count or sum of checked boxes in a table

Posted on 2013-05-09

I have a table setup with two columns (side1 and side2).
<table border = "1" width="100%" id="Table1">
<td class = 'Side1'>checkbox is here</td>  <td class = 'Side2'>checkbox is here</td>

I need to make sure that at least one checkbox is checked on side1 and at least one is checked on side2.

I tried the following but I am getting a syntax error somewhere...I don't even know if this would be the correct way to do it.

``````        var sideTotal = [];
\$('#table1 .Side1').each(function(){
sideTotal[0]+= \$(this) :checked.val();
});
``````

``````var sideTotal = [];
var n = \$('.Side1,.Side2', '#table1').size();
sideTotal[0] = n;
``````

Would't this return the count of all "Side1" and "Side2", regardless of checked or not?

Well, if it does, then I have a bigger problem because I get an alert with zero.

Try this :
``````var sideTotal = [];
var n = \$('.Side1,.Side2', '#Table1').find(":checkbox:checked").size();
sideTotal[0] = n;
``````

I needed each one seperately, but that gave me what I needed.  Thanks.
``````        var canContinue = 1;
var n
n = \$('.Side1', '#Table1').find(":checkbox:checked").size();
if (n == 0) {
alert('You need to select at least one item in the first column');
canContinue = 0;
}

n = \$('.Side2', '#Table1').find(":checkbox:checked").size();
if (n == 0) {
alert('You need to select at least one item in the second column');
canContinue = 0;
}
``````
