Adobe SVG View 动态修改src的问题

                    var embedTag = document.getElementById("embed1");
                    var oParent = embedTag.parentNode;
                    oParent.removeChild(embedTag);
                    var oEmbed = document.createElement('embed');
                    oEmbed.src = "TreeInfo.aspx?ID=" + node.id + '.svg';
                    oEmbed.width = "800";
                    oEmbed.height = "600";
                    oEmbed.id = "embed1";

                    oParent.appendChild(oEmbed);
