Re: Editable Invoice –including tax to total

[jfreehill]

Forget that last post, I should’ve looked at what you were actually using. Sorry about any confusion caused. All you need to do is add a bit to update_total and a small event checker for the checkbox. Below is the code you should actually use:

function update_total() {

var total = 0, tax = 0, taxRate = 0.0575;



$('.price').each(function(i){

price = $(this).html().replace("$","");

if (!isNaN(price)) total += Number(price);

});

total = roundNumber(total,2);

$('#subtotal').html("$"+total);



//will change value of total only if taxbox is checked, otherwise

//it will subtract tax from the total, which defaults to 0

if($('#taxbox:checked')) {

tax = total * taxRate;

total += roundNumber(tax,2);

} else {

total -= tax;

}

$('#total').html("$"+total);



update_balance();

}

Then, towards the bottom of the script where all the other event handlers are inside the document ready function, put this:

  $('#taxbox').change(function(){

update_total();

});

Hopefully that works correctly. You may want to add a box the html to show what the tax is or note the addition of taxes just so anybody else seeing it isn’t confused.
