Coding Standards for 3rd Party Plugins

A properly coded plugin should load all their scrips via wp_enqueue functions. And it should apply functionality via a inline scripts like this format targeting a unique class :

<div class="audioplayer-tobe ap_idx_2 apconfig-skinwave-small skin-wave ap772" style="" id="ap772"> [...] </div><script> jQuery(document).ready(function ($){ dzsap_init_functionality(".ap_idx_2",settings_ap); });
