我还想将单选按钮值显示为图像。.例如，当用户选择“男性”时，“男性”图片显示

最佳答案
在代码中包含jquery，输入中提到了snot属性ID。另外，您的代码中也没有ID（例如test）。
您也不需要再次重复选择器，只需使用$(this)
请尝试以下代码段。
function myFunction() {
var radioButtons =["gender","occupation","loan"];
for( var x = 0; x < radioButtons.length; x ++) {
if ($('input[name = "'+radioButtons[x]+'"]:checked').val()) {
alert("Value is " + $(this).val());
}
}
