我无法获取选定的单选按钮值。基本上，我在我的 Html 页面中遇到了问题，我想在其中打印选定的单选按钮值。 我想在特定 div 的同一页面上获取值。下面是我的代码。 提前致谢。
<!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">
<div class="col-sm-3 col-md-3 prod-left-text">

<p class="subtitle">Please choose your garments.</p>
</div>
<div class="col-sm-9 col-md-9">
<div class="col-md-3 col-sm-6 col-xs-12 option-value form-group">

</div>

</div>
<p><button type="button" value="submit">Get Value of Selected</button></p>
<!-- Div where i want to put the selected radio valur -->
<div id="divID"></div>

</form>
</body>

最佳答案
您可以使用 querySelector for 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>
