js代码：


  beforeMount() {
    const self = this;
    wx.getSystemInfo({
      success(system) {
        console.log(`system:`, system);
        self.statusBarHeight = system.statusBarHeight;
        self.platform = system.platform;

        let platformReg = /ios/i;
        if (platformReg.test(system.platform)) {
          self.titleBarHeight = 44;
        } else {
          self.titleBarHeight = 48;
        }

        self.navBarHeight = self.statusBarHeight + self.titleBarHeight;
      }
    });
  },


自定义导航栏的可自定义内容：标题文字、文字颜色、标题栏背景色、回退按钮是否显示、home按钮的地址。示例代码如下：


<navigation-bar :title="videoTitle"
  :navBackgroundColor="'pink'"
  :titleColor="'green'"
  :back-visible="true"
  :home-path="'/pages/index/main'"></navigation-bar>
