Class: Spinner {#Spinner}

Adds a semi-transparent overlay over a DOM element with a 'spinning' ajax icon.

Extends

Implements

Spinner Method: constructor

Syntax

new Spinner(target[, options]);

Arguments

  1. target - (mixed) A string of the id for an Element or an Element reference to overlay; defaults to document.body
  2. options - (object) a key/value set of options

Options

  • all of Mask options PLUS:
  • message - (mixed, optional) message placed above the spinner image (as in "Please wait..."). Can be a string or an element.
  • class - (string) css class name to apply to the spinner container.
  • containerPosition - (object) options passed to Element:position for the container of the message; relativeTo is set to the target in the arguments automatically (but can be overwritten).
  • content - (object) properties for the element that contains the spinning image and the message. Defaults only to "class:spinner-content".
  • img - (object or false) properties for the image element (note: not an img tag - a div); if set to false no image will be injected. Defaults to "class:spinner-img".
  • fxOptions - (object) options passed to the effects used to transition the overlay and the image opacity.

Styles

You can style the layer and its contents by just defining a css style for the class names specified in the options class name (these default to ".spinner", ".spinner-content", and ".spinner-img"). You can download the default styles and spinner image here: spinner.css, spinner.gif. Without any styles nothing will show up, except for any optional message you may have passed.

Events

  • show - (function) callback to execute when the spinning layer is shown; passed the target element to which the Spinner was attached
  • hide - (function) callback to execute when the spinning layer is hidden; passed the target element to which the Spinner was attached

Example

<div id="myElement">...</div>

new Spinner('myElement');

Spinner Method: toggle {#Spinner:toggle}

Toggles the Spinner visibility. If the Spinner is currently visible, it will hide. Otherwise it will display.

Syntax

mySpinner.toggle(element);

Arguments

  1. element - (mixed, optional) A string of the id for an Element or an Element reference to overlay; defaults to the target passed in at initialization, but you can specify a different element if you wish to reuse the class.

Returns

  • (object) This instance of Spinner

Spinner Method: show {#Spinner:show}

Displays the Spinner layer.

Syntax

mySpinner.show(noFx);

Arguments

  1. noFx - (boolean) if true the spinner will not use effects to display but will show immediately (defaults to false).

Returns

  • (object) This instance of Spinner

Spinner Method: hide {#Spinner:hide}

Hides the Spinner layer.

Syntax

mySpinner.hide(noFx);

Returns

  1. noFx - (boolean) if true the spinner will not use effects to hide but will hide immediately (defaults to false).

Spinner Method: destroy {#Spinner:destroy}

Destroys the Spinner spinner layer and its contents. This renders the instance of this class inert (and further calls to its methods will throw errors).

Syntax

mySpinner.destroy()

Returns

  • (object) This instance of Spinner

Spinner Method: position {#Spinner:position}

Reasserts the position of the spinner layer and its contents.

Syntax

mySpinner.position()

Returns

  • (object) This instance of Spinner

Spinner Method: resize {#Spinner:resize}

Reasserts the dimensions of the overlay layer. Note that this method is called when [Spinner.position][] is called, so you needn't call it if you call position.

Syntax

mySpinner.destroy()

Returns

  • (object) This instance of Spinner

Class: Request {#Request}

Extends Request to add integrated Spinner functionality.

Extends

Syntax

new Request(options);

Arguments

  • options - (object) an object with key/value options

Options

  • all of Request options PLUS:
  • useSpinner - (boolean) use the Spinner class with this request
  • spinnerOptions - (object) the options object for the Spinner class
  • spinnerTarget - (mixed) a string of the id for an Element or an Element reference to use instead of the one specifed in the update option. This is useful if you want to overlay a different area (or, say, the parent of the one being updated).

Example

new Request({
    url: '/myHtmlFragment.html',
    update: $('myElement'),
    useSpinner: true,
    spinnerOptions: {...etc...}
});
