    Is there a way to disable an existing button (I've used the tag <INPUT TYPE="submit"> ) when text input field has no value in it.And enable it when a value is entered.Or can it be done using <INPUT TYPE="button">.

    I'm not sure about disabling the button, but one thing you can do is to make a for loop which checks to see if it has a value, and if it doesn't, display a message and not do anything until all fields are filled.
    Here's an example:

    var filledField;
    for (var i = 0; i < document.yourForm.elements.length; i++) {
    if (document.yourForm.yourTextbox != "") {
    if (filledField < numberOfFields) {
    alert("Please fill out all fields before continuing");
    //What you want to do when the field is //filled
    Hope this helps.
