這篇文章給大家介紹ASP.NET中怎么配置KindEditor文本編輯器,內容非常詳細,感興趣的小伙伴們可以參考借鑒,希望對大家能有所幫助。
1.什么是KindEditor
KindEditor 是一套開源的在線HTML編輯器,主要用于讓用戶在網站上獲得所見即所得編輯效果,開發人員可以用 KindEditor 把傳統的多行文本輸入框(textarea)替換為可視化的富文本輸入框。 KindEditor 使用 JavaScript 編寫,可以無縫地與 Java、.NET、PHP、ASP 等程序集成,比較適合在 CMS、商城、論壇、博客、Wiki、電子郵件等互聯網應用上使用。
2.前期準備
到官網下載最新版的KindEditor 4.11,解壓文件后可得
文件結構:
asp:與asp結合的示例代碼
asp.net:與asp.net結合的示例代碼
attached:上傳文件的根目錄,可在相關的代碼中修改
examples:功能演示的示例代碼
jsp:與jsp結合的示例代碼
lang:語言包
php:與php結合的示例代碼
plugins:控件的功能代碼的實現
kindeditor.js:配置文件
kindeditor-min.js:集成文件
由于使用的是ASP.NET,所以將不需要的文件夾刪掉。其中在asp.net中demo.aspx是參考代碼,也可以刪掉。
3.配置KindEditor
(1)新建網站,將精簡后的kindeditor文件夾放到網站根目錄下下,并且引用kindeditor/asp.net/bin/LitJSON.dll文件。
(2)新建index.aspx文件,引入相關文件
<link href="kindeditor/plugins/code/prettify.css" rel="stylesheet" type="text/css" /> <script src="kindeditor/lang/zh_CN.js" type="text/javascript"></script> <script src="kindeditor/kindeditor.js" type="text/javascript"></script> <script src="kindeditor/plugins/code/prettify.js" type="text/javascript"></script> <script type="text/javascript"> KindEditor.ready(function (K) { var editor = K.create('#content', { //上傳管理 uploadJson: 'kindeditor/asp.net/upload_json.ashx', //文件管理 fileManagerJson: 'kindeditor/asp.net/file_manager_json.ashx', allowFileManager: true, //設置編輯器創建后執行的回調函數 afterCreate: function () { var self = this; K.ctrl(document, 13, function () { self.sync(); K('form[name=example]')[0].submit(); }); K.ctrl(self.edit.doc, 13, function () { self.sync(); K('form[name=example]')[0].submit(); }); }, //上傳文件后執行的回調函數,獲取上傳圖片的路徑 afterUpload : function(url) { alert(url); }, //編輯器高度 width: '700px', //編輯器寬度 height: '450px;', //配置編輯器的工具欄 items: [ 'source', '|', 'undo', 'redo', '|', 'preview', 'print', 'template', 'code', 'cut', 'copy', 'paste', 'plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright', 'justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript', 'superscript', 'clearhtml', 'quickformat', 'selectall', '|', 'fullscreen', '/', 'formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image', 'multiimage', 'flash', 'media', 'insertfile', 'table', 'hr', 'emoticons', 'baidumap', 'pagebreak', 'anchor', 'link', 'unlink', '|', 'about' ] }); prettyPrint(); }); </script>
(3)在頁面中添加一個textbox控件,將id命名為content,把屬性"TextMode"屬性改為Multiline
<body> <form id="form1" runat="server"> <div id="main"> <asp:TextBox id="content" name="content" TextMode="MultiLine" runat="server"></asp:TextBox> </div> </form> </body>
(4)在瀏覽器查看
4.附件上傳原理
在asp.net文件夾下有兩個重要的file_manager_json.ashx,upload_json.ashx,一個負責文件管理,一個負責上傳管理。你可以根據自己需求進行相關修改。
原理:通過實現接口IHttpHandler來接管HTTP請求。
file_manager_json.ashx
