Question

我正在创造一个冗长的形式。如果您符合条件（勾选标记），则有5个不同的部分供您标记。总共可能有50个问题。每个部分具有不同的重量/点（第1部分各1分，第2部分各3分）。如何显示总分并且我的脚本计算看起来不错？对不起，我对此很新。没有包括整个表格，因为它很长。

Answer 1

老实说，当前代码接近此方式的方式很容易通过拼写错误或遗漏而出错，同时也很难维护。

我的主要建议是利用包含运行总计的分数为id的div，让每个复选框调用一个函数，将其值作为调整得分的innerHTML的参数，例如： HTML：
Your Risk is <span id='risklevel'>Low</span> (<span id='score'>0</span>)
<input type='checkbox' onchange='updateScore(this,3);' />

JS：

function updateScore(ele,val){
    var score = document.getElementById('score');
    var riskLevel = document.getElementById('risklevel');

    var curScore = parseFloat(score.innerHTML);
    curScore += (ele.checked ? val : -val);
    score.innerHTML = curScore;

    if(curScore <= 1){
        riskLevel.innerHTML = "Low";
    }else if(curScore <= 2){
        riskLevel.innerHTML = "Moderate";
    }else if(curScore <= 4){
        riskLevel.innerHTML = "High";
    }else{
        riskLevel.innerHTML = "Very High";
    }
}

或
如果你想坚持使用一次性计算方法......

使用本地dom-searchable方式标记复选框（我建议使用数据前缀的类 - （例如： data-riskFactorSet ）），为每个复选框赋予data- *属性（如as data-riskvalue ）并让你的js迭代所有checkboxen，结合data- *属性的int / float值。

注意：因为它是一个不太受欢迎的构造...... (ele.checked ? val : -val)使用三元运算符。可以把它想象成一个内联的 if-then-else 语句，并且规定true和false部分的返回类型必须相同。它的工作原理如下：
test ? ifTrue : ifFalse
