Hi, I have use monaca.pushPage(subcategory.html, .....) and no error but can't move to subcategory.html page.

Any help appreciated.

Answer 1

ons variable does not store the navigators anymore. You must use var attribute in the navigator and give it a name to call it afterwards. For example:

<ons-navigator var="myNavigator">
    ...
</ons-navigator>

And then use it with myNavigator.pushPage(...). More info here: http://onsen.io/reference/ons-navigator.html

Hope it helps!
