modo.Image

A image object, enhanced by modo methods. Can - for example - be used inside a modo.FormContainer to display user avatars.

Constructor

modo.Image(params)modo.Image

The following list of parameters can be used in the params object, passed to the constructor. Parameters in [brackets] are optional.

PropertyDescription

[value]

The URL of the image to be loaded.

[model]

A Backbone Model you want to bind the Element to.

[modelKey]

The key of the Backbone Model to be observed on changes. Required when the model property is set.

[className]

A string with custom CSS classes to apply to the generated DOM element

[dataAttributes]

A object with attributes to assign to the generated DOM element. Omit the "data-" part. So for example {count: 1} becomes data-count="1" on the DOM element.

The jQuery enhanced DOM element to be generated. If nothing is set, a standard DIV container will be created. If you want to use a different DOM element, pass a jQuery generated DOM element to this parameter.

[showEffect]

The default show effect for the element. See associated property description. Default: null

[hideEffect]

The default hide effect for the element. See associated property description. Default: null

Properties

Inherited Properties from modo.Element

elObject

Contains the jQuery enhanced DOM Node of this modoJS element.

modoIdNumber

Contains a internally given, numeric ID for this element.

visibleBool

Will be set by .show() and .hide(). Access this property to check the current visibility of the element.

showEffectobject

Set a default show effect (like the options you can pass to the show() / hide() methods.

Example:

element.showEffect = {
    effect: 'slideDown',
    effectArgs: ['fast']
};

hideEffectobject

Define a default hide effect instead of a simple, instant hide.

Methods

enable()this

Enables the button to capture clicks. Removes the CSS-Class mdo-disabled from its DOM element. Triggers the Backbone Event "enabled".

disable()this

Disables the button to not capture any clicks. Adds the CSS-Class mdo-disabled to its DOM element. Triggers the Backbone Event "disabled".

set(value)this

Pass true or false here to change the elements value manually. If the element is bound to a model, the models property will be changed as well.

setBlank()this

Sets the image src to a transparent image of 1x1 pixel size through a base64 data url.
Taken from the blog post The smallest transparent pixel.

get()boolean

Returns the current value.

Inherited Methods from modo.Element

setFlexible([value])this

Pass either true or false to this value to make the element stretch inside a modo.FlexContainer element.

show(options)this

Make the connected DOM object visible and trigger the Backbone Event "show".

You can control the way the element is shown by passing an object of options.

Example:

element.show({
    effect: 'slideDown',
    effectArgs: ['fast']
});

hide()this

Make the connected DOM object invisible and trigger the Backbone Event "hide".

You can control the hide effect the same way as with the show() method.

addClass(classname, doPrefix)this

Will add another class name to the DOM element. The class name will be automatically prefixed (i.e. with mdo-) if doPrefix = true (default).

removeClass(classname, doPrefix)this

Will remove a class name from the DOM element. The class name will be automatically prefixed.

addClassTemporary(classname, timeout, doPrefix)this

Helps with adding a classname temporarily to the object. Just call this method and after the specified amount of time, the added class(es) will be removed.


Note: All modoJS Objects are extended with all methods of the Backbone.Events class.
