javascript - 数据表 fnSort 建议

Question

正在寻求一些帮助，了解如何将 fnSort 与此数据表代码一起放置，以使默认排序第二列而不是第一列。我有:

dataClones['keyword_table_<?php echo ceil($countCallsCounter/7); ?>']=document.getElementById('keyword_table_<?php echo ceil($countCallsCounter/7); ?>').cloneNode(true);

    $('#keyword_table_<?php echo ceil($countCallsCounter/7); ?>').dataTable( {
    //"sDom": "<'row'<'span6'l><'span6'f>r>t<'row'<'span6'i><'span6'p>>",
    "sDom":"<<'span6'l><'span6'f>r>t<<'span6'i><'span6'p>>",
    "sPaginationType": "bootstrap",
    "oLanguage": {
    "sLengthMenu": "_MENU_ records per page"
    }

} 
);

我知道我需要添加http://datatables.net/api#fnSort但我对 JS 不太熟悉，所以如果可能的话，需要一些快速帮助。

谢谢

您所要做的就是为 $(selector).datatable() 调用设置一个变量 = 。然后就可以调用variable.fnSort()了。

var oTable; // Make sure this is within scope of your function, or where you want to execute the sort.

dataClones['keyword_table_<?php echo ceil($countCallsCounter/7); ?>']=document.getElementById('keyword_table_<?php echo ceil($countCallsCounter/7); ?>').cloneNode(true);

    oTable = $('#keyword_table_<?php echo ceil($countCallsCounter/7); ?>').dataTable( {
    //"sDom": "<'row'<'span6'l><'span6'f>r>t<'row'<'span6'i><'span6'p>>",
    "sDom":"<<'span6'l><'span6'f>r>t<<'span6'i><'span6'p>>",
    "sPaginationType": "bootstrap",
    "oLanguage": {
    "sLengthMenu": "_MENU_ records per page"
    }

} 
);

function onSort(){
    oTable.fnSort([0,'asc']);
}

此外，如果您知道在初始化数据表时要排序的列，您可以:

$('#example').dataTable( {
    "aaSorting": [[ 4, "desc" ]]
} );
