This example is written by me once, hoping to help you and learn together. Effect:

The html code is as follows:

Copy codeThe Code is as follows:
<Html xmlns = "http://www.w3.org/1999/xhtml" xml: lang = "en" lang = "en">
<Head>
<Title> Image Browsing tool creation </title>
<Script type = "text/javascript" src = "js/main. js"> </script>
<Link rel = "stylesheet" type = "text/css" href = "style/css.css">
</Head>
<Body>
<Div id = "pic_browser">


<Div class = "mask3" onclick = "javascript: jzk. ui. moveImg (3);"> </div> <! -- Adds a three-level mask -->


<Div class = "mask2" onclick = "javascript: jzk. ui. moveImg (2);"> </div> <! -- Adds a secondary mask -->


<Div class = "mask1" onclick = "javascript: jzk. ui. moveImg (1);"> </div> <! -- Adds a level-1 mask -->


<Div class = "mask5" onclick = "javascript: jzk. ui. moveImg (-1);"> </div> <! -- Same effect as mask1 -->


<Div class = "mask6" onclick = "javascript: jzk. ui. moveImg (-2);"> </div> <! -- Same effect as mask2 -->


<Div class = "mask7" onclick = "javascript: jzk. ui. moveImg (-3);"> </div> <! -- Same effect as mask3 -->


</Div>
</Body>
</Html>

The css code is as follows:

Here mask1, 2, 3... is a div that covers several photos. The opacity attribute is used to define transparency, which can realize a sense of opacity and make the appearance more beautiful.

Copy codeThe Code is as follows:
Body {width: 1340px; height: 500px; background: url (../images/body_bg.gif) no-repeat ;}
# Pic_browser {width: 860px; height: 192px; position: relative; margin: 130px pixel ;}
# Pic_browser img {position: absolute; border: none ;}

. Prev {top: 76px; left: 0px ;}
# Img1,. mask3 {width: pixel PX; height: 70px; left: 45px; top: 61px; z-index: 4 ;}
# Img2,. mask2 {width: 166px; height: 110px; left: 95px; top: 41px; z-index: 5 ;}
# Img3,. mask1 {width: 226px; height: 150px; left: 175px; top: 21px; z-index: 6 ;}
# Img4 {width: 290px; height: 192px; left: 285px; top: 0px; z-index: 7 ;}
# Img5,. mask5 {width: 226px; height: 150px; right: 175px; top: 21px; z-index: 6 ;}
# Img6,. mask6 {width: 166px; height: 110px; right: 95px; top: 41px; z-index: 5 ;}
# Img7,. mask7 {width: pixel PX; height: 70px; right: 45px; top: 61px; z-index: 4 ;}
. Next {top: 76px; right: 0px ;}

. Mask1,. mask2,. mask3,. mask5,. mask6,. mask7 {background: # fff; position: absolute ;}
. Mask1,. mask5 {opacity: 0.3 ;}
. Mask2,. mask6 {opacity: 0.5 ;}
. Mask3,. mask7 {opacity: 0.7 ;}

The js Code is as follows:

Copy codeThe Code is as follows:
Window. onload = function ()
{
Jzk. app. initImg ();
}

Var imgArray = new Array ();
ImgArray [0] = 'images/1.jpg ';
ImgArray [1] = 'images/2.jpg ';
ImgArray [2] = 'images/3.jpg ';
ImgArray [3] = 'images/4.jpg ';
ImgArray [4] = 'images/5.jpg ';
ImgArray [5] = 'images/6.jpg ';
ImgArray [6] = 'images/7.jpg ';
Var base = 0;

Var jzk ={};/* defines the namespace */

Jzk. tools ={};/* layer first layer */

Jzk. ui ={};/* Layer 2 */
Jzk. ui. moveImg = function (offset)
{
Base = (base-offset );
For (var I = base; I <base + 7; I ++)/* defines I as the variable under the array */
{
Var img = document. getElementById ('img '+ (I-base + 1);/* Ensure that the img variable is img1, img2, img3... until the seven img elements of img7 */
If (I <0)/* array subscript I <0, indicating offset> 0 ,*/
{
Img. src = imgArray [imgArray. length + I];
}
Else if (I> imgArray. length-1)
{
Img. src = imgArray [i-imgArray.length];
}
Else
{
Img. src = imgArray [I];
}
}
}

Jzk. app ={};/* Layer 3 */
Jzk. app. initImg = function ()/* initialize the display image, that is, call the moveImg function process: parameter 7, base equals-7, I equals-7,-6,-5, -4,-3,-2,-1. The corresponding elements are img1, img2 ,... img7, so there are: img1 = imgArray [-7 + 7], img2 = imgArray [-6 + 7]... */
{
Jzk. ui. moveImg (7);/* The initial parameter should be set to the number of visible sheets (7 in this example );*/
}
It is difficult to understand the js Code of the three files. I have also provided detailed comments above. If anyone else does not understand the comments, they can be discussed in the following comments.
