With Eval function, i am able to parse JSON string in IE and Chrome. But i am not able to parse json string using Eval function in Firefox. Can you please give the code to solve this problem.

Are you parsing JSON in client?
What error you are getting. Can you show the JSON string ?
Are you doing like this
var jsonOBJ = eval('(' + data + ')');
I think it works in Firefox as well.. 
|
|
|
|
|
this is my json string. I am using the eval function the same you have show.
Example of json string
{"Store":[{"Store_id":1325,"StoreName":"s1","StoreCode":1}]}
|
|
|
|
|
But when I try this, it works perfectly in firefox as well.. .
I used
function elemJSON() {
var elem = '{ "Store": [{ "Store_id": 1325, "StoreName": "s1", "StoreCode": 1}] }';
var jsonobj = eval('(' + elem + ')');
alert(jsonobj.Store[0].Store_id);
}
<br />
<input type="button" onclick="elemJSON();" value="JSON Parse" />
and it showed me 1325 in both the browsers(IE And FF)...

Hi all,
I am sending id to the another page but right now it is in readable format how to encrypt.

This was enormously helpful code to me. I searched forever to find something this straightforward. You saved me many hours.
I wanted to add something another reader might find useful. I needed to add URL encoding so that the encrypted string would be ready for transport over HTTP. To do this (in vb.net) I add a reference to System.Web and use the HTTPUtility.URLEncode class to transform it into a string
Imports System.Web
strEncoded = HttpUtility.UrlEncode(strEncrypted)
So, the steps are:
1. Store a string of query parameters
2. Encrypt it using code above
3. Encode it with URLEncode
4. Send it through as query string (one string of apparently-random characters)
5. Receive it on the other side as one big query string
6. use HTTP.Utility.URLDecode to get it back to a regular string
6. Decrypt it using the code above
7. Write a routine to parse it out because you can't use Request.QueryString("AB") for this purpose. You have to come up with your own such as request_equerystring("AB"). Some code for this was written up in the following article on the subject that talks about the process but I could not get their encrypt and decrypt to work out-of-the-box in vb.net.
In my application, the data I am passing can only be obtained using a windows.form because it uses local data that is not brower-accessible. There are plenty of examples of ASP to ASP querystring passing out there where you can use server.transfer. But, this is the only simple-to-follow reference I could find to calling up a browser with encrypted query strings from vb.net (that worked on first try).
Encrypting the Information Passed From the Query String

No thanks.
Exactly same thing is right here[^]. As soon as I read "So, the steps are" it struck that I have seen it somewhere. Hence the reply.

Encrypt with any encryption, Encode in base64 string and then pass to the querystring using UrlEncode.
Remember base64 is essential.
