jQuery DataTable：在表头上搜索单个列
Posted
技术标签:
【中文标题】jQuery DataTable：在表头上搜索单个列【英文标题】：jQuery DataTable : Individual column searching on table header 【发布时间】：2017-03-27 01:48:48 【问题描述】：我已按照Individual column searching (text inputs) 和Individual column searching (select inputs) 上的步骤在jQuery DataTable 上使用多个过滤器，并且页脚上有多个过滤器。另一方面，我想将这些过滤器移动到 DataTable 的标题，但无法将它们水平对齐，如下图所示。有一些示例为Custom filtering - range search，但它们也没有对齐。是否有可能做到这一点？
$(document).ready(function()
// Setup - add a text input to each footer cell
$('#example tfoot th').each( function ()
var title = $(this).text();
$(this).html( '<input type="text" placeholder="Search '+title+'" />' );
);
// DataTable
var table = $('#example').DataTable();
// Apply the search
table.columns().every( function ()
var that = this;
$( 'input', this.footer() ).on( 'keyup change', function ()
if ( that.search() !== this.value )
that
.search( this.value )
.draw();
);
);
);
【问题讨论】：
@Gyrocode.com 你是真正的DataTable高手，能否请你帮我解决这个问题？在此先感谢... 是的，我们可以将此过滤器移到顶部... 【参考方案1】：这里solution你的问题请添加必要的东西数据表配置。
使用 CSS 将列过滤器从页脚移动到表头，即仅使用
<style>
tfoot
display: table-header-group;
</style>

希望对您有所帮助。
【讨论】：
抱歉，我正在处理另一个问题，刚刚尝试了您发布的解决方案。搜索输入位于标题上，但搜索参数 (sSearch) 作为 null 传递给控制器，而它可以通过标准搜索框传递。除此之外，当在标题的任何搜索框中输入单个字母时（默认搜索除外），控制器上的方法会被调用 8-9 次，而在默认搜索框中输入单个字母时仅调用一次.有什么想法吗？ 能否请您看看问题出在哪里并澄清我如何解决问题？感谢并投票+ datatables.net/plug-ins/api/fnFilterOnReturn 请试试这个对你有帮助 谢谢，但问题更多与发送参数有关，而不是在开始搜索时。有什么想法吗？ 我正在使用这个解决方案，但所有的搜索框都是相同的 - 宽度错误。如何调整宽度以使其与列宽匹配？【参考方案2】：这可以通过css来实现。
$(document).ready(function()
// Setup - add a text input to each footer cell
$('#example tfoot th').each( function ()
var title = $(this).text();
$(this).html( '<input type="text" placeholder="'+title+' Search" />' );
);
// DataTable
var table = $('#example').DataTable(
"paging": false,
"info": false,
"scrollY": 200,
"scrollX": true
);
// Apply the search
table.columns().every( function ()
var that = this;
$( 'input', this.footer() ).on( 'keyup change', function ()
if ( that.search() !== this.value )
that
.search( this.value )
.draw();
);
);

【参考方案3】：这里是数据表中单个列搜索的解决方案。 它还用于使用正则表达式进行多行值搜索：
$('#' + tableId + ' thead tr').clone(true).appendTo('#' + tableId + ' thead');
$('#' + tableId + ' thead tr:eq(1) th').each(function (i) // Creating Clone Header for Filter TextBox
var title = $(this).text();
if (excludeTitle.indexOf(title.trim()) == -1) // check table column header to add filter textBox
$(this).html('<input type="text" id="col' + i + '_filter" class="ClearFilters" placeholder="Search ' + title + '" />');
$('input', this).on('keyup change', function ()
if (table.column(i).search() !== this.value)
var sp1 = this.value;
var regex_check = null;
try regex_check = new RegExp(sp1);
catch (error) alert('Search parameter is not in correct format.'); return false;
table.column(i).search(sp1, true).draw();
);
else
$(this).html('');
);【讨论】：
【参考方案4】：你可以试试this DataTables plug-in，看起来很合适，虽然界面和你需要的有些不同。

【参考方案5】：// Setup - add a text input to each footer cell
$('#example thead th').each( function ()
var title = $(this).text();
$(this).html( '<input type="text" placeholder="Search '+title+'" />' );
);
// DataTable
var table = $('#example').DataTable();
// Apply the search
table.columns().every( function ()
var that = this;
$( 'input', this.header() ).on( 'keyup change clear', function ()
if ( that.search() !== this.value )
that
.search( this.value )
.draw();
);
);【讨论】：
很抱歉，您的 sn-p 无法正常工作。也许你忘了包含对 jQuery 的引用？【参考方案6】：在您的代码中使用this.header() 而不是this.footer()
喜欢：
$( 'input', this.header() ).on( 'keyup change', function ()
// your code
);
希望它对你有用。

【参考方案7】：$(document).ready(function()
// Setup - add a text input to each footer cell
var table = $('#example').DataTable(
orderCellsTop: true,
fixedHeader: true
);;
$("#example thead tr td").each( function ( i )
var select = $('<select><option value=""></option></select>')
.appendTo( $(this).empty() )
.on( 'change', function ()
table.column( i )
.search( $(this).val() )
.draw();
);
table.column( i ).data().unique().sort().each( function ( d, j )
select.append( '<option value="'+d+'">'+d+'</option>' )

你能解释一下这是如何回答这个问题的吗？以上是关于jQuery DataTable：在表头上搜索单个列的主要内容，如果未能解决你的问题，请参考以下文章
