That "append to the current page" stuff is ajax. Web2py has a very handy wrapper for ajax, the LOAD() helper. <URL: http://web2py.com/books/default/chapter/29/12/components-and-plugins#LOAD> The target argument specifies where on the page to put the results ... you need a DIV that matches. My example, which goes in the view file: {{=LOAD(c='myhosts', f='myhosts2.load', target='my_hosts', content="something's happening", ajax=True)}} To continually append more messages, instead of replacing old with new, you would need to have multiple DIVs, and point to a different DIV for each message. The above code will run automatically on initial page load, which you may or may not want, depending on whether you want messages from a previous visit to appear. I have done some stuff where I want a user to click a button to get more information, and so I fabricate an html string in the controller, put the string into the dict I return, and the view displays the string in the appropriate part of the page. The string includes something like this: dis_str = CAT(dis_str, TT(" "), A("mystuff list", _href=URL("mystuff.html", vars=dict( ipaddr=ipaddr, hnam e=hname, tdisk=index)), _style="visibility:visible", _id="stuffh"), TT("\n "), TAG.BUTTON('mystuff list', _type="button", _name= "val2controller", _value=val2controller, _onclick='$("#mystuff_div").html("updating ..");ajax("mystuff.load", ["val2controller"], "mystuff_div")', _style="display:none", _id="mystuffa")) I think you can manipulate the DIV name either server side or client side, but I haven't tested any code for that purpose. Server side: keep the name in the session object, update it on each load, and in the view/controller/response.load file use the DIV helper after you display your messages. This will end up nesting the DIVs, but I don't think that's a problem. Caveat coder. Client side: use javascript to tap into the onclick path, and insert a new DIV into the DOM, then use that DIV's name in the ajax call. You may have to go direct to ajax in this scheme, rather than using the LOAD helper. This will require a little more study, but look at the other material in the book's component chapter, and it may help you out. Note that using ajax requires that your users allow javascript from your site, and there are plenty of people reluctant to do that, but if they are going to trust your site they might as well trust your site. Using something like noscript gives them some confidence that they protected against cross-site scripting attacks, but they can whitelist your site to view your pages. (noscript is for firefox; I don't know the equivalent in other browsers, but chrome has some of the features built in but not as easily tuned.) Good luck! I hope this helps, and that I haven't fed you too much bogus information. /dps -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
