How to iterate a table rows with JQuery and access some cell values?
提问by Sergio del Amo
<table class="checkout itemsOverview">
<tr class="item">
<td>GR-10 Senderos</td>
<td><span class="value">15.00</span> </td>
<td><input type="text" value="1" maxlength="2" class="quantity" /></td>
</tr>
<tr class="item">
<td>GR-10 Senderos<br/>GR-66 Camino de la Hermandad<br/>GR 88 Senderos del Jarama<br/>Camino del Cid</td>
<td><span class="value">45.00</span> </td>
<td><input type="text" class="quantity" value="1" maxlength="2"/></td>
</tr>
</table>
I was trying with the next code to get the value and quantity of each item.
我正在尝试使用下一个代码来获取每个项目的价值和数量。
$("tr.item").each(function(i, tr) {
var value = $(tr + " span.value").html();
var quantity = $(tr + " input.quantity").val();
});
It is not working. Can anyone help me?

回答by Rolwin Crasta
try this
尝试这个
var value = iterate('tr.item span.value');
var quantity = iterate('tr.item span.quantity');
function iterate(selector)
{
var result = '';
if ($(selector))
{
$(selector).each(function ()
{
if (result == '')
{
result = $(this).html();
}
else
{
result = result + "," + $(this).html();
}
});
}
}
