I am trying to pass and array from an AJAX Javascript function to a
controller. The parameter is being read as a single string and not an
array.
The Javascript function:
function sendtolist(formName){
var form = $(formName)
var checked = []
checked =
form.getInputs("checkbox","plans[]").findAll(function(item)
{ return item.checked; }).pluck("value");
action="/generate_reports/advanced_plan_summary"
window.location.href=action+"?plans[]="+checked
}
The controller is:
def advanced_plan_summary
@ids = params[:plans]
@ids = @ids.split('','')
@plans = Plan.find(@ids.to_a)
if @plans[0].nil?
flash[:warning] = "Advanced Plan Selection Empty!!!"
redirect_to(:action => :index)
end
@planname = []
for plan in @plans
@planname << " " + plan.plan_name
end
flash[:notice] = "Plans picked = #{@planname}"
#...
end
I select plans with the id 58 and 32. It only seems to find the item
58???
Here is what my development log looks like:

Has anyone had experience with passing an array of objects and how
this is supposed to work.
Thanks
William

Thanks that worked for me. I would love to change this so I''m using a
link_to object ruby object to call this function and pass the results
to my controller rather than calling it from the Javascript object?
Here is how I ended up doing it
window.location.href=action+"?"+array_params(checked);
function array_params(arry) {
//Prototype magic... concatenating array onto variable string...
var paramvar = "";
arry.each(function(s){
paramvar = paramvar.concat("plans[]=",s,"&");});
paramvar = paramvar.replace(/&$/,"");
return paramvar;
}
It returned - plans[]=53&plans[]=52&plans[]=42
Thanks again.
