This article mainly introduces the js implementation of clicking the button to edit. It has a certain reference value. Now I share it with everyone. Friends in need can refer to it

<script type="text/javascript">
//修改密码
//抓取到的数据
   function edit() {
       document.getElementById("ps").style.display = "none";
       document.getElementById("pw").style.display = "";
       document.getElementById("of").style.display = "";
       var butt = document.getElementById("btt");
       butt.value = "修 改";
       butt.onclick = function () {
           save();//第二次单击的时候执行这个函数
       };
   }
//取消健
   function off() {
   	var pass = document.getElementById(&#39;ps&#39;);
       var pws = document.getElementById("pw");
       var butt = document.getElementById("btt");
       document.getElementById("of").style.display = "none",
       butt.value = "编 辑";
       pws.style.display = "none";
       pass.innerHTML = pws.value;
       pass.style.display = "";
       butt.onclick = function () {
           edit();//还原第一次单击的时候执行的函数
       };
   }
//编辑之后的状态
   function save() {
       var pass = document.getElementById(&#39;ps&#39;);
       var pws = document.getElementById("pw");
       var butt = document.getElementById("btt");
       butt.setAttribute("type","submit");
       butt.value = "编 辑";
       pws.style.display = "none";
       pass.innerHTML = pws.value;
       pass.style.display = "";
       butt.onclick = function () {
           edit();//还原第一次单击的时候执行的函数
       };
   }
</script>

<form action="oneself.php" method="post">
