drop_receiving_element

Makes the element with the DOM ID specified by element_id receive dropped draggable elements (created by draggable_element). and make an AJAX call. By default, the action called gets the DOM ID of the element as parameter.

Example:

<%= drop_receiving_element("my_cart", :url =>
  { :controller => "cart", :action => "add" }) %>

You can change the behaviour with various options, see http://script.aculo.us for more documentation.

Some of these options include:

• :accept - Set this to a string or an array of strings describing the allowable CSS classes that the draggable_element must have in order to be accepted by this drop_receiving_element.

• :confirm - Adds a confirmation dialog. Example:

  :confirm => "Are you sure you want to do this?"
  

• :hoverclass - If set, the drop_receiving_element will have this additional CSS class when an accepted draggable_element is hovered over it.

• :onDrop - Called when a draggable_element is dropped onto this element. Override this callback with a JavaScript expression to change the default drop behaviour. Example:

  :onDrop => "function(draggable_element, droppable_element, event) { alert('I like bananas') }"
  

  This callback gets three parameters: The Draggable element, the Droppable element and the Event object. You can extract additional information about the drop - like if the Ctrl or Shift keys were pressed - from the Event object.

• :with - A JavaScript expression specifying the parameters for the XMLHttpRequest. Any expressions should return a valid URL query string.
