Can not find the problem. mainly when I giving the code inside "else if". It is not working.
<html> <head> <script> function val(){ var n=document.getElementById("n").value; if(n==""){ document.getElementById("error").innerHTML="enter name"; return false; } if else(n!=""){ document.getElementById("error").innerHTML=""; } } </script> </head> <body> <form name="myf" onSubmit="return val()"> Name:<input type="text" name="Name" id="n"/><br/><p id="error"></p> Address:<input type="text" name="Add" id="a"/><br/><p id="error_1"></p><br/> <input type="submit" value="submit"/> </form> </body> </html>

I tried the code and it seems to be working fine... Whenever I leave Name empty, "enter name" shows up. When I do put a name, it disappears.
You can try to access the developer console (in Chrome, push F12) and see if you have errors in the Javascript console.

if else(n!="")
Should be just an else, since you want it to execute if n!=""
As a side note, that is not the correct syntax for an else-if statement: else should precede the if
Also, I think you meant to type:
n=document.getElementById("n").value;
after:
var invalid=0;

sorry. I posted a wrong code. but now I've changed it

Ok :)
you still need, at least, to reverse the if and the else in:
if else(n! ="")
But you actually only need an else, since you already tested for n == "" in the previous if
