| F16945647: wikipage content fired twice with live updates cropped.png | |
| Apr 13 2018, 4:40 AM |
mw.hook( 'wikipage.content' ).add( function() { 'use strict'; console.log( 'wikipage.content fired' ); } );
to Special:MyPage/common.js
It should be clear from the timing that wikipage.content is fired twice every time a new element is added.
Screenshot:
The hook callback receives $elements as the first arguments. It is fired once with the new list of changes as $elements and once with the updated options form.
If you have a user script that enhances any of these parts, you can inspect $elements to check if it's appropriate for it to run.
Ah, I see! So I have to change my code to
mw.hook( 'wikipage.content' ).add( function( elements ) { 'use strict'; if ( elements.hasClass( 'mw-changeslist' ) ) { console.log( 'wikipage.content fired' ); } } );
Thank you!
