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">×</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。
