changing textbox border colour using javascript
Use CSS styles with CSS Classes instead
CSS
.error { border:2px solid red;}Now in Javascript
document.getElementById("fName").className = document.getElementById("fName").className + " error"; // this adds the error classdocument.getElementById("fName").className = document.getElementById("fName").className.replace(" error", ""); // this removes the error classThe 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.
You may try
document.getElementById('name').style.borderColor='#e52213';document.getElementById('name').style.border='solid';
