How to use javascript variable in BSP/ABAP and vice versa

Question

Hello Experts,
In IC WEBCLIENT, there is a view.In the view.htm i want to fetch  the screen resolution and as per the resolution i want set the width of that view.
1, I wrote the below  javascript to fetch the screen resolution.
   Can i use a notmal ABAP variable inside the javascript? and   If i use can i access that variable after the javascript.?
   Can i assign a javascript variable to a nrmal abap variable??
   The code sample  is like :
Start of javascript
   if (screen,width == 1024 )
     lv_width = 500  "lv_width is an ABAP variable.
  else
    lv_width = 700
**END OF JAVASCRIPT
   **Now i want to use lv_width  to assign to a table view attribute(Width)
<crmc: tableview..
                width = <%= lv_width >
the code is not giving any error. But the problem is that lv_width is not giving the correct value, its getting initialized to initial value...
Requesting the experts to please provide some suggestions/solution for the above issue.
Thanks and Regards

Hello Sudhansu,
First of all there was a little mistake at my previous answer:
you got lw_width = 700
because at Server Side you have following code:
lw_width = 500.
lw_width = 700.
but if you were writing your code like this:
<%=lw_width %> = 700.
then you will get the result that I was talking about : 0 = 700
Sorry for the mistake
Now for your question:
if you want to get a value from the server and assign it to JScript variable you should write like this :
var aaa;
aaa = <%=lw_width %>;
this code assign the server variable lw_width value into aaa  JScript varible.
I'm not sure what exactly you want to do but look at this link:

to get the idea how to get and use Screen Resolution variables at your JScript code.
Good luck
