Javascript无法在php中正常工作

I am creating a pop up.I am using fancybox ,it is working fine when I include it normally in html as:

<script type="text/javascript">
    $(document).ready(function($){
       $.fancybox.open([{
          content: $('<a href="http://www.google.com" target="_blank">Gmail</a>')
       }]); 
    });
</script>

But when i write the same quote in drupal_add_js its not working:

drupal_add_js('jQuery(document).ready(function(){
       $.fancybox.open([{
          content: $("<a href=\'http://www.google.com\' target=\'_blank\'>Gmail</a>")
       }]); 
    });','inline');

I am passing it as inline java script,someone can tell me what is the error due to which its happening.I have included the fancybox js and css.

I believe drupal set noConfilct on jQuery so you'll have to set the parameter of the ready function to $

drupal_add_js('jQuery(document).ready(function($){
       $.fancybox.open([{
          content: $("<a href=\'http://www.google.com\' target=\'_blank\'>Gmail</a>")
       }]); 
});','inline');

It finally worked for me. I explicity called the js file using drupal_Add_js function and rest all code was same. Its working absolutely fine as required by me. Thanks a lot for help.

drupal_add_js('jquery.fancybox.js');
            drupal_add_js('http://code.jquery.com/jquery-1.7.2.js');
            drupal_add_js('jQuery(document).ready(function(){
       $.fancybox.open([{
          content: $("<a href=\'http://www.google.com\' target=\'_blank\'>Gmail</a>")
       }]); 
});', 'inline');
