I am very new to JavaScript and only have
the most basic understanding of how it works, so please bear with me. :) I'm using
the jquery.innerfade.js script to create a slideshow with fade transitions for a website I'm developing, and I have added navigation buttons (which are set as background-images) that navigate between
the “slides”.
The navigation buttons have three states: default/off, hover, and on (each state is a separate image). I created a separate JavaScript document to set
the buttons to “on” when they are clicked.
The “hover” state is achieved through
the CSS.
Both
the slideshow and
the navigation buttons work well. There is just one thing I want to add: I would like
the appropriate navigation button to display as “on” while
the related “slide” is “playing”.
Here's
the HTML:
<div id="mainFeature">
<ul id="theFeature">
<li id="the1feature"><a href="#" name="#promo1"><img src="_images/carousel/promo1.jpg" /></a></li>
<li id="the2feature"><a href="#" name="#promo2"><img src="_images/carousel/promo2.jpg" /></a></li>
<li id="the3feature"><a href="#" name="#promo3"><img src="_images/carousel/promo3.jpg" /></a></li>
</ul>
<div id="promonav-con">
<div id="primarypromonav">
<ul class="links">
<li id="the1title" class="promotop"><a rel="1" href="#promo1" class="promo1" id="promo1" onMouseDown="promo1on()"><strong>Botox Cosmetic</strong></a></li>
<li id="the2title" class="promotop"><a rel="2" href="#promo2" class="promo2" id="promo2" onMouseDown="promo2on()"><strong>Promo 2</strong></a></li>
<li id="the3title" class="promotop"><a rel="3" href="#promo3" class="promo3" id="promo3" onMouseDown="promo3on()"><strong>Promo 3</strong></a></li>
</ul>
</div>
</div>
And here is
the jquery.innerfade.js, with my changes:
(function($) {
$.fn.innerfade = function(options) {
return this.each(function() {
$.innerfade(this, options);
});
};
$.innerfade = function(container, options) {
var settings = {
'speed': 'normal',
'timeout': 2000,
'containerheight': 'auto',
'runningclass': 'innerfade',
'children': null
};
if (options)
$.extend(settings, options);
if (settings.children === null)
var elements = $(container).children();
else
var elements = $(container).children(settings.children);
if (elements.length > 1) {
$(container).css('position', 'relative').css('height', settings.containerheight).addClass(settings.runningclass);
for (var i = 0; i < elements.length; i++) {
$(elements[i]).css('z-index', String(elements.length-i)).css('position', 'absolute').hide();
};
this.ifchanger = setTimeout(function() {
$.innerfade.next(elements, settings, 1, 0);
}, settings.timeout);
$(elements[0]).show();
}
};
$.innerfade.next = function(elements, settings, current, last) {
$(elements[last]).fadeOut(settings.speed);
$(elements[current]).fadeIn(settings.speed, function() {
removeFilter($(this)[0]);
});
if ((current + 1) < elements.length) {
current = current + 1;
last = current - 1;
} else {
current = 0;
last = elements.length - 1;
}
this.ifchanger = setTimeout((function() {
$.innerfade.next(elements, settings, current, last);
}), settings.timeout);
};
})(jQuery);
// **** remove Opacity-Filter in ie ****
function removeFilter(element) {
if(element.style.removeAttribute){
element.style.removeAttribute('filter');
}
}
jQuery(document).ready(function() {
jQuery('ul#theFeature').innerfade({
speed: 1000,
timeout: 7000,
containerheight: '291px'
});
// jQuery('#mainFeature .links').children('li').children('a').attr('href', 'javascript:void(0);');
jQuery('#mainFeature .links').children('li').children('a').click(function() {
clearTimeout(jQuery.innerfade.ifchanger);
for(i=1;i<5;i++) {
jQuery('#the'+i+'feature').css("display", "none");
//jQuery('#the'+i+'title').children('a').css("background-color","#226478");
}
// if(the_widths[(jQuery(this).attr('rel')-1)]==960) {
// jQuery("#vic").hide();
// } else {
// jQuery("#vic").show();
// }
// jQuery('#the'+(jQuery(this).attr('rel'))+'title').css("background-color", "#286a7f");
jQuery('#the'+(jQuery(this).attr('rel'))+'feature').css("display", "block");
clearTimeout(jQuery.innerfade.ifchanger);
});
});
And
the separate JavaScript that I created:
function promo1on() {document.getElementById("promo1").className="promo1on"; document.getElementById("promo2").className="promo2"; document.getElementById("promo2").className="promo2"; }
function promo2on() {document.getElementById("promo2").className="promo2on"; document.getElementById("promo1").className="promo1"; document.getElementById("promo3").className="promo3"; }
function promo3on() {document.getElementById("promo3").className="promo3on"; document.getElementById("promo1").className="promo1"; document.getElementById("promo2").className="promo2"; }
And, finally,
the CSS:
#mainFeature {float: left; width: 672px; height: 290px; margin: 0 0 9px 0; list-style: none;}
#mainFeature li {list-style: none;}
#mainFeature #theFeature {margin: 0; padding: 0; position: relative;}
#mainFeature #theFeature li {position: absolute; top: 0; left: 0;}
#promonav-con {width: 463px; height: 26px; padding: 0; margin: 0; position: absolute; z-index: 900; top: 407px; left: 283px;}
#primarypromonav {padding: 0; margin: 0;}
#mainFeature .links {padding: 0; margin: 0; list-style: none; position: relative; font-family: arial, verdana, sans-serif; width: 463px; height: 26px;}
#mainFeature .links li.promotop {list-style: none; display: block; float: left; display: inline; margin: 0; padding: 0;}
#mainFeature .links li a {display: block; float: left; display: inline; height: 26px; text-decoration: none; margin: 0; padding: 0; cursor: pointer;}
#mainFeature .links li a strong {margin-left: -9999px;}
#mainFeature .links li a.promo1 {background: url(../_images/carouselnav/promo1.gif); width: 155px;}
#mainFeature .links li:hover a.promo1 {background: url(../_images/carouselnav/promo1_hover.gif); width: 155px;}
#mainFeature .links li a.promo1:hover {background: url(../_images/carouselnav/promo1_hover.gif); width: 155px;}
.promo1on {background: url(../_images/carouselnav/promo1_on.gif); width: 155px;}
#mainFeature .links li a.promo2 {background: url(../_images/carouselnav/promo2.gif); width: 153px;}
#mainFeature .links li:hover a.promo2 {background: url(../_images/carouselnav/promo2_hover.gif); width: 153px;}
#mainFeature .links li a.promo2:hover {background: url(../_images/carouselnav/promo2_hover.gif); width: 153px;}
.promo2on {background: url(../_images/carouselnav/promo2_on.gif); width: 153px;}
#mainFeature .links li a.promo3 {background: url(../_images/carouselnav/promo3.gif); width: 155px;}
#mainFeature .links li:hover a.promo3 {background: url(../_images/carouselnav/promo3_hover.gif); width: 155px;}
#mainFeature .links li a.promo3:hover {background: url(../_images/carouselnav/promo3_hover.gif); width: 155px;}
.promo3on {background: url(../_images/carouselnav/promo3_on.gif); width: 155px;}
Hopefully this makes sense! Again, I'm very new to JavaScript/JQuery, so I apologize if this is a mess. I'm very grateful for any suggestions. Thanks!
