Jquery tools overlay ajax ...

In this tutorial you will know how to create image gallery via ajax using jQuery tools, First we must include the library on the HEAD section of the page.

<!-- Full version of jQuery Tools + jQuery 1.3.2 -->
<script type="text/javascript" src="js/jquery.tools.min.js"></script>

Second we are going to apply styles to our overlay:
   
/* scrollable should not disable gallery navigation */
#gallery .disabled {
    visibility:visible !important;
}
#gallery .inactive {
    visibility:hidden !important;
}
/* the overlayed element */
.simple_overlay {
    /* must be initially hidden */
    display:none;
    /* place overlay on top of other elements */
    z-index:10000;
    /* styling */
    background-color:#333;
    width:675px;
    min-height:200px;
    border:1px solid #666;
    /* CSS3 styling for latest browsers */
    -moz-box-shadow:0 0 90px 5px #000;
    -webkit-box-shadow: 0 0 90px #000;
}
/* close button positioned on upper right corner */
.simple_overlay .close {
    background-image:url(images/overlay/close.png);
    position:absolute;
    right:-15px;
    top:-15px;
    cursor:pointer;
    height:35px;
    width:35px;
}
/* styling for elements inside overlay */
.simple_overlay .details {
    position:absolute;
    top:15px;
    right:15px;
    font-size:11px;
    color:#fff;
    width:150px;
}
.simple_overlay .details h3 {
    color:#aba;
    font-size:15px;
    margin:0 0 -10px 0;
}
/* "next image" and "prev image" links */
.next, .prev {
    /* absolute positioning relative to the overlay */
    position:absolute;
    top:40%;
    border:1px solid #666;
    cursor:pointer;
    display:block;
    padding:10px 20px;
    color:#fff;
    font-size:11px;
    /* upcoming CSS3 features */
    -moz-border-radius:5px;
    -webkit-border-radius:5px;
}
.prev {
    left:0;
    border-left:0;
    -moz-border-radius-topleft:0;
    -moz-border-radius-bottomleft:0;
    -webkit-border-bottom-left-radius:0;
    -webkit-border-top-left-radius:0;
}
.next {
    right:0;
    border-right:0;
    -moz-border-radius-topright:0;
    -moz-border-radius-bottomright:0;
    -webkit-border-bottom-right-radius:0;
    -webkit-border-top-right-radius:0;
}
.next:hover, .prev:hover {
    text-decoration:underline;
    background-color:#000;
}
/* when there is no next or previous link available this class is added */
.disabled {
    visibility:hidden;
}
/* the "information box" */
.info {
    position:absolute;
    bottom:0;
    left:0;
    padding:10px 15px;
    color:#fff;
    font-size:11px;
    border-top:1px solid #666;
}
.info strong {
    display:block;
}
/* progress indicator (animated gif). should be initially hidden */
.progress {
    position:absolute;
    top:45%;
    left:50%;
    display:none;
}
/* everybody should know about RGBA colors. */
.next, .prev, .info {
    background:#333 !important;
    background:rgba(0, 0, 0, 0.6) url(images/h80.png) repeat-x;
}

Now the HTML holder:
   
<!-- overlay element -->
<div class="simple_overlay" id="gallery">
<!-- "previous image" action -->
<a class="prev">prev</a>
<!-- "next image" action -->
<a class="next">next</a>
<!-- image information -->
<div class="info"></div>
<!-- load indicator (animated gif) -->
<img class="progress" src="images/ajax-loader.gif" />
<!-- end of overlay element -->
</div>

PHP Response:

Here we are going to check is how is the PHP response in order to make our Image Gallery work after an Ajax call.

   
// ************************************
// Scenario: An ajax call to this PHP script was done and
// a POST variable has been sent in order to fill $pics from
// a database.
//
// pics == array of pictures
// ************************************
// loop the array
foreach($pics as $pic)
{
    // check the class attribute --> ibox
    // $pic is also an object with certain properties in this case
       $html .= <div class="pic">
            <a href=".$pic->imgPath.$pic->strName." class="ibox" title=".$pic->strName.">
            <img src=".$pic->imgPath.$pic->strName." width="50" border="0" /></a>
            </div>;
}
//
// here I create the necessary javascript code to load the OVERLAY object of JQuery Tools
// please check the ibox call
//
$html .=
     <script type="text/javascript">
     //<![CDATA[
     $(.ibox).overlay({
            target: #gallery,
            expose: #f1f1f1
        }).gallery({
        speed: 800 });
     //]]></script>;
//
// echo response
//
echo $html;
