        $(editorDom).keydown(function (e) {
            var code;
            if (!e) {
                var e = window.event;
            }
            if (e.keyCode) {
                code = e.keyCode;
            }
            else if (e.which) {
                code = e.which;
            }
            if (e.ctrlKey && code == 88 || e.ctrlKey && code == 86) {
                return;
            }//出自http://www.cnblogs.com/ahjesus 尊重作者辛苦劳动成果，转载请注明出处，谢谢！
            if (code == 8 || code == 13 || code == 32 || code == 46 || (code >= 48 && code <= 57) || (code >= 65 && code <= 90) || (code >= 96 && code <= 107) || (code >= 109 && code <= 111) || (code >= 186 && code <= 192) || (code >= 219 && code <= 222)) {
                var deviant = 0;
                if (code == 8) {
                    deviant = -deviant;
                }
                _this.Func_saveErrorPoints(editorDom);
                //_this.Func_disposeErrorPoints(p_errorsArr, deviant);
            }
        });
