Javascript callback function executed 2 times

users can sign in to my system using google sign in so when use pressing google sign in button his account will be create in mysql database
my problem is every users account created two time when user trying to sign in by google
in other words function of create account executed two time for every user
here is my html code
<a id="gp_login" href="javascript:void(0)" onclick="javascript:googleAuth()">Login using Google</a>
this is javascript code
function gPOnLoad(){
// G+ api loaded
document.getElementById('gp_login').style.display = 'block';
}
function googleAuth() {
gapi.auth.signIn({
callback: 'gPSignInCallback',
clientid: '636950137786-j3siaftgshtf9iamovisf603pplv7jf1.apps.googleusercontent.com',

scope: "https://www.googleapis.com/auth/plus.login email https://www.googleapis.com/auth/user.phonenumbers.read https://www.googleapis.com/auth/user.birthday.read"
})
}
function gPSignInCallback(e) {
if (e["status"]["signed_in"]) {
gapi.client.load("plus", "v1", function() {
if (e["access_token"]) {
getProfile()
} else if (e["error"]) {alert(e['error'])
console.log("There was an error: " + e["error"])
}
})
} else {alert(e["error"]);
console.log("Sign-in state: " + e["error"])
}
}
function getProfile() {
//var e = googleData.getBasicProfile();
var e = gapi.client.plus.people.get({
userId: "me"
});
e.execute(function(e) {
if (e.error) {alert(e.message)
console.log(e.message);
return
} else if (e.id) {var msgs=JSON.stringify(e);
alert(e.displayName);
update_user_data(e);
// save profile data
}
})
}(function() {
var e = document.createElement("script");
e.type = "text/javascript";
e.async = true;
e.src = "https://apis.google.com/js/client:platform.js?onload=gPOnLoad";
var t = document.getElementsByTagName("script")[0];
t.parentNode.insertBefore(e, t)
})()
function update_user_data(response)
{
// var dataString = JSON.stringify(response);
var email=response.emails[0]['value'];
var displayName=response.displayName;
//ar
$.ajax({
type: "POST",
data: {email:email,displayName:displayName},
url: 'Save.php?id=check_user',
success: function(msg) {
var array = msg.split(',');
var email =array[0];alert(email);
var password = array[1];alert(password);
$('#username').val(email);$('#password').val(password);
document.getElementById("modal4c").click();
},
error: function(XMLHttpRequest,textStatus,errorThrown) {//alert(JSON.stringify(msg));
}
});
}
update_user_data() function is to insert account into mysql database but this function is called twice per user.

Not sure why you function runs twice but,
one way to ensure a function runs only once would be make some global flag like this
runOnce = false;
function gPSignInCallback(e) {
if(runOnce) return;
runOnce = true;
// ... rest of the function
}
If you want to avoid global vars you could return a closure like this
function update_user_data(e){
var runOnce = false
return function(){
if(runOnce) return;
runOnce = true;
// ... rest of the function
}
}
And call it like this update_user_data()(e)

Twilio chat events memberUpdated, and userInfoUpdated never fired

i'm looking on what cases are these events is firing, i have implement it on these code
jQuery(document).ready(function() {
var chatChannel;
var chatClient;
var username;
var $input = $('#chat-input');
$.post("/tokens", function(data) {
username = data.username;
chatClient = new Twilio.Chat.Client(data.token);
chatClient.getSubscribedChannels().then(createOrJoinGeneralChannel);
});
function createOrJoinGeneralChannel() {
// Get the general chat channel, which is where all the messages are
// sent in this simple application
// print('Attempting to join "general" chat channel...');
var promise = chatClient.getChannelByUniqueName("#{params[:chat_channel]}");
promise.then(function(channel) {
chatChannel = channel;
console.log("#{params[:chat_channel]} is exist");
console.log(chatChannel);
setupChannel();
return channel.getMembers();
// $input.removeClass('.hidden')
})
.then(function(members){
members.forEach(function(member){
console.log('member', member);
member.on('userInfoUpdated', function(){
console.log('userInfoUpdated', member);
})
})
})
.catch(function() {
// If it doesn't exist, let's create it
console.log("creating #{params[:chat_channel]} channel");
chatClient.createChannel({
uniqueName: "#{params[:chat_channel]}",
friendlyName: 'General Chat Channel'
}).then(function(channel) {
console.log("Created #{params[:chat_channel]} channel:");
console.log(channel);
chatChannel = channel;
setupChannel();
});
});
}
function setupChannel() {
chatChannel.join().then(function(channel) {
printMessage(username + ' joined the chat.');
chatChannel.on('typingStarted', showTypingStarted);
chatChannel.on('typingEnded', hideTypingStarted);
chatChannel.on('memberJoined', notifyMemberJoined);
chatChannel.on('memberLeft', notifyMemberLeft);
chatChannel.on('memberUpdated', updateMemberMessageReadStatus);
});
chatChannel.on('messageAdded', function(message) {
printMessage(message.author + ": " + message.body);
});
}
function updateMemberMessageReadStatus(member){
console.log('memberUpdated');
console.log('member.lastConsumedMessageIndex', member.lastConsumedMessageIndex);
console.log('member.lastConsumptionTimestamp', member.lastConsumptionTimestamp);
}
function leaveCurrentChannel() {
if (chatChannel) {
chatChannel.leave().then(function (leftChannel) {
console.log('left ' + leftChannel.friendlyName);
leftChannel.removeListener('messageAdded', function(message) {
printMessage(message.author + ": " + message.body);
});
leftChannel.removeListener('typingStarted', showTypingStarted);
leftChannel.removeListener('typingEnded', hideTypingStarted);
leftChannel.removeListener('memberJoined', notifyMemberJoined);
leftChannel.removeListener('memberLeft', notifyMemberLeft);
leftChannel.removeListener('memberUpdated', updateMemberMessageReadStatus);
});
}
}
function showTypingStarted(member) {
console.log('somebody is typing');
$('#is_typing').html(member.identity + ' is typing...');
}
function hideTypingStarted(member) {
$('#is_typing').html('');
}
function notifyMemberJoined(member) {
console.log('notifyMemberJoined');
printMessage(member.identity + ' joined the channel');
}
function notifyMemberLeft(member) {
console.log('notifyMemberLeft');
printMessage(member.identity + ' left the channel');
}
$input.on('keydown', function(e) {
if (e.keyCode == 13) {
chatChannel.sendMessage($input.val());
$input.val('');
} else {
//console.log('typing');
chatChannel.typing();
}
});
window.addEventListener("beforeunload", function (e) {
// var confirmationMessage = "\o/";
(e || window.event).returnValue = leaveCurrentChannel(); //Gecko + IE
return leaveCurrentChannel(); //Webkit, Safari, Chrome
});
});
and i've take alook to the console to see if my
console.log('userInfoUpdated', member);
or these guys
console.log('memberUpdated');
console.log('member.lastConsumedMessageIndex', member.lastConsumedMessageIndex);
console.log('member.lastConsumptionTimestamp', member.lastConsumptionTimestamp);
and they are never fired, during my test on the chat events, and i'm confused on how exactly i'm going to display how my users online or the status of a message is read or unread
so please enlighten me on the case, thank you

Twilio developer evangelist here.
According to the JS docs for the latest version of Twilio Chat, the event you need to listen for on members is just called 'updated'. So, listening for 'userInfoUpdated' won't work.
I would also recommend that within this code:
chatChannel.join().then(function(channel) {
//...
chatChannel.on('memberUpdated', updateMemberMessageReadStatus);
//...
})
you use the channel passed to the callback, rather than the original chatChannel object. Like this:
chatChannel.join().then(function(channel) {
//...
channel.on('memberUpdated', updateMemberMessageReadStatus);
//...
})
I don't know if this will fix the issue, but I can't think of anything else right now.

Angularjs how to preserve url in function?

Hi I am developing one Angularjs application. I have three cascading drop downs. Based on the selected values in drop down i am binding div with data received from api(div with ng-repeat). I have implemented paging.
On page load i am binding first dropdown.
var arrMakes = new Array();
$http.get(url + 'api' + '/Vehicle/' + 'GetVehicleMake').success(function (data) {
$.map(data.data, function (item) {
arrMakes.push(item);
});
$scope.list = arrMakes;
var dynamicUrl = url + 'api' + '/Vehicle/' + 'Getcars/';
//bind data to Div randomly.
getcadetails(dynamicUrl);
}).error(function (status) {
});
function getcadetails(baseurl)
{
var arrallcarDetails = new Array();
$http.get(baseurl,{ params: $scope.pagingInfo }).success(function (data) {
$.map(data.data, function (item) {
arrallcarDetails.push(item);
});
$scope.carDetails = arrallcarDetails;
$scope.pagingInfo.totalItems = data.totalcount;
}).error(function (status) {
});
}
getcadetails is a function i am calling from different scenarios. For example,
ng-change event of first dropdown
$scope.getModel = function (selectedMake) {
var selectedMakeData = selectedMake.ID;
var arrModel = new Array();
$http.get(url + 'api' + '/Vehicle/' + selectedMakeData + '/GetVehicleModel').success(function (data) {
$.map(data.data, function (item) {
arrModel.push(item);
});
$scope.Modellist = arrModel;
var dynamicUrl = url + 'api' + '/Vehicle/' + 'Getcars/' + '?MakeID=' + selectedMakeData;
//bind data to Div randomly.
getcadetails(dynamicUrl);
}).error(function (status) {
});
}
In paging i have below function. This is executed when i click on page numbers for example 1,2, etc
$scope.pageChanged = function (currentPage) {
$scope.pagingInfo.pageNumber = currentPage;
getcardetails();
};
Here my problem starts. If i click on any page number $scope.pageChanged function executes. I will get page number to send it to server. after that i will call getcadetails(?). Now how can i get baseurl for getcadetails? Is there any way i can implement this in better way? Any help would be appreciated. Thank you.

i think u can define a variate for selectedMakeData, and define a function to create url. every time before invoke getcardetails() u should calculate the dynamicUrl.
code looks this:
var selectedMakeData = 0;
selection.addEventListener('change', () => {
selectedMakeData = newData;
});
$scope.pageChanged = function (currentPage) {
var url = getUrl();
$scope.pagingInfo.pageNumber = currentPage;
getcardetails(url);
};
function getUrl() {
// return url baseed on selectedMakeData
}

AngularJs two way data binding doesn't work when add SignalR lib

My problem started when I tried to add a library SignalR in my AngularJs project. I do not know why but the data flow has stopped working properly, I mean that when I try to insert an object into an array I do not see it, but when I try to add another one I see first object, and when I try to add a third object I see only the second.
edit : all code in the angular controller.
app.controller('HomeCtrl', ['$scope', 'HttpSrv', '$state', function ($scope, HttpSrv, $state) {
$scope.messages = [];
activate();
function activate() {
if (HttpSrv.CheckToken()) {
loadPage();
}
};
$scope.$on("$destroy", function () {
con.stop();
});
function connectToChat() {
HttpSrv.http('GET', 'home/GetChatToken').then(function (res) {
localStorage.setItem('ChatToken', res.Result);
con.start({ jsonp: true }, function () { console.log('Start'); });
});
}
var con = $.hubConnection("http://localhost:4704/");
var hub = con.createHubProxy('ChatHub');
hub.on('fail', function (res) {
console.error(res);
});
hub.on('addMessage', addMessage);
$scope.trySend = function () {
hub.invoke('SendMessage', localStorage.getItem('ChatToken'), document.getElementById('messageBox').value);
};
function addMessage(name, message, elementId) {
var tempMessage = '<li id="' + elementId + '" class="right clearfix"><div class="chat-body clearfix">'
tempMessage += '<div class="header"><strong class="pull-left primary-font">' + name + ': </strong> <br />'
tempMessage += '</div><p>' + message + '</p></div></li>'
document.getElementById('chatBody').innerHTML += tempMessage;
document.getElementById('messageBox').value = '';
document.getElementById(elementId).scrollIntoView();
document.getElementById('chatBody').focus();
}
function loadPage() {
HttpSrv.http('GET', 'home/get').then(function (res) {
//console.log(res);
if (res.Status == 200 && res.Succeeded) {
connectToChat();
for (var i = 0; i < res.ListResult.length; i++) {
res.ListResult[i].CreateDate = res.ListResult[i].CreateDate.replace('T', ' ').slice(0, 19);
}
$scope.newsList = res.ListResult;
}
});
};}]);
(i use document.getElementById because of the problem)

First, you shouldn't be building markup in your code. Simply add the message to the list and use ng-repeat in your markup.
However, you also must make sure you use $scope.$apply() or $scope.$digest() when you are processing messages from signalR.
function addMessage(name, message, elementId) {
$scope.$apply(function(){
$scope.messages.push(message);
});
}

SharePoint Workflow Subscription Service failed

I have one requirement to start the SP workflow through JavaScript. For this, i have wrote some lines of code to start the workflow.But I am getting a Subscription failed error due to undefined object. This is occuring at ExcecuteasyncQuery method. So i didn't get which object returns the undefined value. My code is shown below.
<script type="text/javascript" src="/_layouts/15/sp.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.core.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.runtime.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.workflowservices.js"> </script>
<script type="text/javascript">
var subID = "3debdbad-db52-4586-87e1-40e4db581da5";
function GetCurrentItemID()
{
var ctx = SP.ClientContext.get_current();
var selectedItems = SP.ListOperation.Selection.getSelectedItems(ctx);
for (item in selectedItems)
{
var itemId = selectedItems[item].id;
startWorkflow(itemId, subID);
}
}
function startWorkflow(itemID, subID) {
var context = SP.ClientContext.get_current();
var web = context.get_web();
var wfServiceManager = SP.WorkflowServices.WorkflowServicesManager.newObject(context, web);
var subscription = wfServiceManager.getWorkflowSubscriptionService().getSubscription(subID);
context.load(subscription);
context.executeQueryAsync(
function(sender, args){
alert("Subscription load success. Attempting to start workflow.");
var inputParameters = {};
wfServiceManager.getWorkflowInstanceService().startWorkflowOnListItem
(subscription, itemID, inputParameters);
context.executeQueryAsync(
function(sender, args){ alert("Successfully starting workflow."); },
function(sender, args){
alert("Failed to start workflow.");
alert("Error: " + args.get_message() + "\n" + args.get_stackTrace());
}
);
},
function(sender,args){
alert("Failed to load subscription.");
alert("Error: " + args.get_message() + "\n" + args.get_stackTrace());
}
);
}
</script>
I am calling the GetCurrentItemID() function at the button click. But at that time, i am getting the following error.
Failed to load subscription
Invalid Request
Undefined
Could any one please help me to sort out this issue. Thanks in advance.

According to the script and the error message,
I suggest you check whether the “subscription” and “itemId” objects hold the proper values.
What’s more, you can take a look at the two links below about how to start workflow using JavaScript Client Object Model:
http://usamawahabkhan.blogspot.com/2013/07/start-workflow-sharepoint-2010.html
https://sharepoint.stackexchange.com/questions/87015/solved-start-a-workflow-of-the-host-web-via-sharepoint-app-and-jsom
Feel free to reply with the test result or if there are any progress.

Building on the solutions provided by others, here's the code I was able to use. NOTE: You need to have your workflow set to "Allow this workflow to be started manually."
/**

var ctx = new SP.ClientContext.get_current(),
wfsManager = SP.WorkflowServices.WorkflowServicesManager.newObject(ctx, ctx.get_web()),

ctx.load(wfSubs);
ctx.executeQueryAsync(function () {
