我正在使用带有工具提示的数据表。我正在使用隐藏列来显示工具提示。它工作正常，但它在表格的每个单元格上显示工具提示。如果单元格值为空，是否可以隐藏工具提示。请在此处查看我的示例 - https://live.datatables.net/lerapaho/5/edit
在我的示例中，第一行不应显示有关年龄和某事列的工具提示，第二行不应显示有关开始日期和薪水的工具提示。任何帮助/建议表示赞赏。谢谢。
$(document).ready(function() {
// Just assign to the global table variable
// Nothing else is changed in here
table = $('#example').DataTable({
paging: false,
scrollX: true,
scrollCollapse: true,
lengthChange: false,
searching: true,
ordering: false,
fixedColumns: {
left: 1
},
columnDefs: [
{
"targets": [2],
"visible": false,
"searchable": true }
],
rowCallback: function(row, data, displayNum, displayIndex, dataIndex) {
$(row).attr('title', data[2]);
},
initComplete: function() {
$.fn.dataTable.ext.search.push(
function(settings, searchData, index, rowData, counter) {
// Don't display rows if nothing is checked
if (filtered.length === 0) {
return true;
} else if (filtered.includes(searchData[15])) {
return true;
}
return false;
}
);
}
});
/* Nothing in here was changed */
$('.filter').on('change', function() {
var val = $(this).val();
var checked = $(this).prop('checked');
var index = filtered.indexOf(val);
if (checked && index === -1) {
filtered.push(val);
} else if (!checked && index > -1) {
filtered.splice(index, 2);
}
table.draw();
});
