为什么我的 onload 在 Wordpress 中不起作用？

Question

I really need to use a onload and I don't understand why it's not working. I made a code snippet to test it out and yet again found that it didn't work. Is wordpress doing this? Or am I making a mistake? I found that events such as onclick and onchange are working.

function do_onload_event()
{
    return '<div id="loadevent" onload="do_show_event(event)"></div>' . '<script>
    function do_show_event(event)
    {
        console.log("on load event");
    }
    </script>';
}
add_shortcode('on_load_event','do_onload_event');

IMHO - Calling onload from in-post shortcode could have many issues of timing or executions. Also, I am not sure that it is possible ot hook to onLoad() or onready() more than once so it would be more compatible..

Since we are dealing with wordpress, you could try another approach using jQuery:

function add_my_scripts() {
    wp_enqueue_script( 'jquery' );
    wp_enqueue_script( 'my_init_script', 'MyScriptSource/etc', 'jquery', '1.0' ); // jQuery dependency
}
add_action( 'init', 'add_my_scripts' );

Then add another script that calls your method.

jQuery.noConflict();

jQuery(document).ready(function($) {
    init();
});

You could of course try also for load event

jQuery(window).load(function($) {
   // your function
});

or..

(function($) {
  // your function
})(jQuery);
