使用其实很简单的，倒入bootstrap相关CSS，JS，jQuery，还有bootstrap-wysiwyg的JS，如下：

<link href="bootstrap-combined.no-icons.min.css" rel="stylesheet">
<link href="bootstrap-responsive.min.css" rel="stylesheet">
<link href="http://netdna.bootstrapcdn.com/font-awesome/3.0.2/css/font-awesome.css" rel="stylesheet">
<link rel="stylesheet" href="index.css" type="text/css"> </link>
<script src="jquery1.9.1.min.js" type="text/javascript"></script>
<script src="bootstrap.min.js"></script>
<script src="bootstrap-wysiwyg.js" type="text/javascript"></script>
<script src="external/jquery.hotkeys.js" type="text/javascript"></script>

定义相关菜单项目属性和方法：

function initToolbarBootstrapBindings() {
  var fonts = ['Serif', 'Sans', 'Arial', 'Arial Black', 'Courier', 
   'Courier New', 'Comic Sans MS', 'Helvetica', 'Impact', 'Lucida Grande', 'Lucida Sans', 'Tahoma', 'Times',
   'Times New Roman', 'Verdana'],
   fontTarget = $('[title=Font]').siblings('.dropdown-menu');
  $.each(fonts, function (idx, fontName) {
   fontTarget.append($('<li><a data-edit="fontName ' + fontName +'" style="font-family:\''+ fontName +'\'">'+fontName + '</a></li>'));
  });
  $('a[title]').tooltip({container:'body'});
  $('.dropdown-menu input').click(function() {return false;})
  .change(function () {$(this).parent('.dropdown-menu').siblings('.dropdown-toggle').dropdown('toggle');})
  .keydown('esc', function () {this.value='';$(this).change();});

  $('[data-role=magic-overlay]').each(function () { 
  var overlay = $(this), target = $(overlay.data('target')); 
  overlay.css('opacity', 0).css('position', 'absolute').offset(target.offset()).width(target.outerWidth()).height(target.outerHeight());
  });
  if ("onwebkitspeechchange" in document.createElement("input")) {
  var editorOffset = $('#editor').offset();
  $('#voiceBtn').css('position','absolute').offset({top: editorOffset.top, left: editorOffset.left+$('#editor').innerWidth()-35});
  } else {
  $('#voiceBtn').hide();
  }
 };
 function showErrorAlert (reason, detail) {
 var msg='';
 if (reason==='unsupported-file-type') { msg = "Unsupported format " +detail; }
 else {
 console.log("error uploading file", reason, detail);
 }
 $('<div class="alert"> <button type="button" class="close" data-dismiss="alert">×</button>'+ 
 '<strong>File upload error</strong> '+msg+' </div>').prependTo('#alerts');
 };
 initToolbarBootstrapBindings(); 
 $('#editor').wysiwyg({ fileUploadError: showErrorAlert} );

最后是HTML代码：
