问题 I have the following template: <iron-ajax id="ajax" url="backend/api.php?operacion=contenidos&idf=[[datos.id]]&len=[[len]]" handle-as="json" verbose=true last-response={{ajaxResponse}} loading="{{cargando}}"> </iron-ajax> <template is="dom-repeat" items="[[ajaxResponse]]"> The AJAX response contains the following JSON (correct): { "1": [{ "id": "6", "idfolleto": "1", "fila": "1", "orden": "1", "tipo": "carrousel", "titulo": "", "subtitulo": null, "color1": null, "color2": null, "color_fondo":

问题 Due to the lack of multi-dimensional array support in dart, I thought of using List. Dart code : class MyModel extends Object with Observable { @observable List<List<int>> dataList = toObservable(new List<List<int>>()); } void main() { initPolymer().run(() { Polymer.onReady.then((_) { var template = querySelector("#bindValueTemplate") as AutoBindingElement; var model = template.model = new MyModel(); for (int i=0; i<2;i++) { List<int> in1 = new List<int>(); for (int j=0; j<2; j++) { in1.add(j

问题 We currently updated a project from Polymer 1 to the Polymer 2/ hybrid version. I know that webcomponents-hi-sd-ce.js is the polyfill for edge. When testing the page on Microsoft Edge I now get an error indicating that webcomponents-hi-sd-ce.js.map could not be found (404). The same error occurs when loading the project with webcomponents-lite.js I couldn't find similar cases so I figured this might be a issue in Polymer 2. I tried importing the script directly by myself but that didn't help

问题 So I just updated my project from Polymer v0.4.2 to v0.5.1 of the Polymer library. One thing that seemed to have changed is how the paper-dialog element is implemented. In v0.4.2, when I had a paper-dialog inside of my custom element, I could customize it with CSS inside of my element using core-style elements. In v0.5.1, if I understand correctly, the paper-dialog is no longer implemented inside my component, but instead it's implemented in the core-overlay-layer element which is in the html

问题 I have a list of time zones that needs to be a reusable component. How do I make my list of time zones a reusable component in Polymer? I need this custom element to provide whether a time zone was selected (isSelected) and a function or property to get the selected time zone name. This is driving me mad! Thanks in advance. Below is a component file called, 'time-zones.html'. I removed all the BS JavaScript I was trying because clearly it wasn't working. The only thing working is the loading

问题 This question had been modified to match the actual problem. The original question mistakingly focused on iron-ajax, please see the original problem below. The question should have been: Please advice why child iron-ajax element is not ready during the 'ready' callback of my-component defined as follows: <dom-module id="my-component"> <template> <link rel="import" href="../../../bower_components/iron-ajax/iron-ajax.html"> <iron-ajax id="selectionLoader" url="" method="GET" handle-as="json"

问题 I'm trying to use paper-date-picker inside my element. How to pass value to paper-date-picker's 'date' attribute? <!-- This is working: --> <paper-date-picker date="2000/1/21"></paper-date-picker> <!-- This is NOT working: Inside <my-birthdate birthdate="1977/1/2"></my-birthdate> --> <paper-date-picker date='{{birthdate}}'></paper-date-picker> Here is the Plunk. 回答1: After looking at the source for the date-picker, it doesn't handle text very well. Basically, you have to add an observer that

问题 I am trying to test a custom Polymer element using their web-component-tester. Many of the examples make use of test-fixture. I would like to test my custom element using databinding, but I'm struggling to get data binding to work. Essentially, I want to take my custom element, assume that the variables are bound, and assert things about it. I'm trying to follow the example in the test-fixture README. Note also that I originally posted this question on their issue tracker before realizing
