The $H() function converts objects into enumerable Hash objects that resemble associative arrays.
The $H function is the shorter way to obtain a hash.
$H([obj]) |
<html> <head> <title>Prototype examples</title> <script type="text/javascript" src="/javascript/prototype.js"> </script> <script> function ShowHash() { //let's create the object var a = { first: 10, second: 20, third: 30 }; //now transform it into a hash var h = $H(a); alert( h.toQueryString()); } </script> </head> <body> <p>Click "Show Value" button to see the result</p> <form> <input type="button" value="Show Value" onclick="ShowHash();"/> </form> </body> </html> |
This will display following result:
first=10&second=20&third=30 |
To understand it in better way you can Try it yourself.
