Window.onload works, but the Chrome console says: Uncaught TypeError: window.onload is not a function

Question

I want to run the method getLocation()when the page loads. I added: window.onload(getLocation());and the function is called as I wish, but the Chrome console says:

 Uncaught TypeError: window.onload is not a function(anonymous function) @ (index):116

---

The view window.onload(getLocation());is below:

@{
    ViewBag.Title = "Home Page";
}


<div id="demo"></div>
<h2>Gecoding Demo JavaScript: </h2>
<div id="map" style="height: 253px ; width: 253px" />


@section Scripts {
    <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
    <script>
        var x = document.getElementById("demo");
        function getLocation() {
            if (navigator.geolocation) {
                var position = navigator.geolocation.getCurrentPosition(showPosition);

            } else {
                x.innerHTML = "Geolocation is not supported by this browser.";
            }
        }
        function showPosition(position) {
            x.innerHTML = "Latitude: " + position.coords.latitude +
            "<br>Longitude: " + position.coords.longitude;
            InitializeMap(position)
        }
        var map;
        var geocoder;
        function InitializeMap(position) {

            alert(position.coords.latitude+"");
            var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
            var myOptions =
            {
                zoom: 8,
                center: latlng,
                mapTypeId: google.maps.MapTypeId.ROADMAP,
                disableDefaultUI: true
            };
            map = new google.maps.Map(document.getElementById("map"), myOptions);
        }

        window.onload(getLocation());
    </script>
}

As you wrote your code, it does not work onload, it just works when the parser hits it. Since you wrote getLocation(), and not only getLocation, it performs this function.

, , window.onload=getLocation;. , ( /), , - :

window.addEventListener('load', getLocation);

, IE8. IE8, addEventListener(), , attachEvent():

   if (window.addEventListener) {
      window.addEventListener('load', getLocation);
   } else if (window.attachEvent) {
      window.attachEvent('onload', getLocation);
   } else { 
      window.onload = getLocation;
   }
