无法读取cakephp 2中未定义的属性“ body”-TinyMCE

Question

tinymce.EditorManager.execCommand('mceRemoveEditor', true, "commentBox");

$('#commentBox').css("display:block");
tinymce.init({
    mode: "none",
    plugins: [
        "advlist autolink autosave link image lists charmap print preview hr anchor pagebreak spellchecker",
        "searchreplace wordcount visualblocks visualchars code fullscreen insertdatetime media nonbreaking",
        "table contextmenu directionality emoticons template textcolor paste textcolor colorpicker textpattern"
    ],
    toolbar1: "newdocument fullpage | bold italic underline strikethrough | alignleft aligncenter alignright alignjustify | styleselect formatselect fontselect fontsizeselect",
    toolbar2: "cut copy paste | searchreplace | bullist numlist | outdent indent blockquote | undo redo | link unlink anchor image media code | insertdatetime preview | forecolor backcolor",
    toolbar3: "table | hr removeformat | subscript superscript | charmap emoticons | print fullscreen | ltr rtl | spellchecker | visualchars visualblocks nonbreaking template pagebreak restoredraft",
    menubar: false,
    toolbar_items_size: 'small',
    style_formats: [
        {title: 'Bold text', inline: 'b'},
        {title: 'Red text', inline: 'span', styles: {color: '#ff0000'}},
        {title: 'Red header', block: 'h1', styles: {color: '#ff0000'}},
        {title: 'Example 1', inline: 'span', classes: 'example1'},
        {title: 'Example 2', inline: 'span', classes: 'example2'},
        {title: 'Table styles'},
        {title: 'Table row 1', selector: 'tr', classes: 'tablerow1'}
    ],
    templates: [
        {title: 'Test template 1', content: 'Test 1'},
        {title: 'Test template 2', content: 'Test 2'}
    ]
});
tinymce.EditorManager.execCommand('mceAddEditor', true, "commentBox");
closeModal();

我使用此代码，但TinyMCE无法正常工作，并且在控制台中看到错误，

请告诉我为什么代码不起作用，怎么办？
