<html> <head> <title>JavaScript Math random() Method</title> </head> <body> <script type="text/javascript"> var value = Math.random( ); document.write("First Test Value : " + value ); var value = Math.random( ); document.write("<br />Second Test Value : " + value ); var value = Math.random( ); document.write("<br />Third Test Value : " + value ); var value = Math.random( ); document.write("<br />Fourth Test Value : " + value ); </script> </body> </html>
這將產生以下結果:
