data：

这个deg是我所需要的！！！

var _this = this       var deg = _this.data.deg       var GTshow = _this.data.GTshow       if (!GTshow) {         var My = setInterval(() => {           if (_this.data.deg > -90) {             _this.setData({               deg: _this.data.deg - 10             })           } else {             if (_this.data.bottom01 < 150) {               _this.setData({                 bottom01: _this.data.bottom01 + 5,                 bottom02: _this.data.bottom02 + 10,                 opacity: _this.data.opacity + 0.05               })             } else if (_this.data.opacity < 1) {               _this.setData({                 opacity: _this.data.opacity + 0.05               })             } else {               clearInterval(My)               _this.setData({                 GTshow: true               })             }           }         }, 10)       } else {         var Me = setInterval(() => {           if (_this.data.deg < 0) {             _this.setData({               deg: _this.data.deg + 10             })           } else {             if (_this.data.bottom01 > 100) {               _this.setData({                 bottom01: _this.data.bottom01 - 5,                 bottom02: _this.data.bottom02 - 10,                 opacity: _this.data.opacity - 0.05               })             } else if (_this.data.opacity > 0) {               _this.setData({                 opacity: _this.data.opacity - 0.05               })             } else {               clearInterval(Me)               _this.setData({                 GTshow: false               })             }           }         }, 10)       }     }
