图片轮播效果实现代码(轮播图样式代码)
怎么用html5+css3 实现图片轮播
1、首先我们创建一个简单的项目,如图所示包括html,css和img三个。
2、这里是html文件,引入css和html代码文件,如图所示。
3、这里是css文件代码,上面是div和图片显示的效果代码,后面是动画效果。
4、这里是事件,这里定义了四个时间段的状态,兼容了ie的。
5、如图所示这里是效果图,会根据时间轮播显示下一张图片 了。
HTML图片轮播代码怎么写?
一、数字键控制代码:
div style="position:relative; top:-50px; left:240px;"
a href="javascript:show(1)"span id="I1" style="width:18px; text-align:left; background:gray"1/span/a
a href="javascript:show(2)"span id="I2" style="width:18px;text-align:left;background-color:gray"2/span/a
a href="javascript:show(3)"span id="I3" style="width:18px;text-align:left;background-color:gray"3/span/a
a href="javascript:show(4)"span id="I4" style="width:18px;text-align:left;background-color:gray"4/span/a
a href="javascript:show(5)"span id="I5" style="width:18px;text-align:left;background-color:gray"5/span/a
a href="javascript:show(6)"span id="I6" style="width:18px;text-align:left;background-color:gray"6/span/a/div
script language="javaScript"
var nowIndex=1;
var maxIndex=6;
function show(index)
{
if(Number(index)){
clearTimeout(theTimer);
nowIndex=index;
}
for(var i=1;i(maxIndex+1);i++){
if(i==nowIndex)
{document.getElementById('pic'+nowIndex).style.display='';
document.getElementById('I'+nowIndex).style.backgroundColor='red';}
else
{document.getElementById('pic'+i).style.display='none';
document.getElementById('I'+i).style.backgroundColor='gray';}
}{
if(nowIndex==maxIndex)
nowIndex=1;
else
nowIndex++;
}
theTimer=setTimeout('show()',3000);
}
/script
/div
二、图片自动播放:
div id="butong_net_left" style="overflow:hidden;width:1000px;"
table cellpadding="0" cellspacing="0" border="0"
trtd id="butong_net_left1" valign="top" align="center"
table cellpadding="2" cellspacing="0" border="0"
tr align="center"
js如何制作图片轮播
工具/材料
Sublime Text
01
首先在Sublime Text下面准备一个html和5张图片,图片宽高为600px和400px,如下图所示
02
然后在HTML页面中布局轮播图的结构,如下图所示,主要包括图片区域,圆形按钮,左右箭头
03
接下来需要给轮播图页面布局声明一些样式,请按照下图所示的样式代码进行声明
04
最后就是实现轮播图的JS脚本功能,如下图所示,主要包括前进,后退,自动播放的功能
05
最后运行页面,你就会看到下图所示的轮播图效果,点击圆圈或者左右箭头可以切换轮播图
