Javascript – How to get email address field using the LinkedIn Javascript API

apijavascriptlinkedin

I'm using the LinkedIn Javascript API to sign in users to my application, however the API is not returning the email address even though I'm requiring permission for that specific field. I'm including the API script as follows:

<script type="text/javascript" src="//platform.linkedin.com/in.js">
  api_key: API_KEY
  scope: r_fullprofile r_emailaddress
</script>

then I'm including the Log In button in the markup:

<script type="in/Login" data-onAuth="onLinkedInAuth">

and finally I have a function to add the callback for the API response:

function onLinkedInAuth() {
    var fields = ['first-name', 'last-name', 'email-address'];

    IN.API.Profile("me").fields(fields).result(function(data) {
        console.log(data);
    }).error(function(data) {
        console.log(data);
    });
};

I'm only getting the First and Last Name but the API doesn't return the email field.

1- be sure you made email permission (r_emailaddress) in your app http://developer.linkedin.com/documents/authentication#granting

2- then you may use this

    <script type="text/javascript" src="http://platform.linkedin.com/in.js">
        api_key: key
        **onLoad: onLinkedInLoad**
        authorize: true
    </script>

    <script>



        function onLinkedInLoad() {
            IN.Event.on(IN, "auth", onLinkedInAuth);
        }

        // 2. Runs when the viewer has authenticated
        function onLinkedInAuth() {

            IN.API.Profile("me").fields("first-name", "last-name", "email-address").result(function (data) {
                console.log(data);
            }).error(function (data) {
                console.log(data);
            });
         }
</script>

hope this will help you :) thanks

Javascript – How to validate an email address in JavaScript

Using regular expressions is probably the best way. You can see a bunch of tests here (taken from chromium)

function validateEmail(email) {
    const re = /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(String(email).toLowerCase());
}

Here's the example of regular expresion that accepts unicode:

const re = /^(([^<>()[\]\.,;:\s@\"]+(\.[^<>()[\]\.,;:\s@\"]+)*)|(\".+\"))@(([^<>()[\]\.,;:\s@\"]+\.)+[^<>()[\]\.,;:\s@\"]{2,})$/i;

But keep in mind that one should not rely only upon JavaScript validation. JavaScript can easily be disabled. This should be validated on the server side as well.

Here's an example of the above in action:

function validateEmail(email) {
  const re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
  return re.test(email);
}

function validate() {
  const $result = $("#result");
  const email = $("#email").val();
  $result.text("");

  if (validateEmail(email)) {
    $result.text(email + " is valid :)");
    $result.css("color", "green");
  } else {
    $result.text(email + " is not valid :(");
    $result.css("color", "red");
  }
  return false;
}

$("#email").on("input", validate);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<label for=email>Enter an email address:</label>
<input id="email">
<h2 id="result"></h2>

Javascript – How to get a timestamp in JavaScript

Short & Snazzy:

+ new Date()

A unary operator like plus triggers the valueOf method in the Date object and it returns the timestamp (without any alteration).

Details:

On almost all current browsers you can use Date.now() to get the UTC timestamp in milliseconds; a notable exception to this is IE8 and earlier (see compatibility table).

You can easily make a shim for this, though:

if (!Date.now) {
    Date.now = function() { return new Date().getTime(); }
}

To get the timestamp in seconds, you can use:

Math.floor(Date.now() / 1000)

Or alternatively you could use:

Date.now() / 1000 | 0

Which should be slightly faster, but also less readable.
(also see this answer or this with further explaination to bitwise operators).

I would recommend using Date.now() (with compatibility shim). It's slightly better because it's shorter & doesn't create a new Date object. However, if you don't want a shim & maximum compatibility, you could use the "old" method to get the timestamp in milliseconds:

new Date().getTime()

Which you can then convert to seconds like this:

Math.round(new Date().getTime()/1000)

And you can also use the valueOf method which we showed above:

new Date().valueOf()

Timestamp in Milliseconds

var timeStampInMs = window.performance && window.performance.now && window.performance.timing && window.performance.timing.navigationStart ? window.performance.now() + window.performance.timing.navigationStart : Date.now();

console.log(timeStampInMs, Date.now());
