getCurrentPages() is uesed to get the instance of the page stack, it will return an array of page. The first element is the home page, and the last element is the current page.

The framework maintains the current pages by stack. And the relationship of routing switch and page stack is shown in the following table.

Routing	Page Stack Behavior
Initialization	Push new page into stack
Open a new page	Push new page into stack
Redirect of page	Pop current page from stack and push new page into stack
Page returned	Pop current page from stack
Tab switch	Pop all pages from stack except the new tab page

Following codes can help to detect whether current stack reaches 5 layer of pages.

copy

if (getCurrentPages().length === 5) {
    my.redirectTo({
        url: '/pages/logs/logs'
    });
} else {
    my.navigateTo({
        url: '/pages/index/index'
    });
}

Note: do not try to modify the page stack, or error about page routing and page status may happen.
