Hey can anyone help me convert a javascript array into a ruby array.
Ive been struggling with this since friday to no avail. This is the
function with the ajax.request call that is supposed to convert the
array using JSON, but I keep getting a 422(Unprocessable Entity)
error. Im not sure what is wrong.
function test()
{
for(i=1;i<22;i++){
if
(document.getElementById(i+''d'').className
="selected"){
myArray.push(i);
}
}
new Ajax.Request(''/appointments/array/'',
{method:''get'',postBody:"''data=''+myArray.toJSON"});
}
Thanks for any input!

Sorry, that ajax.request method should be a put, so:
new Ajax.Request(''/appointments/array/'',
{method:''post'',postBody:"''data=''+myArray.toJSON"});

Yea, I am trying to just use the link_to_remote helper now, but aside
from converting the array and using JSON, I can''t even get the
link_to_remote to route now. I am using:
<%= link_to_remote ''Click me'', :url => {:action =>
"update"}, :with
=> ''test'' %>
and the only action that works successfully is the new action, so
<%= link_to_remote ''Click me'', :url => {:action =>
"new"}, :with =>
''test'' %>
routes successfully, but this is not what i want. I get this error in
firebug:
POST http://localhost:3000/appointments/update500 241ms.
Do you have any idea why this is happening?

This is the line that caused the error: <%= link_to_remote ''Click
me'', :url => {:controller => "appointments", :action

follow the

Yea, you were right, its been a long day....but i have finally figured
it out. Thanks for your help. For anyone who is trying to convert a
javascript array to a ruby array and pass the array to the controller
you can follow this advice:
create a javascript function that returns the array with the toJSON()
function, so like this:
function example(){
myArray = new Array();
.......
return myArray.toJSON()
}
you can then send this converted array to an action using the
link_to_remote ajax helper by calling your javascript function within
the :with parameter like so:
<%= link_to_remote ''Click me'', :url => {:action =>
"array"}, :with =>
"''data=''+test()", :update =>
''testing''%>
Your array will then be accessible in params[:data] in you action
(array in this case)

So it turns out the call myArray.toJSON() only converts the javascript array myArray to a string. I have implemented a work around parse to convert the string into an array, but i was wondering if anyone knows of a JSON method to convert directly to a ruby array. Maybe this would be faster?
