一、表格中插入下拉框的情况

问题:表格遇到下拉框表单的情况,下拉框在表格中没办法显示出来,效果:

1、表格中下拉框被隐藏----方法1

这种方法解决了表格中下拉框被隐藏的状态了,但是显示并不是很美观,距离最下面的表格的下拉框展开之后会撑开表格的滚动条显示出来,可以看到截图效果:

这个办法只是简单是修改了一下css:

.layui-table-cell{overflow: visible;}

2、表格中下拉框被隐藏----方法2

第二种办法就是给下拉框加上这个属性:lay-ignore.忽略了美化效果自然就是普通的下拉框了,可以正常显示的,但是效果并不美观,你觉得不是你想要的,别急,我给它美观一下.

首先给select表单加了lay-ignore属性,这样子就变成普通的表单了.

再美化一下css改变效果:

 .table_select { width: 100%; height: 38px;
            line-height: 1.3;
            line-height: 38px \9;
            border-width: 1px;
            border-style: solid;
            border-color: #ccc;
            background-color: #fff;
            border-radius: 2px;
            padding-left:10px;
        }
        .table_select option{
            padding: 0 10px;
            line-height: 36px;
            white-space: nowrap;
            overflow: hidden;
            text-overflow: ellipsis;}
        /*修改表单默认文字颜色*/

        input, textarea,select {
            color: #999; /* 光标的颜色*/
            text-shadow: 0px 0px 0px #999; /* 文本颜色 */
            -webkit-text-fill-color: transparent; }
        input::-webkit-input-placeholder,select::-webkit-input-placeholder { color: rgb(60, 0, 248); /* 改变placeholder文本颜色 */ text-shadow: none; -webkit-text-fill-color: initial; }

效果如下:

大家可以看到效果了,只是默认效果跟原来的差不多一样,只是点击效果内容有点丑,也勉强接受..

3、表格中下拉框被隐藏----方法3

参考:@FIRSTK 的bootstrap下拉菜单组件 https://fly.layui.com/jie/20494/

由于这个版本当时是layui-v2.24版本的,现在插件已经到2.4.5了,做的时候同步就有点麻烦,所以要切换成旧版本的.

bootstrap下拉菜单效果如果,需要的也可以用:

 <div class="layui-btn-dropdown">
        <button type="button" class="layui-btn layui-btn-sm" data-toggle="dropdown">操作 <span class="layui-icon" style="font-size: 14px"></span></button>
        <ul class="layui-dropdown-menu">
            <li><a href="#" onclick="alert(2)">功能</a></li>
            <li><a href="#">另一个功能</a></li>
            <li><a href="#">其他</a></li>
            <li class="divider"></li><!--分割线-->
            <li><a href="#">分离的链接</a></li>
        </ul>
    </div>

Copy after login

二.弹窗中下拉框显示被隐藏1.当弹窗高度不够的时候,这个就有问题了

解决办法:

①修改全局css

.layui-layer-page .layui-layer-content { overflow: visible !important; }

Copy after login

②修改当前的弹窗的css,给弹窗加个id,比如#layer_pop;这样不影响其他的弹窗效果.

#layer_pop.layui-layer-content { overflow: visible !important; }

Copy after login

layer.open({
            id:&#39;layer_pop&#39;,
            type: 1,
            title: &#39;点击弹窗&#39;,
            area: &#39;640px&#39;,
            shadeClose: true, //点击遮罩关闭
            content: $(&#39;#clickBtnView&#39;),
            btnAlign: &#39;c&#39;
            , zIndex: 198910160
            , btn: [&#39;确定&#39;, &#39;取消&#39;]
            , yes: function (index, layero) {
                //按钮【按钮一】的回调

                layer.close(index);
            }
            , btn2: function (index, layero) {
                //按钮【按钮二】的回调
                if (confirm(&#39;确定要关闭么&#39;)) { //只有当点击confirm框的确定时，该层才会关闭
                    layer.close(index)
                }
                // return false //开启该代码可禁止点击该按钮关闭
            }
            , cancel: function (index, layero) {
                //右上角关闭回调

                //return false 开启该代码可禁止点击该按钮关闭
            }
        });

Copy after login
