//工具栏的定义
<div class="btn-toolbar" data-role="editor-toolbar" data-target="#editor">
<div class="btn-group">
<a class="btn dropdown-toggle" data-toggle="dropdown" title="Font"><i class="icon-font"></i><b class="caret"></b></a>
<ul class="dropdown-menu">
</ul>
</div>
<div class="btn-group">
<a class="btn dropdown-toggle" data-toggle="dropdown" title="Font Size"><i class="icon-text-height"></i>&nbsp;<b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a data-edit="fontSize 5"><font size="5">Huge</font></a></li>
<li><a data-edit="fontSize 3"><font size="3">Normal</font></a></li>

<button class="btn" type="button">Add</button>
</div>
<a class="btn" data-edit="unlink" title="Remove Hyperlink"><i class="icon-cut"></i></a>
</div>

<div class="btn-group">
<a class="btn" title="Insert picture (or just drag & drop)" id="pictureBtn"><i class="icon-picture"></i></a>
<input type="file" data-role="magic-overlay" data-target="#pictureBtn" data-edit="insertImage" />

</div>
<input type="text" data-edit="inserttext" id="voiceBtn" x-webkit-speech="">
</div>
//文本输入区域
<div id="editor">
输入内容&hellip;
</div>

 

JS代码:

//初始化工具栏

 1 function initToolbarBootstrapBindings() {
 2 var fonts = ['Serif', 'Sans', 'Arial', 'Arial Black', 'Courier', 
 3 'Courier New', 'Comic Sans MS', 'Helvetica', 'Impact', 'Lucida Grande', 'Lucida Sans', 'Tahoma', 'Times',
 4 'Times New Roman', 'Verdana'],
 5 fontTarget = $('[title=Font]').siblings('.dropdown-menu');
 6 $.each(fonts, function (idx, fontName) {
 7 fontTarget.append($('<li><a data-edit="fontName ' + fontName +'" style="font-family:\''+ fontName +'\'">'+fontName + '</a></li>'));
 8 });
 9 $('a[title]').tooltip({container:'body'});
10 $('.dropdown-menu input').click(function() {return false;})
11 .change(function () {$(this).parent('.dropdown-menu').siblings('.dropdown-toggle').dropdown('toggle');})
12 .keydown('esc', function () {this.value='';$(this).change();});
13 
14 $('[data-role=magic-overlay]').each(function () { 
15 var overlay = $(this), target = $(overlay.data('target')); 
16 overlay.css('opacity', 0).css('position', 'absolute').offset(target.offset()).width(target.outerWidth()).height(target.outerHeight());
17 });
18 if ("onwebkitspeechchange" in document.createElement("input")) {
19 var editorOffset = $('#editor').offset();
20 $('#voiceBtn').css('position','absolute').offset({top: editorOffset.top, left: editorOffset.left+$('#editor').innerWidth()-35});
21 } else {
22 $('#voiceBtn').hide();
23 }
24 };
25 //错误提示
26 function showErrorAlert (reason, detail) {
27 var msg='';
28 if (reason==='unsupported-file-type') { msg = "Unsupported format " +detail; }
29 else {
30 console.log("error uploading file", reason, detail);
31 }
32 $('<div class="alert"> <button type="button" class="close" data-dismiss="alert">&times;</button>'+ 
33 '<strong>File upload error</strong> '+msg+' </div>').prependTo('#alerts');
34 };
35 initToolbarBootstrapBindings(); 
36 $('#editor').wysiwyg({ fileUploadError: showErrorAlert} );

 

二、自定义上传图片到服务器
主要修改bootstrap-wysiwyg.js中的一个方法

 1 var readFileIntoDataUrl = function (fileInfo) {
 2 //原有的方法
 3 // var loader = $.Deferred(),
 4 // fReader = new FileReader();
 5 // fReader.onload = function (e) {
 6 // loader.resolve(e.target.result);
 7 // };
 8 // fReader.onerror = loader.reject;
 9 // fReader.onprogress = loader.notify;
10 // fReader.readAsDataURL(fileInfo);
11 // return loader.promise();
12 
13 //自定义方法
14 var form = new FormData();
15 form.append("file", fileInfo);
16 var xhr = new XMLHttpRequest();
17 xhr.open("post", "/imgupload", false);//后台接收的方法,返回图片路径(全路径,不然页面不显示图片)
18 xhr.send(form);
19 return xhr.responseText;
20 };

 

后台接收的方法示例:

 1  public string UpLoadImgFile()
 2         {
 3             string szNewFilePath = "";
 4             if (Request.Files.Count>0)
 5             {
 6                 HttpPostedFileBase CoverImg = Request.Files[0];
 7                 Stream sr = CoverImg.InputStream;
 8                 FileRepositoryServiceClient client = new FileRepositoryServiceClient("http://uploadfile.qikan.com.cn/FileRepositoryService.svc", "MediaFile", "MediaFile");
 9                 
10                 client.CreateImageFile("MediaFile/" + Request.Files[0].FileName, sr, out szNewFilePath);
11                
12             }
13             return szNewFilePath = DragonUtility.IO.FileService.Client.FileRepositoryServiceClient.GetFilePath("Public/MediaFile", szNewFilePath);
14             //return RetActionJsonResult(SetSuccessResult(szNewFilePath));
15         }

 


三、传递参数

//在回台接收输入区域的内容使用jQuery
$("#editor").html();

结束:
这只是简单的使用示例。
还有很多更方便的使用技巧,希望有经验的朋友留言,共同学习。
