如何为不同的“正确”答案分配要被总结的个人价值？
如何为不同的“正确”答案分配要被总结的个人价值？
提问于 2020-08-18 18:47:32
在一个简单的测试中，一个人如何分配一个唯一的值来增加，所以一个问题可能比其他的问题加权得更多，而不是在每个正确答案的分数上加1？首先尝试将测试分开，这个问题可能更容易解决，但我不确定如何进行。

好的，这是另一次对整件事的重写。:D
我重组了你的HTML标记。它太冗长，太重复了。现在，我从对象questions生成所有内容。在它中，你会发现问题本身与所有可能的答案选项(可以是任意数量的答案)。答案数组(每个问题对象中的属性a )具有以下格式：[["possible answer value", [test1score,test2score,test3score]], ["next possible answer",[...]], ...]。根据选择的答案，其中一个点数组将被添加到结果数组res中。然后，总总和将显示在三个.res跨度中。
const questions=[ // questions, answers with their associated points:
{q:"History of Stroke", a:[["Yes",[10,10, 0]],["No" , [ 0, 0, 0]]]},
{q:"Age", a:[[">84",[20,20, 0]],["<84", [ 0, 0, 0]]]},
{q:"Female", a:[["Yes",[10, 0,30]],["No" , [ 0, 0, 0]]]},
{q:"History of diabetes mellitus", a:[["Yes",[20,50, 0]],["No" , [ 0, 0, 0]]]},
{q:"History of congestive heart failure",a:[["Yes",[30, 0,50]],["No" , [ 0, 0, 0]]]},
{q:"History of hypertension", a:[["Yes",[30, 0, 0]],["No" , [ 0, 0, 0]]]},
{q:"Body mass index", a:[["<23",[ 0, 0, 0]],["23...28",[20,20,30]],[">28" ,[50,60,40]]]},
{q:"Proteinuria", a:[["Yes",[10, 0, 0]],["No", [ 0, 0, 0]]]},
{q:"EGFR less Than 45 or end-stage renal desease",
a:[["Yes",[0, 0, 0]],["No", [ 0, 0, 0]]]}
];
const frm =document.querySelector("form");
// create questions block first:
frm.innerHTML=questions.map(q=>{
let nam=q.q.toLowerCase().replace(/ /g,"").substr(0,12)
return `<p style="color:green;font-size:20px">${q.q}</p>
<ul style="margin-top: 3pt">${q.a.map(([a])=>`<label><input type="radio" name="${nam}" value="${a}">${a}</label>`).join('<br>\n')}</ul>`;
}).join('\n')+frm.innerHTML;
let spans=[...document.querySelectorAll('span.res')];
document.querySelector("input[type=reset]").onclick=ev=>spans.forEach(sp=>sp.textContent="");
frm.onchange=ev=>{
let res=[0,0,0], uls=document.querySelectorAll('form ul');
questions.forEach((qo,i)=>{ var a;
if (a=uls[i].querySelector("input:checked")){ // only if an answer has been chosen
let pts=qo.a.find(([el])=>el==a.value)[1] // get array with points for all tests
res.forEach((r,i)=>res[i]+=pts[i]); // add points to res-array
}
});
res.forEach((r,i)=>spans[i].textContent=r)
