What I will bring to you this time is how to use JS to disable and enable buttons. Buttons are used very frequently when we are doing projects. This article will give you a good analysis.

No more nonsense, I will just post the code for you. The specific code is as follows:

<script type="text/javascript">
function btn1()
{
 document.getElementById("btn1").disabled=true;
 document.getElementById("btn1").innerHTML="禁用按钮1";
 document.getElementById("btn2").disabled=false;
 document.getElementById("btn2").innerHTML="启用按钮2";
 }
 //按钮2
function btn2()
{
 document.getElementById("btn1").disabled=false;
 document.getElementById("btn1").innerHTML="启用按钮1";
 document.getElementById("btn2").disabled=true;
 document.getElementById("btn2").innerHTML="禁用按钮2";
 }
</script>
</head>
<body>
<div style="position:absolute;left:400px;top:200px">
<button id="btn1" onclick="btn1();" style="width:100px;height:100px; ">按钮1</button>
<button id="btn2" onclick="btn2();" style="width:100px;height:100px; margin-left:100px ">按钮2</button>
</div>
</body>
</html>
