document.getElementById('telheaderid').yourattribute = "your_value";
For instance
document.getElementById('telheaderid').value = "your_value";
Using jQuery:
$('#telheaderid').attr('value', 'your_value');
EDIT:
Focus is the event that fires up when an element get focused or for instance when we click on the textarea it highlights thats the time.
Using jQuery:
$('#telheaderid').focus(function() {
$(this).val('');
// run any code when the textarea get focused
});
Using plain javascript:
document.getElementById('telheaderid').addEventListener('focus', function() {
this.value = "";
});

Try to add this code in javascript console and then try if it works then you must be running this code somewhere wrong

It works on the console but not if i add it to the header.php, what am i doing wrong? I can see the code there..

Add this script tag in footer.php just after the body tag ends instead of header.php and try again man! This time I think it would work. And don't forget to accept the answer!

A second method would be to wrap your code in
$(document).ready(function(){ /* your code here */ }); |
Use this:
document.getElementById('telheaderid').setAttribute('class','YourAttribute')

But i already can set the class, i need to add an attribute like "OnClick" for example so then i add another function, onClick and i can make it clear the value.

This works with any Attribute. You can replace the 'class' with e.g. 'onclick','name','style','onblur' etc.
The W3C standard way:
function functionAddAttribute(){
document.getElementById('telheaderid').setAttribute('attributeName', 'attributeValue');
};
window.onload = functionAddAttribute;
for IE:
function functionAddAttribute(){
document.getElementById('telheaderid').attributeName = 'attributeValue';
};
window.onload = functionAddAttribute;
Enjoy your code!

Computer's Guy
Thank you, can you try initializing it with a default value then clearing it with the javascript please?
Magicianred
Here is the link: jsfiddle.net/4b4U9/2 you can use setAttribute o removeAttribute
Magicianred
Why not? You see the alert box? The attribute size has blank, or not? Which browser use? Which version?
