问题描述
我一直试图在过滤后得到我的表的行数,但是我甚至不能让它以最初的行计数回应。
我的表格是通过HTML5渲染,由PHP填充,这些都可以正常工作。
< table id =table_booksclass =table datatabledata-searchplaceholder =搜索书籍...data-margindifference =70>
< thead>
< tr>
< th style =width:30px;>< i class =fa fa-codetitle =click>< / i>< / th&
< Th> Column1< / th>
< Th> Column2< / th>
< Th> Column3< / th>
< th class =text-right hidden-xsstyle =width:20%>细节< / th>
< / tr>
< / thead>
< tbody>
<?php echo $ contenthtml; ?>
< / tbody>
< / table>
我发现说这个工作在1.9中的文档,但是我收到一个无效的功能
$(document).ready(function(){
var btable = $('#table_books')DataTable();
var b_table_count = btable ._('tr',{filter:applied});
console.log(b_table_count);
});
解决方案
使用 page.info()
获取有关表的分页信息的API方法。 p>
它返回一个对象,例如:
{
page:1,
pages:6,
start:10,
end:20,
length :10,
recordsTotal:57,
recordsDisplay:57
}
用法:
function getNumFilteredRows(id){
var info = $(id).DataTable()。page.info();
return info.recordsDisplay;
}
I have been trying to get the row count of my table after filtering, but I can't even get it to respond back with the row count initially.
My table is rendered via HTML5 and populated by PHP which all works correctly.
<table id="table_books" class="table datatable" data-searchplaceholder="Search books..." data-margindifference="70" >
<thead>
<tr>
<th style="width:30px;"><i class="fa fa-code" title="click"></i></th>
<th>Column1</th>
<th>Column2</th>
<th>Column3</th>
<th class="text-right hidden-xs" style="width:20%">Details</th>
</tr>
</thead>
<tbody>
<?php echo $contenthtml; ?>
</tbody>
</table>
I found documentation that says this works in 1.9, but I get an invalid function
$(document).ready(function() {
var btable = $('#table_books').DataTable();
var b_table_count = btable._('tr', {"filter":"applied"});
console.log(b_table_count);
});
解决方案
Use page.info()
API method to get paging information about the table.
It returns an object, for example:
{
"page": 1,
"pages": 6,
"start": 10,
"end": 20,
"length": 10,
"recordsTotal": 57,
"recordsDisplay": 57
}
Usage:
function getNumFilteredRows(id){
var info = $(id).DataTable().page.info();
return info.recordsDisplay;
}
