Question

我无法获得所选的单选按钮值。基本上，我在我的Html页面中遇到问题，我想打印选定的单选按钮值。我想在特定div中的同一页面上获取值。下面是我的代码。提前谢谢。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Test</title>

<script type="text/JavaScript">
     function myFunction()
    {
        var input = (document.getElementById('shirt').checked)|| (document.getElementById('trouser').checked) || (document.getElementById('tshirt').checked)|| (document.getElementById('suit').checked);
        var div = document.getElementById('divID');
        div.innerHTML = div.innerHTML + input.value;
    }
    </script>
</head>
<body>
<form action="#" method="post" id="demoForm">
    <div class="controls option block-1">

Answer 1

您可以将querySelector用于javascript -

<script type="text/JavaScript">
 function myFunction()
{
    var input = document.querySelector('input[name="garments"]:checked').value;
    var div = document.getElementById('divID');
    div.innerHTML = div.innerHTML + input+"<br>";
}
</script>

Answer 2

要获取所选的单选按钮值，您可以使用jQuery： $('[name=garments]:checked').val()

无法在javascript中获取div上的单选按钮值
