    We can do validation of a form which is created in html by using javascript.

    In below example if we do not put any thing in fname field, then validateName function will alert a message that Name field is empty.

    eg:-

    1.    function validateName() {
    2.         var n = document.forms["firstform"]["fname"].value;
    3.         if (n == null || n == "") {
    4.             alert("Name field is empty");
    5.             return false;
    6.         }
    7.     }

    Html code

    1. <form name="firstform" action="test.amp";form.asp" onsubmit="return validateName()" method="post">
    2. Name: <input type="text" name="fname">
    3. <input type="submit" value="Submit">
    4. </form>
    Javascript
