phpcms实现轮播的方法:首先在想要加轮播图的位置加入“<div id="flowDiagram" >...</div>”;然后根据自己的需求对css样式进行更改;最后在需要实现轮播的地方加入js代码即可。
phpcms首页实现轮播图
1.在你想要加轮播图的位置加入以下
<div id="flowDiagram" > <div id="button"> <span index="1" class="on"></span> <span index="2"></span> <span index="3"></span> <span index="4"></span> <span index="5"></span> </div> <div id="photo" style="left:-1200px;"> <div> {pc:content action="position" posid="1" thumb="1" order="listorder DESC" num="5"} {loop $data $r} <div ><a href="{$r[url]}" target="_blank" title="{$r[title]}"><img src="{thumb($r[thumb],1200,320)}" style="width:1200px; height:320px;" alt="{$r[title]}" /></a></div> {/loop} {/pc} <ul> {pc:content action="lists" catid="" thumb="1" order="listorder DESC" num="5"} {loop $data $r} <li><a href="{$r[url]}" target="_blank" title="{$r[title]}">{str_cut($r[title],20)}</a></li> {/loop} {/pc} </ul> <div></div> </div> </div> <span id="pre" class="arrow"> <</span> <span id="next" class="arrow">> </span> </div>
由于这个焦点幻灯比较特殊,图片和文字需要两次调用,另外,后台添加内容时要勾选首页焦点图推荐,就可以添加到首页

2.当然,这里面的css样式根据自己的需求做更改,在这里就不贴出css代码了,实现轮播需要加入以下js代码
window.onload=function(){//获取元素 var flowDiagram = document.getElementById('flowDiagram');//容器 var photo = document.getElementById("photo"); var button = document.getElementById("button").getElementsByTagName('span'); var pre = document.getElementById("pre"); var next = document.getElementById("next"); var index = 1; var m; function move(){ m = setInterval(next.onclick,3000); } function stop(){ if(m)clearInterval(m); } function buttonlight(){ for (var i = 0; i < button.length; i++) { if(button[i].className == "on"){ button[i].className = ""; break; } } button[index-1].className = "on"; } pre.onclick=function() { if (index == 1) index = 5; else index = index - 1; buttonlight(); photo.style.left = parseInt(photo.style.left) + 1200 + "px"; if (parseInt(photo.style.left) > -1200){ photo.style.left = -6000 + "px"; } } next.onclick = function(){//当right键被触发时响应 if (index == 5) index = 1; else index = index + 1; buttonlight(); photo.style.left = parseInt(photo.style.left) - 1200 + "px"; if (parseInt(photo.style.left) < -6000){ photo.style.left = -1200 + "px"; } } for (var i = 0; i < button.length; i++){ button[i].onclick = function() { if(this.className=="on") return; var currentindex = parseInt(this.getAttribute("index"));//getAttribute能获取自定义的属性值,也可以获取自带的属性值 var distance = currentindex - index; photo.style.left = parseInt(photo.style.left) - 1200 * distance + "px"; index = currentindex; buttonlight(); } } flowDiagram.onmouseover = stop; flowDiagram.onmouseout = move; move(); }
最终效果
