JavaScript实现input密码框显示/隐藏的功能，供大家参考，具体内容如下
实现代码：
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
.password{
position: relative;
width: 280px;
height: 60px;
}
.password,.n-txtCss{
display: flex;
align-items: center;
}
.password .fa{
position: absolute;
right: 10px;
top:15px;
font-size: 20px;
cursor: pointer;
}
.fa-eye-slash{
margin-top: 6px;
margin-left: 7px;
width: 24px;
height: 20px;
background-image: url(./vivo_img/login/eye-password.png);
background-repeat: no-repeat;
background-size: 24px 17px;
}
.fa-eye{
margin-top: 6px;
width: 24px;
margin-left: 7px;
height: 20px;
background-image: url(./vivo_img/login/eye-password-active.png);
background-repeat: no-repeat;
background-size: 24px 17px;
}
</style>
<script type="text/javascript" src="js/jquery-1.12.4.min.js"></script>
</head>
<body>
<dd class="password">
<input type="password" name="" placeholder="设置密码：8-16位字母和数字" maxlength="16" style="outline: none;width: 240px;">
<i class="fa fa-eye-slash"></i>
</dd>
<script type="text/javascript">
$(".password").on("click", ".fa-eye-slash", function () {
$(this).removeClass("fa-eye-slash").addClass("fa-eye");
$(this).prev().attr("type", "text");
});
$(".password").on("click", ".fa-eye", function () {
$(this).removeClass("fa-eye").addClass("fa-eye-slash");
$(this).prev().attr("type", "password");
});
</script>
</body>
</html>
