jQuery Simple Popup Rect Window

Written by Garry Lachman (Admin). Filed under jQuery. Tagged , , , , , , , , , , , . .

Hi,
I wrote a light and simple popup rect window with auto resize mode and buttons.

Popup Options

  • width, height = size of window
  • top, left = position in px set 0 set center
  • send_button = show send button
  • send_button_caption = send button caption
  • send_button_disabled = disbale send button
  • cancel_button = show cancel button
  • cancel_button_caption = disable cancel button

Popup Public Methods

  • enable_auto_resize = enable auto resize mode by content, for auto resize use Ben Alman jQuery resize
    event plugin from here: http://benalman.com/projects/jquery-resize-plugin/
  • change_height = change height (height in px, is using transcation)
  • set_content = send html content
  • get_content = get content rect
  • disbaled = disable and enable popup
  • send_button_disabled = disable and enable send button
  • add_click_event = add event to send and cancel buttons
  • close = close window
