Question

I have several tables which looks like these below:

<table id="table1">
<tr>
    <th>Item</th>
    <th>Price</th>
</tr>
<tr>
    <td>Item 1</a></td>
    <td><input type="text" name="sum1" id="sum1" /></td>
</tr>
<tr>
    <td>Item 2</a></td>
    <td><input type="text" name="sum2" id="sum2" /></td>
</tr>
<tr>
    <td>Item 3</td>
    <td><input type="text" name="sum3" id="sum3" /></td>
</tr>
<tr>
    <td>&nbsp;</td>
    <td>Total:</td>
    <td>$total </td>
</tr>
</table>



<table id="table2">
<tr>
    <th>Item</th>
    <th>Price</th>
</tr>
<tr>
    <td>Item 1</a></td>
    <td><input type="text" name="sum1" id="sum1" /></td>
</tr>
<tr>
    <td>Item 2</a></td>
    <td><input type="text" name="sum2" id="sum2" /></td>
</tr>
<tr>
    <td>Item 3</td>
    <td><input type="text" name="sum3" id="sum3" /></td>
</tr>
<tr>
    <td>Item 4</td>
    <td><input type="text" name="sum4" id="sum4" /></td>
</tr>
<tr>
    <td>&nbsp;</td>
    <td>Total:</td>
    <td>$total</td>
</tr>
</table>

Does anybody know if there is a possibility to sum item prices for each input (seperately for table1, table2, etc..)
And at the end print sum of items from all items?

You’ll need a dom manipulator like jQuery or simply javascript. I’d give the fields a class to make it even easier–say, “sum”. Then you can grab all the children “sum”s from the parent tables. Parse their value to an int and add. Not too bad.

Here’s a working JS fiddle example
