第一次跳转到页面setData能正常渲染，退出页面重新进入后setData渲染无效。日志打印是已经执行了这段代码。

//自动模式

if (app.getPattern() == 1) {

console.log(“自动”);

that.setData({

autBackageColor: that.data.modeOpen,

modeBackageColor: that.data.defaultColor,

disabled: true

});

}

//手动模式

else if (app.getPattern() == 0) {

console.log(“手动”);

that.setData({

autBackageColor: that.data.defaultColor,

modeBackageColor: that.data.modeOpen,

disabled: false

});

}
