Adding JS function as third parameter in do_action

2 Views

I have this JS function named as “myjsfunction()”. 

function myjsfunction() {

jQuery('#html_admin_show').hide();
jQuery('#html_admin_edit').show();

}

One limitation is that I cannot edit the original JS function like to put some PHP tags, etc.

How is it possible to call this JS function inside a WordPress do_action hook?

I’m preferring to add it as third parameter because I’m already using the second parameter, so something like: 

do_action('myhelp', 'mysecondfunction', 'myjsfunction');

But it is not showing the element #html_admin_edit when the page runs. Any ideas how to call this function?

Thanks.

  1. First, your callback must be PHP:

    function myjsfunction_callback() {
?>
<script>myjsfunction();</script>
<?php
}

    Second, you can add multiple callbacks to one action:

    add_action( 'myhelp', 'myjsfunction_callback' );
add_action( 'myhelp', 'mysecondfunction' );

    Now, you can call do_action() without parameter …

    do_action( 'myhelp' );

    … and both callbacks will be executed.

    I reply to your comment: You can use just one callback:

    do_action( 'myhelp', 'mysecondfunction', 'myjsfunction_callback' );

    You have to use a rather abstract callback then, and accept more parameters:

    add_action( 'myhelp', 'multicall', 10, 99 );

function multicall()
{
    $functions = func_get_args();

    foreach ( $functions as $function )
    {
        if ( function_exists( $function ) )
            $function();
    }
}

    Now you can pass up to 99 function names, and all of them will be executed for that action.
