## Requirements

* jQuery v1.3+

## Description

Displays a highly customizable tooltip when the user interacts with the matched element. As of clueTip version 1.1, this plugin is [ThemeRoller Ready][1].

* **Full documentation**: [http://plugins.learningjquery.com/cluetip/]
* **Demos**: [http://plugins.learningjquery.com/cluetip/demo/]

## Known Issues

* When `.cluetip()` is invoked from an image map `<area>` element, the plugin ignores the `postionBy` option. Positioning the tooltip by the `coords` is beyond the scope of the plugin, so it instead falls back to positioning according to the mouse's position (`event.pageX` and `event.pageY`) when it enters the `<area>`.

## Important clueTip 1.2 Change

Version 1.2 of the clueTip plugin changes the HTML structure of the tooltip. It uses classes instead of IDs for the elements within the clueTip. This allows multiple tooltips to be visible at the same time (one per call to the .cluetip() method) if the `multiple` option is set to `true`.

The plugin may not work as expected if you update jquery.cluetip.js to version 1.2+ and you don't also update the jquery.cluetip.css stylesheet.

If you have a lot invested in the old clueTip's structure with the IDs, you can get it back by:

1. adding the jquery.compat.cluetip.js file immediately after jquery.cluetip.js, AND
2. replacing jquery.cluetip.css with jquery.compat.cluetip.css.

## Features

### Options

The clueTip plugin allows for (too?) many options. For a complete list, check out the [plugin's homepage][2]

### Content via ajax

By default, the clueTip plugin loads a page indicated by the "rel" attribute via ajax and displays its contents. However, *the attribute to be used for both the body and the heading of the clueTip is user-configurable*.
If a "title" attribute is specified, its value is used as the clueTip's heading.

### Content from HTML element

Optionally, the clueTip's body can display content from an element on the same page.

Just indicate the element's id (e.g. "#some-id") in the rel attribute.

### Content from title attribute

Optionally, the clueTip's body can display content from the title attribute, when a delimiter is indicated.

* The string before the first instance of the delimiter is set as the clueTip's heading.
* All subsequent strings are wrapped in separate DIVs and placed in the clueTip's body.

## Examples

### Basic

This is the most basic clueTip. It displays a 275px-wide clueTip on mouseover of the element with an ID of "tip." On mouseout of the element, the clueTip is hidden.

```javascript
$('#tip).cluetip();
```

### Setting Multiple Options
The following displays a clueTip on mouseover of all `<a>` elements with class="clue". The hovered element gets a class of "highlight" added to it (so that it can be styled appropriately. This may be useful for non-anchor elements in older browsers such as IE6.). The clueTip is "sticky," which means that it will not be hidden until the user either clicks on its "close" text/graphic or displays another clueTip. The "close" text/graphic is set to display at the bottom of the clueTip (default is top) and display an image rather than the default "Close" text. Moreover, the body of the clueTip is truncated to the first 60 characters, which are followed by an ellipsis (...). Finally, the clueTip retrieves the content with a `POST` request rather than the default `GET`.

```javascript
$('a.clue').cluetip({
  hoverClass: 'highlight',
  sticky: true,
  closePosition: 'bottom',
  closeText: '<img src="cross.png" alt="close" />',
  truncate: 60,
  ajaxSettings: {
    type: 'POST'
  }
});
```

### Triggering the `hideCluetip` event (useful for touch devices)

You can programmatically hide (close) a clueTip by triggering the "hideCluetip" custom event. On a touch-enabled device, for example, you could hide any visible clueTips when the user touches anywhere in the body except on a link or on the clueTip itself:

```javascript
$('body').bind('touchstart', function(event) {
 event = event.originalEvent;
 var tgt = event.touches[0] && event.touches[0].target,
     $tgt = $(tgt);

 if (tgt.nodeName !== 'A' && !$tgt.closest('div.cluetip').length ) {
   $(document).trigger('hideCluetip');
 }
});
```
