如何在网页设计中旋转图片
html中的代码:
& ltdiv id = & quot方框& quot& gt
& ltdiv id = & quot我在猴墩& quotclass = & # 39隐藏& # 39;& gt
& lta id = & quotbtnLeft & quothref = & # 39JavaScript:void(0);'& gt& lt/a & gt;
& lta id = & quotbtnRight & quothref = & # 39JavaScript:void(0);'& gt& lt/a & gt;
& ltul & gt
<li><img width="400" height="260" src="./images/scholl/1.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/1 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/2.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/2 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/3.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/3 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/1.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/1 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/2.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/2 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/3.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/3 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/1.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/1 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/2.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/2 . jpg & quot;/& gt;& lt/李& gt
<li><img width="400" height="260" src="./images/scholl/3.jpg"/></li>& lt李& gt& ltimg width = & quot400 quot;height = & quot260 & quotsrc = & quot。/images/scholl/3 . jpg & quot;/& gt;& lt/李& gt
& lt/ul & gt;
& lt/div & gt;
js中的代码:
ar t = null
函数woZaiHouDun(){
var oUl = document . getelementbyid(& # 39;我在后墩& # 39;).getElementsByTagName(& # 39;ul & # 39)[0];
var aLi = oul . getelementsbytagname(& # 39;李& # 39;);
oul . innerhtml
= oul . innerhtml;
oUl.style.width = aLi[0]。offsetWidth * Ali . length
& # 39;px & # 39;
var oBtnLeft = document . getelementbyid(& # 39;btnLeft & # 39);
var oBtnRight = document . getelementbyid(& # 39;btnRight & # 39);
var iTarget = 0;
var is peed =-3;
oBtnLeft.onclick = function(){
is peed = 3;
}
oBtnRight.onclick = function(){
ispeed =-3;
}
t=setInterval(function(){
iTarget = oul . offset left-is peed;
if(iTarget & lt;- oUl.offsetWidth/2){
oul . style . left = 0
& # 39;px & # 39;
iTarget = oul . offset left-is peed;
}
if(iTarget & gt;0){
oul . style . left =-oUl.offsetWidth/2
& # 39;px & # 39;
iTarget = oul . offset left-is peed;
}
oul . style . left = iTarget
& # 39;px & # 39;
},30)
}
这可以实现旋转木马。
dw怎么做图片轮播?
dw做图片轮播步骤如下:
1.
首先打开你的dw,按快捷键ctrl+n创建一个新的网页。
2.
点菜单栏上的表格,插入一个表格。
3.
在属性栏设置表格的宽和高,这个表格用于添加轮播广告,所以宽和高都要符合我们的广告图片的宽和高。
4.
然后点击插入添加一个可编辑区,这个区域在此例子中没用,只是为了能够保存模板,所以随意加一个即可。
