>
                            @Html.DropDownList("year", (List<SelectListItem>)ViewBag.YearDrop, new { @class = "" })
                            <span>月度span>
                            @Html.DropDownList("month", (List<SelectListItem>)ViewBag.MonthDrop, new { @class = "" })
                            <span>开始日期span>
                            @Html.TextBox("StartTime", null, new { @class = "m-wrap small" })
                            <span>结束日期span>
                            @Html.TextBox("EndTime", null, new { @class = "m-wrap small" })

                            <span>发文类型span>
                            @Html.DropDownList("DTMName", null, new { @class = "m-wrap small" })
                            <span>关键字span>
                            @Html.TextBox("KeyWords", null, new { @class = "m-wrap small" })

                            <a class="btn btn-primary btn-sm" title='搜索' id="btn_search" href="javascript:void(0)"><i class="fa fa-search">i>搜索a>
                            <a class="btn btn-primary btn-sm" title='发文' href="@Url.Action("Create")"><i class="fa fa-plus">i>添加a>

                            <a class="collapse-link">
                                <i class="fa fa-chevron-up">i>
                            a>
                        div>

二、最主要的是js部分

  //把公共的设置项都放在这里，就不需要每个页面都设置一遍了，放在jQuery对象上是为了避免污染全局变量
    $.dataTablesSettings = {
        "aLengthMenu": [10, 25, 50, 100],
        "bAutoWidth": false,
        "bDeferRender": true,
        "bLengthChange": true,
        "sAjaxSource": "/ReceivedDoc/AjaxHandler",
        "bPaginate": true,
        "bServerSide": true,
        "bSort": true,
        "iDisplayLength": 10,
        searching: false,//是否显示搜索框
        "aaSorting": [[0, "asc"]], // set first column as a default sort by asc
        "bFilter": true,
        "aoColumnDefs": [{  // define columns sorting options(by default all columns are sortable extept the first checkbox column)
            'bSortable': true,
            'aTargets': [0, 8]
        }],
        "fnServerParams": function (aoData) {
            aoData._rand = Math.random();
        },
        "fnDrawCallback": function () {

        }


        dataTable = $(".dataTables-example").dataTable($.dataTablesSettings);
            $('#btn_search').click(function () {
                //这里重新设置参数
                $.dataTablesSettings.fnServerParams = function (aoData) {
                    aoData._rand = Math.random();
                    aoData.push(
                        { "name": "year", "value": $('#year').val() },
                        { "name": "month", "value": $('#month').val() },
                        { "name": "StartTime", "value": $('#StartTime').val() },
                        { "name": "EndTime", "value": $('#EndTime').val() },
                        { "name": "DTMName", "value": $('#DTMName').val() },
                        { "name": "KeyWords", "value": $('#KeyWords').val() }
                        );
                }
                //搜索就是设置参数，然后销毁datatable重新再建一个
                dataTable.fnDestroy(false);
                dataTable = $(".dataTables-example").dataTable($.dataTablesSettings);
                //搜索后跳转到第一页
                dataTable.fnPageChange(0);
            });

三、后台就就可以使用类接收参数了，也可以使用HttpContext.Request.QueryString["year"]接收。接收后根据不同的查询条件进行相应的查询。
