ここで少しテストしてください.

jquery-migrate.js をのぞいて、この部分に気づきました:

 // Set to true to prevent console output; migrateWarnings still maintained
// jQuery.migrateMute = false;
 

そこで、新しく wp_add_inline_script() <を使用して以下をテストしました./a>、バージョン4.5で導入:

 add_action( 'wp_enqueue_scripts', function()
{   
    wp_add_inline_script( 
        'jquery-migrate', 'jQuery.migrateMute = true;',
        'before' 
    );
} );
 

 // Show a message on the console so devs know we're active
if ( window.console && window.console.log ) {
    window.console.log( "JQMIGRATE: Migrate is installed" +
        ( jQuery.migrateMute ? "" : " with logging active" ) +
        ", version " + jQuery.migrateVersion );
}
 

I peeked into jquery-migrate.js and noticed this part:

// Set to true to prevent console output; migrateWarnings still maintained
// jQuery.migrateMute = false;

so I tested the following with the newly wp_add_inline_script(), introduced in version 4.5:

add_action( 'wp_enqueue_scripts', function()
{   
    wp_add_inline_script( 
        'jquery-migrate', 'jQuery.migrateMute = true;',
        'before' 
    );
} );

This will change:

JQMIGRATE: Migrate is installed with logging active, version 1.4.0

to:

JQMIGRATE: Migrate is installed, version 1.4.0

So it doesn't actually prevent all console output, like this part in jquery-migrate.js:

// Show a message on the console so devs know we're active
if ( window.console && window.console.log ) {
    window.console.log( "JQMIGRATE: Migrate is installed" +
        ( jQuery.migrateMute ? "" : " with logging active" ) +
        ", version " + jQuery.migrateVersion );
}

解決策:

これをfunctions.phpに追加します:

 function remove_jquery_migrate_notice() {
    $m= $GLOBALS['wp_scripts']->registered['jquery-migrate'];
    $m->extra['before'][]='temp_jm_logconsole = window.console.log; window.console.log=null;';
    $m->extra['after'][]='window.console.log=temp_jm_logconsole;';
}
add_action( 'init', 'remove_jquery_migrate_notice', 5 );
 

jquery-migrateが標準フック(<link rel=stylesheet....>を出力)で呼び出され、load-scripts.phpをまとめて(admin-dashboardのように)

Solution:

add this to functions.php:

function remove_jquery_migrate_notice() {
    $m= $GLOBALS['wp_scripts']->registered['jquery-migrate'];
    $m->extra['before'][]='temp_jm_logconsole = window.console.log; window.console.log=null;';
    $m->extra['after'][]='window.console.log=temp_jm_logconsole;';
}
add_action( 'init', 'remove_jquery_migrate_notice', 5 );

It works when jquery-migrate is called with standard hook (which outputs <link rel=stylesheet....>) and not with load-scripts.php in bulk (like in admin-dashboard).

同じ問題が発生し、SCRIPT_DEBUGでfalseをwp-config.phpに設定するだけでよいことがわかりました.これが誰かに役立つことを願っています

Had the same problem, and found out you just need to set SCRIPT_DEBUG to false in your wp-config.php. Hope this helps someone

Andyが前述したように WordPressはjQuery移行スクリプトを使用して下位互換性を確保します .これが、デフォルトで自動的に読み込まれる理由です.

これは、JQuery Migrateモジュールを削除して、クライアント側でのページの読み込みを高速化しながら、煩わしいJQMIGRATE通知を取り除く安全な方法です.このコードをコピーしてfunctions.php ファイルに貼り付けるだけで、完了です.

 <?php
/**
 * Disable jQuery Migrate in WordPress.
 *
 * @author Guy Dumais.
 * @link https://en.guydumais.digital/disable-jquery-migrate-in-wordpress/
 */
add_filter( 'wp_default_scripts', $af = static function( &$scripts) {
    if(!is_admin()) {
        $scripts->remove( 'jquery');
        $scripts->add( 'jquery', false, array( 'jquery-core' ), '1.12.4' );
    }    
}, PHP_INT_MAX );
unset( $af );

As mentionned previously by Andy WordPress uses the jQuery migrate script to ensure backwards compatibility and this is why it is automatically loaded by default.

Here's a safe way to remove the JQuery Migrate module and thus get rid of the annoying JQMIGRATE notice while speeding up the loading of your page on the client side. Simply copy/paste this code in your functions.php file and you're done:

<?php
/**
 * Disable jQuery Migrate in WordPress.
 *
 * @author Guy Dumais.
 * @link https://en.guydumais.digital/disable-jquery-migrate-in-wordpress/
 */
add_filter( 'wp_default_scripts', $af = static function( &$scripts) {
    if(!is_admin()) {
        $scripts->remove( 'jquery');
        $scripts->add( 'jquery', false, array( 'jquery-core' ), '1.12.4' );
    }    
}, PHP_INT_MAX );
unset( $af );
