JQuery implements friendly carousel image effects _ jquery

This article mainly introduces jQuery's methods and code sharing for implementing friendly carousel image effects. For more information, see:

[Processing] Here, the image is rotated and processed in a small way: When you click Page 1st in the 5th page status, the image scroll is a slide, instead of from 2-3-4-5 (this kind of multi-scroll, see Dizzy );

The implementation method is as follows:

The rest is source code sharing:

------- Css ----------------

The Code is as follows:

. Gy-slide-scroll {
Position: relative;
Width: 320px;
Height: 200px;
Overflow: hidden;
Left: 50%;
Margin-left:-160px;
}
. Gy-slide-scroll ul {
Position: absolute;
Left: 0;
Top: 0;
}
. Gy-slide-btn {
Margin-top: 10px;
Text-align: center;
Padding: 5px 0;
}
. Gy-slide-btn span,. gy-slide-btn I {
Margin-left: 5px;
Font-style: normal;
Font: 12px/1 tahoma, arial, "Hiragino Sans GB", \ 5b8b \ 4f53;
Cursor: pointer;
Border: 1px solid # ccc;
Padding: 4px 6px;
}
. Gy-slide-btn. gy-slide-cur {
Background-color: #999;
Color: # fff;
}
. Gy-slide-btn. gy-slide-no {
Color: # ccc;
Cursor: default;
}

----------- HTML ---------------------

The Code is as follows:

Homepage
Previous Page
1
2

5
Next Page
Last page

------------- JS --------------

The Code is as follows:

/* ---- Instructions for use
The structure must be consistent. Multiple calls require different IDs or class names for the outermost layer.
*/
/* ---- Parameter
@ Wrap [String] The class name or id of the outer Element
@ Auto [Boolean] If this parameter is not set, automatic playback is disabled by default. If this parameter is set to true, automatic playback is enabled.
@ Speed [Number] switch the image every several seconds. The default value is 4 seconds.
*/

The code is very concise, the effect is very good, and it is also very practical. You can use your own projects by beautifying yourself.
