Sliding switch buttons can be seen on all major websites. Below, the editor will share with you an article about a sliding button switch effect based on jquery. Interested friends can refer to the implementation code.

Code: 

<!DOCTYPE html> 
<html> 
<head> 
<meta charset="UTF-8"> 
<title>jquery做的滑动按钮开关</title> 
<link rel="stylesheet" type="text/css" href="bootstrap/bootstrap.min.css"/> 
</head> 
<style> 
.switch{ 
width: 100px; 
margin: 100px 0px 0 100px; 
} 
.btn_fath{ 
margin-top: 10px; 
position: relative; 
border-radius: 20px; 
} 
.btn1{ 
float: left; 
} 
.btn2{ 
float: right; 
} 
.btnSwitch{ 
height: 40px; 
width: 50px; 
border:none; 
color: #fff; 
line-height: 40px; 
font-size: 16px; 
text-align: center; 
z-index: 1; 
} 
.move{ 
z-index: 100; 
width: 40px; 
border-radius: 20px; 
height: 40px; 
position: absolute; 
cursor: pointer; 
border: 1px solid #828282; 
background-color: #f1eff0; 
box-shadow: 1px 2px 2px 1px #fff inset,0 0 5px 1px #999; 
} 
.on .move{ 
left: 60px; 
} 
.on.btn_fath{ 
background-color: #5281cd; 
} 
.off.btn_fath{ 
background-color: #828282; 
} 
</style> 
<body> 
<div> 
<div class="btn_fath clearfix on" onclick="toogle(this)"> 
<div data-state="on"></div> 
<div class="btnSwitch btn1">ON</div> 
<div class="btnSwitch btn2 ">OFF</div> 
</div> 
<div class="btn_fath clearfix off" onclick="toogle(this)"> 
<div data-state="off"></div> 
<div class="btnSwitch btn1">ON</div> 
<div class="btnSwitch btn2 ">OFF</div> 
</div> 
</div> 
<script type="text/javascript" src="jquery/jquery.min.js"></script> 
<script type="text/javascript" src="bootstrap/bootstrap.min.js"></script> 
<script type="text/javascript"> 
function toogle(th){ 
var ele = $(th).children(".move"); 
if(ele.attr("data-state") == "on"){ 
ele.animate({left: "0"}, 300, function(){ 
ele.attr("data-state", "off"); 
alert("关！"); 
}); 
$(th).removeClass("on").addClass("off"); 
}else if(ele.attr("data-state") == "off"){ 
ele.animate({left: &#39;60px&#39;}, 300, function(){ 
$(this).attr("data-state", "on"); 
alert("开！"); 
}); 
$(th).removeClass("off").addClass("on"); 
} 
} 
</script> 
</body> 
</html>

Things to note:

1. The speed used for sliding here is 300ms, which seems to be a constant speed, not linear speed; try to find out if there is a linear movement like ease in CSS3 of.

2. The callback function in the animate method is the function called after the exercise ends.

The above is the jQuery introduced by the editor = to implement the function of a sliding button switch. I hope it will be helpful to everyone
