If you need to add dynamically more elements to a nested_forms with Rails you might find this plugin useful. I've got to do this so many times in so many projects that i finally decided to make it a plugin.
Klonen changes the attributes for for <label>, name for <input> and id for <li>, <input>, <label>, <select> and <textarea>. I included <li> elements because the project i'm working on right now uses formtastic.
You only have to choose the element that you want to clone and pass a settings parameter.
$("#element-to-clone").klonen({});
addLink:The text for the Add more link.removeLink:The text for the remove more link.insertAfter:Where you want to put the div containing the add/remove links.getLength:The selector that you want to use as a counter.toRemove:Elements you want to remove from the cloned element.
- Generate dynamic ids for the links.
- To make
<img>links. - Fix the error on loading.
