在做web页面时，无论PC端还是移动端，我们会遇到滑块这样的效果，可能我们往往会想着去网上找插件，其实这个效果非常的简单，插件代码的的代码往往过于臃肿，不如自己动手，自给自足。首先看一下效果图：
1 .god-bottom .swifter-track{ 2 width: 50%; 3 height: 93%; 4 border-radius: 5px; 5 position: absolute; 6 right:0; 7 top:0; 8 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track1.png") no-repeat 0 55%; 9 background-size: 100% 70%; 10 -webkit-animation:track 0.5s infinite; 11 animation:track 0.5s infinite; 12 } 13 @keyframes track { 14 0%{ 15 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track1.png") no-repeat 0 55%; 16 background-size: 100% 70%; 17 } 18 35%{ 19 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track2.png") no-repeat 0 55%; 20 background-size: 100% 70%; 21 } 22 70%{ 23 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track3.png") no-repeat 0 55%; 24 background-size: 100% 70%; 25 } 26 100%{ 27 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track4.png") no-repeat 0 55%; 28 background-size: 100% 70%; 29 } 30 } 31 @-webkit-keyframes track { 32 0%{ 33 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track1.png") no-repeat 0 55%; 34 background-size: 100% 70%; 35 } 36 35%{ 37 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track2.png") no-repeat 0 55%; 38 background-size: 100% 70%; 39 } 40 70%{ 41 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track3.png") no-repeat 0 55%; 42 background-size: 100% 70%; 43 } 44 100%{ 45 background: url("http://images.cnblogs.com/cnblogs_com/luanhewei/880330/o_track4.png") no-repeat 0 55%; 46 background-size: 100% 70%; 47 } 48 }
1 function sliderFun(outDiv,inDiv,funName) { 2 var startX,endX,distance=0; 3 var dis=outDiv.clientWidth-inDiv.clientWidth; 4 inDiv.addEventListener(‘touchstart‘,function (e) { 5 startX=e.touches[0].clientX; 6 },false) 7 inDiv.addEventListener(‘touchmove‘,function (e) { 8 endX=e.touches[0].clientX; 9 distance=endX-startX; 10 if(distance<=dis&&distance>=0){ 11 inDiv.style.left=distance+‘px‘; 12 } 13 },false) 14 inDiv.addEventListener(‘touchend‘,function (e) { 15 if(distance<=dis&&distance>=0){ 16 inDiv.style.left=‘0px‘; 17 }else if(distance>=dis){ 18 funName(); 19 } 20 },false) 21 }
为了方便大多去测试呢，最后我把所有的代码一并贴上，希望可以帮助到大家：
