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: ,
height: ,
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');
}, );
},
'onUploadError': function () {
setTimeout(function () {
$("#uploadofedit").dialog('close');
}, );
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');
}, );
},
'onUploadError': function () {
setTimeout(function () {
$("#uploadofedit").dialog('close');
}, );
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: ,
height: ,
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; }
}
