Here's an overview of the whole process:

1, hide all the pictures except the first one

2. Get the alt information of the first picture and display it in the information bar, and add a click event

1 2 3 4 5 6

CSS section:

# banner {position:relative; width:280px; height:160px; border:1px solid # 666; overflow:hidden;} # banner ul {width:138px; height:18px;position:absolute;list-style-type:none;filter: Alpha (Opacity=80); opacity:0.8;z-index:1002; margin:0; padding:0; bottom:3px; right:5px; line-height: 18px; text-align: center;} # banner ul li {width: 18px; height:18px; margin:0px 2px Color:#FFF; border:#e5eaff 1px solid;background:#6C6D6E;cursor:pointer} # banner ul li.on {background:#900} # banner ul li a {color: white;} # banner ul li a:hover {text-decoration: none;} # banner_list a {position:absolute;} # banner_list {position:absolute; right: 5px; bottom: 5px;}

JS section:

Var t = n = 0, count; $(document) .ready (function () {count=$ ("# banner_list a"). Length; $("# banner_list a:not (: first-child)"). Hide (); $("# banner_info"). Html ($("# banner_list a:first-child"). Find ("img"). Attr ('alt')) ("# banner_info") .click (function () {window.open ($("# banner_list a:first-child"). Attr ('href'), "_ blank")}); $("# banner li") .click (function () {var I = $(this). Text ()-1 function / get the value within the Li element, that is, 1, 2, 3, 4 n = I; if (I > = count) return $("# banner_info") .html ($("# banner_list a") .eq (I) .find ("img") .attr ('alt')) $("# banner_info"). Unbind (). Click (function () {window.open ($("# banner_list a") .eq (I) .attr ('href'), "_ blank")}) $("# banner_list a"). Filter (": visible"). FadeOut (500). Parent (). Children (). Eq (I) .fadein (1000); document.getElementById ("banner"). Style.background= "; $(this) .toggleClass (" on ") $(this). Siblings (). RemoveAttr ("class"); t = setInterval ("showAuto ()", 4000); $("# banner") .hover (function () {clearInterval (t)}, function () {t = setInterval ("showAuto ()", 4000);}) function showAuto () {n = n > = (count-1)? 0: + n; $("# banner li") .eq (n) .trigger ('click') } the above is the content of this article on "how to use JQuery code to achieve picture rotation effect".
