phpcms首頁實現輪播圖

1.在你想要加輪播圖的位置加入以下

<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"> &lt;</span>
<span id="next" class="arrow">&gt; </span>
    </div>

由於這個焦點幻燈比較特殊，圖片和文字需要兩次調用，另外，后台添加內容時要勾選首頁焦點圖推薦，就可以添加到首頁

 

2.當然，這里面的css樣式根據自己的需求做更改，在這里就不貼出css代碼了，實現輪播需要加入以下js代碼

window.onload=function(){//獲取元素
    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(){//當right鍵被觸發時響應 
        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能獲取自定義的屬性值，也可以獲取自帶的屬性值
            var distance = currentindex - index;
            photo.style.left = parseInt(photo.style.left) - 1200 * distance + "px";
            index = currentindex;
            buttonlight();
        }
    }
    flowDiagram.onmouseover = stop;
    flowDiagram.onmouseout = move;
    move();
}

最終效果
