我有一个数据表，其中显示了来自数据库的数据。 我在表格上应用日期过滤器，如下所示，
<script >
$(document).ready(function() {
var d = new Date();
var month = d.getMonth()+1;
var day = d.getDate();
var output = d.getFullYear() + '/' +
(month<10 ? '0' : '') + month + '/' +
(day<10 ? '0' : '') + day;
} );
$.fn.dataTable.ext.search.push(
function( settings, data, dataIndex ) {
var min = Date.parse($('#min').val());
var max = Date.parse($('#max').val());
var age = Date.parse( data[1] ) || 0; // use data for the age column
//console.log(min);
if ( ( isNaN( min ) && isNaN( max ) ) ||
( isNaN( min ) && age <= max ) ||
( min <= age && isNaN( max ) ) ||
( min <= age && age <= max ) )
{
return true;
}
return false;
}
);
$(document).ready(function() {
var table = $('#example').DataTable();
// Event listener to the two range filtering inputs to redraw on input
$('#min, #max').keyup( function() {
table.draw();
} );
} );
</script>
用于过滤器的HTML
<div class="datewise_filter " id="datewise_filter" >
<label>From:</label>
<input type="date" name="min" id="min" >
<label>To:</label>
<input type="date" id="max" name="max">
</div>
表格-
<table id="example" class="display nowrap cell-border" style="width:100%">
<thead>
<tr>
//headers
</tr>
</thead>
<tbody>
//body
</tbody>
</table>
但是当我输入日期时，我必须按Enter键，然后显示数据， 而不是像ajax这样的动态重载。
我遵循了以下教程， https://datatables.net/examples/plug-ins/range_filtering.html
在这种情况下，当用户输入最大年龄时，将根据相关数据自动重新加载数据表，但是在我的代码中，当我输入max后，必须按Enter键。
当我在
中进行console.log(min);时
$.fn.dataTable.ext.search.push
我明白了，
（1715）NaN
我正面临2次违规行为，
[Violation]'setTimeout'处理程序花费了1764ms
[Violation]执行JavaScript时的强制重排花费了1048ms
我在这里做错了，谢谢您的建议

@Hi Mach2，
代码中的第一个问题是，您已在数据表外部声明了最小，最大输入。只需将代码更改为类似documentation中所述的代码即可。因为当keyup被调用时，它没有发现min max的值改变。但是，当您按Enter键时，它将提交输入，并重新加载数据表。
如果以上信息。还不够，请尝试以下内容：
尝试更改对keyup函数的调用，如下所示，可能是您的问题得到了解决：
$('#min, #max').on( "keyup", 'input', function() {
table.draw();
});
还要检查您是否使用正确的html结构，就像它们在数据表中的第一个tbody中声明了min max输入一样。希望这会帮助您理解。
这是demo
如果您有任何疑问，请在评论中告诉我。

您使用的代码是developmental search plugin，用于遍历现有表，但是听起来您正在尝试访问数据库，因此您需要使用server-side processing来设置数据表。
一旦正确设置了表，就可以操纵search parameters来过滤数据。
