Adding Jquery for the Contact Us Form

So as each jquery file, in template.php you can add the js file with:

(path_to_theme(). '/'); ?>
In our JS File,, we add a function to the submit function, which checks whether all fields are filled up, if not it alerts some messages

if (Drupal.jsEnabled) {
  $(document).ready(function() {
  $('form#contact-mail-page').submit(function () {
    //if one of this fields as nothing in print out that the form is not ready yet
    //  if ready the field is send
    if ($('#contact-mail-page #edit-name').val() == "") {
      alert(Drupal.t("The Field @name isn't filled out yet", ['@name'] = Drupal.t("name")]);
      return false;
    else if ($('#contact-mail-page #edit-subject').val() == "") {
      alert(Drupal.t("The Field @name isn't filled out yet"), ['@name'] = Drupal.t("subject")]);
      return false;
    else if ($('#contact-mail-page #edit-mail').val() == "") {
      alert(Drupal.t("The Field @name isn't filled out yet"), ['@name'] = Drupal.t("mail")]);
      return false;
    else if ($('#contact-mail-page #edit-message').val() == "") {
      alert(Drupal.t("The Field @name isn't filled out yet"), ['@name'] = Drupal.t("message")]);
      return false;
    else {
      return true;

Managing JavaScript in Drupal 7

Drupal 7 has introduced several new techniques that allow you far greater flexibility and control in the scripts you can have on your Drupal site's pages.

Weighted JavaScript

drupal_add_js() now allows you to add a weight value to each script you’re adding so you can completely control the order in which the script tags appear:
- JS_LIBRARY: Any libraries, settings, or jQuery plugins.
- JS_DEFAULT: Any module-layer JavaScript.
- JS_THEME: Any theme-layer JavaScript
drupal_add_js('jQuery(document).ready(function () { alert("Hello!"); });', array('type' => 'inline', 'scope' => 'footer', 'weight' => 5));

Adding JavaScript in the module's .info file

You can now add Javascript in the module's .info file if it should be added on every page. This allows Javascript to be aggregated in an optimal way, and is the preferred method of adding Javascript that most visitors will need on a typical site visit:
scripts[] = somescript.js

External JavaScript

drupal_add_js() now allows you to add external scripts.
drupal_add_js('', 'external');

Overriding JavaScript

hook_js_alter() allows you to modify the path referenced by one of the scripts added by core or another module. An obvious example is if you want to use a newer version of jQuery than what comes with core:
function hook_js_alter(&$javascript) {
  $javascript['misc/jquery.js']['data'] = drupal_get_path('module', 'jquery_update') . '/jquery.js'; // Swap out jQuery to use an updated version of the library

JavaScript Libraries

There is now a standard way of adding collections of JavaScript and CSS, such as jQuery plugins. If you have a set of JavaScript and/or CSS that could be considered a package, provide it as a library to other modules by implementing hook_library(), and include it it in your own pages either by using #attached['library'] or drupal_add_library(). This is the preferred way to deal with JavaScript and CSS which might be used by other modules.
Modules define libraries which can be added when needed. For example, system.module defines the Vertical Tabs library, which includes one js file and one css file:
function system_library() {
  // Vertical Tabs.
  $libraries['vertical-tabs'] = array(
    'title' => 'Vertical Tabs',
    'website' => '',
    'version' => '1.0',
    'js' => array(
      'misc/vertical-tabs.js' => array(),
    'css' => array(
      'misc/vertical-tabs.css' => array(),
  return $libraries;

The library gets added when it's needed, through a call to drupal_add_library:
function theme_vertical_tabs($variables) {
  $element = $variables['element'];
  // Add required JavaScript and Stylesheet.
  drupal_add_library('system', 'vertical-tabs');

  return '<div class="vertical-tabs-panes">' . $element['#children'] . '</div>';

Prefer drupal_add_library() and always use it for core JavaScript files

drupal_add_js() should not be used for JavaScript which is already included in a library (as all core JavaScript libraries are). Use drupal_add_library() instead.

Using jQuery

jQuery is now namespaced to avoid conflicts with other Javascript libraries such as Prototype. All your code that expects to use jQuery as $ should be wrapped in an outer context like so.
(function ($) {
  // All your code here

If you don't, you may see the error Uncaught TypeError: Property '$' of object [object DOMWindow] is not a function or similar.


Behavior handling has changed again in Drupal7, with modules now required to explicitly define their attach handler, and optionally specify a detach handler.
Instead of the settings being a global object, settings are now passed to your handlers directly, after the context.
These changes, besides namespaced jQuery, mean basic module code should go from
something like this in Drupal 6:
Drupal.behaviors.exampleModule = function (context) {
   $('.example', context).click(function () {
To something like this in Drupal 7:
(function ($) {

  Drupal.behaviors.exampleModule = {
    attach: function (context, settings) {
      $('.example', context).click(function () {


AJAX Forms in Drupal 7

* AJAX-enabled select element causes replacement of a set of checkboxes
* based on the selection.
//the AJAX-enabled element is a select, $form['howmany_select'], which causes replacement of the HTML ID 'checkboxes-div' (named in #ajax['wrapper']), which is a wrapper around a the fieldset $form['checkboxes_fieldset']:

function ajax_example_autocheckboxes($form, &$form_state) {

$default = !empty($form_state['values']['howmany']) ? $form_state['values']['howmany'] : 1;

$form['howmany_select'] = array(
'#title' => t('How many checkboxes do you want?'),
'#type' => 'select',
'#options' => array(1 => 1, 2 => 2, 3 => 3, 4 => 4),
'#default_value' => $default,
'#ajax' => array(
'callback' => 'ajax_example_autocheckboxes_callback',
'wrapper' => 'checkboxes-div',
'method' => 'replace',
'effect' => 'fade',


$form['checkboxes_fieldset'] = array(
'#title' => t("Generated Checkboxes"),
// The prefix/suffix provide the div that we're replacing, named by
    // #ajax['wrapper'] above.
'#prefix' => '<div id="checkboxes-div">',
'#suffix' => '</div>',
'#type' => 'fieldset',
'#description' => t('This is where we get automatically generated checkboxes'),

When the 'howmany_select' element is changed, a background request is issued to the server requesting that the form be rebuilt. After the form is rebuilt, using the changed 'howmany' field as input on how to rebuild it, the callback is called:

  $num_checkboxes = !empty($form_state['values']['howmany_select']) ? $form_state['values']['howmany_select'] : 1;
  for (
$i=1; $i<=$num_checkboxes; $i++) {
$form['checkboxes_fieldset']["checkbox$i"] = array(
'#type' => 'checkbox',
'#title' => "Checkbox $i",

$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Submit'),

* Callback element needs only select the portion of the form to be updated.
* Since #ajax['callback'] return can be HTML or a renderable array (or an
* array of commands), we can just return a piece of the form.
function ajax_example_autocheckboxes_callback($form, $form_state) {
The callback in this case (and in many cases) just selects the portion of the form which is to be replaced on the HTML page and returns it. That portion of the form is later rendered and returned to the page, where it replaces the #ajax['wrapper'] which was provided.
That's AJAX forms in a nutshell. A form element with the #ajax property submits a background request to the server when it is triggered by a click or change. The form gets rebuilt (on the server) by the form-builder function, and then the callback named in #ajax['callback'] is called, which selects the portion of the form to return for replacement on the original page.

Simple Form API Example

//Menu Hook
function formcreation_menu() {
$items = array();
$items['formcreation/new_form'] = array(
    'title' => t('New form'),
      'page callback' => 'drupal_get_form',
    'page arguments' => array('create_form'),
    'access arguments' => array('access content'),
    'description' => t('New form'),
    'type' => MENU_CALLBACK,
return $items;
// Menu Callback
function create_form($form_state) {

    '#type' => 'fieldset',
    '#title' => t('Personal Details'),

Solution For HTTP_REFERER not working in IE

Solution For HTTP_REFERER not working in IE:

The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted. 

If we use this in the firefox,it will work as fine as it is.But if we use this for IE,it will not fetch the url of the previous window,
So we will use the Javascript code here to get the url of the referrer window like this,

var strReferrer = window.opener.location.href;

use this code in your popup widow page js file,then pass that referrer url 'strReferrer' to the id 'referrer' to your tpl file as hidden value,

<input type="hidden" name="referpage" id="referrer" value="" />

then take this hidden value using $form value in ur module for your email the referrer window url,

$referrerpath = $form['aaa']['#post']['referrer'];

Here you can get that url,,,

Multiple Email Validation using Jquery

Simple Jquery Validation for Sending Multiple Email:

After creating a form with submit button,Call the jquery function in that submit button while Onclicking,
Use this submit button code, if your submit button with image,

$form['send'] = array(
         '#type' => 'image_button',
         '#src' => path_to_theme() . "/images/btn_0_0_send_off.gif",
         '#attributes' => array('onclick' => "validateEmailForm(); return false;", 'onMouseOver'=>"this.src=Drupal.settings.basePath + 'your image path/btn_0_0_send_ro.gif';",'onMouseOut'=>"this.src=Drupal.settings.basePath + 'your image path/btn_0_0_send_off.gif';" ),

Now we are validating that Multiple email field,assume that the field id is"edit-mailid",..

$(function () {

    validateEmailForm = function(){           

        var mailid  = $('#edit-mailid').val();
/* Your Mail address Validation */
        if(mailid  == ''){
            errorCount = 1;
            error+="<li>You must supply a value for the 'mailid' field of this form.</li>";
        else {
            var result = mailid  .split(",");
            for(var i = 0;i < result.length;i++)
                if(!validate_email(result[i])) {
                    errorCount = 1;
                    error+="<li>Please enter a valid email address</li>";

 * Function for validating Multiple email

function validate_email(email)
    var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;

     if (!filter.test(email))
             return false;
               return true;


Print this Page and Open New window in Drupal

 Use this printPage() and openWin() Function in your main js file and call this where ever you want to print a page and Opens in a new window popup respectively.

function printPage() {
    var agt = navigator.userAgent.toLowerCase();
    var is_win = ( (agt.indexOf("win")!=-1) || (agt.indexOf("16bit")!=-1) );
    var is_mac    = (agt.indexOf("mac")!=-1);
    var macos  = (is_mac && ((agt.indexOf("mac os") != -1) || (agt.indexOf("macos") != -1) ||;
    var macosx = (macos && ((agt.indexOf("os x") != -1) || (agt.indexOf("osx") != -1)));

    if(macosx || is_win ){
    } else {
        alert("To print this page, press 'command+P'.");

function openWin(theURL, windowName, features) {
    newWin =, windowName, features);

onclick="'<?php print base_path();?>privacy_page(your URI)','popup(Window name)','width=625,height=600,scrollbars=1'(features));

Then,cal this function in your module file:

** printPage() function is used to print a page

**openWin() is used to open a page in a new window,ther you can use the print option also
