Javascript tinymce setcontent使现有的内容消失

我正试图添加一些额外的隐藏内容到tinymce编辑器使用

tinyMCE.get（'addCustom_id'）.setContent（数据）

在事件上执行上述行后，setContent之前的现有内容将消失。我希望保留现有内容并添加额外内容。请帮助

下面是以下tinymce初始化代码

tinymce.init({
    mode : "specific_textareas",
    selector : '#customArea textarea',
    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 fullpage textcolor"
    ],

    toolbar1: "newdocument fullpage | bold italic underline strikethrough | alignleft aligncenter alignright alignjustify | styleselect  fontselect fontsizeselect",
    toolbar2: "searchreplace | bullist numlist | outdent indent blockquote | undo redo | link unlink anchor image media code | inserttime preview | forecolor backcolor",
    toolbar3: "table | hr removeformat | subscript superscript | charmap emoticons | print fullscreen | ltr rtl | spellchecker | visualchars visualblocks nonbreaking template pagebreak restoredraft",

    {title: "Header 2", inline: "h2"},
    {title: "Header 3", inline: "h3"},
    {title: "Header 4", inline: "h4"},
    {title: "Header 5", inline: "h5"},
    {title: "Header 6", inline: "h6"}
]},

    {title: "Pre", format: "pre"}
]},
{title: "Alignment", items: [

    {title: "Center", icon: "aligncenter", format: "aligncenter"},
    {title: "Right", icon: "alignright", format: "alignright"},
    {title: "Justify", icon: "alignjustify", format: "alignjustify"}
]}
    ]

setContent
重置整个编辑器内容

你可以用

tinyMCE.get('addCustom_id').execCommand('insertHTML', false, data);

在编辑器中的当前插入符号位置添加内容。
实际选择将被替换。
很高兴能够提供帮助，但我不会使用
tinyMCE.get（'addCustom\u id'）
将添加的内容取回，即使它在tinyMCE的视图源代码中？？使用tinyMCE.get（'addCustom\u id'），您将获得编辑器实例。要获取编辑器内容，请使用tinyMCE.get（'addCustom_id'）.getContent（）；
