phpcms如何实现轮播-PHPCMS

phpcms完成轮播的办法：起首正在想要加轮播图的地位退出“<div id="flowDiagram" >...</div>”；而后依据本人的需要对css款式进行更改；最初正在需求完成轮播之处退出js代码便可。

phpcms首页完成轮播图

1.正在你想要加轮播图的地位退出如下

<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>

因为这个焦点幻灯比拟非凡，图片以及文字需求两次挪用，另外，后盾增加内容时要勾选首页焦点图保举，就能够增加到首页

2.当然，这外面的css款式依据本人的需要做更改，正在这里就没有贴出css代码了，完成轮播需求退出如下js代码

window.onload=function(){//猎取元素
    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键被触发时呼应
        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能猎取自界说的属性值，也能够猎取自带的属性值
            var distance = currentindex - index;
            photo.style.left = parseInt(photo.style.left) - 1200 * distance + "px";
            index = currentindex;
            buttonlight();
        }
    }
    flowDiagram.onmouseover = stop;
    flowDiagram.onmouseout = move;
    move();
}

终极成果
