无法按 DataTable 中的列显示过滤器
Posted
技术标签:
【中文标题】无法按 DataTable 中的列显示过滤器【英文标题】:unable to display the filter by columns in DataTable 【发布时间】:2021-10-27 21:32:23 【问题描述】:我正在使用数据表,它需要具有基于单个列的搜索功能以及全局搜索 我正在使用二维数组。
它确实放置了搜索框,但它没有进行正确的搜索而不是进行良好的全局搜索
我试过了

var dataHere = [

$(document).ready(function()
var html = ''
for (var j = 0; j < dataHere[0].length; j++)
html = html + '<td><input type="' + dataHere[0][j] + '" placeholder="Search ' + dataHere[0][j] + '" /></td>'
$("#example thead tr").html(html);
// DataTable
var table = $('#example').DataTable(
"data": dataHere,
initComplete: function()
$('#example thead th').each(function()
var title = $(this).text();
$(this).html('<input type="text" placeholder="Search ' + title + '" />');
);
this.api().columns().every(function()
var that = this;
$('input', this.footer()).on('keyup change clear', function()
if (that.search() !== this.value)
that
.search(this.value)
.draw();
);
);
);
);
);

我需要像这样实现,但是搜索框需要在顶部

【问题讨论】:
【参考方案1】:我从你的出发点做了一些修改。最终结果:
var dataHere = [
["Name", "Role", "Place", "Extn.", "Date"],
[
"Tiger Nixon",
"System Architect",
"Edinburgh",
"5421",
"2011/04/25",
],
[
"Garrett Winters",
"Director",
"London",
"8422",
"2011/07/25",
]
];
$(document).ready(function()
// build 2 headers - the 1st for sorting, the 2nd for filtering:
var head1 = '<tr>';
var head2 = '<tr>';
for (var j = 0; j < dataHere[0].length; j++)
head1 = head1 + '<th>' + dataHere[0][j] + '</th>';
head2 = head2 + '<th><input type="'
+ dataHere[0][j]
+ '" placeholder="Search '
+ dataHere[0][j] + '" /></th>';
head1 = head1 + '</tr>';
head2 = head2 + '</tr>';
$("#example thead").html(head1 + head2);
var table = $('#example').DataTable(
data: dataHere.slice(1),
orderCellsTop: true,
initComplete: function()
// add event handlers to each of our column filters:
$('#example thead tr:eq(1) th').each( function (i)
$( 'input', this ).on( 'keyup change', function ()
if ( table.column(i).search() !== this.value )
table.column(i).search( this.value ).draw();
);
);
);
);

我所做的主要更改:
确保dataHere
行数据在值数量和数据类型方面与标题数据匹配。
为方便起见,提供带有空 <thead>
和 <tbody>
标记的起始 HTML 结构(使 JavaScript 代码更容易一些)。
在 JavaScript 中,构建 2 个标题行。这是为了确保排序事件与过滤事件完全分开。否则,如果 DataTable 中只有一个标题行,则每次尝试过滤时都会排序。
在 DataTable 定义中包含 orderCellsTop: true
。从第 (3) 点开始,这告诉 DataTables 只有表中的第一个标题行用于排序。
删除了不需要的代码。因为您正在预先构建 HTML 表,所以您已经有了所需的过滤器 - 您无需在 DataTable 初始化代码中重复该逻辑。

【参考方案2】:这行得通。
$(document).ready(function()
// Setup - add a text input to each footer cell
$('#example tfoot th').each(function()
var title = $('#example thead th').eq($(this).index()).text();
$(this).html('<input type="text" placeholder="Search ' + title + '" />');
);
// DataTable
var table = $('#example').DataTable();
// Apply the search
table.columns().eq(0).each(function(colIdx)
$('input', table.column(colIdx).footer()).on('keyup change', function()
table.column(colIdx)
.search(this.value)
.draw();
);
);
);
#example tfoot
display: table-header-group;
