How to add numbers from dynamic input fields?
Question
I'm basically working on a form right now. But my form has "add" and "delete" buttons to accommodate extra fields. Now, one of the fields is a "total budget" field.
I'm going to send all input fields to another page. But, I want to be able to add up complete total amount from all "total budget" fields. (Keep in mind, there is one total budget field, but the user can "add"/"delete" and there could be more).
When I pass it to the next page, I want to pass them individually, and keep them as so for display. On the next page there will be an extra "final total amount" which I will display that.
Also, I'm using foundation 5 (Not sure if that matters).
Now, I'm not sure how to do this. Can some one point me towards the right way? Here's what my mark up looks like:
JAVASCRIPT:
<script>
$(document).ready(function() {
$(".add").on('click', function() {
var linehtml = $('.line').html();
var total = $('.line').length;
var dele = (total - 1);
$('#linecont').append('<div class="line"><hr />'+linehtml+'</div>');
return false;
});
$(".del").on('click', function() {
var linecont = $("#linecont");
var total = linecont.find('.line').length;
var dele = (total - 1);
if(total === 1) {
return false;
}
$('.line').eq(dele).remove();
return false;
});
});
</script>
HTML:
<div align="center">
<a href="#" class="button add">Add Line</a>
<a href="#" class="button del">Delete Line</a>

Assuming the value in Total Budget is not a string and you dont need to parse it away from currency prefixes etc...:
var totalBudget = 0;
$("input[placeholder='Total Budget']").each(function() {
totalBudget += $(this).val();
});

You could have a "Grand Total" hidden input field in your HTML
<input type="hidden" id="grand-total" name="grand-total"/>
You can pass its value with the other input values when you go to the next page
Add a class="total-budget" to the "Total Budget" input fields, and a javascript function which calculates the grand total
function computeGrandTotal() {
var grandTotal = 0;
$(".total-budget").each(function () {
var total = $(this).val();
if ($.isNumeric(total)) {
grandTotal += parseFloat(total);
}
});
$('#grand-total').html(grandTotal);
}
Trigger the computeGrandTotal() function when you go to the next page
<a onclick="computeGrandTotal()" href="#">Go to next page</a>
