Hi all,
Like the Hashtable in .Net, I want to have a collection in javascript in order to store some predefined key value pair.

Is there any such collection available in JavaScript?

Kindly help me in this regard.

Dear Vasu,

I have downloaded and included in my applcation.

Now in the page onload client side event I have invoked a jayavascript function. In that function I have declared a variable and initialized as follows:

var keyValuePair;
keyValuePair = new Hashtable();

It is giving "Hastable is undefined".

Can you tell me why?

And in what way it has to be used in the application.

Best Regards,
M. J. Jaya Chitra

Did you include the prototype definitions in the article? That actually defines an object called 'HashTable'.

There is a downloadable example of hashtable:

http://www.comet.co.il/en/articles/hash/hashtable.zip[^]

Nevertheless, the code snippets near the top of the article like

Hashtable.prototype ... are declarations.

You ought to include the function Hashtable and its associated get and put to define the structure.

If you are building a querystring from serverside, use Server.UrlEncode().

You can encode the querystring from JavaScript, you ought to use escape function.
