所以我有一个3个问题＆＃34;你在哪个专业测验＆＃34; ...在选择并提交了文本，广播和选择之后，结果显示在他们旁边。文本和选择但不是收音机。选择显示我是否有无线电，if ((php.checked==false) && (asp.checked==false) && (js.checked==false)){rad.setAttribute("style", "display:inline");} ...我的设置现在如何显示文本，但收音机并选择不。此外，我需要一个包含解决方案的数组，一旦答案提交，它就会随机显示一个解决方案，例如＆＃34;你是一个战士！＆＃34;。这是.PHP扩展。继承我的代码：

答案 0 :(得分：0)
就像这样，您的单选按钮将始终具有值＆＃39; A＆＃39;，＆＃39; B＆＃39;或者＆＃39; C＆＃39;，它只是您在HTML中定义它们的方式。
应使用＆＃39; .checked＆＃39;检查无线电按钮是否有效。财产而不是价值。
我对您的代码所做的更改是：
我更新了你的if
if (php.checked) {
document.getElementById("radMess").innerHTML = "Healer";
rad.setAttribute("style", "display:inline");
chk = false;
}
if (asp.checked) {
document.getElementById("radMess").innerHTML = "Dark";
rad.setAttribute("style", "display:inline");
chk = false;
}
if (js.checked) {
document.getElementById("radMess").innerHTML = "One with the Elements";
rad.setAttribute("style", "display:inline");
chk = false;
}

所以......我不得不重命名一切，因为我一直感到困惑。不要只是将其打开或完全复制......你的老师可能会知道你没有这样做。
