IE浏览器提示对象不支持“append”属性或方法

如下代码在IE浏览器中无法执行，提示对象不支持“append”属性或方法

    var tImg = document.createElement("img");
            tImg.setAttribute("src", src);
            tImg.setAttribute("class", "img-rounded");

            var tBr = document.createElement("br");

            var tName = document.createElement("span");
            tName.innerText = $(data).attr("name");
            tName.style = "font-size:12px;font-family:sans-serif;font-weight:700;";

            var tDiv = document.createElement("div");
            tDiv.setAttribute("class", "col-xs-6 col-sm-4 col-md-2 col-lg-2 text-center");
            tDiv.append(tImg, tBr, tName);

            $("#content").append(tDiv);

做如下修改，就可以了

  var tImg = "<div class='col-xs-6 col-sm-4 col-md-2 col-lg-2 text-center'><img src='"
                + src + "' class='img-rounded' /><br/><span style='font-size:12px;font-family:sans-serif;font-weight:700;'>"
                + $(data).attr("name") + "</span></div>"

            $("#content").append(tImg);
