changing textbox border colour using javascript

The Solution to changing textbox border colour using javascript is

Use CSS styles with CSS Classes instead


.error {
  border:2px solid red;

Now in Javascript

document.getElementById("fName").className = document.getElementById("fName").className + " error";  // this adds the error class

document.getElementById("fName").className = document.getElementById("fName").className.replace(" error", ""); // this removes the error class

The main reason I mention this is suppose you want to change the color of the errored element's border. If you choose your way you will may need to modify many places in code. If you choose my way you can simply edit the style sheet.
