Hi,
I want to add a tag-search to my page. The tags can be given to each
item by clicking a checkbox. The value of the checkboxes is saved in the
table using the check_box_tag.
By editing the tags of an item (refreshing the page) the checkboxes
delete their status - reset theirselves.
Question:
How can I check if a box was clicked last time(value saved in the table)
into the blue:
if "value" exists in "table"
document.getElementById("checkbox1").checked = true
if "value" doesn''t exist in "table"
document.getElementById("checkbox1").checked = false
Thx for your answers

It is not quite clear what you are trying to do. But it seems like you are reinventing a square wheel :) Did you try some ready solutions like http://github.com/mbleigh/acts-as-taggable-on/ ?

I tried and tried and tried ... but everything in my checkbox is deleted after refreshing the page (instead of the values in my database) so how can I ask for them. Thx till now... -- Posted via http://www.ruby-forum.com/.

This is what users expect. Why do you need this functionality, anyway? If you explain what you''re trying to achieve by doing this, perhaps we can be of more help.> > Thx till now...Best, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/.
