Problem #1
- Ssh to aurora.smith.edu using your 231a-xx account.
- Go into your account's public_html directory.
- Create a file with emacs, and call it javascriptTest.html.
- Store the following code into it:
<html> <body> <script type="text/javascript"> <!-- var a = 33; var b = 10; var c = "Test"; var i = 0; var linebreak = "<br />"; document.write("sum_i=0^100 = "); sum = 0; for ( i=0; i<=100; i++ ) { sum = sum + i; } document.write( sum ); document.write(linebreak); //--> </script> Example of Javascript arithmetic. <br /> </body> </html>
- Make the file readable:
chmod a+r javascriptTest
- In your favorite browser, go to this URL: http://cs.smith.edu/~231a-xx/testJavascript.html and replace xx by your 2-letter Id.
- You should see a page similar to the one shown below.
