How to jump from random page to specified page in uniapp

In recent years, with the popularity of mobile applications and the continuous innovation of development tools, more and more developers are turning to cross-platform development. As a front-end framework for developing cross-platform applications, Uniapp has the characteristics of multi-terminal support and ease of use, but it also encounters some problems. One of them is the implementation of jumping from a random page to a specified page.

Below, we will introduce in detail how to jump from a random page to a specified page in Uniapp.

First, we need to understand some basic concepts. In Uniapp, every page except the homepage can be used as an entrance page. To jump from one page to another, we need to use the built-in uni.navigateTo() method. This method can jump to the page based on the incoming path and add the path to the routing stack, so that we can return to the previous page through the uni.navigateBack() method.

Next, we need to determine how to jump from a random page to a specified page. First, we need to plan all pages and store their paths. This can be achieved by configuring page routing in the app.json file.

For example, we can add the following code to the app.json file:

"pages": [
    {
      "path": "pages/home/home",
      "name": "home"
    },
    {
      "path": "pages/about/about",
      "name": "about"
    },
    {
      "path": "pages/contact/contact",
      "name": "contact"
    }
  ]

Here, we have added three pages, namely home, about and contact, and specified their path.

Next, we can use the uni.navigateTo() method to jump from a random page to a specified page. The specific implementation code is as follows:

  //获取所有页面的路由路径
  const pages = getCurrentPages();
  const routes = pages.map((page) => page.route);
  //随机选取一个页面
  const randomPageRoute = routes[Math.floor(Math.random() * routes.length)];
  //跳转到随机选取的页面
  uni.navigateTo({
    url: '/' + randomPageRoute,
  });

In this code, we first obtain the routing paths of all current pages, and then randomly select a page to jump.

Finally, we need to add an event that triggers the jump to the page. This can be achieved by adding a click event to the button. The specific code is as follows:

<template>
  <view>
    <button @click="navigateToRandomPage">跳转到随机页面</button>
  </view>
</template>
<script>
  export default {
    methods: {
      navigateToRandomPage() {
        //调用跳转的方法
      }
    }
  }
</script>

At this point, we have successfully implemented the function of jumping from a random page to a specified page.

To sum up, to jump from a random page to a specified page, we need to determine the paths of all pages, use the built-in uni.navigateTo() method to jump, and add a trigger jump to the page turn event. Hope this article can help Uniapp developers.
