Layear的代码：

function tankuang() {
        layer.open({
            type: 2,
            title: false,
            area: ['800px', '400px'],
            closeBtn: 0,
            shadeClose: true,
            skin: 'yourclass',
            content: '@Url.Action("PartialView", "UEditor")',
        });
    }

 Ueditor代码：

var editor = new baidu.editor.ui.Editor({
        UEDITOR_HOME_URL: '/Scripts/ueditor/',//配置编辑器路径
        iframeCssUrl: '/Scripts/ueditor/themes/iframe.css',//样式路径
        initialContent: '',//初始化编辑器内容
        autoHeightEnabled: true,//高度自动增长
        minFrameHeight: 500,//最小高度
        autoFloatEnabled: true,


        initialFrameWidth: 784,
        initialFrameHeight: 400

    });
    editor.render('editor');

 获取按钮中的值：

function getValue(val) {
        btnValue = val;
    }

<input type="button" name="zhishi" id="zhishi" value="基础讲解" onclick="tankuang(); getValue(this.value)" />

 用div来显示图片，textarea的值存入数据库

<div>
                    <div id="knowledgeTitle" style="display:none;float:left;width:70px;">知识点标题</div>
                    <input type="text" name="titleValue" value="" id="txtContent" hidden="hidden" />
                </div>

                <div>
                    <textarea id="divOneyc" name="editorOne" hidden="hidden" rows="10" cols="40"></textarea>
                </div>

                <div id="knowledgeContent" style="display:none;float:left;width:70px;">知识点标题</div>
                <div id="divOne" name="editorOne" style="width: 700px; height: 400px; border: black 1px solid; font-size:small; line-height:1; overflow:auto;"
                     hidden="hidden">
                </div>

 同步值

//同步和Index的内容
    function getPlainTxt() {
        var arr = [];
        arr.push(UE.getEditor('editor').getPlainTxt());
        localStorage.removeItem("code");

        localStorage.setItem("code", arr.join('\n'));
        var data = localStorage.getItem("code");
        if (data && data.length > 0) {
            parent.mes = arr.join('\n');
            parent.document.getElementById('divOne').innerHTML = data;
            //给textarea获取值
            parent.document.getElementById('divOneyc').innerHTML = data;

        }
        parent.layer.closeAll();
        
        parent.document.getElementById("knowledgeContent").style.display = "block";

        parent.document.getElementById("divOne").style.display = "block";
        //让textarea永远隐藏
        parent.document.getElementById("divOneyc").style.display = "none";

        //同步标题的内容
      
        var title = document.getElementById("title").value;

        localStorage.removeItem("valuetxt");
        localStorage.setItem("valuetxt", title);
        var txtValue = localStorage.getItem("valuetxt");
        if (txtValue && txtValue.length > 0) {
            parent.document.getElementById("knowledgeTitle").style.display = "block";
            parent.document.getElementById("txtContent").value = txtValue;
        }

        parent.document.getElementById("txtContent").style.display = "block";
    }

<div>
        知识点标题
        <input type="text" class="biaoti" name="biaoti" value="" id="title" />
    </div>

    <div>
        基本内容
        <textarea id="editor" name="editor"></textarea>
    </div
