ASP.NET MVC4实现TinyMCE 4.0.20自定义上传功能
tinymce 插件不提供免费的本地图片上传功能，所以自己将uploadify这个上传插件整合到tinymce，实现本地上传，还用到了jquery.ui插件，先展示全部的代码
@model TinyMCEUpload.Models.TinyMCEModels <script type="text/javascript"> $(document).ready(function () { var tinymceEditor; tinymce.init({ selector: "textarea#content", auto_focus: "content", language: "zh_CN", theme: "modern", plugins: [ "advlist autolink lists link image charmap preview", "searchreplace visualblocks fullscreen", "insertdatetime media table contextmenu paste", "emoticons textcolor" ], toolbar1: "undo redo | styleselect | fontselect | fontsizeselect | bold italic underline strikethrough | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent", toolbar2: "fullscreen preview | forecolor backcolor emoticons | table | link image media | mybutton", setup: function (editor) { editor.addButton('mybutton', { text: '上传图片', icon: false, onclick: function () { tinymceEditor = editor; $("#uploadofedit").dialog({ modal: true, resizable: false, width: 400, height: 200, dialogClass: "mceuploadify" }); } }); }, //TinyMCE 会将所有的 font 元素转换成 span 元素 convert_fonts_to_spans: true, //换行符会被转换成 br 元素 convert_newlines_to_brs: false, //在换行处 TinyMCE 会用 BR 元素而不是插入段落 force_br_newlines: false, //当返回或进入 Mozilla/Firefox 时，这个选项可以打开/关闭段落的建立 force_p_newlines: false, //这个选项控制是否将换行符从输出的 HTML 中去除。选项默认打开，因为许多服务端系统将换行转换成 <br />，因为文本是在无格式的 textarea 中输入的。使用这个选项可以让所有内容在同一行。 remove_linebreaks: false, //不能把这个设置去掉，不然图片路径会出错 relative_urls: false, //不允许拖动大小 resize: false, font_formats: "宋体=宋体;黑体=黑体;仿宋=仿宋;楷体=楷体;隶书=隶书;幼圆=幼圆;Arial=arial,helvetica,sans-serif;Comic Sans MS=comic sans ms,sans-serif;Courier New=courier new,courier;Tahoma=tahoma,arial,helvetica,sans-serif;Times New Roman=times new roman,times;Verdana=verdana,geneva;Webdings=webdings;Wingdings=wingdings,zapf dingbats", fontsize_formats: "8pt 10pt 12pt 14pt 18pt 24pt 36pt" }); $("#tinymceuploadify").uploadify({ 'swf': '../../uploadify/uploadify.swf', 'buttonText': '上传本地图片', 'uploader': '/Home/Upload', 'auto': true, 'method': 'post', 'multi': false, 'onUploadSuccess': function (event, data, flag) { var img = "<img src='../../File/" + data + "'>"; tinymceEditor.insertContent(img); setTimeout(function () { $("#uploadofedit").dialog('close'); }, 1000); }, 'onUploadError': function () { setTimeout(function () { $("#uploadofedit").dialog('close'); }, 1000); alert("上传失败"); } }); }); </script> <div> <form method="post" action="/Home/Test"> <textarea id="content" name="content" style="width: 100%; height: 600px;"></textarea> <input type="submit" value="提交" /> </form> </div> <div id='uploadofedit' style="display: none;"> <input type='file' name='tinymceuploadify' id='tinymceuploadify' /> <label>只能上传单张10M以下的 png、jpg、gif 格式的图片</label> </div>
接下来分步骤来分析
1 先实现在tinymce插件上添加自定义按钮
toolbar2: " mybutton", setup: function (editor) { editor.addButton('mybutton', { text: '上传图片', icon: false, onclick: function () { }); } }); },
2.初始化uploadify插件
$("#tinymceuploadify").uploadify({ 'swf': '../../uploadify/uploadify.swf', 'buttonText': '上传本地图片', 'uploader': '/Home/Upload', 'auto': true, 'method': 'post', 'multi': false, 'onUploadSuccess': function (event, data, flag) { var img = "<img src='../../File/" + data + "'>"; tinymceEditor.insertContent(img); setTimeout(function () { $("#uploadofedit").dialog('close'); }, 1000); }, 'onUploadError': function () { setTimeout(function () { $("#uploadofedit").dialog('close'); }, 1000); alert("上传失败"); } });
3.在点击自定义按钮后启用jquery-ui的dialog插件调出上传对话框
setup: function (editor) { editor.addButton('mybutton', { text: '上传图片', icon: false, onclick: function () { tinymceEditor = editor; $("#uploadofedit").dialog({ modal: true, resizable: false, width: 400, height: 200, dialogClass: "mceuploadify" }); } }); }
至此前台部分OK了，接下来是后台
1.后台接收用户上传的图片
[HttpPost] public ContentResult Upload(HttpPostedFileBase Filedata) { string result = string.Empty; string folder = Server.MapPath("~/File/"); string time = DateTime.Now.ToString("yyyyMMddHHmmssff");//获取时间 string extension = System.IO.Path.GetExtension(Filedata.FileName);//获取扩展名 string newFileName = time + extension;//重组成新的文件名 if (!System.IO.Directory.Exists(folder)) System.IO.Directory.CreateDirectory(folder); Filedata.SaveAs(folder + "\\" + newFileName); return Content(newFileName); }
2.接收tinymce插件的内容（我这里简单的用记事本来替代数据库），然后再从记事本中把内容读出来呈现到另一个页面上
/// <summary> /// 接收tinymce插件的内容 /// </summary> /// <param name="model"></param> /// <returns></returns> public ActionResult Test(TinyMCEModels model) { var path = Server.MapPath("~/File/123.txt"); var str = System.IO.File.ReadAllText(path); if (System.IO.File.Exists(path)) { System.IO.File.Delete(path); } System.IO.File.WriteAllText(path, model.content); return RedirectToAction("Show"); } /// <summary> /// 将记事本的内容读出来，重新加载到页面上 /// </summary> /// <returns></returns> public ActionResult Show() { var str = System.IO.File.ReadAllText(Server.MapPath("~/File/123.txt")); ViewBag.str = str.Trim(); return View(); }
因为在mvc4中为了防止脚本攻击，默认是不允许有html标记的内容传到后台的，所以我建立了一个TinyMCEModels，在content属性上加上AllowHtml标记（在System.Web.Mvc命名空间下），这样就行了
public class TinyMCEModels { [AllowHtml] public string content { get; set; } }
