Answer / rajikiran

function validate()
{
if(document.getElementById("NameId").value == null)
alert("Please enter the name");
document.getElementById("NameId").focus();
return false;
}

or

function validate()
{
with(document.formname)
{
txtboxid.value == ""
alert("Please enter value");
txtboxid.focus();
return false;
}
}

or we can use

document.form.txtboxid.value

instead of

document.getElementById("NameId").value
