js实现密码框小眼睛的显示与隐藏
眼睛的实现需要借助fontawesome里面的小图标： 引入font-awesome文件：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<link href="https://cdn.bootcss.com/font-awesome/4.7.0/css/font-awesome.css" rel="stylesheet">
</head>
<body>
<input type="password" id="pwd" placeholder="请输入密码"/>
<i class="fa fa-eye" onclick="showhide()" id="eye"></i>
<script type="text/javascript">
var eye = document.getElementById("eye");
var pwd = document.getElementById("pwd");
function showhide(){
if (pwd.type == "password") {
pwd.type = "text";
eye.className=fa fa-eye-slash
}else {
pwd.type = "password";
eye.className=fa fa-eye
}
}
</script>
</body>
</html>
