Navigation

Navigation是小程序的顶部导航组件，当页面配置navigationStyle设置为custom的时候可以使用此组件替代原生导航栏。

示例代码：

{
    "usingComponents": {
        "mp-navigation-bar": "../components/navigation-bar/navigation-bar"
    },
    "navigationStyle": "custom",
    "navigationBarTitleText": "UI组件库"
}

<mp-navigation-bar loading="{{loading}}" show="{{show}}" animated="{{animated}}" color="{{color}}" background="{{background}}" title="UI组件库" back="{{true}}"></mp-navigation-bar>
<view class="page">
    <view class="page__hd">
        <view class="page__title">Navigation</view>
        <view class="page__desc">小程序自定义导航栏</view>
    </view>
    <view class="page__bd page__bd_spacing">
        <button class="weui-btn" type="primary" bindtap="toggleLoading">触发loading</button>
        <button class="weui-btn" type="primary" bindtap="changeColor">修改文字颜色</button>
        <button class="weui-btn" type="primary" bindtap="changeBgColor">修改背景颜色</button>
        <button class="weui-btn" type="primary" bindtap="toggleShow">显示 / 隐藏</button>
        <button class="weui-btn" type="primary" bindtap="toggleAnimated">设置显示 / 隐藏opacity动画</button>
    </view>
</view>

Page({
  data: {
    loading: false,
    color: "#000",
    background: "#f8f8f8",
    show: true,
    animated: false
  },
  toggleLoading() {
    this.setData({
