    r2.attr('transform','R45');

    r3.attr('transform','R90,140,60');
    // 移动至50,60点
    r1.attr('transform','T50,60');
    // 再移动一次,结果不会累加,只会是下面的结果覆盖上面的结果;
    // 而且变换的结果是transform="matrix(1,0,0,1,100,60)",把变换修订为变换矩阵;
    r1.attr('transform','T100,60');
    // transform不影响原来的属性值,这个x还是20
    console.log(r1.attr('x'));
    // s表示放大
    r2.attr('transform','S0.8,0.5');
    // 这样就把所有的transform清空了
//    r1.attr('transform','');
    // 输出<rect x="20" y="20" width="80" height="40" rx="0" ry="0" fill="#ff0000" stroke="#000" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);" transform="matrix(1,0,0,1,0,0)"></rect>
    console.log(r1.node);
}
