感谢您的帮助，但没有任何帮助.我找到了自己的解决方案，并且觉得需要共享它，因为我只找到了过时的解决方案，这是行不通的:(.

Thanks for the help, but nothing worked. I found my own solution, and I felt like sharing this was needed, because I only found outdated solutions, that did not work :(.

解决方案:

在您的TinyMCE初始化中，添加以下代码:

In your TinyMCE init add following code:

    tinyMCE.init({
// General options
        elements: elementid,
        setup: function (ed) {
            ed.onKeyUp.add(function (ed, e) {
                actualCaretPositionBookmark = tinyMCE.activeEditor.selection.getBookmark();
            });
            ed.onClick.add(function (ed, e) {
                actualCaretPositionBookmark = tinyMCE.activeEditor.selection.getBookmark();
            }); 
        }

其中"actualCaretPositionBookmark"是javascript中的全局变量，您所有的javascript代码都可以访问

Where "actualCaretPositionBookmark" is a global variable in javascript that can be accesed by all your javascript code

然后，当您想通过javascript将文本添加到TinyMCE编辑器中时，添加以下代码:

Then when you want to add text into your TinyMCE editor via javascript, add following code:

                if (tinymce.isIE) {
                tinyMCE.activeEditor.selection.moveToBookmark(actualCaretPositionBookmark);
                tinyMCE.execCommand('mceInsertContent',false, 'My new text'); 

            }else {
                tinyMCE.execCommand('insertHTML',false, 'My new text'); 
            }
