可以使用这样的简单JavaScript代码

else if (answer is TextAnswer)
                            {
                                this.Sourcecode.AppendLine("\t\t\t\t<textarea id='" + id + "' name='" + id + "' value='' style='position: absolute; "
                                                         + "top: " + top + "px; left: " + left + "px; height: " + height + "px; width: " + width + "px; "
                                                         + "visibility:hidden; z-index: 2; resize: none;'></textarea>");
