Question

这个剧本有些不起作用。我需要在检查一个单选按钮时以总价格添加金额。这样做很好，但如果我检查不同的单选按钮，它会广告所有这些按钮。如果我总计= 100 $;和button1 = 10 $，button2 = 10 $，button3 = 10 $ 如果我检查所有3 ...我会得到总数= 130 $而不是110 $

function calculateTotal(payment)
{
    var check=document.getElementById("check").value;
    var city = document.getElementsByName('loc');
    var value= payment.value;
    var total= document.getElementById("totl").value;
    var tcharge;
    var pvcharge=document.getElementById("ch").value;
    if(value==0 && check==0)
    return;

    if(value==0 && check==1)
    {
        total= parseFloat(parseFloat(total)-parseFloat(pvcharge)).toFixed(2);
        tcharge=0;
    }else
    {
    if(total>=200)
    return;
    if(value=='online' || value =='transfer_bancar' || value=='cash' || value == 'la_sediul_nostru')
        {
            if(city[0].checked)
            {
            total= parseFloat(parseFloat(total)+15.0).toFixed(2);
            tcharge=15.00;
            }
            else
            if(city[1].checked)
            {
            total= parseFloat(parseFloat(total)+30.0).toFixed(2);
            tcharge=30.00;
            }
        }
        else
        if(value='la_expeditor')
        {

        if(city[0].checked)
            {
            total= parseFloat(parseFloat(total)+30.0).toFixed(2);
            tcharge=30.00;
            }
            else
            if(city[1].checked)
            {
            total= parseFloat(parseFloat(total)+60.0).toFixed(2);
            tcharge=60.00;
            }
        }
        }

        document.getElementById("tot").innerHTML=total+" LEI";
        document.getElementById("totl").value=total;
        document.getElementById("amt").value=total;
        document.getElementById("tcharge").innerHTML=tcharge+" LEI";
        document.getElementById("check").value=1;
        document.getElementById("ch").value=tcharge;

}

和php

if($Tott<200)
if(isset($_POST['loc']))
{
$tcharges=$_POST['loc'];

        if(isset($_POST['payment']))
        {
            $payment=$_POST['payment'];
            if($payment!=0)
          if($payment=='online' || $payment =='transfer_bancar' || $payment=='cash' || $payment == 'la_sediul_nostru')
            {
                if($tcharges=='in')
                    $Tott+=15;
                    else
                    $Tott+=30;
            }else
            if($payment=='la_expeditor') 
            {
                if($tcharges=='in')
                    $Tott+=30;
                    else
                    $Tott+=60;

            }


        }
}

Answer 1

每次，您都在操作上一次计算的总和。

违规行：

    var total= document.getElementById("totl").value;

相反，将其更改为原始的干净值。

如果选中了单选框，则向总计添加值
