polymer-1.0

I'm using Polymer 1.0 and when there is a click on a button in Chrome a MouseEvent is generated. This MouseEvent object has a path property which is an ordered array of parent elements to the clicked button. In Firefox & Safari, however, a click is generated which does not have a path property.

I saw another question and answer that uses fallback-selection , here , but I want to force the user to choose "yes" or "no". <paper-radio-group selected="" attr-for-selected="value" data-required="{{question.required}}"> <paper-radio-button name="{{question.id}}" value="yes">Yes</paper-radio-button> <paper-radio-button name="{{question.id}}" value="no">No</paper-radio-button> </paper-radio-group> The only way I can think of, is to run a checker function at the end to check for it specifically. checkAnswers: function() { var

Is Polymer v1.0 compatible with phonegap build? I tried to build the polymer starter kit but the build was not a success. @Ahemed, Polymer is new and experimental. It works with only a few browsers. Phonegap, at this time, does NOT support polymer. Your questions are best directed to the one and only (as of the moment) meetup group in Silicon Valley on this subject. http://www.meetup.com/Web-Components-Silicon-Valley-Meetup/ Best of Luck. 来源： https://stackoverflow.com/questions/31636632/is-polymer-v1-0-compatible-with-phonegap-build
