页面的onShow函数里调用navigateBack不起作用，求解 - WXOPEN Club

navigateBack

onShow: function() {

let pages = getCurrentPages();

let currentPage = pages[pages.length - 1];

if (currentPage.logout_called) {

console.log('here...');

currentPage.logout_called = undefined;

wx.navigateBack({

});

return;

}

为什么？求解

navigateTo跳转过来的页面才能返回吧
