Even a device has active GPS it is possible that your JS code will not benefit from this, that because browsers will not let you know the location without permission from the user... The problem is that browsers remember the hoise for every site, so once the user voted 'no' you have no way to force him choose again...
But, there is one way may help you... Connect 'getCurrentPosition' - directly - to a button click, in this case it considered as an action by the user and will be permitted... Of course you have to exactly describe to the user what will happening what clicking the button...

Quote: How to find user device is gps is on or off Android or ios using js?
You are aware of the fact that GPS is a system feature in Android and not a browser feature, right? You can get the location, but to detect or determine you will have rely on the user, as browser won't be able to trigger changes itself.
Offline devices will return the most recent locations, not accurate or live locations. If you mean to say that location APIs are available then read here,
Common sources of location information include Global Positioning System (GPS) and location inferred from network signals such as IP address, RFID, WiFi and Bluetooth MAC addresses, and GSM/CDMA cell IDs, as well as user input. No guarantee is given that the API returns the device's actual location. So, you can simply request the users to enable GPS for better results.
Also, you should try to check for navigator.geolocation to be set to null or not, otherwise results may be generated.
if (navigator.geolocation) {
} else {
}

I'm trying to understand two way binding in AngularJS but I'm unable to understand the behavior of functions and variables.
Consider the following example:
So, I have a controller like this:
var app=angular.module("cal", []);
app.controller("calc",function ($scope) {
$scope.result=Number($scope.a || 0)+ Number($scope.b || 0);
});
and HTML like this:
<div ng-app="cal">
<div ng-controller="calc">
<input type="text" ng-model="a"/>
<input type="text" ng-model="b"/>
<span>{{result}}</span>
</div>
</div>
This code doesn't update the variable "result".
However, if I use something like this:
var app=angular.module("cal", []);
app.controller("calc",function ($scope) {
$scope.add = function(){
return (Number($scope.a || 0)+ Number($scope.b || 0));
}
});
and
<div ng-app="cal">
<div ng-controller="calc">
<input type="text" ng-model="a"/>
<input type="text" ng-model="b"/>
<span>{{add()}}</span>
</div>
</div>
the value in gets updated automatically with variation in variables "a" or "b".
How does this work? What's the difference in returning from the function and using the variable directly in the DOM?
|
|
|
|
|
There's a few ways to handle this, but since this is a basic operation you can do it directly in the angular tag. I would just advise declaring your scope properties in the controller for stability.
app.controller('calc',['$scope',function($scope){
$scope.a = 0;
$scope.b = 0;
});
<div ng-app="cal">
<div ng-controller="calc">
<input type="text" ng-model="a"/>
<input type="text" ng-model="b"/>
<span>{{ a + b }}</span>
</div>
</div>

I get this but this isn't what I asked. I want to know why using the variable "result" doesn't work. Doesn't Angular update it along with variables "a" and "b"?
|
|
|
|
|
Well, because you're assigning it as part of controller construction. If you want it to update then you'll need to watch the source variables:
app.controller('calc',['$scope',function($scope){
$scope.a = 0;
$scope.b = 0;
$scope.result = 0;
$scope.calculate = function(){
$scope.result = $scope.a + $scope.b;
}
$scope.$watch('a',$scope.calculate);
$scope.$watch('b',$scope.calculate);
});
Personally I think in this sort of operation that an aggregate variable is overkill, and it would be better to directly inject $scope.a and $scope.b into a request, if that's what you're goal is.

|
|
|
|
Yes, but why don't we have to watch in case of using "add()"? Does Angular watch for functions automatically and for using variables in view do we have to watch them manually?
|
|
|
|
|
Because you're binding to a function in the markup. That means that every time a digest cycle is run, that function is executed. That's definitely not the ideal way to bind, and potentially extremely buggy.
Have a look at the Scope Lifecycle section of:
AngularJS Developer's Guide[^]
The important thing to remember is that the page rendering (anything on the template) is processed when the $digest is run, so loading functions directly into it can become a very expensive process.

|
|
|
|
|
OK. What's the ideal way to bind?
|
|
|
|
|
If you absolutely need an aggregate from other scope properties bound to a scope property, the ideal way to bind is to $scope.$watch the base properties.
If you need a transform from a scope property, but do not need the result bound to a property (a totals row, for instance) the ideal way is either native functions or filters.
Methods should really be saved for event handling and processing.

What does this mean? Do you want multiple languages to show? Do you want the user to change the language? Are you translating everything?
Member 12847869 wrote: How to security a website professionally?
Is there a database back-end? What kind of server? IIS? Apache? Do you need to secure certain pages or the whole site? Is anonymous allowed?
Hopefully you can see that your question needs a ton more detail for anyone to help.

Thanks Mr. Richard MacCutchan. I followed that process I am able to login to facebook and google but I got nothing to import friends into my website. For facebook i used a code which provide me only list of friends to tag them not for chat. In google i used gapi.client.people.list but it returns item[] zero means no friends. For Skype they have mentioned that APIs are not public and same for whatsapp, So I can't login to skype and whatsapp. If you have solution please guide.
