// Use with 2 chained functions
// The opacity of control is modified, then the control explodes before it disappears
jQuery(CELL_Square).fadeTo("opacity",0.1).effect("explode")

Remarks

Parameters of jQuery function

If a procedure ("Callback") must be passed to one of the jQuery functions, the browser procedure must be passed by reference (function name preceded by "&"). For example:
jQuery(BTN_Add).on("click", &OnAddition)

Loading the jQuery library and its extensions

A jQuery library is supplied with WEBDEV but you have to include another library in replacement or include extensions (jQuery-UI for example).
You can:
  • include the local or remote script (recommended method).
  • use the "<script src = ...> tag.
Method 1: Including the script file (local or remote (URL)) (recommended method)
  1. Display the description window of the page ("Description" from the popup menu).
  2. Select the "Advanced" tab.
  3. Select the "External resources (Javascript/CSS)" tab.
  4. To reference:
    • a remote script, copy/paste the address (URL) of the script file into the "Javascript resources" column.
    • a local script (file found on your computer for example), click the "+" button of "Javascript resources" and select the corresponding file.
Caution: Check the order of script dependencies (the jQuery library then its extensions).
Method 2: Adding the tagging for script insertion:
  1. Display the description window of the page ("Description" from the popup menu).
  2. Select the "Advanced" tab.
  3. Select the "HTML" tab.
  4. Copy the following code lines into the "HTML code added to the page header" section. For example:
    <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
    <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
Caution:
  • The code must be inserted into the "HTML code added to the page header" section and not into the "HTML code added at the end of page" section. Exception: If you want to include an extension without including another jQuery library, you must:
    • Use the method that uses the tagging.
    • Copy the code into the "HTML code added at the end of page" section.
  • This method is not recommended because the script load interrupts the page load. The loading and the page display are slowed down.
