enqueue script in wordpress plugin for specific hook - wordpress

Question

When custom php function is called, need to register and enqueue script from within that called function. Then the whole thing gets added to wp_footer hook.
the echoed div in code below shows up in the developer tool, but the script is not showing or even giving any errors, i.e.- if this were an issue with the file path, then there would be resource error, yes? Any comments as to why there wouldn't be an error in loading the script?
The code:
if(get_option('show_content')) {
function add_time() {
echo '<div id="txt">' . '</div>';
// add script tut pro word plugin dev ch12.3
function py_enqueue_script () {
wp_register_script( 'timescript', plugin_url('../time.js', __FILE__));
wp_enqueue_script( 'timescript');
} // end py_enqueue_script
add_action('wp_enqueue_scripts', py_enqueue_script);
} // end show add_time
add_action("wp_footer",add_time);
} // end if

Answer 1

Try this (spotted some syntax errors):
if(get_option('show_content')) {
function add_time() {
echo '<div id="txt">' . '</div>';
// add script tut pro word plugin dev ch12.3
function py_enqueue_script () {
wp_register_script( 'timescript', plugins_url('../time.js', __FILE__), false, null, false));
wp_enqueue_script( 'timescript');
} // end py_enqueue_script
add_action('wp_enqueue_scripts', 'py_enqueue_script');
} // end show add_time
add_action('wp_footer', 'add_time');
} // end if
Brackets on add_action custom action (i.E. 'add_time' instead of add_time).
Plugins URL Function goes plugins_url not plugin_url
