css

<div class="layui-input-inline" style="width:1100px;"><div class="noticeContent"><textarea id="Introduce1" name="处分结果" class="form-control" style="z-index:19991015"></textarea></div>
</div>

引用插件

<script src="~/Areas/JL_jilu/ckeditor/ckeditor.js"></script>

js

var CKEDITOR;
var Introduce1;
$(".layui-layer-shade").css("z-index", "0");$(".layui-layer").css("z-index", "1");if (CKEDITOR.instances['Introduce1']) {CKEDITOR.instances['Introduce1'].destroy();}CKEDITOR.replace('Introduce1', {language: 'zh-cn',});CKEDITOR.instances.Introduce1.getData("");

找到存放ckeditor插件里面的config.js插件，添加上：

config.baseFloatZIndex = 199910156;

这样在layui模态框里面富文本的大小字体等下拉就出来了。
