Vue Onsen Android back button

[Adi Abdullah]

Hi, I’m trying to make my app get to the previous page using the android button and not the v-ons-back-button but it doesn’t seem to work. Is there something I missed out on?

Currently I got a message saying ‘Uncaught ReferenceError: Symbol is not defined’ in the console when pressing the back button on my phone.

I’m using :

• onsenui@2.2.5
• vue@2.3.0
• vue-onsenui@2.0.0-beta.3

@Adi-Abdullah Hi! Thanks for reporting. I’ll try to have a look at it tomorrow. I haven’t tried vue@2.3.0 yet, not sure if it is related to that.

@Fran-Diox
I found that this error occurred because:

• We are using for-of syntax in util._captureTree (link).
• for-of syntax is transpiled by Babel.
• But babel-plugin-transform-es2015-for-of outputs code with Symbol (link)
  • Symbol is a feature of ES2015, so this might be a bug
• Symbol is supported since Android 5.1 WebView (link).

What we could do is (1) polyfill Symbol or (2) fix babel-plugin-transform-es2015-for-of.

@asial-matagawa Oh, thanks for checking! I saw that the latest Vue release mentioned something related to Symbol and thought that it might affect.
Maybe we can simply remove for of, I don’t really mind :)

@Fran-Diox Are there any temporary solution for this? Or I can expect a patch up for this soon? :confused: Plus do I need to create an issue for this ? I’m quite new so bear with me on this haha

[Fran Diox]

@Adi-Abdullah It’s already fixed so no need to open an issue. I think we will release onsenui@2.2.6 either today or tomorrow. Otherwise, you can download the latest development version from this link :)
