javascript - 如何创建一个插件来在 Adob​​e CQ 5 的富文本编辑器中添加附件或文件？

Question

我需要帮助在 Adob​​e cq 5 中创建富文本编辑器插件，以将图像、pdf、视频、ppt 或任何文件添加到富文本编辑器中。

现有的可用 rte 插件有 findreplace、undo、拼写检查、table 等

如何创建一个插件来将文件添加到富文本编辑器？ 插件是一个 ext js 文件。如果有人能提出答案，我将不胜感激。这将会有很大的帮助。

谢谢

我在 RTE 中添加了一个自定义下拉菜单。它用于在从中选择值时向编辑器添加值。我认为这可能会帮助您解决您的问题，因为同样您可以创建所需的插件。 请引用方法旁边的注释供您引用。

/**

var keyvalueEnteries = [];
var newText;
var doc;
var range

CUI.rte.plugins.PlaceholderPlugin = new Class({

    toString: "PlaceholderPlugin",

    cachedFormats: null,

    /**

    getFeatures: function() {
        return [ "Myparaformat" ];
    },

        var com = CUI.rte.Common;

            this.cachedFormats = this.config.formats || { };
            com.removeJcrData(this.cachedFormats);
            this.cachedFormats = com.toArray(this.cachedFormats, "tag", "description");
        }
        return this.cachedFormats;
    },


    initializeUI: function(tbGenerator) {

        var plg = CUI.rte.plugins;
        var ui = CUI.rte.ui;
        if (this.isFeatureEnabled("placeHolder")) {
            this.formatUI = tbGenerator.createParaFormatter("placeHolder", this,null,this.getKeys());

            tbGenerator.addElement("placeHolder", plg.Plugin.SORT_PARAFORMAT, this.formatUI,
                    10);

    notifyPluginConfig: function(pluginConfig) { //This function gets executed once on load of RTE for the first time

        var url = pluginConfig.sourceURL;

        keyvalueEnteries = CQ.HTTP.eval(url);

        keyvalueEnteries = JSON.stringify(keyvalueEnteries);

                    range.insertNode(placeholderElement); //INSERTS PLACEHOLDER AT CURRENT CARET LOCATION
                    range.setStartAfter(placeholderElement);//INSERTS CURSOR AT THE END OF CURRENT PLACEHOLDER IF PLACEHOLDER IS SELECTED AGAIN
                }
            }
        }
    },

    updateState: function(selDef) { // This function gets executed on click on the editor space in RTE
        doc = selDef.editContext.doc; //GET THE DOCUMENT INSIDE THE IFRAME
