类似于：带有进度条的 Jquery 滑块
我有这个滑块和进度条，但我希望进度条与“上一个”和“下一个”按钮同步。因此，当您单击“下一步”时，进度条将从头开始。

$(window).load(function(){
var currentIndex = 0;// store current pane index displayed
var ePanes = $('#slider .panel'), // store panes collection
time = 3000,
bar = $('.progress_bar');
function showPane(index){// generic showPane
// hide current pane
ePanes.eq(currentIndex).stop(true, true).fadeOut();
// set current index : check in panes collection length
currentIndex = index;
if(currentIndex < 0) currentIndex = ePanes.length-1;
else if(currentIndex >= ePanes.length) currentIndex = 0;
// display pane
ePanes.eq(currentIndex).stop(true, true).fadeIn();
// menu selection
$('.nav li').removeClass('current').eq(currentIndex).addClass('current');
}
// bind ul links
$('.nav li').click(function(ev){showPane($(this).index());});
// bind previous & next links
$('.previous').click(function(){showPane(currentIndex-1);});
$('.next').click(function(){showPane(currentIndex+1);});
// apply start pane
showPane(0);
function run(){
bar.width(0);
showPane(currentIndex+1);
bar.animate({'width': "+=400"}, time, run);
}
run();
});
