我对 tinymce 和 UpdatePanel 有疑问，我发布这个是因为没有其他解决方案对我有用。

这是我的代码：

function pageLoad() {

        console.log("pageLoad called");
        tinyMCE.init({
            theme: "advanced",
            plugins: "preview,paste",
            theme_advanced_toolbar_location: "top",
            theme_advanced_toolbar_align: "left",
            theme_advanced_buttons1: "undo,redo,|,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,|,fontselect,fontsizeselect,forecolor,backcolor",
            theme_advanced_buttons2: "cut,copy,paste,pastetext,pasteword,|,link,unlink,|,removeformat,cleanup,preview",
            theme_advanced_buttons3: ""
        });

        var prm = Sys.WebForms.PageRequestManager.getInstance();
        prm.add_beginRequest(function (sender, args) {
            var inst = tinyMCE.getInstanceById('<%= txtContenidoCorreo.ClientID %>');
            if (typeof inst !== 'undefined' && inst !== null) {
                console.log('removing');
                //tinyMCE.triggerSave();
                //tinyMCE.execCommand('mceFocus', false, '<%= txtContenidoCorreo.ClientID %>');
                tinyMCE.execCommand('mceRemoveControl', false, '<%= txtContenidoCorreo.ClientID %>');
                console.log('removed');
            }

        });

        prm.add_endRequest(function (sender, args) {
            var inst = tinyMCE.getInstanceById('<%= txtContenidoCorreo.ClientID %>');
            if (!inst) {
                console.log('initializing');
                tinyMCE.execCommand('mceAddControl', false, '<%= txtContenidoCorreo.ClientID %>');
                console.log('initialized');
            }
        });
    }

经过几个异步请求后，我在 IE9 和 IE10 中收到此错误：

SCRIPT70：权限被拒绝。

发生此错误的确切行是：

result = this.bodyElement || this.getDoc().body;

这是堆栈跟踪：

getBody@/JavaScript/tiny_mce/tiny_mce_src.js:14548:11

获取内容@/JavaScript/tiny_mce/tiny_mce_src.js:14458:30

保存@/JavaScript/tiny_mce/tiny_mce_src.js:14377:4

{匿名}()@(/JavaScript/tiny_mce/tiny_mce_src.js:13466:17)

dispatch@/JavaScript/tiny_mce/tiny_mce_src.js:562:4

eventHandler@/JavaScript/tiny_mce/tiny_mce_src.js:14905:5

executeHandlers@/JavaScript/tiny_mce/tiny_mce_src.js:4731:6

我正在使用 Tinymce 3.5.8
