Capitalize small alphabet

[vikas251074]

If a user types either small or capital alphabets in <input type="text"/> tag, then it should become all capital. Can this be done using javascript?

Thanks and regards,

You can use String.toUpperCase(); to convert string to uppercase.

I have written as follows.

Created a function capital() in javascript tag like this

<script type="text/javascript">
function capital(temp){
  return String.toUpperCase(temp); 
}
</script>

And called this function like this

<td align="left"><input type="text" style="width:250px " name="vlan_name" onchange="return capital(this);"/></td>

Also I used onblur event in place of onchange event.

It does not work.

You can use this function

<script type="text/javascript">
function capital(temp){
    var str=temp.value
  document.getElementById('vlan_name').value = str.toUpperCase(); 
}
</script>

and call function as

[HTML]<input type="text" style="width:250px " name="vlan_name" id="vlan_name" onkeyup="capital(this);"/>[/HTML]

Yes, you are right madam,

My problem is solved. But this function (capital()) can not be used multiple times for other <input tag>. How can I do this?

Suppose there are three fields,
vlan_name, vlan_location, vlan_type.
Then I want to use capital() in all three cases.

This line
document.getElementById('vlan_name').value = str.toUpperCase();
makes difficult for using multiple times.

Thanks and regards

Instead of

document.getElementById('vlan_name').value = str.toUpperCase(); 

use

document.getElementById(temp.id).value = str.toUpperCase();
