The syntax of JavaScript and PHP is very similar. How similar is shown by the following function that I wrote to generate a random password:
PHP code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | <?php function randomPassword($length){ $password = ""; for($i=0; $i<$length; $i++){ $func = rand(0,2); if($func == 0) $password = $password.chr(rand(48,57)); else if($func == 1) $password = $password.chr(rand(65,90)); else if($func == 2) $password = $password.chr(rand(97,122)); } return $password; } $randomPassword = randomPassword(20); echo($randomPassword); ?> |
JavaScript code:
<script type="text/javascript" line="1"> function rand(min,max){ if (arguments.length === 0){ min = 0; max = 32767; } return Math.floor(Math.random() * (max - min + 1)) + min; } String.prototype.chr = function(code){ return String.fromCharCode(code); } function randomPassword($length){ $password = ""; for($i=0; $i<$length; $i++){ $func = rand(0,2); if($func == 0) $password += $password.chr(rand(48,57)); else if($func == 1) $password += $password.chr(rand(65,90)); else if($func == 2) $password += $password.chr(rand(97,122)); } return $password; } $randomPassword = randomPassword(20); document.write($randomPassword); </script> |
