What does "is not working" mean? Have you debugged it?

Sweety Khan 3-Apr-12 15:47pm

php header not working, everything else is fine. when correct emailid and password enter by user, www.hotmail.com should open but it doesnt open.

Where is the "PHP header" in your code?
Anyway, the question does not seem to make sense as PHP works on server side, and JavaScript -- on client side.

Please see my comment to the question. The line

PHP

header('Location: http://www.hotmail.com');

makes no sense in principle, because this is PHP, something which should generate header on the server side, before HTML or JavaScript, or any other content appears in the HTTP response on the client side. From PHP standpoint, JavaScript is merely a piece of data to be written in response to HTTP request, some content. Even if you put this line in <?php … ?>, it still wouldn't make any sense. This is not something which could be somehow "fixed"; it looks like you don't understand generally how server side and client side work.

Also, even the jQuery part of the code is bad: using document.getElementById defeats the purpose of jQuery, where you can use selectors instead; please see:
http://api.jquery.com/category/selectors/[^],
http://api.jquery.com/id-selector/[^].

It looks like you don't understand what are you writing. Do your try to write something based on some available code samples? Normally, it does not work like that; you need to understand each like you are writing.

yeh u right using php header in javascript is senseless. i post the question beacuse i wanted to know something like php header that can be used in js which is now told by Graham Breach. yeh i take a sample code and edit it for the work i want to do but i know each and every part. whats wrong in using document.getElementById? i saw the links, there is clearly written "jQuery uses the JavaScript function document.getElementById(), which is extremely efficient" so i dont understand why u r saying using it is bad

document.getElementById is not wrong per se, it defeats the purpose of jQuery where it is already implemented in descriptors, for your convenience. It's like using C++ without classes and virtual methods.

now i understand after searching tht u mean i should code this
var n = $('#email').val();
var p = $('#pw').val();
right?

Sergey Alexandrovich Kryukov 12-Apr-12 12:41pm

Well, this is correct if you want to get element's value:
http://api.jquery.com/val/
I don't know how is it related to your original question though...

No, the PHP header function does not work in Javascript (and it doesn't make a lot of sense trying to use it from Javascript).

I think what you really want to do is a redirect from Javascript. You can use something like this:

JavaScript

location = 'http://www.hotmail.com/';
