要将我们的按钮添加到TinyMCE编辑器，我们需要做以下几件事：

将我们的按钮添加到工具栏中注册一个TinyMCE插件创建一个TinyMCE插件，该插件告诉TinyMCE单击按钮时要做什么

步骤#1和#2

在这些步骤中，我们注册了我们的TinyMCE插件，该插件将位于\'path/to/shortcode.js\' （参见wpse72394_register_tinymce_plugin() （见下文）

 // init process for registering our button
 add_action(\'init\', \'wpse72394_shortcode_button_init\');
 function wpse72394_shortcode_button_init() {

      //Abort early if the user will never see TinyMCE
      if ( ! current_user_can(\'edit_posts\') && ! current_user_can(\'edit_pages\') && get_user_option(\'rich_editing\') == \'true\')
           return;

      //Add a callback to regiser our tinymce plugin   
      add_filter("mce_external_plugins", "wpse72394_register_tinymce_plugin"); 

      // Add a callback to add our button to the TinyMCE toolbar
      add_filter(\'mce_buttons\', \'wpse72394_add_tinymce_button\');
}


//This callback registers our plug-in
function wpse72394_register_tinymce_plugin($plugin_array) {
    $plugin_array[\'wpse72394_button\'] = \'path/to/shortcode.js\';
    return $plugin_array;
}

//This callback adds our button to the toolbar
function wpse72394_add_tinymce_button($buttons) {
            //Add the button ID to the $button array
    $buttons[] = "wpse72394_button";
    return $buttons;
}

现在我们需要创建TinyMCE插件。这将被归档\'path/to/shortcode.js\' （如早期步骤中所述）。

jQuery(document).ready(function($) {

    tinymce.create(\'tinymce.plugins.wpse72394_plugin\', {
        init : function(ed, url) {
                // Register command for when button is clicked
                ed.addCommand(\'wpse72394_insert_shortcode\', function() {
                    selected = tinyMCE.activeEditor.selection.getContent();

                    if( selected ){
                        //If text is selected when button is clicked
                        //Wrap shortcode around it.
                        content =  \'[shortcode]\'+selected+\'[/shortcode]\';
                    }else{
                        content =  \'[shortcode]\';
                    }

                    tinymce.execCommand(\'mceInsertContent\', false, content);
                });

            // Register buttons - trigger above command when clicked
            ed.addButton(\'wpse72394_button\', {title : \'Insert shortcode\', cmd : \'wpse72394_insert_shortcode\', image: url + \'/path/to/image.png\' });
        },   
    });

    // Register our TinyMCE plugin
    // first parameter is the button ID1
    // second parameter must match the first parameter of the tinymce.create() function above
    tinymce.PluginManager.add(\'wpse72394_button\', tinymce.plugins.wpse72394_plugin);
});
