How to prohibit return when uniapp jumps successfully

With the continuous development of mobile Internet, the demand for mobile applications is also increasing. In these applications, in order to improve the user experience, many developers will use the jump function to help users quickly enter different pages of the application. In uniapp, the jump function is also widely used. However, sometimes we want to prevent users from returning to the previous page after successfully jumping to the target page. So, how to implement this function?

Uniapp is a cross-platform application development framework based on Vue.js. It allows developers to build applications that can run on multiple platforms through one source code. Therefore, the method of implementing the disable return function in uniapp may be different compared to a native mobile application. Below, we briefly introduce the method of implementing the prohibition of return function in uniapp.

1. Use the uni.navigateBack method

In uniapp, we can use the uni.navigateBack method to implement the function of prohibiting return. This method is an API that jumps to a certain page. When the jump is successful, we can control whether we can return to the previous page by passing in a delta parameter. The delta parameter represents the number of pages returned. For example, a delta of 1 means returning to the previous page, a delta of 2 means returning to the previous two pages, and so on. When we set the delta parameter to 0, we can implement the function of prohibiting return.

Next, we can combine a sample code to understand more clearly how to use this method.

// 在page1中跳转到page2，并禁止返回
uni.navigateTo({
  url: '/pages/page2/page2',
  success() {
    // 跳转成功后，设置delta为0
    uni.navigateBack({
      delta: 0
    });
  }
});

In the above code, we use the uni.navigateTo method to jump to the page2 page, and after the successful jump, we call the uni.navigateBack method to set the delta parameter to 0. In this way, when the user is on page 2 and clicks the return button, he will not be able to return to page 1.

2. Use the uni.reLaunch method

In addition to using the uni.navigateBack method, we can also use the uni.reLaunch method to implement the function of prohibiting return. Compared with the uni.navigateBack method, the uni.reLaunch method is to restart the application and jump to a certain page. Therefore, we can pass the main interface of the application as a parameter to this method, replacing the previous page.

Next, let’s take a look at the sample code using the uni.reLaunch method:

// 在page1中跳转到page2，并禁止返回
uni.navigateTo({
  url: '/pages/page2/page2',
  success() {
    // 跳转成功后，使用reLaunch方法跳转到主界面
    uni.reLaunch({
      url: '/pages/index/index'
    });
  }
});

In the above code, we use the uni.reLaunch method to jump after successfully jumping to the page2 page Go to the main interface of the application. Since this method restarts the application, the previous page will not be retained. In this way, we can also implement the function of prohibiting return.

3. Summary

In uniapp, we can implement the function of prohibiting return by using the uni.navigateBack and uni.reLaunch methods. Both methods have their own advantages and disadvantages, and we can choose which one to use based on the specific situation. For some users who are more familiar with page switching, the function of disabling return may reduce their experience. Therefore, when using this function, you need to consider the user's usage habits and experience. I hope the introduction in this article can help everyone.
