Text readOnly Property
Text Object
The readOnly property sets or returns whether a text field is read-only, or not.
A read-only field cannot be modified. However, a user can tab to it, highlight it, and copy the text from it.
Tip: To prevent the user from interacting with the field, use the disabled property instead.
Syntax
Set the readOnly property:
textObject.readOnly=true|false
Return the readOnly property:
textObject.readOnly
Browser Support
The readOnly property is supported in all major browsers.
Example
Example
Set a text field to be read-only:
<html>
<head>
<script type="text/javascript">
function setResult()
{
document.getElementById("email").readOnly=true;
}
</script>
</head>
<body>
<form>
Email: <input type="text" id="email" />
</form>
<button type="button" onclick="setResult()">Set read-only</button>
</body>
</html>
