Calling a controller from javascript? - El Forum - 11-19-2008

I am trying to submit a form via ajax using prototype )the ajax libraries were just too much for so little).

Right now I've got this:

Code:
var url = '/CIDIRECTORY/CONTROLLERNAME/saveOrder/';

    new Ajax.Request(url, {

        parameters: { hiddenNodeIds: thestring },

        method: 'post',

        onComplete: function(truck) {

            alert(url);

        }

    });

But it doesn't seem to be calling the function in the controller. How do I get it to do that?

You haven't disclosed how you are actually executing this JS. It is constructed properly...but how does it get implemented, started up, called? I can't tell by looking at this snippet.

Put it inside a function call if it isn't already...might see improvement.

I've been in such situation before... Confused

hut:
and I found that I ran into some trouble in loading the prototype function...
but here's how I describe and solved it...

first..
loading the prototype.js file...
when using html script tag to load the prototype.js file, I found problem to locate the source file...
so I just put them in the ci_directory/js_library/ and then call it in the view file with the html script tag :

Code:
&lt;script src="&lt;?=base_url()?&gt;js_library/your_jsfile.js" type="text/javascript"&gt;

&lt;/script&gt;

so the src value will be something like:
http://your_server/ci_directory/js_library/your_jsfile.js

second..
calling the Ajax.Request... (or in my case I use the Ajax.Updater...)
to call other controller, I use these codes in the view file...

Code:
&lt;... onclick="new Ajax.Updater('yourdiv_id','&lt;?=base_url()?&gt;index.php/controller/etc')"&gt;

so from the browser view source your Ajax url is:
http://your_server/ci_directory/index.php/controller/etc

I think it'll works the same in your Ajax.Request function...

well it works on my page, I hope it works on yours too...
feel free to ask...
and if anybody had some other ideas, please share it, since I'm still a newbie also... :-P
PS: sorry if my english is poor... :-S
I'm still having troubles translating my thought to english!

AndrewM - that's perfect! Thanks!! I didn't include the index.php in the url which did the trick. Thanks much.

I crapped out and just used an iframe, but now I took it out. Also, you're english is fine! I couldn't tell you weren't a native speaker until you said so.
