Question

我正在学习HTML的入门课程，并且一直在努力通过使用java的页面找到我的错误。我确信我犯了一个简单的错误，但我没有看到它

以下是我正在使用的代码的小提琴： https://jsfiddle.net/Terranova1340/ctc66nmu/2/

    }
    processForm();
}

function processForm(){

    var bPrice = 0;
    var aPrice = 0;
    var oPrice = 0;
    var tPrice = 0;

    if (document.getElementById("selModel").value =="civic")
    {
            bPrice = 17355.89;

         if (document.getElementById("optAccess1").checked == true)

         {
            oPrice = 385.67;
         }
         if (document.getElementById("custFin").checked == true)
        {
            oPrice = 400.00;
        }
    }



    //calculate total

    tPrice = bPrice+aPrice+oPrice;
    document.getElementById("basePrice").value = "$" + formatCurrency(bPrice).toString();
    document.getElementById("accessPrice").value = "$" + formatCurrency(aPrice).toString();
    document.getElementById("extPrice").value = "$" + formatCurrency(oPrice).toString();
    document.getElementById("estPrice").value = "$" + formatCurrency(tPrice).toString();

    }

    function formatCurrency(num){
    num = isNaN(num) || num === ''|| num === null ? 0.00 : num;
    return parseFloat(num).toFixed(2);
    }

我的问题是基本价格到估计总价格字段不会填充。

提前致谢！

您使用了错误的id's，更改为optAccess1，optAccess2，optAccess3此处

    <td><label class='checkbox'><input type="checkbox" id="optAccess1"value="stereoSys" onchange="processForm()"> Stereo System<br>
    <label class='checkbox'><input type="checkbox" id="optAccess2" value="leatherInt" onchange="processForm()"> Leather Interiors<br>
    <label class='checkbox'><input type="checkbox" id="optAccess3" value="gpsSys" onchange="processForm()"> GPS System<br><br>
    </td>
