Jquery: turning multiple functions into one plugin

JavaScript
1

Hi,

I am learning to turn a function into a plugin. and turning a function into a plugin seems quite straight forward. But what if I have two functions correspond with each other - how can I turn these two functions into one plugin then?

such as I have these functions for making a jquery slideshow,

function run_slide(target_slide) {
	
	//add a class the the first element
	$('li:first-child',target_slide).addClass('active');
	
	//Set the opacity of all images to 0
	$('.slide li').css({opacity: 0.0});
	
	//Call the gallery function to run the slideshow, 6000 = change to next image after 6 seconds
	setInterval('loop_slide("'+target_slide+'")',5000);
}

function loop_slide(target_slide) {
	
	//Get next image, if it reached the end of the slideshow, rotate it back to the first image
	var next = ((current.next().length) ? ((current.next().hasClass('caption'))? $('.slide li:first-child') :current.next()) : $('.slide li:first-child'));	
	
	//Set the fade in effect for the next image, show class has higher z-index
	current.addClass('last-active');
	next.css({opacity: 0.0})
	.addClass('active')
	.animate({opacity: 1.0}, 1000, function(){
		current.animate({opacity: 0.0}, 1000).removeClass('active last-active');

		$('.caption p',target_slide).html(caption_description);
	});

}

this is how I call these functions,

run_slide('#slide');

ideally I would like to call these functions from the plugin method,

$('#slide').run_slide();

but how to wrap these two functions into the plugin making method below as in jquery’s documenation,

(function( $ ){
  $.fn.myPlugin = function() {
  
    // Do your awesome plugin stuff here

  };
})( jQuery );

Hope to hear from you soon.

Many thanks,
Lau
