I have this code within a javascript function:
function load(test) {
var coordinates = new Array();
coordinates = <%= params[:coordinates] %>
}
the params contains an array with double digit numbers such as
[24,45], but when it is converted within the javascript function, it
turns into one long number, i.e. 2445. I found this by doing an
alert() with the result. I don''t really know much about javascript,
so Im not sure if this is an integer or a string or what, but
ultimately I need to get these original two digit numbers separated
and into a javascript array. I tried performing some javascript
string operations but they do not seem to be working. Any one have
any ideas here?
Thanks, Dave

there are two functions:
array_or_string_for_javascript
options_for_javascript
have a look at the source first one, it''s basically doing:
"[''#{option.join(''\'',\'''')}'']"
joining the array elements to a string

cool, yea array_or_string_for_javascript works well: var coordinates <%= array_or_string_for_javascript(params[:coordinates])%> On Sep 21, 5:22 am, Thorsten Müller <thors...-1oxKqHKwyltBDgjK7y7TUQ@public.gmane.org> wrote:> there are two functions: > array_or_string_for_javascript > options_for_javascript > > have a look at the source first one, it''s basically doing: > "[''#{option.join(''\'',\'''')}'']" > > joining the array elements to a string--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
