Question

我一直收到这个错误，我正在使用故事板，并希望在我更改场景时删除网页

contact.lua:99: ERROR: table expected. If this is a function call, you might have used '.' instead of ':'
stack traceback:
    [C]: ?
    [C]: in function 'insert'

何时使用此代码

local myMap = native.showWebPopup(450, 260, 460, 340 , "http://google.com", options )
print("done")
group:insert(myMap)

无论如何我可以分组吗？编辑：这是我正在使用弹出窗口的页面，我希望能够在我更改页面时删除弹出窗口

注意：Native Web Popup对象与其他本机对象一样，不能在组中工作，并且始终显示在常规显示对象（矢量，图像和文本）之上。

Answer 2

使用cancelwebpoup修复代码。这将删除屏幕上的所有webpopup bool的原因和if语句出于某种原因故事板在输入后存在一个场景，删除了网络弹出窗口，无论如何这是现在的解决方法，直到可以做出更好的事情

    function scene:enterScene( event )
    local group = self.view
     native.showWebPopup(450, 260, 460, 340 , "http://google.com", options )
    poup=false
    -- do nothing

end

-- Called when scene is about to move offscreen:
function scene:exitScene( event )
    local group = self.view
    if popup==true then
     native.cancelWebPopup()
     popup=false
     else 
     popup=true
     end

    -- INSERT code here (e.g. stop timers, remove listenets, unload sounds, etc.)

end

我似乎无法将native.showpopup corona lua分组
