phpcms如何实现轮播
phpcms实现轮播的方法:首先在想要加轮播图的位置加入“...”;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
< >{pc:content action="position" posid="1" thumb="1" order="listorder DESC" num="5"} {loop $data $r} {/loop} {/pc}{pc:content action="lists" catid="" thumb="1" order="listorder DESC" num="5"} {loop $data $r}
- {str_cut($r[title],20)}
{/loop} {/pc}
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
