Yes,

You can set an attribute with the setAttribute method.

>...then give me exact function with parameters.....

The code in my previous e-mail was doing what you wanted.
You have to do some coding of your own, you know, to adapt it to your
specific needs.

So change the the input button to a link...
Same code and everything, just:

function
ckVal(oElm){

document.getElementById("aLink").disabled =3D (oElm.value =3D=3D "Some
text...")? true : false;
document.getElementById("aLink").onclick =3D function (){
return (this.disabled)? false : true; // This is
necessary to disable the built-in behavior of the link
}
}


<input type=3D"text" value=3D"Some text..." onChange=3D"checkVal(this)">

<a id=3D"aLink" href=3D"http://www.google.com">A link</a>


BTW, this will only work in IE 5.5.+...

function checkVal(oElm){
if(oElm.value =3D=3D "Some text..."){
document.getElementById("submitButton").disabled =3D true; } else{
document.getElementById("submitButton").disabled =3D true; } }

(or a neater version of the function:

function checkVal(oElm){
document.getElementById("submitButton").disabled =3D (oElm.value =3D=3D 
"Some
text...")? true : false; }

)

<input type=3D"text" value=3D"Some text..." onChange=3D"checkVal(this)">

<input id=3D"submitButton" name=3D"submitButton" type=3D"submit"
value=3D"Submit">
