for example form validation:
<html>
<head>
<script type="javascript">
function formvalidation(form)
{
if (nonempty(form.req1))
{
if (nonempty(form.req2))
{
return true;}}
return false;}
function nonempty(elem)
{
char str=elem.value;
if(str.length==0)
{
alert("u must fill in all records");
return false;
}
else
return true;
}
</script>
</head>
<body>
<form name="example" onsubmit="return formvalidation(this)">

entry 1<input type="text" name="req1"><br>
entry 2<input type="text" name="req2"><br>
<value="submit">
</form>
</body>
