How to Write Script to Launch a Desktop Application From a Web Browser

Javascript is a language used to interact with a user's browser after a web page loads. This scripting language can be used to open a program on your computer. It is beneficial for businesses that have web-based applications for internal applications. Javascript code opens the file and the program, such as a PDF file that opens the Adobe Acrobat software.

Instructions

1. Right-click the HTML file you want to use to open the application. Select "Open With." Double-click the "Notepad" icon to open the HTML file in your text editor.

2. Create the script block in the code file. The "<script>" and "</script>" tags enclose all of your Javascript code. Add the following code to your file:

   <script> </script>

3. Add the code to open the program. Type the following code into the script tags created in Step 2:

   File="cmd.exe";

   WSH=new ActiveXObject("WScript.Shell");

   WSH.run(File);

   In this example, the Windows command line program is started.

4. Click the "File" menu option in Notepad and select "Save" to save the changes.
