前台頁面代碼：

<div id="lj" class="page-show">
                                    <label style="margin-top: 6px">
                                        <h4>内頁展示：</h4>
                                    </label><br>

                                        <!--詳情頁圖檔上傳區域，内容編輯（富文本編輯）-->
                                        <div style="position:relative; z-index:0;margin-left: 40px" th:utext="${WxMainDetail.imageUrl}" name="editor" id="editor">
                                        </div>
                                    </div>


                                    <!--頁面連結-->
                                    <div id="links-jump" class="ps">
                                        <hr>
                                        <label style="margin-left: 30px">連結到頁面</label><br>
                                        <label style="margin-left: 40px">連結跳轉</label>
                                        <input class="link" name="link" type="text" placeholder="請輸傳入連結接位址">
                                    </div>
                                </div>
           

注意這裡

<div style="position:relative; z-index:0;margin-left: 40px" th:utext="${WxMainDetail.imageUrl}" name="editor" id="editor">
                                        </div>
