The editor shows you the operation process through an actual case. The method of operation is simple and fast, and it is practical. I hope that this "WeChat Mini Programs how to achieve page opening limit" article can help you solve the problem.

Preface

As we all know, whether in Mini Program or APP, opening a page is actually creating a new View object, layer by layer. When you click the back button on the page, you close the current page.

One problem involved in this process is the number of open pages. In some designs, such as a product details page, other items will be recommended, and these items will be clicked into the details page. There are recommendations on the details page, and you can click in. In this way, more and more pages will be opened over and over again.

If there is no limit, it will definitely get stuck when the number of openings reaches a certain level. You can't open more than 10 pages in WeChat Mini Programs. After reaching 10 pages, you can't open new pages.

Before this problem, I thought it was Bug, whether it was stuck or not, but later I found that as long as I went back to a page, I could reopen it. The limit of up to 10 pages was discovered.

Specially investigated the Mini Program of other companies and found that there is indeed this problem. I made a hint here to tell the user not to open so many pages, otherwise the user will look at a loss and will not be able to light it.

Each page needs to load data interactively with the background, and I judge it in a unified Http request.

Instance code

Var pages = getCurrentPages (); console.log ("pages:" + pages.length); if (pages.length = = 10) {wx.showToast ({title: "too many pages open, please go back and close a few pages", icon: 'none', duration: 2000}) setTimeout (() = > {wx.navigateBack ({})}, 2000) return;}

When you open the 10th page, give a prompt, and then jump back to the previous page.
