摘要：大家好，今天给大家介绍关于记事本源码（java记事本源代码）的相关内容，详细讲解如何用浏览器打开用记事本编写的代码，用html5编写手机记事本的纯代码文档，求简短vbs代码三个等，希望可以帮助到您。
如何用浏览器打开用记事本编写的代码,1.打开计算机，单击桌面上的鼠标，在菜单栏中选择“新建”，然后选择“文本文档”，创建“文本文档”; 2.右键单击新的“文本文档”文档后的文本，在菜单栏中的“打开模式”中，“使用记事本打开”，或将默认打开模式设置为“记事本”;想要编辑Web代码; 4.输入要编辑的Web代码后，可以单击“保存”按钮（您也可以按Ctrl + S快捷方式），或“另存为”; 5，在计算机桌面上找到编辑器已保存的文本文档，在右键单击菜单栏中选择“重命名”，将文档末尾的“.txt”格式更改为“.html”格式; 6，“.txt”格式在文档结束时更改为“.html”在“格式之后，文本文档图标将成为Web模式; 7.打开文本文本ENT转变为网页，您可以实现文本以编辑浏览器中的HTML。
用html5编写手机记事本的纯代码文档,单击Windows桌面上的[开始] - >选择[所有程序] - > [附件] - > [记事本]，打开一个记事本。在打开的记事本中输入HTML代码，如下所示：编辑HTML文件后，选择[文件] - > [保存]或按Ctrl + S键键选择弹出窗口中的[保存为]对话框[保存“对话框类型]是[所有文件]，然后将文件扩展名设置为.html或.htm。如下所示：步骤读取4单击[保存]以保存文件。浏览器预览，请移动另一个共享体验[使用浏览器查看HTML5文件]
求简短vbs代码三个,wscript.createobject（“sapi.spvoice”）。说“我爱你”wscript.createobject（“wscript.shell”）。运行“notepad.exe”msgbox“弹出提示”

- 求知道的大神告诉我该怎么用记事本输入代码,输入什么代码啊网页的吗？？？<html><head></head><body>hello word</body></html>这段代码复制到记事本，文件改成html或者直接用浏览器打开，就是一个网页
