jquery-bubble-text

This plugin introduces one animated way of changing text.

• Examples
• Properties
• Methods

Examples

1. Fading letters. (jsFiddle)
2. Looping phrases. (jsFiddle)

Properties

Mandatory: element, and newText.

There are only two properties you must supply, so it can work:

var properties = {     element: $element,     newText: 'new Text', }; bubbleText(properties);

• properties.element is the DOM node in which the animation will occur and must be a leaf one (without children) because spans will run inside it during animation phase.
• properties.newText must be a string.

Below you can see the optional properties:

speed

The default speed from start till the end is 2000 miliseconds, you can change it this way:

properties.speed = 3500;  // 3.5 seconds

letterSpeed

This property has priority over properties.speed. If you choose setting letterSpeed, the total time of the animations will be proportional to its old and new text lengths.

properties.letterSpeed = 50;  // miliseconds

callback

You can execute a function after the animation is completed:

properties.callback = function() {     console.log('finished'); };

proportional

The proportional property is set true by default, if the initial text is "abcd" and the new text is "ef", the animation will be:

1. remove "a",
2. remove "b",
3. add "e",
4. remove "c",
5. remove "d",
6. add "f".

But some may prefer steps of 1 remotion and 1 addition:

1. remove "a",
2. add "e",
3. remove "b",
4. add "f".
5. remove "c",
6. remove "d",

For that purpose you can use:

properties.proportional = false;

repeat

The repeat action is 0, by default it runs the animation only once. But you can repeat one animation again and again if you want so:

properties.repeat = 2;

Since Infinity - 1 results Infinity, you can do an endless animation with:

properties.repeat = Infinity;

timeBetweenRepeat

The previous repeat property has a default delay of 1.5 seconds before starting again, but you can change it:

properties.timeBetweenRepeat = 500;  // 0.5 seconds

Methods

The bubbleText function returns an instance control to you:

var ctrl = bubbleText(options);

This instance have three methods you can use:

restart

If you don't want to wait the end of the animation to restart with repeat or callback, you can use:

ctrl.restart();

This method:

• will instantly set the old text back;
• will do the animation again.

finish

If for some strange weird reason you need to finish the animation in a shot, you can use:

ctrl.finish();

This method:

• will instantly set the new text to the $element (without spans);
• will not restart the animation even with properties.repeat on;
• accepts a boolean argument (when true will run the properties.callback function).

stop

If for some other strange weird reason you need to stop the animation, you can use:

ctrl.stop();

This method:

• will stop the spans immediately;
• will not remove the spans;
• will not trigger properties.callback.

You are able to call ctrl.restart or ctrl.finish after ctrl.stop().

Happy coding

That's it !! Thanks for your interest :)
