Question

I need to go through a few <tr>s (I don’t know the exact number beforehand since they are generated on the fly), where I have a few dropdowns. The names of dropdowns are set as item_size[], item_set[] and item_quantity[]. I need to get their value onsubmit.

I understand that I need to use each function here, like $('tr.item').each(function(){ to go through them and then need to find a way to get values chosen in each of the three dropdowns.

Any idea here ?
Thanks.

<tr class="item">
    <td>some stuff</td>
    <td><select name = "item_size[]" ...><option>...</option><option>...</option></select></td>
    <td><select name = "item_set[]" ...><option>...</option><option>...</option></select></td>
    <td>some stuff</td>
    <td><select name = "item_quantity[]" ...><option>...</option><option>...</option></select></td>
    <td>some stuff</td>
</tr>
<tr class="item">
    <td>some stuff</td>
    <td><select name = "item_size[]" ...><option>...</option><option>...</option></select></td>
    <td><select name = "item_set[]" ...><option>...</option><option>...</option></select></td>
    <td>some stuff</td>
    <td><select name = "item_quantity[]" ...><option>...</option><option>...</option></select></td>
    <td>some stuff</td>
</tr>
<tr class="item">
    <td>some stuff</td>
    <td><select name = "item_size[]" ...><option>...</option><option>...</option></select></td>
    <td><select name = "item_set[]" ...><option>...</option><option>...</option></select></td>
    <td>some stuff</td>
    <td><select name = "item_quantity[]" ...><option>...</option><option>...</option></select></td>
    <td>some stuff</td>
</tr>

var inputs = new Array();
$("tr.item").each(function() {
    var tr_inputs = new Array();
    $(this).find("select").each(function() {
        tr_inputs[$(this).attr("name")] = $(this).val();
    });
    inputs.push(tr_inputs);
});
console.log(inputs);

You can retrieve the values for each item from the array inputs. Each item consists of 3 key value pairs for item_size[], item_set[] and item_quantity[].
