本文使用js+jQuery实现轮播图,需要引用jquery包,另种实现分别是animate实现自适应的轮播,以及transform平滑轮播(在注释代码中)。
代码中的图片大家自己更换就可以了,样式和逻辑均写在js里。
html标签代码:
<div class="slider"> //轮播箭头 <p class="lastpic"><img src="../images/prev.png"> <p class="nextpic"><img src="../images/next.png"> //轮播图片 <ul id="slides" class="slides clearfix"> <li><img class="responsive" src="../images/wrap-page.jpg" alt="暂无图片"></li> <li><img class="responsive" src="../images/wrap-page.jpg" alt="暂无图片"></li> <li><img class="responsive" src="../images/wrap-page.jpg" alt="暂无图片"></li> <li><img class="responsive" src="../images/wrap-page.jpg" alt="暂无图片"></li> </ul> </div>
js代码:
<script type="text/javascript"> $(document).ready(function() { var len = $(".slider li").length-1; //给slider设置样式 $(".slider").css({ "width":"100%", "height": "inherit", "overflow": "hidden", "display":"inline-block" }); //给ul设置宽度 $(".slides").css({ "position": "relative", "width":((len+1)*100).toString()+"%", "margin":"0", "padding":"0"}); //给li设置百分比宽度 $(".slides li").css({ "width":(100/(len+1)).toString()+"%", "float":"left" }); //给图片设置宽度 $(".responsive").css({ "width":"100%", "height":"inherit" }); //控制点样式 $(".slider p").css({ "position": "absolute", "z-index":"999", "cursor": "pointer" }); $(".slider .lastpic").css({ "left":"0", "margin-top":"7%" }); $(".slider .nextpic").css({ "right":"0", "margin-top":"7%" }); //animate移动 var i = 0; $(".nextpic").click(function(){ moveNext(i); }); $(".lastpic").click(function(){ moveLast(i); }); //自动轮播 var timer = setInterval(function(){ moveNext(i); },5000); moveNext = function(n){ if(n==len){ i=-1; $(".slider .slides").animate({right: ""},800); }else{ $(".slider .slides").animate({right:((n+1)*100).toString()+"%"}, 800); } i++; } moveLast = function(n){ if(n==0){ i=len+1; $(".slider .slides").animate({right:(len*100).toString()+"%"}, 800); }else{ $(".slider .slides").animate({right:((n-1)*100).toString()+"%"}, 800); } i--; } //手机触摸效果 var startX,endX,moveX; function touchStart(event){ var touch = event.touches[0]; startX = touch.pageX; } function touchMove(event){ var touch = event.touches[0]; endX = touch.pageX; } function touchEnd(event){ moveX = startX - endX; if(moveX>50){ moveNext(i); }else if(moveX<-50){ moveLast(i); } } document.getElementById("slides").addEventListener("touchstart",touchStart,false); document.getElementById("slides").addEventListener("touchmove",touchMove,false); document.getElementById("slides").addEventListener("touchend",touchEnd,false); //transition移动固定宽度,无法自适应 // $(".nextpic").click(function(){ // if(i==len){ // i=-1; // $(".slider .slides").css({ // 'transition-timing-function':'linear', // 'transition-duration':'800ms', // 'transform':'translateX(0px)' // }) // }else{ // $(".slider .slides").css({ // 'transition-timing-function':'linear', // 'transition-duration':'800ms', // 'transform':'translateX(-'+(i+1)*width+'px)' // }) // } // i++; // }); // $(".lastpic").click(function(){ // if(i==0){ // i=len+1; // $(".slider .slides").css({ // 'transition-timing-function':'linear', // 'transition-duration':'800ms', // 'transform':'translateX(-'+len*width+'px)' // }) // }else{ // $(".slider .slides").css({ // 'transition-timing-function':'linear', // 'transition-duration':'800ms', // 'transform':'translateX(-'+(i-1)*width+'px)' // }) // } // i--; // }) }); </script>
