由 ℡╲_俬逩灬. 提交于 2019-12-11 06:16:45
问题 In the following example, I have a parent custom element calling a child custom element. The child has a variable color CSS property for p elements that can be defined in the parent CSS. In the JS of the child element, I want to read the --custom-color value selected at the parent. In this case, the value is yellow . Put another way: when the getCustomColor() method is run, I want the console log to read "Your custom color is yellow." What JavaScript do I put in the getCustomColor() method to

问题 I am trying to return user data from a login with Polymer. I have it working with Postman, but am having trouble translating it into Polymer.

Polymerfire google auth not working

问题 I'm new to Polymer and Firebase (and as a programmer as well), I'm trying to do a simple login with Google and show the user is logged in. Google Auth is enabled in Firebase. The logout button should be hidden when there is no user logged in, but when I click the login button, nothing happens. There are no warnings in the browser's console. Here is the code that I'm using: <!DOCTYPE html> <html> <head> <link rel="import" href="bower_components/polymerfire/firebase-app.html"> <link rel="import

Polymer: Updating Templatized template when parent changes

由 廉价感情. 提交于 2019-12-11 05:44:13
问题 Following this question, I'm trying to get full two-way binding between parent and template when using Polymer.Templatizer. I'm not sure what the problem is _forwardParentProp and _forwardParentPath are never called when a property changes on parent. I think it's the reason why my templates don't update. Here's my code (also available here). As you can see dom-if binds both ways and the two templates (one created dynamically other declared inside custom element) only update parent but aren't

Polymer app-route query string format

由 柔情痞子 提交于 2019-12-11 05:29:50
问题 I replaced PageJS routing in our application with app-location and app-route , and everything seems to be working except the query parameters. I noticed it can only read URLs like host?param1=val1#/view , not host#view?param1=val1 how PageJS used to. Upon further digging, I discovered that this is actually an RFC standard. I find it odd that PageJS and Angular can use the nonstandard query string format. Is there a way to use the query-params attribute of app-route to read the nonstandard
