Re: web2py view to controller value passing and vice versa

[Tim Richardson]

how to get the returned value in view again??

The view is executed by the server, so variables included in the view are provided by the web2py server process executing code at the time the content is sent to the browser; you are returning a value via ajax which sends it to the client (the browser) some point after the view has been generated.

When you say you want the value in the "view", do you really mean you want it on the web page in the client? As Tim pointed out below, the view is a file on the server that is executed on the server -- it generates an HTML page that is then sent to the browser -- however, the view itself is not in the browser.

It would help if you could explain exactly what you are trying to do. What would you like to happen when the user clicks the link/button?

View:

onclick='ajax("{{=URL('default', 'test', args=[textname[i], '2', 'tamil'])}}",[], ":eval");'

controller:

if (request.args[2]=="tamil"):
        if (int(request.args[1])==1):

Did you read my response here: https://groups.google.com/d/msg/web2py/yC9e4gy-t1k/SPpTjGyYLQQJ? We need more information about what you are trying to do? Where is that "onclick" handler, and what do you want to happen on the page when it is clicked?
