Slider initialization

http://www.pearlfisher.com/ uses the Noobslider slideshow component. If you look carefully when you load the page, you'll see the first image slide into view. The big question is: how?

The start index is 0 and animation.next() is called. Nonetheless, the first image hoves into view. What *was* showing before that happened?

This is a difficult question and a precise and full answer will get maximum points and starry accolades, despite starting at 200 points

You can try to add an additional parameter say startIndex to the script. That you can initialize as other parameters eg. startIndex : 1

In the js file you can add it like
initialize: function(params){
.......
this.startIndex= params.startIndex || 0;
.......
},

In the next and previous functions you can try to replace 0 (default) with startIndex

You may also need to change it at some other places.

so with this if you do not initialize startIndex then it will work as normal ( 0 being the default). else it should take the parameter and should skip the elements.

Hope this helps

There is a blank element which is being treated as element 0

<span><img src="images/cases/initial.jpg" alt="" /></span>

The source of the image is initial.jpg which is blank image so virtually nothing will appear while the page loads.

Now the script will be executed only after the body is loaded completely.

window.addEvent('domready',function(){

Start element in this is 0 which is the blank image in the span above. the call to animation.next(); is below the call to the slider so it will execute the next() function and the second element (idspan0) will be loaded and displayed on screen.

Hope this helps.

ddsh79, that's a promising start, but if initial.jpg is the initial image, how is it that it gets left out of the slideshow thereafter (it's not possible to return to it with the slider nav buttons)?

The answer to this lies in slider.js file. If you look at it you'll find the code

var initial_animate1 = function(){
                            animation.walk(0,manual);
                        };

                        var initial_animate2 = function(){
                            animation.next();
                        };

                        initial_animate.chain(initial_animate1);
                        initial_animate.chain(initial_animate2);

see initial animate makes it to walk to element 0 which is the blank image but just after that there is a call to initial_animate2 function which calls animation.next(); making it to load the next iimage.

This function is called when the animation reaches at the end of the slide and next is clicked again.

I have not looked for the previous functionality but it should also be bypassing the 0th element (blank image).

Yes, that pretty nasty and tortuous. What i'm actually using is the attached so i'll try to find a means of skipping the item at index 0 that's simple an elegant. Any suggestions?
