Does anybody who has ever used this know how to get the slides to continue scrolling after clicking the next button? Currently if you click on 'next' button, they stay on that slide.

My jQuery skills are slightly below average and I can't figure out myself if there is an easy way of doing it. Any help would be grand :)

Easyslider is a jQuery plugin, Here is the JS:

  • The plugin code is not as useful as your own code would be. Unless you are trying to modify this code so as to use this plugin as a codebase for your own new plugin. – gilly3 Commented Sep 22, 2011 at 16:31

Reset to default 6

I got it to work by modifying the easyslider1.7.js file.

Line 195 you have

if(options.auto && dir=="next" && !clicked){
    timeout = setTimeout(function(){
       animate("next",false);
    },diff*options.speed+options.pause);
};

I added an else statement as follows

if(options.auto && dir=="next" && !clicked){
    timeout = setTimeout(function(){
        animate("next",false);
    },diff*options.speed+options.pause);
} else {
    if(clicked && options.auto && !options.numeric) {
        timeout = setTimeout(function(){
            animate("next",false);
        },diff*options.speed+options.pause);
    };
};

Might not be the most elegant solution (I'm not a javascript or jQuery expert) but it seems to work, although only for the left and right arrows, not the controls.

I was ing from a contribution from Cameron and just edit the condition (remove !clicked):

if(options.auto && dir=="next" || dir=="prev"){
    timeout = setTimeout(function(){
       animate("next",false);
    },diff*options.speed+options.pause);
};

I have the solution to auto continuous slide with numeric control:

Go to line 107 and change:

this: 

animate($("a",$(this)).attr('rel'),true);

to this: 

animate(parseInt($("a",$(this)).attr('rel')),true);

Then, add the following in line 202:

} else {    
    if(clicked && options.auto && options.numeric) {
        timeout = setTimeout(function(){
            animate("next",true);
        },diff*options.speed+options.pause);
    };
};

That fixes the problem!

Cheers!

The entire fixed code:

$.fn.easySlider = function(options){
