How to cover the native navigation bar and status bar with custom pop-ups in Uniapp development

When developing apps and mini-programs using the Uni framework, since the native navigation bar and status bar are rendered by the native framework, their level will be higher than that of all content areas, including the custom pop-up component also cannot achieve the purpose of covering the native navigation bar. After reading the technical information, many developers said that nvue can be used to achieve this effect, but I feel that the implementation process is too complicated and the compatibility is not very good.

So is there any simple way to achieve the effect of covering the native navigation bar? The answer is yes, otherwise I wouldn’t be wasting everyone’s precious time by writing this article, right? Anxious readers can look at the picture first. The picture I gave has already achieved this effect.

First of all, we need to know that setting the level (z-index) value through CSS cannot achieve the purpose. Even if it is set to 1000000 or greater, it will have no effect (except for publishing to H5). This is due to the page rendering logic of the Uni framework.

// 设置多大都无效
.popup { z-index: 1000000 }

Some technologies may do this: change the navigation bar and status bar to customization, instead of using the native method. Doesn’t this solve the hierarchical problem? Yes, that’s right. This is possible. The problem is solved, but we all know during development that the native navigation bar and status bar are incomparable to non-native ones in terms of rendering effect and compatibility with various terminals. In addition, using non-native methods is beyond the scope of this article.

I will introduce a method to you here, and it is very simple. Since we cannot cover the native navigation bar through the pop-up window component, we can make the pop-up window into a page, and then render the page into a pop-up window. Effect, we all know that jumping to a new page can cover the native navigation bar and status bar, but the effect of jumping to a new page is not good, so what we did was to make this page a pop-up window. Let the user not feel that they are jumping to a new page, just like popping up on the current page (such as our common function of receiving coupons on the product details page).

Let’s take the coupon receiving function as an example. For example, the path to the page that displays coupons is: pages/popup/coupon.vue. We configure the following in the pages.json file:

{
  "path": "pages/popup/coupon",
    "style": {
      "navigationStyle": "custom",
      "navigationBarTextStyle": "white",
         "app-plus": {
           "animationType": "fade-in",
           "background": "transparent",
           "backgroundColor": "transparent",
           "popGesture": "none" // 关闭IOS屏幕左边滑动关闭当前页面的功能
        }
    }
}

Then we write the vue file on the coupon collection page that needs to pop up (note the use of open-type="navigate"):

领券

In just the above two steps, the custom pop-up window is completed to cover the native navigation bar and The effect of the status bar, and it is compatible with APPs and mini-programs, will be slightly different on the H5 side, but it is acceptable. If you want better effects, it is recommended to use the method of setting levels introduced above.

Some users have reported that this method is not easy to transfer values ​​interactively. In fact, this is not a problem, and there are solutions. We can use uni.setStorageSync or directly pass parameters on the page.

If you need the uni source code, you can download it from the Dcloud plug-in market, it is completely free: Can cover the pop-up effect of the native navigation bar and status bar
