I'd wrap them all in a container with a div just for easier selecting, and then you can use:
我将它们全部包装在一个带有 div 的容器中，以便于选择，然后您可以使用：
if($('#wrapperID input:checked').length > 0) {
'at least one is checked
}

try this
尝试这个
$('form').submit(function(e) {
if($("input:checked").length == 0){
alert('please checked atleast one');
}
});?
