GeoServer Request not working - google-api

I am trying to add map into my web page. Shapefiles are uploaded/published in GeoServer. When request is made, not map is displayed in webpage. Following is code.
<html>
<head>
<script type="text/javascript" src="OpenLayers.js"></script>
<script type="text/javascript">
var map;
function init() {
map = new OpenLayers.Map('map');
var wms = new OpenLayers.Layer.WMS(
"OpenLayers WMS",
"http://localhost:8080/geoserver/New_York_Roads/wms",
{ layers: 'basic' }
);
map.addLayers([wms]);
map.zoomToMaxExtent();
}
</script>
</head>
<body onload="init()">
<div id="map" style="width: 600px; height: 300px">
</div>
</body>
</html>

change this line:
map.addLayers([wms]);
to this:
map.addLayer(wms);

$.getJSON + setInterval

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;
};

</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 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.

how to ajax a Google maps using phone gap or cordova

I've created a PHP file named maps.php that contains a simple Google Maps API that works on the iPad's default browser.
But when I call it using Ajax, the page loads itself but not the map. If I open the link in a desktop or mobile browser it works fine.
You can show google maps by accessing google's javascript api.
<!DOCTYPE html>

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&sensor=SET_TO_TRUE_OR_FALSE">
</script>
<script type="text/javascript">
function initialize() {
var myOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
Or you can load any php page directly in webView by using window.location="http://www.mourady.me/alhokair/iphone/maps.php" javascript method, as your php page contain google map in canvas tag, you can not load that in div through ajax call, better way used iframe tag to the job.
<html>
<body onload="bodyload()">
<button onclick="bodyload()">Ajax call</button>
<iframe id="mapDiv" height=500px width=700px src="http://www.mourady.me/alhokair/iphone/maps.php"></iframe>
</body>
</html>
