javascript

var index=0;//周期:2秒 auto_play后不能加括號var circulate=setInterval(auto_play,2000);//函數后面不能加括號//自動播放function auto_play(){ //alert(index); if(index>=3) {index=0;} else {index=index+1;} changePic(index); /*$(".imgview img").css("display","none");*/ //$(".imgview img").attr("src",imgs[index]); //alert(index);}//切換圖片 function changePic(index){  //alert(index);  $(".imgview a").css("display","none");  $(".box a").css("display","none");  $(".circles a").css("background","#000");  //var src=$(".imgview a:eq("+index+")").attr("target");  //alert(src);  $(".imgview a:eq("+index+")").css("display","inline");  $(".box a:eq("+index+")").css("display","block");  $(".circles a:eq("+index+")").css("background","red");  //alert(src); }//鼠標進入播放區域 暫停播放 $(".imgview").mouseenter(function(){  //alert("hi!");  clearInterval(circulate); }) //鼠標移出播放區域 開始播放 $(".imgview").mouseleave(function(){  //alert("hi!");  circulate=setInterval(auto_play,2000); }) //鼠標移入序號圓點 切換到序號所對應圖 $(".circle").mouseenter(function(){  //如何確定當前circle的序號?  var num=$(this).index();  //alert(num);  clearInterval(circulate);  changePic(num);  circulate=setInterval(auto_play,2000); });//點擊左邊箭頭 切換到上一張 $(".carousel-btn-prev").click(function(){  clearInterval(circulate);  //alert(index);  //1.現在處在第幾張 :index;  if(index==0)index=3;  else index=index-1;  changePic(index);  circulate=setInterval(auto_play,2000); }); //點擊右邊箭頭 切換到下一張 $(".carousel-btn-next").click(function(){  clearInterval(circulate);  //alert(index);  //1.現在處在第幾張 :index;  if(index==3)index=0;  else index=index+1;  changePic(index);  circulate=setInterval(auto_play,2000); });
