Bootstrap 可視化HTML編輯器之summernote,用其官網上的介紹就是“Super Simple WYSIWYG editor”,不過在我看來,與bootstrap中文官網上提供的“bootstrap-wysiwyg”要更simple,更漂亮,更好用!
雖然我之前嘗試過使用bootstrap-wysiwyg,可參照Bootstrap wysiwyg富文本數據如何保存到mysql,但事后諸葛亮的經驗告訴我,summernote絕對是更佳的富文本編輯器,這里對其工作team點三十二個贊!!!!!
經過一天時間的探索,對summernote有所掌握,那么為了更廣大前端愛好者提供便利,我將費勁一番心血來介紹一下summernote,超級福利啊。
一、官方API和源碼下載
工欲善其事必先利其器,首先把summernote的源碼拿到以及對應官方API告訴大家是首個任務!
官網(demo和api)?
github源碼下載,注意下載開發版
二、效果圖
效果圖1?
效果圖2?
效果圖3?
三、開講內容
大的方向為以下三個內容:
①、summernote的頁面布局

- <!DOCTYPE html>html5的標記是必須的,注意千萬不能是<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">這種doctype,否則summernote的組件顯示怪怪的,按鈕的大小布局不一致,這里就不再上圖了,但是千萬注意!
- bootstrap 的版本號最好為v3.3.5
1、布局div
<div class="summernote" name="description" placeholder="請對項目進行詳細的描述,使更多的人了解你的" action="${ctx}/file">${deal.description}</div>- 1
- 1
相信你也看到了我為div加上的三個屬性name、placeholder、action,那么我們來詳細介紹一下三個屬性的作用:
另外${deal.description}其實你不需要太多關注,和textarea的賦值的用法一致,就是單純的顯示保存后的內容。
2、summernote初始化
$('div.summernote').each(function() {var $this = $(this);var placeholder = $this.attr("placeholder") || '';var url = $this.attr("action") || '';$this.summernote({lang : 'zh-CN',placeholder : placeholder,minHeight : 300,dialogsFade : true,// Add fade effect on dialogsdialogsInBody : true,// Dialogs can be placed in body, not in// summernote.disableDragAndDrop : false,// default false You can disable drag// and drop});});- 1

使用jQuery獲取到頁面上的summernote,對其進行初始化,我們來詳細介紹列出參數的用法(先不介紹圖片上傳的onImageUpload 方法)。
②、summernote從本地上傳圖片方法
1、前端onImageUpload方法
假如問度娘如下的話:“onImageUpload方法怎么寫?”,度娘大多會為你找到如下回答:
$(\'.summernote\').summernote({height:300,onImageUpload: function(files, editor, welEditable) {sendFile(files[0],editor,welEditable);}});});function sendFile(file, editor, welEditable) {data = new FormData();data.append("file", file);url = "http://localhost/spichlerz/uploads";$.ajax({data: data,type: "POST",url: url,cache: false,contentType: false,processData: false,success: function (url) {editor.insertImage(welEditable, url);}}); } </script>- 1

以上資源來自于stackoverflow。
但其實呢,summernote-develop版本的summernote已經不支持這種onImageUpload寫法,那么如今的寫法是什么樣子呢?參照summernote的官網例子。
onImageUpload
Override image upload handler(default: base64 dataURL on IMG tag). You can upload image to server or AWS S3: more…
// onImageUpload callback $('#summernote').summernote({callbacks: {onImageUpload: function(files) {// upload image to server and create imgNode...$summernote.summernote('insertNode', imgNode);}} });// summernote.image.upload $('#summernote').on('summernote.image.upload', function(we, files) {// upload image to server and create imgNode...$summernote.summernote('insertNode', imgNode); });- 1

那么此時onImageUpload的具體寫法呢?(后端為springMVC):
callbacks : {// onImageUpload的參數為files,summernote支持選擇多張圖片onImageUpload : function(files) {var $files = $(files);// 通過each方法遍歷每一個file$files.each(function() {var file = this;// FormData,新的form表單封裝,具體可百度,但其實用法很簡單,如下var data = new FormData();// 將文件加入到file中,后端可獲得到參數名為“file”data.append("file", file);// ajax上傳$.ajax({data : data,type : "POST",url : url,// div上的actioncache : false,contentType : false,processData : false,// 成功時調用方法,后端返回json數據success : function(response) {// 封裝的eval方法,可百度var json = YUNM.jsonEval(response);// 控制臺輸出返回數據YUNM.debug(json);// 封裝方法,主要是顯示錯誤提示信息YUNM.ajaxDone(json);// 狀態ok時if (json[YUNM.keys.statusCode] == YUNM.statusCode.ok) {// 文件不為空if (json[YUNM.keys.result]) {// 獲取后臺數據保存的圖片完整路徑var imageUrl = json[YUNM.keys.result].completeSavePath;// 插入到summernote$this.summernote('insertImage', imageUrl, function($image) {// todo,后續可以對image對象增加新的css式樣等等,這里默認});}}},// ajax請求失敗時處理error : YUNM.ajaxError});});} }- 1

2.1、為springMVC增加文件的配置
<bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver" p:defaultEncoding="UTF-8"><property name="maxUploadSize" value="1024000000"></property></bean><mvc:annotation-driven conversion-service="conversionService" /><bean id="conversionService"class="org.springframework.format.support.FormattingConversionServiceFactoryBean"><property name="converters"><list><!-- 這里使用string to date可以將dao在jsp到controller轉換的時候直接將string格式的日期轉換為date類型 --><bean class="com.honzh.common.plugin.StringToDateConverter" /> <!-- 為type為file類型的數據模型增加轉換器 --><bean class="com.honzh.common.plugin.CommonsMultipartFileToString" /></list></property></bean>- 1

后端文件保存方法也非常簡單,懂Java的同學都可以看得懂,那么對于后端不使用springmvc的同學,你可以再找找方法。
辛苦的介紹完前兩節后,我們來一個動態圖看一下效果吧!?
③. summernote所在form表單的數據提交
這里,我們再回顧一下summernote所在的form表單,其中還包含了一個普通file的input標簽,也就是說,該form還需要上傳一張項目封面。
<form class="form-horizontal required-validate" action="#" enctype="multipart/form-data" method="post" onsubmit="return iframeCallback(this, pageAjaxDone)">- 1
- 1
先看一下form的屬性:
1、iframeCallback
function iframeCallback(form, callback) {YUNM.debug("帶文件上傳處理");var $form = $(form), $iframe = $("#callbackframe");var data = $form.data('bootstrapValidator');if (data) {if (!data.isValid()) {return false;}}// 富文本編輯器$("div.summernote", $form).each(function() {var $this = $(this);if (!$this.summernote('isEmpty')) {var editor = "<input type='hidden' name='" + $this.attr("name") + "' value='" + $this.summernote('code') + "' />";$form.append(editor);} else {$.showErr("請填寫項目詳情");return false;}});if ($iframe.size() == 0) {$iframe = $("<iframe id='callbackframe' name='callbackframe' src='about:blank' style='display:none'></iframe>").appendTo("body");}if (!form.ajax) {$form.append('<input type="hidden" name="ajax" value="1" />');}form.target = "callbackframe";_iframeResponse($iframe[0], callback || YUNM.ajaxDone); } function _iframeResponse(iframe, callback) {var $iframe = $(iframe), $document = $(document);$document.trigger("ajaxStart");$iframe.bind("load", function(event) {$iframe.unbind("load");$document.trigger("ajaxStop");if (iframe.src == "javascript:'%3Chtml%3E%3C/html%3E';" || // For// Safariiframe.src == "javascript:'<html></html>';") { // For FF, IEreturn;}var doc = iframe.contentDocument || iframe.document;// fixing Opera 9.26,10.00if (doc.readyState && doc.readyState != 'complete')return;// fixing Opera 9.64if (doc.body && doc.body.innerHTML == "false")return;var response;if (doc.XMLDocument) {// response is a xml document Internet Explorer propertyresponse = doc.XMLDocument;} else if (doc.body) {try {response = $iframe.contents().find("body").text();response = jQuery.parseJSON(response);} catch (e) { // response is html document or plain textresponse = doc.body.innerHTML;}} else {// response is a xml documentresponse = doc;}callback(response);}); }- 1

貼上全部代碼以供參考,但是這里我們只講以下部分:
// 富文本編輯器$("div.summernote", $form).each(function() {var $this = $(this);if (!$this.summernote('isEmpty')) {var editor = "<input type='hidden' name='" + $this.attr("name") + "' value='" + $this.summernote('code') + "' />";$form.append(editor);} else {$.showErr("請填寫項目詳情");return false;}});- 1

- 通過form獲取到summernote對象$this 后,通過!$this.summernote('isEmpty')來判斷用戶是否對富文本編輯器有內容上的填寫,保證不為空,為空時,就彈出提示信息。
- $this.summernote('code')可獲得summernote編輯器的html內容,將其封裝到input對象中,name為前文中div提供的name,供后端使用。
這里其他地方就不做多解釋了,詳細可參照Bootstrap wysiwyg富文本數據如何保存到mysql。
保存到數據庫中是什么樣子呢?

頁面效果為:
2、新版iframeCallback方法
var $form = $(form), $iframe = $("#callbackframe");YUNM.debug("驗證其他簡單組件");var data = $form.data('bootstrapValidator');if (data) {if (!data.isValid()) {return false;} }// 富文本編輯器 $("div.summernote", $form).each(function() {var $this = $(this);if ($this.summernote('isEmpty')) {} else {YUNM.debug($this.summernote('code'));// 使用base64對內容進行編碼// 1.解決復制不閉合的html文檔,保存后顯示錯亂的bug// 2.解決文本中特殊字符導致的bugvar editor = "<input type='hidden' name='" + $this.attr("name") + "' value='" + $.base64.btoa($this.summernote('code')) + "' />";$form.append(editor);} });YUNM.debug("驗證通過");- 1

比對之前的代碼,可以發現代碼有兩處發生了變化:
3、base64的使用方法
js端我在Bootstrap wysiwyg富文本數據如何保存到mysql這篇文章中做了說明,此處不再說明。
可能會有同學需要JavaScript端的base64編碼,而需要在springMVC后端使用base64的解碼,那么此處介紹一個jar包(Java Base64.jar),使用方法很簡單,下載好jar包后,就可以使用如下方法解碼:
import it.sauronsoftware.base64.Base64;deal.setDescription(StringEscapeUtils.escapeHtml(Base64.decode(description, "utf-8")));- 1

4、summernote加入到bootstrap validator中
<div class="form-group"><label for="" class="col-md-1 control-label">項目詳情</label><div class="col-md-10"><div class="summernote" name="description" data-bv-excluded="false" data-bv-notempty placeholder="請對項目進行詳細的描述,使更多的人了解你的云夢"action="${ctx}/file">${deal.description}</div></div> </div>- 1

在summernote的callbacks中加入onChange 、onInit,當文本域發生變化、初始化時,對summernote在form中的驗證字段進行狀態的更新,validator中使用updateStatus方法。
/*** Update all validating results of field** @param {String|jQuery} field The field name or field element* @param {String} status The status. Can be 'NOT_VALIDATED', 'VALIDATING', 'INVALID' or 'VALID'* @param {String} [validatorName] The validator name. If null, the method updates validity result for all validators* @returns {BootstrapValidator}*/updateStatus: function(field, status, validatorName) { OK,等補上以上兩個內容后,整個summernote就完整了。總結
以上是生活随笔為你收集整理的Bootstrap 可视化编辑器summernote的全部內容,希望文章能夠幫你解決所遇到的問題。
