如何在Javascript中添加单选按钮组？

在我的代码中，我只显示了5个问题。我不知道如何为每个问题插入一组答案的单选按钮。帮忙

（我已经在java上完成了，但我无法将其转换为javascript。我是新手：|）

提前感谢

您可以通过DOM创建“输入”元素来创建单选选项

var ans1 = ["answer","answer","answer","answer"];
var ans2 = ["answer","answer","answer","answer"];
var ans3 = ["answer","answer","answer","answer"];
var ans4 = ["answer","answer","answer","answer"];
var ans5 = ["answer","answer","answer","answer"];
var questions = ["q1", "q2", "q3", "q4", "q5"];

通过设置type属性，可以进行无线电类型输入

var input = document.createElement("input");

您还可以设置输入的值

input.type = "radio";

这里有一把小提琴，让我们仔细看看：

我们可以将答案保存在二维数组中。这样我们就可以避免使用eval方法。第一个循环是关于问题，第二个循环是关于答案。 您可以尝试以下方法：

input.value = ans1[0];

var ans1=[“回答”、“回答”、“回答”、“回答”]；
var ans2=[“回答”、“回答”、“回答”、“回答”]；
var ans3=[“回答”、“回答”、“回答”、“回答”]；
var ans4=[“回答”、“回答”、“回答”、“回答”]；
var ans5=[“回答”、“回答”、“回答”、“回答”]；
风险值问题=[“第一季度”、“第二季度”、“第三季度”、“第四季度”、“第五季度]；
对于（var x=0；x

可能重复感谢！（它变成了一个复选框，但我解决了它）另一个问题，我如何才能选中单选按钮？对不起，更新了它。现在是广播箱。radio.name='answer'+i；需要是radio.name='answer'+数字；你的另一个问题不清楚。是否要使用Javascript获取所选的无线电值？抱歉。是，这样我就可以检查答案是否正确。document.querySelector（'input[name=“answer5”]：checked'）。该值将为您提供所选的单选值。

input.value = ans1[0];

var ans1 = ["answer","answer","answer","answer"];
var ans2 = ["answer","answer","answer","answer"];
var ans3 = ["answer","answer","answer","answer"];
var ans4 = ["answer","answer","answer","answer"];
var ans5 = ["answer","answer","answer","answer"];
var questions = ["q1", "q2", "q3", "q4", "q5"];

for (var x = 0; x < questions.length; x++)
{
    var number = x + 1;
    newp = document.createElement("p");
    newp.appendChild(document.createTextNode((number) + ". " + questions[x]));
    newp.appendChild(document.createElement('br'));
    var thisAnswers = eval('ans' + number);
    for(i in thisAnswers){
      var ans = thisAnswers[i];
      var label = document.createElement("label");
      var radio = document.createElement("input");
      radio.type  = "radio";
      radio.name  = 'answer' + number;
      radio.value = ans;
      label.appendChild(radio);
      label.appendChild(document.createTextNode(ans));
      newp.appendChild(label);
    }
    document.getElementById("q").appendChild(newp);
}
