jquery performing calculation on dynamically generated elements
- by user306472
I have a table made up of a row of 3 input elements: Price, Quanity, and Total. Under that, I have two links I can click to dynamically generate another row in the table. All that is working well, but actually calculating a value for the total element is giving me trouble. I know how to calculate the value of the first total element but I'm having trouble extending this functionality when I add a new row to the table. Here's the html:
<table id="table" border="0">
<thead>
<th>Price</th><th>Quantity</th><th>Total</th>
</thead>
<tbody>
<tr>
<td><input id ="price" type = "text"></input></td>
<td><input id ="quantity" type = "text"></input></td>
<td><input id ="total" type = "text"></input></td>
</tr>
</tbody>
</table>
<a href="#" id="add">Add New</a>
<a href="#" id="remove">Remove</a>
Here's the jquery I'm using:
$(function(){
$('a#add').click(function(){
$('#table > tbody').append('<tr><td><input id ="price" type = "text"></input></td><td><input id ="quantity" type = "text"></input></td><td><input id ="total" type = "text"></input></td></tr>');
});
$('a#remove').click(function(){
$('#table > tbody > tr:last').remove();
});
});
$(function(){
$('a#calc').click(function(){
var q = $('input#quantity').val();
var p = $('input#price').val();
var tot = (q*p);
$('input#total').val(tot);
});
});
I'm new to jquery so there's probably a simple method I don't know about that selects the relevant fields I want to calculate. Any guidance would be greatly appreciated.
