OverText Method: constructor

Syntax

new OverText(input[, options]);

Arguments

1. input - (mixed) a DOM Element (or its id) that should receive the hover text
2. options - (object, optional) a key/value set of options

Options

• element - (string) type of element to be used for the OverText; defaults to label.
• positionOptions - (object) data passed to Element.position.
• poll - (boolean) whether to periodically re-evaluate the input to set their overtext element's position and visibility (useful for login in fields that are often populated by remembered usernames and passwords by the browser); defaults to false.
• pollInterval - (number) the duration between polling in milliseconds; defaults to 250.
• wrap - (boolean) if true, all inputs are wrapped with a div that is positioned relatively with the class "overTxtWrapper"
• textOverride - (string) if defined, this will be the value of the over text rather than the input alt or title.
• labelClass - (string, defaults to overTxtLabel) a css classname to style the input overtext

Events

• onTextHide - (function) callback fired when an overtext element is hidden (passed the overtext element and the input element as arguments)
• onTextShow - (function) callback fired when an overtext element is shown (passed the overtext element and the input element as arguments)

Note

OverText positions the text over your input. Depending on your layout, it's possible that your input might move (for instance, if you inject new content above it, or the user resizes their browser). This often happens with Form.Validator.Inline, for instance. The solution here is to wrap your inputs in containers that are positioned (position: relative, for instance). By wrapping your inputs, when the page flow changes the overtext will move with them. The wrap option does this for you automatically.

OverText Method: hide

Hides the overtext element for a given input.

Syntax

myOverText.hide();

Returns

• (object) - This instance of OverText

OverText Method: show

Shows the overtext element for a given input.

Syntax

myOverText.show();

Returns

• (object) - This instance of OverText

OverText Method: focus

Focuses the input and hides the overtext.

Returns

• (object) - This instance of OverText

OverText Method: enable

Enables the behavior of the class. Displays the text hint if the input is empty.

Returns

• (object) - This instance of OverText

OverText Method: disable

Disables the behavior of the class. Hides the text hint.

Returns

• (object) - This instance of OverText

OverText Method: destroy

Destroys the class, removing the behavior from the input as well as any DOM elements created (the hint text label and the wrapper element if the options called for it).

Returns

• (object) - This instance of OverText

OverText Method: reposition

Repositions the overtext element over a the input.

Syntax

myOverText.reposition();

Returns

• (object) - This instance of OverText

OverText Method: startPolling

Begins repeatedly polling the input to position and show (or hide) the over text. Useful for login fields that are often autofilled by browsers.

Returns

• (object) - This instance of OverText

OverText Method: stopPolling

Cancels the polling of the input.

Returns

• (object) - This instance of OverText

OverText Static Methods: update

These method calls are made against the OverText namespace (not instances of OverText) and apply their actions to all running instances.

OverText Static Method: update

This allows you to manually re-assert the positioning and visibility of all the OverTexts on the page.

Syntax

OverText.update();

Note

This method is NOT a method on the instance. Rather it is on the namespace. So:

Example

var myOverText_1 = new OverText(...);
var myOverText_2 = new OverText(...);
//...later
OverText.update(); //updates all the instances of OverText

Returns

• array - an array of all the running instances of the class.

OverText Static Method: hideAll

This allows you to manually hide all the OverTexts on the page.

Syntax

OverText.hideAll();

Note

This method is NOT a method on the instance. Rather it is on the namespace. So:

Example

var myOverText_1 = new OverText(...);
var myOverText_2 = new OverText(...);
//...later
OverText.hideAll(); //hides all the instances of OverText

Returns

• array - an array of all the running instances of the class.

OverText Static Method: showAll

This allows you to manually show all the OverTexts on the page.

Syntax

OverText.showAll();

Note

This method is NOT a method on the instance. Rather it is on the namespace. So:

Example

var myOverText_1 = new OverText(...);
var myOverText_2 = new OverText(...);
//...later
OverText.showAll(); //updates all the instances of OverText

Returns

• array - an array of all the running instances of the class.

Type: Element

Extends the Element Type with a reference to its OverText instance.

Element property: OverText

Syntax

myInput.retrieve('OverText'); //the instance of OverText for the element
