从一个按钮中单击数据表中的数据访问一行 [英] Accessing data in a DataTable from a button click within a row

问题描述

我可以通过以下简单的方法访问数据行：

I can access the data row by the following simple method:

$('#received-body tr').click( function(){
    aData = received_table.fnGetData(this);
    selected_received_id = aData[0];
    alert( selected_received_id );
});

但是我无法从名为 .received-update的按钮访问它们其中一行：

but I can't access them from the button called .received-update in one of the rows:

$('#received-body .received-update').click( function(){
    alert( 'update' ); // works
    aData = received_table.fnGetData( $(this).parents('tr')); // fails
    selected_received_id = aData[0];
    alert( 'update:' + selected_received_id );                      
});

任何帮助赞赏

推荐答案

您可以通过替换

    aData = received_table.fnGetData($(this).parents('tr'));

与

    aData = received_table.fnGetData($(this).parents('tr')[0]);

调用 received_table.fnGetPosition（）
