I want to invoke Erlang GS in Browser window.
For that I want to call GS in Erlang through Javascript.
I have very less idea on how this can be implemented. Please help me to sort out this problem. |

Hi,
If you want to call Erlang modules from JavaScript running in the browser, you would need your HTTP server to transform HTTP requests into Erlang function calls. One way of doing it is to setup Yaws (Erlang HTTP server) and develop some *.yaws pages that would call functions you need and then return what you need. Yaws also supports json, so you can use ajax-like scripts.
Last week we have released ErlangWeb - a platform for developing web applications in Erlang. It is built on top of Yaws and gives couple of very handy features. One of those are controllers. You can easily call Erlang functions by sending http requests to url like: http://localhost/app/module/funcion This will call module:function(). ErlangWeb can return html or json data. More details can be found in a tutorial included in the zip. You can download ErlangWeb from http://sourceforge.net/project/showfiles.php?group_id=231549
We are working on a new release of ErlangWeb, so if you will find it useful, keep an eye on the project web page.
