please , let me know seems error

the issue because geolocation.getcurrentposition call asynchronous, hence you're trying use lat , long both before defined , out of scope.

to fix need put $.getjson call within callback of geolocation logic, this:

$(document).ready(function() {   var long;   var lat;    if (navigator.geolocation) {     navigator.geolocation.getcurrentposition(function(position) {       long = position.coords.longitude;       lat = position.coords.latitude;       $("#data").html("latitude: " + lat + "<br>longitude: " + long);        var api = 'https://api.openweathermap.org/data/2.5/weather?lat=' + lat + '&lon=' + long + '&appid=7cc72055cf03c02e9bf988f2a7b7b7e2';       $.getjson(api, function(data) {         console.log(data.coord.lon);         console.log(data);       });     });   } }); 
html {   background: url(http://s1.picswalls.com/wallpapers/2016/06/06/beach-desktop-background_090607928_305.jpg)center center fixed;   background-size: cover; }  header {   font-family: lobster;   color: white;   font-size: 40px;   text-align: center;   margin: 40px;   font-weight: bold; }  p {   color: white; } 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <header>local weather</header> <p id="data"></p>
