我想将earning
列值与代码末尾的总和相加。我正在使用Jquery datatable
按此代码过滤记录,但无法为总数编写代码。我还tried footer callback of datatable
但未获得所需的结果。
<script src="media/js/jquery-1.4.4.min.js" type="text/javascript"></script>
<script src="media/js/jquery.dataTables.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript" src="media/js/jquery.dataTables.js"></script>
<script src="media/js/jquery-ui.js" type="text/javascript"></script>
<script src="media/js/jquery.dataTables.columnFilter.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$.datepicker.regional[""].dateFormat = 'dd/mm/yy';
$.datepicker.setDefaults($.datepicker.regional['']);
$('#example').dataTable({
"aoColumns": [{},

} )
.columnFilter({ sPlaceHolder: "head:before",
aoColumns: [ { type: "hidden" },

],
"fnFooterCallback": function ( nRow, aaData, iStart, iEnd, aiDisplay ) {
/*
* Calculate the total market share for all browsers in this table (ie inc. outside
* the pagination)
*/
var iTotalMarket = 0;
for ( var i=0 ; i<aaData.length ; i++ )
{
iTotalMarket += aaData[i][11]*1;
}

{
iPageMarket += aaData[ aiDisplay[i] ][11]*1;
}
/* Modify the footer row to match what we want */
var nCells = nRow.getElementsByTagName('th');
nCells[1].innerHTML = parseInt(iPageMarket * 100)/100 +
'% ('+ parseInt(iTotalMarket * 100)/100 +'% total)';

以下是解决方案: - 使用页脚回调函数执行此操作。 每次抽奖都会运行此回调。因此,无论何时更改表的内容,此函数都会运行并更改页面总薪水。
<div class="container">
<table cellpadding="0" cellspacing="0" border="0" class="dataTable" id="example">

看起来你在columnFilter init选项中定义了你的页脚回调,而不是在dataTable init选项中定义 - 我不希望它在那里工作。
