需要你的帮助
所以我有一个贝宝形式,也有两个单选按钮。一个具有运输价值,一个没有。这是实际表格的链接 http://www.topchoicedata.com/test.php
我想要发生的是,如果一个人选择了第一个收音机盒(" $ 19.99运输 - DATABASE SENT ON CD ROM"),那么19.99会自动添加到" hdwppamount&# 34;金额设定为175美元,因此当该人按下"现在支付"时,它将在paypal页面上总计$ 194.99。
如果该人选择了第二个选项("免费送货 - 数据库通过电子邮件发送"),那么当然没有任何价值被添加到" hdwppamount"金额和175美元将是paypal页面的总数。
现在,如果用户选择on或其他选项,代码可以正常工作,然后不会在决定选择哪一个的单选按钮之间切换。因此,如果我选择第一个选项,然后决定第二个选项,依此类推等等,我要么得到一个错误页面,或者如果我确实选择了免费选项,那么19.99仍然会被添加。
我需要这样,如果选择了第一个选项,则会添加19.99,如果选择了第二个选项,则不会添加任何内容。
任何帮助将不胜感激。

答案 0 :(得分:0)
使用收音机,您一次只能检查其中一个。这意味着您必须测试在指定时刻检查哪一个(即:更改事件)。
我将输入字段hdwppamount从隐藏更改为片段中的文本以清除行为。
$(function () {
$('#shipping, #noshipping').on('change', function(){
var hdwppamount = Number($("#hdwppamount").val());
var shippingcost = 19.99;
if (this.id == 'noshipping') { // shipping unchecked
$("#hdwppamount").val(hdwppamount-shippingcost);
} else { // shipping checked
$("#hdwppamount").val(hdwppamount+shippingcost);
}
});
// initialize the field with the correct value
$("#hdwppamount").val('194.99');
});
