Tinymce 编辑器添加自定义图片管理插件

在使用Tinymce的过程中需要用到图片上传功能,而提供的上传插件在上传文件后是给了一个连接地址,就想用户需要什么图片,不能用最直观的方式表现出来么!

虽然官网上也有一个文件管理的插件moxiemanager,可奈何他是收费的!https://www.tiny.cloud/docs/plugins/moxiemanager/

然后就打算自己弄一个,其实实现效果起来很简单,就只是做了一个类型相册管理的功能,然后在点击图片的时候,将图片的地址信息插入到编辑器里就行了,由于后台用的是layui

的框架,所以界面也就用了layui来实现,这里我只弄了上传,删除功能,也可自己添加检索等功能,实现效果如下

图片管理

1 、添加插件

我们需要在tinymce的 Plugins  目录下新建一个filemanager文件夹,并添加一个名为plugin.min.js ,其中editor传参后再图片管理页面通过

var editor = top.tinymce.activeEditor.windowManager.getParams().editor; 获取编辑器对象

tinymce.PluginManager.add("filemanager", function (editor, url) {
    editor.addButton("filemanager", {
        title: "图片管理",
        icon: 'image',
        onclick: function () {
            editor.windowManager.open({
                title: "图片管理",
                url:  "Editor",//图片管理地址
                width: window.innerWidth * 0.9,
                height: window.innerHeight * 0.8
            }, {
                    editor: editor //用于在点击图片时将调用,以便将图片信息插入编辑器中
            })
        }
    })
});

2. 相册功能实现

文件夹管理实体类

public class FileManagerDirectoryEntity : BaseEntity
    {
        /// <summary>
        /// 父级Id
        /// </summary>
        public int ParentId { get; set; }

        /// <summary>
        /// 文件夹名称
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// 路径
        /// </summary>
        public string FullPath { get; set; }

        /// <summary>
        /// 子文件数量
        /// </summary>
        public int ChildrenCount { get; set; }
    }

文件管理实体类

public class FileManagerDirectoryEntity : BaseEntity
    {
        /// <summary>
        /// 父级Id
        /// </summary>
        public int ParentId { get; set; }

        /// <summary>
        /// 文件夹名称
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// 路径
        /// </summary>
        public string FullPath { get; set; }

        /// <summary>
        /// 子文件数量
        /// </summary>
        public int ChildrenCount { get; set; }
    }

相册功能具体实现controller

public class FileManagerController : Controller
    {

        #region Core
        private readonly IRepository<FileManagerDirectoryEntity> _fileManagerDirectoryRepository;
        private readonly IRepository<FileManagerFilesEntity> _fileManagerFilesRepository;
        private const string smallImage = "_small";

        public FileManagerController(
             IRepository<FileManagerDirectoryEntity> fileManagerDirectoryRepository,
             IRepository<FileManagerFilesEntity> fileManagerFilesRepository
            )
        {
            this._fileManagerDirectoryRepository = fileManagerDirectoryRepository;
            this._fileManagerFilesRepository = fileManagerFilesRepository;
        }

        #endregion

3. 将选中图片插入编辑器

在图片列表的页面中,我们只需要在点击图片的事件中调用Tinymce编辑器的插入方法即可,以下为插入图片的代码

<script>
        //获取tinymce编辑器
        var editor = top.tinymce.activeEditor.windowManager.getParams().editor;

        layui.use(['upload'], function () {
            var upload = layui.upload;
            var dirId = $("#dirId").val() == "" ? 0 : $("#dirId").val();
            upload.render({ //允许上传的文件后缀
                elem: '#upload-img-btn'
                , url: 'UploadImage?dirId=' + dirId
                , accept: 'file' //普通文件
                , multiple: true
                , size: 1024 * 2 //限制文件大小,单位 KB
                , exts: 'jpg|jpeg|png|gif' //只允许上传压缩文件
                , done: function (res) {
                    if (res.code == 0) {
                        window.location.reload();
                    }
                }
            });

            //删除图片
            $("#delete-img-btn").click(function () {
                var checkeds = [];
                $("input[name='file-id']:checkbox").each(function () {
                    if (true == $(this).is(':checked')) {
                        checkeds.push({
                            id: $(this).data('id'),
                            type: $(this).data('type')
                        });
                    }
                });
                if (checkeds.length == 0) {
                    layer.alert('请先选择需要删除的文件!');
                }
                else {
                    layer.confirm('删除后将无法恢复,请确认是否要删除所选文件?', {
                        btn: ['确定删除', '我在想想'] //按钮
                    }, function () {
                        $.ajax({
                            type: 'post',
                            url: 'CheckedFilesDelete',
                            data: { checkeds : checkeds },
                            success: function (result) {
                                if (result.code == 0) {
                                    window.location.reload();
                                }
                                else {
                                    showMsg(result.msg);
                                }
                            }
                        })
                    }, function () {
                    });
                }
            })
        })

        //添加图片至编辑器
        $(".file-img").click(function () {
            var url = $(this).data("url"),
                title = $(this).data("title");

            //添加确认
            layer.confirm('是否需要添加此图片?', {
                btn: ['确认添加', '我在想想'] //按钮
            }, function () {
                editor.execCommand('mceInsertContent', false, '<img alt="' + title + '" src="' + url + '"/>');
                editor.windowManager.close();
            }, function () {});
        })
        
    </script>
