方式一:
<script> window.onload=load; function load(){ var arrImgs=[‘1.jpg‘,‘2.jpg‘,‘3.jpg‘,‘4.jpg‘]; var img = document.getElementById("img"); var index =0; img.onclick=changeImg;//点击图片实现轮播 setInterval(changeImg,500);//自动轮播图片方式1 //轮播图片 function changeImg(){ if(index==arrImgs.length){ index=0; } img.src = "images/"+arrImgs[index];//图片在images目录下 index++; } } </script> </body> <img src="images/photo_01.jpg" id="img" width="300" height="300" border="1px solid #f00"> </html>
方式二:
<script> window.onload=load; function load(){ var arrImgs=[‘1.jpg‘,‘2.jpg‘,‘3.jpg‘,‘4.jpg‘]; var img = document.getElementById("img"); var index =0; showBySetOut();//自动轮播图片方式2 //轮播图片 function changeImg(){ if(index==arrImgs.length){ index=0; } img.src = "images/"+arrImgs[index];//图片在images目录下 index++; } //通过setTimeout是实现自动定时 function showBySetOut(){ changeImg(); setTimeout(showBySetOut,1000); } } </script> </body> <img src="images/photo_01.jpg" id="img" width="300" height="300" border="1px solid #f00"> </html>
