[OpenLayers-Users] Problem dynamic loading a KML file (refresh)

Sun Nov 11 12:46:31 PST 2012

you try to get an url for a kmlfile with input type="file" (lets you choose
a file in your filesystem and not an url), which delivers in Firefox only
the filename without the path. As far as you load a file from the same path
as your page, this will work on your local system.

In IE and Chrome a fakepath is added to the filename.

That' from Chrome
Not allowed to load local resource:
file:///C:/fakepath/Santiago_Calatrava.kml

and with IE it's the same.

Add an alert(filename) to your function AddLayer() to see what will
returned.

Good luck

I changed it this way;

<!DOCTYPE html>

<html>

	<head>

		<title>Loading a KML File</title>

		<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8">

		<script type="text/javascript" src="OpenLayers.js"></script>

	<style>

	<!--

		html, body 

		{

			width: 100%;

			height: 100%;

			margin: 0;

			padding: 0;

		}

	-->

	</style>

	<script type="text/javascript">

	var filename = "";

	var map;

	var kml_layer;

	function init() 

	{		

		var options = 	{

			minResolution: "auto",

			minExtent: new OpenLayers.Bounds(-1, -1, 1, 1),

			maxResolution: "auto",

			maxExtent: new OpenLayers.Bounds(-180, -90, 180,
90),

			controls: [

			new
OpenLayers.Control.LayerSwitcher({'ascending':false}),

			new OpenLayers.Control.Navigation(),

			new OpenLayers.Control.PanZoom(),

			new OpenLayers.Control.KeyboardDefaults()

			],

			numZoomLevels: 19,

			units: 'm',

			projection: new
OpenLayers.Projection("EPSG:900913"),

			displayProjection: new
OpenLayers.Projection("EPSG:4326")

		};

		map = new OpenLayers.Map("map", options);

		var osm_layer = new OpenLayers.Layer.OSM();

		map.addLayer(osm_layer);

		kml_layer = new OpenLayers.Layer.Vector("KML", {

			projection: map.displayProjection,

			strategies: [new OpenLayers.Strategy.Fixed()],

			protocol: new OpenLayers.Protocol.HTTP({

				url: filename,

				format: new OpenLayers.Format.KML({

					extractStyles: true,

					extractAttributes: true,

					maxDepth: 10

				})

			})

		});

		map.addLayer(kml_layer);

		map.zoomToMaxExtent();	

	}

	function AddLayer()

	{

		// get KML file

		filename = document.getElementById('theFile').value;

		if(filename == "")

		{

			alert("Select KML file");

		}

		else

		{

			kml_layer.refresh({url: filename });

		}			

	}

	</script>

	</head>

	<body onload="init()">

	    <div id="top" style="width: 100%; height: 15pt; padding: 5px;">

			<input type="file" id="theFile" size="100" />

			<input type="button" value="Show Markers"
onClick="AddLayer()">

		</div>

		<div id="map" style="width: 100%; height: 100%;"></div>

	</body>

</html>

Works excellent in Mozilla Firefox but again not in IE and Chrome.

Error message in IE:

Webpage error details

This part from OpenLayers.js

What's going wrong ????
