推荐答案

如果我们喜欢下面的代码，则可以将整个单选按钮获取为innerHTML，并且可以为单选按钮应用样式. />

If we do like the below code we can get the total radio button as innerHTML and we can apply styles for the radiobutton..

if(document.getElementById("rbId").checked)
{
    alert(document.getElementById("rbId").parentNode.innerHTML);
}

(或)

如果我们只想查找单选按钮的TEXT，则可以得到如下所示:

(or)

If we want to find only the TEXT of radiobutton means we can get like this:

alert(document.getElementById("rbId").parentNode.childNodes[1].innerHTML);

通过这样做，我们可以直接获取单选按钮的文本

By doing this we can directly get the text of radiobutton

诸如getElementById之类的东西可以为您提供帮助.

我认为您需要使用getElementsByTagName(''label'').这可能会有所帮助.
