每当按下按钮(按钮不在此代码中)时,我都会尝试进行计数功能。计数的结果应该在只读文本字段中。
var html='';
var huidig = 0;
$('body').off('click', '[data-type=product]').on('click', '[data-type=product]', function(e)
{
e.preventDefault();
var price = $(this).attr('data-price');
var name = $(this).attr('data-name');
var id = $(this).attr('data-id');
if($('input[value='+id+']').length > 0)
{
var parent = $('input[value='+id+']').parent();
console.log("parent: " + parent);
var currentValue = parseFloat(parent.find('input[name^=product_amount]').val());
console.log("currentValue: " + currentValue);
currentValue++;
console.log("currentValue: " + currentValue);
parent.find('input[name^=product_amount]').val(parseFloat(currentValue));
console.log(parent.find('input[name^=product_amount]').val(parseFloat(currentValue)));
}
else
{
html+='<div class="row-fluid"><div class="span1"><input type="hidden" name="product[]" value="'+id+'"/><input type="text" readonly="readonly" name="product_amount[]" value="0" /></div> <div class="span7">'+name+'</div> <div class="span3 offset1">€'+price+'</div> </div>';
}
$('.bill').html(html);
amount = amount + parseFloat(price);
$('.total_bill').html(amount.toFixed(2));
});
