[wp-hackers] Optimize wp_register_script and, wp_enqueue_script functions

[zhaiziming at gmail.com]

Thank you for both comments. The problem of these solutions is that developer or blogger have to go through the plugin code and write a filter function by themselves. The shortcode solution is better, but in some cases you can't put all js files in the footer.
Would be better to let plugin authors to do this, and bind (or register) js files to specific pages not all?

Thanks,

Ziming Zhai
