I am using this, but I don't understand why it's not working.
if ($_SERVER['REQUEST_URI'] == '/node/1') {
drupal_add_js(drupal_get_path('theme', 'sanskrit').'/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js', 'inline');
drupal_add_js('/sites/all/themes/sanskrit/scripts/scripts/jquery.nivo.slider.pack.js');
}
What I want to do is adding specific JavaScript files when the user is viewing the front page.
This should do it:
function MYTHEME_preprocess_page(&$vars) {
if (drupal_is_front_page()) {
drupal_add_js(drupal_get_path('theme', 'MYTHEME') . '/MYSCRIPTS/myscript.js');
$vars['scripts'] = drupal_get_js();
}
}
FYI: You'd use drupal_get_js in case any modules are also using hook_preprocess_page and setting new scripts themselves.
Also, I wouldn't just add a newer version of jQuery in willy nilly. Try either jQuery Update or jQuery Multi
Undefined function error? I guess it should be drupal_is_front_page() like my answer below.

Alternately: The JavaScript Libraries module. It doesn't let you limit the script to the front page, but is certainly much easier than writing a module just to load a script.
If you are working with a module, you put it in hook_init like this:
function mymodule_init() {
if(drupal_is_front_page()) {
drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js');
drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/scripts/jquery.nivo.slider.pack.js');
}
}
If you want to put it in preprocess_page:
function yourTheme_preprocess_page(&$vars) {
if(drupal_is_front_page()) {
drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js');
drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/scripts/jquery.nivo.slider.pack.js');
$vars['scripts'] = drupal_get_js();
}
}
Or you can put it in your theme.info file if you are building your own theme.
scripts[] = scripts/jquery.nivo.slider.pack.js
The best and simplest means to accomplish adding javascript to a front page is via context and context add assets. Context and context add assets are exportable as well and you can create a feature to be used later on.
More about context add assets:
This module will add a reaction within context to add theme, module, or custom folder files to your page(s).
Ever wanted to quickly add a css file to a theme? Include a js file on only one page (or section?)
Make using multiple CSS files a breeze with this module and harness the power of Context in your theme!
It is not working because you are concatenating the string returned from drupal_get_path('theme', 'sanskrit') with '/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js'; supposing that you didn't install Drupal in a sub-directory of the server root directory, the filename you are passing to drupal_add_js() is sites/all/themes/sanskrit/bbbsites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js.
The code you should use is the following one.
if ($_SERVER['REQUEST_URI'] == '/node/1') {
$theme_path = drupal_get_path('theme', 'sanskrit');
drupal_add_js($theme_path . '/scripts/jquery-1.4.3.min.js', 'inline');
drupal_add_js($theme_path . '/scripts/jquery.nivo.slider.pack.js');
}
As others pointed out, to check if the user is viewing the front page, you just call drupal_is_front_page().
Paths like sites/all/themes should be never hard coded in a theme/module code, as a theme could be installed in sites/<domain.name>/themes/<theme.name>, and a module could be installed in sites/<domain.name>/modules/<module.name>. Suppose that the Drupal installation is used for the domain blog.example.com, the Views module could be installed in sites/blog.example.com/modules/views, and a theme like the Whitebull theme could be installed in sites/blog.example.com/themes/whitebull.
