The HTML input readonly attribute is used to declare an input element unmodifiable, though it still may be copied.
Let us see an example of Input readOnly property −
Example
<!DOCTYPE html>
<html>
<head>
<title>Input Email readOnly</title>
<style>
form {
width:70%;
margin: 0 auto;
text-align: center;
}
* {
padding: 2px;
margin:5px;
}
input[type="button"] {
border-radius: 10px;
}
</style>
</head>
<body>
<form>
<fieldset>
<legend>Email-readOnly</legend>
<label for="EmailSelect">Contact Us :
<input type="email" id="EmailSelect" onclick="showErrorMsg()" value="[email protected]" readOnly>
</label>
<input type="button" onclick="showMessage()" value="Copy Email Id">
<div id="divDisplay"></div>
</fieldset>
</form>
<script>
var divDisplay = document.getElementById("divDisplay");
var inputEmail = document.getElementById("EmailSelect");
divDisplay.textContent = 'Above email is read-only';
function showMessage() {
inputEmail.select();
document.execCommand('copy');
divDisplay.textContent = 'Email Copied: '+inputEmail.value;
}
function showErrorMsg(){
divDisplay.textContent +=', This cannot be edited.'
}
</script>
</body>
</html>This will produce the following output −
1) Before clicking ‘Copy Email Id’ button −
2) Clicking ‘Contact Us’ email field −
3) Clicking ‘Copy Email Id’ −
