**在此仅提取方法，需要时可以直接调用相关方法**

/*定义控件*/
    var krpano = document.getElementById("krpanoSWFObject");
    /*获取变量*/
    var fov = Number(krpano.get("view.fov"));
    var hlookat = Number(krpano.get("view.hlookat"));
    var vlookat = Number(krpano.get("view.vlookat"));
    /*放大*/
     fov -= 10.0;
     krpano.set("view.fov", fov);
    /*缩小*/
     fov += 10.0;
     krpano.set("view.fov", fov);
    /*左旋转*/
     hlookat += 10.0;
     krpano.set("view.hlookat", hlookat);
    /*右旋转*/
     hlookat -= 10.0;
     krpano.set("view.hlookat", hlookat);
    /*上倾斜*/
     vlookat -= 10.0;
     krpano.set("view.vlookat", vlookat);
    /*下倾斜*/
     vlookat += 10.0;
     krpano.set("view.vlookat", vlookat);
    /*自动旋转*/
     krpano.set("autorotate.enabled", true);
    /*VR模式*/
     krpano.call("WebVR.enterVR();");
    /*全屏*/
     krpano.set("fullscreen", true);
    /*停止旋转*/
     krpano.set("autorotate.enabled", false);
    
     以上的方法如放大缩小是不带动画的，有卡顿的感觉。下面的方法利用setTimeout方法实现平滑过渡。
    
     /*放大*/
     krpano.set("fov_moveforce",-1);
     setTimeout("krpano.set('fov_moveforce',0)",200);
     /*缩小*/
     krpano.set("fov_moveforce",1);
     setTimeout("krpano.set('fov_moveforce',0)",200);
     /*左旋转*/
     krpano.set("hlookat_moveforce",-1);
     setTimeout("krpano.set('hlookat_moveforce',0)",200);
     /*右旋转*/
     krpano.set("hlookat_moveforce",1);
     setTimeout("krpano.set('hlookat_moveforce',0)",200);
     /*上倾斜*/
     krpano.set("vlookat_moveforce",-1);
     setTimeout("krpano.set('vlookat_moveforce',0)",200);
     /*下倾斜*/
     krpano.set("vlookat_moveforce",1);
     setTimeout("krpano.set('vlookat_moveforce',0)",200);
