Comment sélectionner le contenu dans la vue texte textrea dans wp_editor?

Question

J'essaie de compter les mots parmi d'autres statistiques textuelles saisies dans l'éditeur de publication par défaut (wp_editor).

Il est supposé que le mot d'écriture compte dans <div id = "Nombre de mots">dans la boîte de méta juste en dessous de wp_editor.

J'ai pu sélectionner correctement l'éditeur visuel copiermais pas l'éditeur de texte copier.

J'ai inclus tout le code ci-dessous. Le javascript en question est inclus dans les commentaires "Begin" et "End".

Merci pour votre aide, Tim

Structure du répertoire du plugin:

plugin-Shell > plugin-Shell.php
plugin-Shell > assets > js > admin > wordcount.js
plugin-Shell > assets > css > admin > style.css
plugin-Shell > assets > css > frontend > style.css

Feuille de style d'administration:

#after_editor-sortables {
    padding-top: 40px;
}
#wordcount {
    background-color: #fff;
    color: #000;
    border-color: #525252;
    border-style: solid;
    border-width: 5px;
    padding: 5px;
    width: 50px;
}

Javascript:

var i=0;
jQuery(document).ready(function($){
    setInterval(function(){
        var replacedTags = "";
        var replacedEntities = "";
        var tinymcevalue = "";

        console.log('Text: ' + tinymcevalue);
        console.log('Display: ' + $('textarea#content').css('display'));

        // BEGIN

        if($('textarea#content').css('display') == 'none'){ 
            tinymcevalue =    $('#content_ifr').contents().find('#tinymce').html(); 
        } else { 
            tinymcevalue = $('textarea#content').contents(); // Failed
         // tinymcevalue = $('textarea#content').html();     // Failed
        }

        // END

        var regexTags = /<[^>]+>/g;
        var regexEntities = /&lt;[\s\S]+?&gt;/gi;
        if (tinymcevalue !== "") {    
            replacedTags = tinymcevalue.replace(regexTags , "");
            replacedEntities = replacedTags.replace(regexEntities , "");
        }

        var wordscount = replacedEntities.split(" ");

        $("#wordcount").text(wordscount.length);
    }, 5000)

L'éditeur TinyMCE a des fonctions dans son API pour obtenir le contenu de l'éditeur. Pour obtenir tout le contenu de la sélection, utilisez la source suivante:

tinyMCE.activeEditor.selection.getContent();

WordPress a depuis 4.3 beaucoup de changements dans l'éditeur. Utilisez toujours l’API 4 pour trouver les bonnes fonctions dans la page de documentation. Ici pour la documentation sur l'obtention de contenu dans l'éditeur. Toutes les fonctions utiles de l'API vous trouvent dans ce lien ci-dessous.

Pour obtenir tout le contenu, utilisez tinymce.activeEditor.selection.getNode().

Pour l'utilisation dans l'environnement WordPress, vous pouvez également utiliser jQuery, est une partie du noyau. Comme exemple, créez une instance de tinymce et ajoutez votre source.

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

    tinymce.PluginManager.add( 'Your_Namespace', function( editor ) {

                if ( typeof(
                        tinymce.activeEditor.selection.getContent()
                    ) != 'undefined' ) {
                    marked = true;
                }

                if ( marked == true ) {
                    var content       = tinymce.activeEditor.selection.getContent(),
                        start_content = tinymce.activeEditor.selection.getStart().nodeName,
                        all           = tinymce.activeEditor.selection.getNode()
                }

                // Debug in Console
                console.log(all);

    } );
} );
