Question

I have the following jQuery:

$.fn.dataTableExt.afnSortData['dom-text'] = function (oSettings, iColumn) {
    var aData = [];
    $('td:eq(' + iColumn + ') input', oSettings.oApi._fnGetTrNodes(oSettings)).each(function () {
        aData.push(this.value);
    });
    return aData;
}

I’m using this to get the value of the input in td elements.

However my HTML now looks like this:

<td id="tempRowKey_117" class=" sorting_1" data-rk="100001">  
   <input type="text" value="10.0.1" id="TempRowKey_117">
</td>

How can I change my jQuery so that it now gets the value of data-rk instead of the value of the input?

In other words I want to get “10001”

Answer 1

$.fn.dataTableExt.afnSortData['dom-text'] = function (oSettings, iColumn) {
    var aData = [];
    $('td:eq(' + iColumn + ')', oSettings.oApi._fnGetTrNodes(oSettings)).each(function () {
        aData.push($(this).attr('data-rk'));
    });
    return aData;
}
