[英]How to Make Input Checkbox Update Price Total Using Values + Include Additional Fees for Total?
[英]how to add values of checkbox to get the total price
我正在创建一个包含一些服务及其价格的页面。 因此,当用户通过选中旁边的复选框来选择服务时,应将价格添加到总价格中。 另外,如果他未选中该复选框,则将从总费用中减去该服务的价格。
我已经尝试了许多方法,但无法获得结果。
这是我的代码。有人可以帮我做我想做的吗

尝试一下,它应该可以工作。这是此http://jsfiddle.net/sushilbharwani/QCndj/的jsfiddle
$('input[type=checkbox]').click(function(){
total = 0;
$('input[type=checkbox]:checked').each(function(){
total = total + parseInt($(this).val());
});
alert(total);
});
