C#(WinForm)实现HTML编辑器方法
做Web开发时,我们经常会用到HTML富文本框编辑器来编写文章或产品描述的详细内容,常用的编辑器有FCKEditor、CKEditor 、TinyMCE、KindEditor和ueditor(百度的),
我们知道WinForm上有一个webBrowser控件,本文正是采用webBrowser结合Web上的HTML编辑器KindEditor来实现的,KindEditor是一个国人写的编辑器,轻量级用起来挺不错,至少我知道目前拍拍和开源中国就是用此编辑器。
KindEditor的官方地址为:http://kindeditor.net/down.php
首先我们需要去官网或者Github:https://github.com/kindsoft/kindeditor下载一份代码,然后解压到我们项目的bin文件夹下,然后在bin/KindEditor目录下新建一个名字为e.html的html文件,并键入以下代码:
<!doctype html> <html> <head> <meta charset="utf-8" /> <title>Html Editor</title> <script charset="utf-8" src="kindeditor.js"></script> <script charset="utf-8" src="lang/zh_CN.js"></script> <script> window.onerror = function () { return true; }; var editor; var contentSeted = false; KindEditor.ready(function (K) { editor = K.create('#details', { allowFileManager: false, allowImageUpload: false, resizeType: 0, //不能更改大小 fullscreenMode: true, items: [ 'undo', 'redo', '|', 'cut', 'copy', 'paste', 'plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright', 'justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript', 'superscript', '|', 'clearhtml', 'quickformat', 'selectall', 'flash', 'table', 'hr', 'emoticons', 'baidumap', 'pagebreak', '/', 'formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image', 'multiimage', 'link', 'unlink', '|', 'template', 'code', 'source', 'preview', ], afterChange: function () { if (editor && contentSeted) window.external.RequestContent(editor.html()); } }); setContent(window.external.GetContent()); }); function setContent(content) { if (editor) { contentSeted = false; editor.html(content); contentSeted = true; } } </script> </head> <body style="padding: 0; margin: 0;"> <textarea id="details" style="display: block; width: 680px; height: 100%; visibility: hidden;"></textarea> </body> </html>
如果在Web上用过 KindEditor的朋友对以上代码应该不陌生,因为它实际上就是初始化一个 HTML编辑器而已,我们还在代码中定义了一个setContent方法,该方法就是用来设置HTML编辑器的内容,我们在C#代码中需要调用该方法.
好了,下面我们回到WinForm上面,我们在界面上拉一个webBrowser控件,cs里键入以下代码:
namespace WinformHTMLEditor { [ComVisible(true)] public partial class Form1 : Form { string content = ""; public Form1() { InitializeComponent(); this.webBrowser1.Url = new System.Uri(Application.StartupPath + "\\kindeditor\\e.html", System.UriKind.Absolute); this.webBrowser1.ObjectForScripting = this; } public void SetDetailContent() { webBrowser1.Document.InvokeScript("setContent", new object[] { content }); } public string GetContent() { return content; } public void RequestContent(string str) { content = str; richTextBox1.Text = content; } private void richTextBox1_TextChanged(object sender, EventArgs e) { if (richTextBox1.Focused) { content = richTextBox1.Text; SetDetailContent(); } } private void webBrowser1_Resize(object sender, EventArgs e) { this.webBrowser1.Refresh(); } } }
