Question

I’m trying really hard to learn how to loop through rows in a jQuery dataTable, not doing too terribly well.

My table id is “partslist”. So:

    $("#partslist tr").each(function() {
        $($(this) + " td").each(function() {
            alert($(this).text());
        })
    })

You can see that the:

$($(this) + ” td”).each …

is a big fat failure. I want to loop through the columns in each row. It’s funny, with all those examples on the dataTables website, I can’t find a single one that would let me get the data from the table easily.

Answer 1

you can do this:

$("#partslist tr").each(function() {
        $(this).find("td").each(function() {
            alert($(this).text());
        })
    })

which finds all of the td’s in selection of tr’s

or this

$("#partslist tr").each(function() {
        $("td",$(this)).each(function() {
            alert($(this).text());
        })
    })

which finds all the td’s using the selection of tr’s as the scope or “context”

These both accomplish the same thing.
