We need to calculate column value when we are working with items that having respective prices for each row. So at bottom we can calculate total price.
HTML :
<b>Calculate Total Item Price</b>
<table border=”1″>
<tr><td>Items Name</td><td>Price</td></tr>
<tr><td>Item1</td><td>49</td></tr>
<tr><td>Item2</td><td>1211</td></tr>
<tr><td>Item3</td><td>1</td></tr>
<tr><td>Item4</td><td>12</td></tr>
</table>
JS:
$(document).ready(function(){
var result = [];
$(‘table tr’).each(function(){
$(‘td’, this).each(function(index, val){
if(!result[index]) result[index] = 0;
result[index] += parseInt($(val).text());
});
});
$(‘table’).append(‘<tr></tr>’);
$(result).each(function(){
$(‘table tr’).last().append(‘<td>’+this+'</td>’)
});
});
