layui之获取form表单的radio

form表单是这样的：

<div class="layui-form-item">
        <label class="layui-form-label">单选框</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获取radio如下：

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

同理form表单里面的checkbox也是一样的

<div class="layui-form-item">
        <label class="layui-form-label">复选框</label>
        <div class="layui-input-block">
            <input type="checkbox" name="like[write]" title="写作">
            <input type="checkbox" name="like[read]" title="阅读" checked value="阅读">
            <input type="checkbox" name="like[dai]" title="发呆">
        </div>
    </div>

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