form表單是這樣的：

<div class="layui-form-item">
        <label class="layui-form-label">單選框</label>
        <div class="layui-input-block">
            <input type="radio" name="sex" value="男" title="男">
            <input type="radio" name="sex" value="女" title="女" checked
 
>
        </div>
    </div>

用jquery獲取radio如下：

var value = $("input[name='sex']:checked").val();
console.log(value);

同理form表單裡面的checkbox也是一樣的

<div class="layui-form-item">
        <label class="layui-form-label">複選框</label>
        <div class="layui-input-block"
 
>
            <input type="checkbox" name="like[write]" title="寫作">
            <input type="checkbox" name="like[read]" title="閱讀" checked value="閱讀">
            <input type="checkbox" name="like[dai]" title="發呆">
        </div>
    </div>

var check = $("input[name='like[read]']:checked").attr("title");
console.log(check);
