wordpress - How to avoid double inclusion of Bootstrap.js? -

we've been developing wordpress theme , stumbled on weird problem. popup displayed bootstrap.js appears fraction of second , disappears. after thorough research have figured out problem caused plugin uses bootstrap.js. 2 bootstrap.js loaded, 1 our theme , plugin. how avoid conflict?

the solution check if bootstrap.js enqueued. i've added following functions.php of theme:

function enqueue_scripts() {     // check if bootstrap there     $bootstrap_enqueued = false;     foreach( $wp_scripts->registered $script ) {         if ((stristr($script->src, 'bootstrap.min.js') !== false or              stristr($script->src, 'bootstrap.js') != false) ,             wp_script_is($script->handle, $list = 'enqueued')) {              $bootstrap_enqueued = true;             break;         }     }      if (!$bootstrap_enqueued) {         wp_enqueue_script( 'theme-bootstrap-js', get_template_directory_uri() . '/js/bootstrap.min.js', array(), '2015', true ); }  // note last parameter. it's important last in list of hooks add_action( 'wp_enqueue_scripts', 'enqueue_scripts', php_int_max );`
