How to disable the event that is executed before leaving the page?

Question

I'm building a plugin for wordpress, I have a custom post type and several meta-boxes. In a meta-box I have a button to publish or update custom.

This is something of my code:

add_meta_box(
    'my_meta_boz'
    ,__( 'My title meta box', 'my-plugin' )
    ,array( $this, 'render_my_meta_box' )
    ,'my-screen'
    ,'normal'
    ,'high'
);

In my 'render_my_meta_box' function I have my custom button:

<p>
    <input type="submit" name="publish" id="publish" value="Save changes" />
</p>

And I have no problem with that, except that saving or updating shows a confirmation dialog.

I want to remove this dialog box because the original button does not show any confirmation. How can I delete this dialog?

Try the following, but it did not work:

<input type="submit" name="publish" id="publish" value="Save changes" onclick="javascript:window.onbeforeunload = null;"/>

I have also used the 'submit_button ()' function, but it also shows the confirmation dialog.

You can try this solution, it is not very clean but it works. Call the event click on the original button.

<input type="submit" value="Save changes" onclick="window.document.getElementById('publish').click();"/>
