Question

这是我的JS代码，它计算总金额：

function calTotal()
{
var a=250.00, b=175.00, c=90.00, d=415.00, e=225.00, f=225.00, g=225.00, h=225.00; 
var sum = 0.00;

    if(booking_form.faat_item1.checked == true){
        booking_form.faat_item1.value = a;
        sum += a;
        }
    else
        booking_form.faat_item1.value = 0;

    if(booking_form.faat_item2.checked == true){
        booking_form.faat_item2.value = b;
        sum += b;
        }
    else
        booking_form.faat_item2.value = 0;

    if(booking_form.faat_item3.checked == true){
        booking_form.faat_item3.value = c;
        sum += c;
        }
    else
        booking_form.faat_item3.value = 0;

    if(booking_form.osfa_item1.checked == true){
        booking_form.osfa_item1.value = d;
        sum += d;
        }
    else
        booking_form.osfa_item1.value = 0;

    if(booking_form.osfa_item2.checked == true){
        booking_form.osfa_item2.value = e;
        sum += e;
        }
    else
        booking_form.osfa_item2.value = 0;

    if(booking_form.osfa_item3.checked == true){
        booking_form.osfa_item3.value = f;
        sum += f;
        }
    else
        booking_form.osfa_item3.value = 0;

    if(booking_form.osfa_item4.checked == true){
        booking_form.osfa_item4.value = g;
        sum += g;
        }
    else
        booking_form.osfa_item4.value = 0;

    if(booking_form.osfa_item5.checked == true){
        booking_form.osfa_item5.value = h;
        sum += h;
        }
    else
        booking_form.osfa_item5.value = 0;

    return sum;
}

function sendTotal(){
    var total = calTotal();
    return total;
}

此代码计算结果很好，但我想将此计算结果直接作为金额发送到我的PayPal，以下是我的按钮代码：

<form name="_xclick" action="https://www.paypal.com/cgi-bin/webscr" method="post">
                        <input type="hidden" name="cmd" value="_xclick">
                        <input type="hidden" name="business" value="xyz@xyz.com">
                        <input type="hidden" name="currency_code" value="GBP">
                        <input type="hidden" name="item_name" value="MT1">
                        <input type="hidden" name="amount" value="sendTotal()">
                        <input type="image" src="http://www.paypalobjects.com/en_US/i/btn/btn_buynow_LG.gif" border="0" name="submit" alt="Make payments with PayPal - it's fast, free and secure!">
                    </form>

商家名称已更改，我尝试直接使用此sendTotal（），但PayPal提供格式错误，任何人都可以帮助我们如何将我的JS计算总数作为PayPal的数量发送给我们。

为您的总元素添加id属性，即id ='total'，并将其添加到您的javascript中。的document.getElementById（ '合计'）值= sendTotal（）; 这应该有用。

如何将我用JavaScript计算的自定义金额作为金额发送给PHP表单？
