如何解决带有colVis,colReorder和save状态的JQuery Datatable列过滤
我有一个使用JQuery DataTables插件的表。另外,我允许用户切换列可见性和拖动列。除非启用了saveState选项,否则一切都很好。
我的表格并未在所有列上进行过滤,但其中一些是某些列的输入字段,有些是下拉列表。
启用“状态保存”功能后,它将在可见字段上绘制过滤器,而不是同时考虑隐藏字段,因此过滤器与该列上显示的数据不匹配。
以下相关代码:
- 数据表选项:
sourceSets {
main {
resources {
srcDirs 'config'
}
}
}
- 将输入搜索添加到列标题:表初始化后:
tableElem = $('#detections_dt_table');
recordsDatatable = $(tableElem).DataTable(
{
dom: 'lBSrtip',buttons: [
{
extend: 'colvis',columns: ':not(.noVis)',text: '<i class="fas fa-eye"></i> ' + translations.columnVisibility,collectionLayout: 'two-column',className: 'btn btn-lg btn-dark'
}
],columnDefs: [] // 29 columns here,serverSide: true,processing: true,ajax: {} // Ajax to server side
colReorder: true,paging: true,info: true,searching: true,filter: true,ordering: true,pageLength: 25,pagingType: 'full_numbers',order: [[2,'desc']],stateSave: true,stateSaveParams: function (settings,data) {
// Clear filter search state save
for (let i = 0; i < data.columns.length; i++) {
delete data.columns[i].search;
}
}
});
- 将下拉列表添加到列过滤器:
// Add input search to column header
recordsDatatable .columns([1,3,4,5,7,8,9,12,14,19,20,21,22,23,24,26,27,28]).every(function (index) {
let title = $('#tableContainer thead tr:first th:eq(' + index + ')');
$(title).html("<div class='input-group'><input id='input" + index + "' type='text' class='form-control search-input' data-index='" + index + "' style='width:100%'/><button class=\"btn bg-transparent clear-filter\" style=\"margin-left: -40px; z-index: 100;\">\n" +
" <i class=\"fa fa-times\"></i>\n" +
" </button></div>");
let that = this;
$("#input" + index).on('keyup change',function () {
//prevent date update while clearing filters
let val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
//Visible index
let visIdx = $(this).parent().parent().index();
//Convert to data index (with colVisib and colReorder)
let dataIndex = recordsDatatable .column.index('fromVisible',visIdx);
if (!preventDataUpdate) {
recordsDatatable
.column(dataIndex)
.search(val)
.draw();
}
if (!detectionListFreeze) {
// Freeze view avoiding the update of the table
freezeView(true,true);
}
});
});
- 当我从服务器检索下拉过滤器值时,我使用以下代码加载每个过滤器:
//Show filters as dropdown
recordsDatatable .columns([6,10,11,13,15,16,17,18,29]).every(function (index) {
let column = this;
//create a unique id for the select control to load values.
let colDefs = recordsDatatable .settings().init().aoColumnDefs;
let filterId = 'filter-select-' + colDefs[index].name;
let elem = $('#tableContainer thead tr:first th:eq(' + index + ')');
$(elem)
.html('<select id="' + filterId + '" class="form-control filter-select" data-index="' + index + '"><option value="" data-icon="fa-filter">' + translations.All + '</option></select>');
$(elem).find('select').on('change',function () {
let visIdx = $(this).parent().index();
//Convert to data index (with colVisib and colReorder)
let dataIndex = recordsDatatable .column.index('fromVisible',visIdx);
let val;
switch (dataIndex) {
case 6:
val = $(this).val();
break;
default:
val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
break;
}
if (!preventDataUpdate) {
//Visible index
recordsDatatable
.column(dataIndex)
.search(val)
.draw();
}
// If freeze view is not enabled,freeze view
if (!detectionListFreeze) {
freezeView(true,true);
}
});
});
// TODO: Get filter data from server
//Load response data into select controls
loadFiltersResponseInSelects (response);
在隐藏某些列的同时,有什么想法可以调整其相应列上的过滤器吗?
谢谢。
