Not sure what I'm doing wrong here:
var eventDetails = new Event(key);
.factory("Event", ["$FirebaseObject", "$firebase",
function($FirebaseObject, $firebase, settings) {
var EventFactory = $FirebaseObject.$extendFactory({
});
return function(eventId) {
var ref = FIREBASE_REF.child('events/' + eventId);
var sync = $firebase(ref, {
objectFactory: EventFactory
});
return sync.$asObject(); // this will be an instance of UserFactory
}
}
])
eventDetails.$loaded(function(){
eventList.push(eventDetails);
});
Every item in eventList is an object with $id = the same object, rather than $id = some string.

Here is my code I tried,
var array=[];
var list = this.state.list;
var getList = function(i){
var add = +i + 1;
return {
["value"+add]:{
Description:list[i].Description,
Length:list[i].Length,
Height:list[i].Height,
Weight:list[i].Weight,
VolumeWeight:list[i].VolumeWeight,
ActualWeight:list[i].ActualWeight,
}
}
}.bind(this)
for(var i in list){
array.push(getList(i));
}
var dataArray = array.map(function(e){
return JSON.stringify(e);
});
dataString = dataArray.join(",");
data1 = {
ConsigneeBranchName:this.state.searchText,
ConsigneeBranchCode:this.state.code,
ConsigneeBranchFullAddress:this.state.DAddress,
SenderBranchCode:this.state.code1,
SenderBranchName:this.state.searchTexts,
SenderBranchFullAddress:this.state.Address,
CreatedByEmployeeCode:id,
CreatedByEmployeeFullName:userName,
jsonString:{
JsonValues:{
id:"MyID",
values:dataString
}
}
}
But I want the result is exactly this
var result = {
"ConsigneeBranchName":"",
"ConsigneeBranchCode":"",
"ConsigneeBranchFullAddress":"",
"SenderBranchCode":"",
"SenderBranchName":"",
"SenderBranchFullAddress":"",
"CreatedByEmployeeCode":"",

}
}
}
};
Please any one help me
I want the object with dynamic keys within a single object {key1:{des:1,value:as},key2:{des:2,value:aw},key3:{des:3,value:au}}
can you please help me I have tried so many times
see this below image I want this part, inside the single object, I can join multiple objects with dynamic keys
lodash already has a function called keyBy, you can use it to get this functionality. If adding lodash doesn't make sense in your project.
I have implemented a vanilla JS version.
function keyBy(array, mapperFn) {
const resultObj = {};
array.map(item => resultObj[mapperFn(item)] = item);
return resultObj;
}
function arrayToObject (array, keyName = 'id') {
return keyBy(array, function(element) {return element[keyName]});
}
API:
arrayToObject(targetArray, stringNameOfThePorpertyYouWantToUseAsKey);
USAGE:
const listOfUsers = [{name: 'Jenitha', reputation: 6}, {name: 'Chandan', reputation: 3}];
const mapOfUsersByName = arrayToObject(listOfUsers, 'name');
I have created a json file containing my Sql Server datas. With the XmlHttpRequest's GET method, I am reading json file and iterating and saving those records to my IndexedDB.. Everything is working fine.. After the end of the iteration, I wrote a code to alert the user.. But the alert message is displayed very quickly, but when I see it in the console window, the saving operation is till processing.. I want to alert the user, only after the operation is completed..
My code is,
if (window.XMLHttpRequest) {
var sFileText;
var sPath = "IDBFiles/Reservation.json";
//console.log(sPath);
var xhr = new XMLHttpRequest();
xhr.open("GET", sPath, 1);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200) {
if (xhr.responseText != "") {
sFileText = xhr.responseText;
//console.log(sFileText);
var val = JSON.parse(sFileText);
var i = 0;
var value = val.length;
for(var i in val)
{
var code = val[i].RTM_res_category_code;
var desc = val[i].RTM_res_category_edesc;
addReserv(code, desc);
}
if(i >= value-1) {
console.log("Reservation Load Completed... "+i);
document.getElementById("status").innerHTML = "Reservation Loading Success...";
}
}
}
}
xhr.send();
}
//Passing Parameters to Reservation
function addReserv(code, desc)
{
document.querySelector("#status").innerHTML = "Loading Reservation.. Please wait...";
var trans = db.transaction(["Reservation"], "readwrite");
var store = trans.objectStore("Reservation");
//console.log(store);
var reserv={ RTM_res_category_code : code, RTM_res_category_edesc : ''+desc+'' };
var request = store.add(reserv);
request.onerror = function(e) {
console.log(e.target.error.name);
document.querySelector("#status").innerHTML = e.target.error.name;
}
request.onsuccess = function(e) {
console.log("Reservation Saved Successfully.");
//document.querySelector("#status").innerHTML = "Reservation Loaded Successfully.";
}
}
Thanks for the question.
What you are currently doing works, but the alert comes to soon because of the async nature of the IDB.
What you should to avoid this.
1. Create your transaction only once.
2. Do all your operations in this one transaction.
3. The transaction object has an oncomplete callback you can use to notify the user.
Concrete on your example. Instead of looping over the items in the ajax callback, pass the collection to your add method and loop there
if (window.XMLHttpRequest) {
var sFileText;
var sPath = "IDBFiles/Reservation.json";
//console.log(sPath);
var xhr = new XMLHttpRequest();
xhr.open("GET", sPath, 1);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200) {
if (xhr.responseText != "") {
sFileText = xhr.responseText;
//console.log(sFileText);
var val = JSON.parse(sFileText);
import(val);
}
}
}
xhr.send();
}
function import(values)
{
document.querySelector("#status").innerHTML = "Loading Reservation.. Please wait...";
var trans = db.transaction(["Reservation"], "readwrite");
var store = trans.objectStore("Reservation");
var i = 0;
var value = val.length;
for(var i in val)
{
var code = val[i].RTM_res_category_code;
var desc = val[i].RTM_res_category_edesc;
var reserv={ RTM_res_category_code : code, RTM_res_category_edesc : ''+desc+'' };
var request = store.add(reserv);
request.onerror = function(e) {
console.log(e.target.error.name);
document.querySelector("#status").innerHTML = e.target.error.name;
}
request.onsuccess = function(e) {
console.log("Reservation Saved Successfully.");
//document.querySelector("#status").innerHTML = "Reservation Loaded Successfully.";
}
}
trans.oncomplete = function () {
console.log("Reservation Load Completed... "+i);
document.getElementById("status").innerHTML = "Reservation Loading Success...";
}
}
I'm having a bit of a problem getting a deferred returned from a method in a widget. The method is itself returns a Deferred as it's an xhrPost. The code is as such (using dojo 1.8)
Calling Code:
quorum = registry.byId("quorumPanel");
var deferredResponse = quorum.updateSelectionCount();
deferredResponse.then(function(data){
console.log("Success: ", data);
}, function(err){
console.log("Error: ", err);
});
and the code in the widget:
updateSelectionCount: function() {
var self = this;
var deferredResponse = xhr.post({
url: "ajxclwrp.php",
content: [arguments here],
handleAs: "json"});
deferredResponse.then(function(response) {
var anotherDeferred = new Deferred();
var _boolA = true;
var _boolB = true;
dojo.forEach(response.result, function(relationshipInfo){
[do a bunch of stuff here too set _boolA and/or _boolB]
});
self._sethasRequiredAttr(_hasRequired);
self._setHasRequestedAttr(_hasRequested);
self.quorumInfo.innerHTML = quorumHtml;
// Below is not working
anotherDeferred.resolve('foo');
return anotherDeferred;
});
}
Do I need to set up another promise and use promise/all. Im confused/frustrated at this point.
TIA.
the .then() method returns another deferred. You just need to put a return statement in.
updateSelectionCount: function() {
var self = this;
var deferredResponse = xhr.post({
url: "ajxclwrp.php",
content: [arguments here],
handleAs: "json"});
return deferredResponse.then(function(response) {
var _boolA = true;
var _boolB = true;
dojo.forEach(response.result, function(relationshipInfo){
[do a bunch of stuff here too set _boolA and/or _boolB]
});
self._sethasRequiredAttr(_hasRequired);
self._setHasRequestedAttr(_hasRequested);
self.quorumInfo.innerHTML = quorumHtml;
return "foo";
});
}
To start off with, I would like to say that I have been looking on the internet for a really long time and have been unable to find the answer, hence my question here.
My latest school project is to create an admin page for adding articles to a database, the articles are connected to a point on a google map. The requirement for adding the point on the map is that the user is able to click the map once and the marker is produced, if the map is clicked a second time the first marker is moved to the second location. (this is what I am struggling with.)
The problem is, as the code is now, I get the error that markersArray is undefined. If I place the var markersArray = new Array; underneath the eventListener then I get an error that there is something wrong the main.js (googles file) and markersArray[0] is undefined in the second if.
By the way, I have to use google maps API v2, even though it is old.
<script type="text/javascript">
//<![CDATA[
var map;
var markers = new Array;
function load() {
if (GBrowserIsCompatible()) {
this.counter = 0;
this.map = new GMap2(document.getElementById("map"));
this.map.addControl(new GSmallMapControl());
this.map.addControl(new GMapTypeControl());
this.map.setCenter(new GLatLng(57.668911, 15.203247), 7);
GDownloadUrl("genxml.php", function(data) {
var xml = GXml.parse(data);
var Articles = xml.documentElement.getElementsByTagName("article");
for (var i = 0; i < Articles.length; i++) {
var id = Articles[i].getAttribute("id");
var title = Articles[i].getAttribute("title");
var text = Articles[i].getAttribute("text");
var searchWord = Articles[i].getAttribute("searchWord");
var point = new GLatLng(parseFloat(Articles[i].getAttribute("lat")),
parseFloat(Articles[i].getAttribute("lng")));
var article = createMarker(point, id, title, text);
this.map.addOverlay(article);
}
});
}
var myEventListener = GEvent.bind(this.map,"click", this, function(overlay, latlng) {
if (this.counter == 0) {
if (latlng) {
var marker = new GMarker(latlng);
latlng1 = latlng;
this.map.addOverlay(marker);
this.counter++;
markers.push(marker); //This is where I get the error that markersArray is undefined.
}
}
else if (this.counter == 1) {
if (latlng){
alert (markers[0]);
this.map.removeOverlay(markers[0]);
var markers = [];
this.map.addOverlay(marker);
this.counter++;
}
}
});
}
function createMarker(point, id, title, text) {
var article = new GMarker(point);
var html = "<b>" + title + "</b> <br/>"
GEvent.addListener(article, 'click', function() {
window.location = "article.php?id=" + id;
});
return article;
}
I solved the problem. I'm not exactly sure why it worked but this is what it looks like now:
var markersArray = [];
function load() {
if (GBrowserIsCompatible()) {
this.counter = 0;
this.map = new GMap2(document.getElementById("map"));
this.map.addControl(new GSmallMapControl());
this.map.addControl(new GMapTypeControl());
this.map.setCenter(new GLatLng(57.668911, 15.203247), 7);
GDownloadUrl("genxml.php", function(data) {
var xml = GXml.parse(data);
var Articles = xml.documentElement.getElementsByTagName("article");
for (var i = 0; i < Articles.length; i++) {
var id = Articles[i].getAttribute("id");
var title = Articles[i].getAttribute("title");
var text = Articles[i].getAttribute("text");
var searchWord = Articles[i].getAttribute("searchWord");
var type = Articles[i].getAttribute("type");
var point = new GLatLng(parseFloat(Articles[i].getAttribute("lat")),
parseFloat(Articles[i].getAttribute("lng")));
var article = createMarker(point, id, title, text);
this.map.addOverlay(article);
}
});
}
var myEventListener = GEvent.bind(this.map,"click", this, function(overlay, latlng) {
var marker = new GMarker(latlng);
if (this.counter == 0) {
if (latlng) {
latlng1 = latlng;
this.map.addOverlay(marker);
markersArray.push(marker);
this.counter++;
}
}
else if (this.counter == 1) {
if (latlng){
this.map.removeOverlay(markersArray[0]);
this.map.addOverlay(marker);
this.counter++;
}
}
});
}
function createMarker(point, id, title, text) {
var article = new GMarker(point);
var html = "<b>" + title + "</b> <br/>"
GEvent.addListener(article, 'click', function() {
window.location = "article.php?id=" + id;
});
return article;
}
How do you serialize the JsonStore content? I tried Ext.encode(store.data.items), but it throws an exception "too many recursions".
Here's a quick function that should work
function(store) {
if(typeof(store) != 'object') { return ''; }
var dataArray = [];
var encodedData = '';
var data = store.data.items;
Ext.each(data, function(item, index, array) {
dataArray.push(item.data);
});
return Ext.encode(dataArray);
},
Here's another option that uses the each() function on the store itself.
function getEncodedStoreItems(storeName) {
var encodedData = "";
if (typeof storeName !== "undefined") {
var store = Ext.data.StoreManager.lookup(storeName);
if (store != null) {
var data = [];
store.each(function(item, index, count) {
data.push(item.data);
});
encodedData = Ext.encode(data);
}
}
return encodedData;
}
