Using global variable versus hidden field

Rasmita,

Global Variables in scripting , you would still be using that inside the .js file or among the script functions and the value you assign to them still cannot be used by your server side code  but lets say you want a value to be shared between the server side code and the client side code i.e you want to pass some value from client side to server side or vice verse when you are not using any web methods / AJAX calls then you make use of hidden fields .


Please let me know if you have questions still .

Hi Rasmita,

I am assuming you are refering to  web development.  To me global variable are typically stored on the server side. Hidden field values would be on the client side and example retrieved on a client side event without having to make a round trip to the server and then back to  the client.  

If you just need this variable in the client script I would suggest using a hidden field or if you want it stored you could use a cookie.

Global Variables: Those variables which can be used throughout the application are called as global variables. Also we call them as Static variables. When the variables are shared by more than one process or method, we can make the variable as Static. Like we have the folder name called Asp_code which contains the classes with the static methods and variables. This class gets initialized one and can be used throughout your application. Like we use the properties to keep the connection string data using Static variables. These variables can be access directly by using the class name without creating the object of the class or without instantiating the class.
There is a very nice article on – "Hidden field".. Please go through this.
