Question

I have a table

<table>
       <tr class="PO1"></tr>
       <tr class="PO2"></tr>
       <tr class="PO3"></tr>
</table>

How can I loop through all tr with class "PO1" and get the value of each 'td' value?

$("table#id tr .PO1").each(function(i)
{
    // how to get the td values??
});

Answer 1

var values = $('table tr.PO1 td').map(function(_, td) {
    return $(td).text();
}).get();

This would just create an array with the text contents from each td. Probably a better idea to use a map/object instead:

var values = $('table tr.PO1 td').map(function(index, td) {
    var ret = { };

    ret[ index ] = $(td).text();
    return ret;
}).get();
