HTML DOM Input Datetime readOnly Property
The HTML DOM Input Datetime readOnly property sets/returns whether Input Datetime can be modified or not.
Following is the syntax −
- Returning boolean value - true/false
inputDatetimeObject.readOnly
- Setting readOnly to booleanValue
inputDatetimeObject.readOnly = booleanValue
Boolean Values
Here, “booleanValue” can be the following −
| booleanValue | Details |
|---|---|
| true | It defines that the input datetime is readOnly. |
| false | It defines that the input datetime is not readOnly and can be modified. |
Let us see an example of Input Datetime readOnly property −
<!DOCTYPE html> <html> <head> <title>Input Datetime readOnly</title> </head> <body> <form> Final Exam Datetime: <input type="datetime" id="datetimeSelect" value="2023-08-24T10:30Z"> </form> <button onclick="finalizeDatetime()">Confirm Datetime</button> <div id="divDisplay"></div> <script> var divDisplay = document.getElementById("divDisplay"); var inputDatetime = document.getElementById("datetimeSelect"); divDisplay.textContent = 'Exam Datetime Finalized: '+inputDatetime.readOnly; function finalizeDatetime() { inputDatetime.readOnly = true; divDisplay.textContent = 'Exam Datetime: '+inputDatetime.value; } </script> </body> </html> Output
