例子 演示

最好的方法是$('input[name="line"]:checked').val()

你也可以得到select text $('input[name="line"]:checked').text()

为单选按钮输入添加值属性和名称。确保所有输入都具有相同的name属性。

<div class="col-8 m-radio-inline">
    <label class="m-radio m-radio-filter">
        <input type="radio" name="line" value="1" checked> Value Text 1
    </label>
    <label class="m-radio m-radio-filter">
        <input type="radio" name="line" value="2"> Value Text 2
    </label>
    <label class="m-radio m-radio-filter">
        <input type="radio" name="line" value="3"> Value Text 3
    </label>
</div>

$('#checkbox_id').val();
$('#checkbox_id').is(":checked");
$('#checkbox_id:checked').val();

如果只期望选择一个子元素:

form.querySelector(":checked").value
