Question

I am using jQuery sharrre plugin in my site. but there is a problem.
I want to change a default variable of plugin, and how to do it outside the plugin code .

There is a default variable in plugin code

urlCurl: 'sharrre.php',  //PHP script for google plus...

is it possible to set this var outside the plugin like this:

jQuery(function(){
  defaults = {
    urlCurl: '<?php echo get_template_directory() . '/inc/sharrre.php' ?>'
    }
});

This is sharrre plugin code

You should read the plugin documentation, but just based on looking at the syntax it seems like you want to use this:

$("selector").sharrre({urlCurl: '/path/inc/sharrre.php'});

I cannot advocate the mixing of PHP and JavaScript. Get the correct path part by adding it to the DOM somehow, perhaps with <base>.
