tinyMCE添加自定义快捷方式

Question

我为我的tinymce添加了一个自定义快捷方式，但是当我按下快捷键alt + p时，我得到一个错误，看来我的对象在“p.getDoc（）上是空的.execCommand（）

这是我的初始代码：

    page.ClientScript.RegisterStartupScript(
        page.GetType(),
        "MyKey2" + this.ID, @"<script type=""text/javascript"" >" +
        @"tinyMCE.init({" +
        @"mode: ""exact""," +
        @"elements: """ + this.ID + @"""," +
        @"theme: ""advanced""," +
        @"theme_advanced_buttons1: ""bold,italic,underline,|,outdent,indent,|,cut,copy,paste,|,undo,redo""," +
        @"theme_advanced_toolbar_location: ""top""," +
        @"theme_advanced_toolbar_align: ""left""," +
        @"theme_advanced_statusbar_location: ""bottom""," +
        "custom_shortcuts : true," +
        "theme_advanced_path : false," +
        "setup : function(ed) {" +
            "ed.onInit.add(function(ed) {"+
            "ed.addShortcut('alt+p',' ','CutFromJournal();', ' ');"+   
        "});"+
        "}" +
        "});" +
        "</script>",
false);

我也试过直接在js文件中创建方法

    function addKeyboardShortcuts() {
        // Add some inline shortcuts
        ed.addShortcut('ctrl+b', 'bold_desc', 'Bold');
        ed.addShortcut('ctrl+i', 'italic_desc', 'Italic');
        ed.addShortcut('ctrl+u', 'underline_desc', 'Underline');

        //custom shortcuts - 
        ed.addShortcut('ctrl+p', 'custom_description', 'CutFromJournal');

        // BlockFormat shortcuts keys
        for (var i = 1; i <= 6; i++) {
            ed.addShortcut('ctrl+' + i, '', ['FormatBlock', false, 'h' + i]);
        }

        ed.addShortcut('ctrl+7', '', ['FormatBlock', false, 'p']);
        ed.addShortcut('ctrl+8', '', ['FormatBlock', false, 'div']);
        ed.addShortcut('ctrl+9', '', ['FormatBlock', false, 'address']);
    };
