Hi Im just a rookie with polymer, I hope this question doesnt sound stupid for you :(
I am triying to make a image gallery and I am using this idea: From this page
<dom-module id="simple-gallery" >
<script>
HTMLImports.whenReady(function () {
(function() {
var current_index = 0;
var image_length = 0;
Polymer({
is: "simple-gallery",
ready: function() {
var images = Polymer.dom(this).querySelectorAll('img');
var container = this.$.links;
for (var img in images) {
images[img].addEventListener('click',this.load_popup);
container.appendChild(images[img]);
}
},
load_popup: function(e, detail, sender) {
e.preventDefault();
var links = document.getElementById('links');
image_length = links.getElementsByTagName('img').length;
var image_url = e.target.getAttribute('data-original');
var modalbody = document.getElementsByClassName("modal-body")[0];
var modal_img = modalbody.getElementsByTagName('img')[0];
modal_img.setAttribute("src",image_url);
var modal = document.getElementsByClassName("modal")[0];
modal.style.display = 'block';
current_index = parseInt(e.target.getAttribute('data-index').replace("s",""));
return false;
},
next: function () {
current_index = current_index + 1;
if(current_index == (image_length + 1) ){
current_index = 1;
}
var current_image = document.querySelectorAll("[data-index='s"+current_index+"']");
image_url = current_image[0].getAttribute('data-original');
var modalbody = document.getElementsByClassName("modal-body")[0];
var modal_img = modalbody.getElementsByTagName('img')[0];
modal_img.setAttribute("src",image_url);
},
prev: function () {
current_index = current_index - 1;
if(current_index == 0 ){
current_index = image_length;
}
var current_image = document.querySelectorAll("[data-index='s"+current_index+"']");
image_url = current_image[0].getAttribute('data-original');
var modalbody = document.getElementsByClassName("modal-body")[0];
var modal_img = modalbody.getElementsByTagName('img')[0];
modal_img.setAttribute("src",image_url);
},
close: function () {
var modal = document.getElementsByClassName("modal")[0];
modal.style.display = "none";
},
});
})();
});
</script>
<template>
I realy dont understand why this code works fine if I use it as in the example, but if I create a proyect with: polymer init app-drawer-template and I use this as an element wich is called from one of the views I have an error :(
Uncaught ReferenceError: HTMLImports is not defined(anonymous function) # simple-gallery.html:91
Surely I am not understanding well something but I dont know why, hope somebody has the time to give me a brief explanation :(
thanks a lot for your time.
I had the same issue so I have added following include in my main html:
<script src="bower_components/webcomponentsjs/webcomponents-lite.js"></script>
Which worked for me.
I started to use angular-jsdoc for document my AngularJS code.
I have a service with some methods.
Some of the methods, return an object with another methods:
Here is an example of my service (with simple method and complex method)
angular.module('map').service('pointUtils', function ($http) {
var self = this;
// simple function
self.removeAllPoints = function () {
// remove all points
};
// complex function
self.createPoint = function (params) {
var pointData = {
isVisible :params.isVisible || true,
color : params.color || 'blue'
};
var pointObj = {};
pointObj.setColor = function (color) {
pointData.color = color;
};
pointObj.getColor = function () {
return pointData.color;
};
pointObj.setVisible = function (visible) {
pointData.isVisible = visible;
};
return pointObj
};
});
what is the way to document this complex method?
thanks,

I have different sections in Firebase with normalized data, and I have routines to get the information, but I cannot loop through the returned records to get data. I want to use the keys in the $firebaseArray() to get data from other $firebaseObject().
GetOneTeam() .... {
var DataRef = GetFireBaseObject.DataURL(Node + '/'); // xxx.firebaseio.com/Schedules/
var OneRecordRef = DataRef.child(Key); // Schedule Key - 1
return $firebaseObject(OneRecordRef);
}
...
var Sched = GetOneSchedule('Schedules', 1);
... // For Loop getting data - Put in HomeId
var TeamRec = GetOneTeam('Teams', HomeId);
var Name = TeamRec.TeamName; // Does not TeamName value from Schedule/1
The following is more of the actual code in case the snippet above is not clear enough. Sample common routine for getting data:
angular.module('MyApp')
.constant('FIREBASE_URL', 'https://xxxxxxxx.firebaseio.com/');
angular.module('MyApp')
.factory('GetFireBaseObject', function(FIREBASE_URL) {
return {
BaseURL: function() {
return new Firebase(FIREBASE_URL);
},
DataURL: function(Node) {
return new Firebase(FIREBASE_URL + Node);
}
};
}
);
// Common code for getting Array/Object from Firebase.
angular.module('MyApp')
.factory("FireBaseData", ["$firebaseArray", "$firebaseObject", "GetFireBaseObject",
function($firebaseArray, $firebaseObject, GetFireBaseObject) {
return {
AllRecords: function(Node) {
var DataRef = GetFireBaseObject.DataURL(Node + '/');
return $firebaseArray(DataRef);
},
OneRecordAllChildren: function(Node, Key) {
var DataRef = GetFireBaseObject.DataURL(Node + '/');
var ParentRecordRef = DataRef.child(Key);
return $firebaseArray(ParentRecordRef);
},
OneRecord: function(Node, Key) {
var DataRef = GetFireBaseObject.DataURL(Node + '/');
var OneRecordRef = DataRef.child(Key);
return $firebaseObject(OneRecordRef);
},
AddRecord: function(Node, Record) {
var DataRef = GetFireBaseObject.DataURL(Node + '/');
var AddRecordRef = DataRef.child(Record.Key);
AddRecordRef.update(Record);
return $firebaseObject(AddRecordRef); // Return Reference to added Record
},
DeleteRecord: function(Node, Key) {
var DataRef = GetFireBaseObject.DataURL(Node + '/');
var DeleteRecordRef = DataRef.child(Key);
DeleteRecordRef.remove();
}
};
}
]);
Individual Controller's retrieval of records from firebase.io:
angular.module('MyApp').service("ScheduleData", ["FireBaseData",
function(FireBaseData) {
var DataPath = 'Schedules';
this.AllSchedules = function() {
return FireBaseData.AllRecords(DataPath);
};
this.AddSchedule = function(GameInfo) {
return FireBaseData.AddRecord(DataPath, GameInfo);
};
this.DeleteSchedule = function(GameKey) {
FireBaseData.DeleteRecord(DataPath, GameKey);
};
this.GetOneSchedule = function(GameKey) {
return FireBaseData.OneRecord(DataPath, GameKey);
};
}
]);
// Structure of a record, including named fields to come from another object (Team/Venue using the OneRecord FireBaseData call to get a $firebaseObject
angular.module('MyApp').factory("ScheduleRecord", function() {
return {
Clear: function(GameInfo) {
GameInfo.Key = "";
GameInfo.HomeTeamId = "";
GameInfo.HomeTeamName = "";
GameInfo.AwayTeamId = "";
GameInfo.AwayTeamName = "";
GameInfo.VenueId = "";
GameInfo.VenueName = "";
GameInfo.GameDate = "";
GameInfo.GameTime = "";
}
};
}
);
Controller module start:
angular.module('MyApp').controller('ScheduleCtrl', ["$scope", "ScheduleData", "ScheduleRecord", "TeamData", "VenueData",
function ($scope, ScheduleData, ScheduleRecord, TeamData, VenueData) {
var ClearEditData = function() {
$scope.ScheduleEditMode = false;
ScheduleRecord.Clear($scope.schedule);
};
var GameSchedules = ScheduleData.AllSchedules();
This next piece is where my question lies. Once the promise returns the static schedule list, I want to loop through each record and translate the Team Id (Home/Away) and Venue Id to the names.
GameSchedules.$loaded().then(function() {
angular.forEach(GameSchedules, function(GameInfo) {
var HomeTeam = TeamData.GetOneTeam(GameInfo.HomeTeamId);
GameInfo.HomeTeamName = HomeTeam.Name;
The GetOneTeam returns a $firebaseObject, based on the HomeTeamId child record. This returns null all the time.
This is the TeamData.GetOneTeam return using the FireBaseData as well.
angular.module('MyApp').service("TeamData", ["FireBaseData",
function(FireBaseData) {
var DataPath = 'Teams';
this.AllTeams = function() {
return FireBaseData.AllRecords(DataPath);
};
this.AddTeam = function(TeamInfo) {
return FireBaseData.AddRecord(DataPath, TeamInfo);
};
this.DeleteTeam = function(TeamKey) {
FireBaseData.DeleteRecord(DataPath, TeamKey);
};
this.GetOneTeam = function(TeamKey) {
return FireBaseData.OneRecord(DataPath, TeamKey);
};
}
]);
As I have a Firebase Object, how can I get my named data objects from the $firebaseObject?
This is a mess. Use $firebaseArray for collections, not $firebaseObject. Most of these strange wrapper factories are unnecessary. AngularFire services already have methods for add, remove, and so on, and all these factories attempt to make AngularFire into a CRUD model and don't actually provide any additional functionality or enhancements.
app.factory('Ref', function(FIREBASE_URL) {
return new Firebase(FIREBASE_URL);
});
app.factory('Schedules', function($firebaseArray, Ref) {
return $firebaseArray(Ref.child('Schedules'));
});
// or if you want to pass in the path to the data...
//app.factory('Schedules', function($firebaseArray, Ref) {
// return function(pathToData) {
// return $firebaseArray(Ref.child(pathToData));
// };
//});
app.factory('Schedule', function($firebaseObject, Ref) {
return function(scheduleId) {
return $firebaseObject(Ref.child('Schedules').child(scheduleId));
}
});
app.controller('...', function(Schedules, Schedule, Ref) {
$scope.newSchedule(data) {
Schedules.$add(data);
};
$scope.removeSchedule(key) {
Schedules.$remove(key);
};
$scope.updateSchedule(key, newWidgetValue) {
var rec = Schedules.$getRecord(key);
rec.widgetValue = newWidgetValue;
Schedules.$save(rec);
};
// get one schedule
var sched = Schedule(key);
sched.$loaded(function() {
sched.widgetValue = 123;
sched.$save();
});
});
In my Service i have the vars i want to display and the getters for it:
var docsLoaded = 0;
var docsToLoad = null;
pouchService.getDocsLoaded = function () {
return docsLoaded;
};
pouchService.getDocsToLoad = function () {
return docsToLoad;
};
While the service is syncing, i want to count the synced docs
pouchService.syncNow = function () {
var foundLastSeq = false;
docsLoaded = 0;
docsToLoad = null;
remoteDB.info().then(function (remoteInfo) {
function findOutDiff(localPosition) {
docsToLoad = (remoteInfo.update_seq - localPosition) + 1;
console.log("docs to load: " + docsToLoad);
}
// start Sync progress
sync = localDB.sync(remoteDB, {live: false})
.on('change', function (info) {
console.log('AI change: ');
console.log(info);
if (info.direction === 'pull') {
if (foundLastSeq === false) {
foundLastSeq = true;
findOutDiff(info.change.last_seq);
}
}
console.log(docsLoaded + " from " + docsToLoad);
docsLoaded++;
})
In my HTML i want to display the progress like this:
{{pouchService.getDocsLoaded()}} from {{pouchService.getDocsToLoad()}}
Now i get sometimes a value from getDocsLoaded, but mostly its zero. When I cancel the Syncprogress i get the value where it's stopped.
So i get the value before it really starts and when it's over, but i want it during the sync progress. (on the console my my progressinfos are working as expected)
Any ideas?
The problem is in applying scope. Jim wrote a nice article about this problem:
jimhoskins.com/2012/12/17/angularjs-and-apply.html
Solved it:
$rootScope.$apply(function () {
docsLoaded++;
});
I have the following scope function in my controller
$scope.getStaff = function (request, response) {
var a = [];
if ($scope.staff !== null) {
// all terms must be contained
a = $scope.staff;
var terms = request.term.toLowerCase().split(' ');
for (var i = 0; i < terms.length; i++) {
var t = terms[i];
if (t) {
a = $.grep(a, function (item, index) {
var v = item.label.toLowerCase();
return v.indexOf(t) !== -1;
});
}
}
}
response(a.length > 0 ? a : null);
};
I'm attempting to test it using jasmine like this:
describe('getStaff', function() {
it('...', function() {
$scope.staff = [
{ label: "test1" },
{ label: "test2" }
];
var req = { term: "a b c" };
expect(req.term.toLowerCase()).toBe('a b c');
var res = function(a) {
return a;
}
var result = $scope.getStaff(req, res).response;
expect(result).toBe(null);
});
});
I'm ultimately trying to see what "a" is in the getStaff function. How can I get that value in my jasmine test?
My answer is really an opinion. Unless you are willing to expose your 'a' in the scope of the controller, then my answer would be "you don't care" your jasmine test should only be testing the answer of response(a.length > 0 ? a : null); returned.
My gut tells me you may want to consider creating a helper function for this code
$.grep(a, function (item, index) {
var v = item.label.toLowerCase();
return v.indexOf(t) !== -1;
});
and unit testing that separate from your getStaff function.
