I get some data from JSONP file by below code:
$.getJSON('http://static.eska.pl/m/playlist/channel-108.jsonp?callback=?' );
function jsonp(data) {
document.getElementById("artist").innerHTML = data[0].artists[0].name;
document.getElementById("title").innerHTML = data[0].name;
};
<!DOCTYPE html>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<div id="artist"></div>
<div id="title"></div>
</body>
</html>
It works, but I need refresh data every 10 sec. I use setInterval function but console FireFox return error "ReferenceError: jsonp is not defined
(...channel-108.jsonp:1:1)". My code with setInterval:
setInterval( function () {
$.getJSON('http://static.eska.pl/m/playlist/channel-108.jsonp?callback=?' );
function jsonp(data) {
document.getElementById("artist").innerHTML = data[0].artists[0].name;
document.getElementById("title").innerHTML = data[0].name;
};
}, 10000)

Where's the problem?
You are declaring the function inside the setInterval move it outside and it will work
function jsonp(data) {
document.getElementById("artist").innerHTML = data[0].artists[0].name;
document.getElementById("title").innerHTML = data[0].name;
};
setInterval(function() {
$.getJSON('http://static.eska.pl/m/playlist/channel-108.jsonp?callback=?');
}, 10000)

i am new to coding and i am starting with angular js....
i have a json like below
$scope.data={
"items":
{
"yamaha":
{
"title":"R15",
"description":"sports mode",
"speed":"180kmph"
},
"Tvs":
{
"title":"apache",
"description":"sports mode",
"speed":"150kmph"
}
}
};
now my requirement is to show each value one after other in html.....
Note
As i said i am new,i have googled this and found some info like ng-repeat but i didnt understand how to use this in while implementing.
thanks for your response
ng-repeat will iterate over the data in the given array....here i used key,vakue concept to print object keys and values

Im trying to get data from an endpoint api/data which passes an object. But when I run my app I dont see anything in my console and in the network tab I dont see any xhr request. There is no warning and errors in console too. Am I doing anything wrong here? I have checked the endpoint and its passing data from backend properly.

Your ready hook is inside methods: {} handler but in reality should be outside:
methods: {
fetchData: function () {

}
},
ready: function () {
this.fetchData()
}
my json file looks like

I am getting uncaught exception- No data error
Before plotting the chart, I am printing the array and there are all the values that I need.
What is missing? Where am I doing wrong?
Thanks for your help.
I don't understand why you are feeding data to the objArrayData array in the way you are doing here. The data doesn't become an array just because there are square brackets surrounding them (it will only appear pretty and satisfying and confusing in the cosole.log).
Use array.push() instead of the way you are doing it here.
And also make sure you make the data.scoreAverage a number before parsing it to the array.
You can do it using parseFloat() function.
So finally you can feed the data to the array like this.
objArrayData.push([data.date,parseFloat(data.scoreAverage)]);
Here's the modified working code.

Hope this helps.
PS: Make sure you learn about arrays a little more.
i finished my app but when i test it on the other internet browsers, there was a problem
i will add my code. i couldnt see the error.as i said it works on opera but not in firefox :/

You are loading the Facebook JS SDK in async mode and thus the FB object is not ready when you call it inside lget, the async loading occurs after your calls to lget and even after the onload event in Firefox.
Try not loading the code asynchronously and note that it is working fine

if you want to see the execution order try something like this
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2011/fbml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body onload="console.log('onload event'); false;">
<div id="fb-root"></div>
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({appId: '199193070140222', status: true, cookie: true, xfbml: true});
console.log('FB object ready');
};
(function() {
var e = document.createElement('script');
e.type = 'text/javascript';
e.src = document.location.protocol +
'//connect.facebook.net/tr_TR/all.js';
e.async = true;
document.getElementById('fb-root').appendChild(e);
console.log('This executed first');
}
());
function lget(idd){
console.log('lget - ' + idd);
};

<script type="text/javascript">
lget(534018674);
</script>
</div>
</body>
</html>
this is the output you'll get in Firefox
This executed first
lget - 525864081
lget - 534018674
onload event
FB object ready
