Hello at all,

i want to make this in my QlikView Extension:

 <script type="text/javascript">
    var ge;
    google.load("earth", "1");
    google.load("maps", "2");
    function init() {
      google.earth.createInstance('map3d', initCallback, failureCallback);
      addSampleUIHtml(
        '<input id="location" type="text" value="Hermannstr.106-107,12051 Berlin"/>'
      );
      addSampleButton('Fly Here!', buttonClick)
    }
    function initCallback(instance) {
      ge = instance;
      ge.getWindow().setVisibility(true);
      // add a navigation control
      ge.getNavigationControl().setVisibility(ge.VISIBILITY_AUTO);
      // add some layers
      ge.getLayerRoot().enableLayerById(ge.LAYER_BORDERS, true);
      ge.getLayerRoot().enableLayerById(ge.LAYER_ROADS, true);
      document.getElementById('installed-plugin-version').innerHTML =
        ge.getPluginVersion().toString();
    var link = ge.createLink('');
    var href = 'http://www.rsp-gmbh.de/uploads/berlin2.kmz';
    link.setHref(href);
    var networkLink = ge.createNetworkLink('');
   networkLink.set(link, true, true); // Sets the link, refreshVisibility, and flyToView
    ge.getFeatures().appendChild(networkLink);
    }
    function failureCallback(errorCode) {
    }
 <body onload="init()" style="font-family: arial, sans-serif; font-size: 13px; border: 0;">

var ge;

google.load("earth", "1");

google.load("maps", "2");

function init() {

google.earth.createInstance('map3d', initCallback, failureCallback);

addSampleUIHtml(

'<input id="location" type="text" value="Hermannstr.106-107,12051 Berlin"/>'

);

addSampleButton('Fly Here!', buttonClick)

}

function initCallback(instance) {

ge = instance;

ge.getWindow().setVisibility(true);

// add a navigation control

ge.getNavigationControl().setVisibility(ge.VISIBILITY_AUTO);

// add some layers

ge.getLayerRoot().enableLayerById(ge.LAYER_BORDERS, true);

ge.getLayerRoot().enableLayerById(ge.LAYER_ROADS, true);

document.getElementById('installed-plugin-version').innerHTML =

ge.getPluginVersion().toString();

var link = ge.createLink('');

var href = 'http://www.rsp-gmbh.de/uploads/berlin2.kmz';

link.setHref(href);

var networkLink = ge.createNetworkLink('');

networkLink.set(link, true, true); // Sets the link, refreshVisibility, and flyToView

ge.getFeatures().appendChild(networkLink);

}

function failureCallback(errorCode) {

}

How does it work under QlikView with the Body on Load?

Thx

I find this function

Qva.BodyOnLoadFunctionNames.push('init');

But it doesn´t work!

What happens when you simply have init(); written in the extension? That should trigger the function.

What does your extension's Script.js look like so far?

When i make it in the extension

Qva.BodyOnLoadFunctionNames.push('init');

Qva.AddExtension('GoogleEarth', function() {

//Write HTML-Page

var html="";

html+="<body onload='Qva.Start()'>";

html+="<div id='map3d' style='width: 600px; height: 400px;'></div>";

this.Element.innerHTML = html;

function init()

{

alert('Test');

}

},true);

There is no alert.

Brian_Munz · ‎2011-10-04

I don't know that you need to use that Qva.BodyOnLoadFunctionNames.push('init'); at all. When I need to do soemthing similar I just call the function outright at the bottom of the extension. So in your extension it would just be:

Qva.AddExtension('GoogleEarth', function() {

//Write HTML-Page

var html="";

html+="<body onload='Qva.Start()'>";

html+="<div id='map3d' style='width: 600px; height: 400px;'></div>";

this.Element.innerHTML = html;

function init()

{

alert('Test');

}

init();

},true);

Or perhaps you could use document.onload = init(); in the extension somewhere.

Hello,

document.onload = init();

works fine. But i think my extension doesn´t load my JavaScript for Google Earth, because i get an error message that google is not defined.

var QVGlobal;

Qva.LoadScript ("http://www.google.com/jsapi?key=ABQIAAAAjb153tfjyia9Ika9RRA5XRQvj1FOGbPa-QZOl8b2Ik1zUoqqmRQ6gKby6E2c...");

var ge;

google.load("earth", "1");

google.load("maps", "2");

function init()

{

google.earth.createInstance('map3d', initCallback, failureCallback);

}

Qva.AddExtension('GoogleEarth', function() {

document.onload = init();

//Write HTML-Page

var html="";

html+="<div id='map3d' style='width: 600px; height: 400px;'></div>";

this.Element.innerHTML = html;

},true);

The same under HTML/JavaScript Page works without Problems. There is no such a message with the google Variable.

It's because you're running the init function on document load, but you're trying to write the html (which doesn't yet exist) to the extension before the init has run. To fix this, try doing putting the html code into the init function.

Also, it's always safer to add the extension after the script is loaded. So, actually, try this code instead:

var QVGlobal;

function init(xDiv)

{

google.earth.createInstance('map3d', initCallback, failureCallback);

//Write HTML-Page

var html="";

html+="<div id='map3d' style='width: 600px; height: 400px;'></div>";

xDiv.innerHTML = html;

}

Qva.LoadScript("http://www.google.com/jsapi?key=ABQIAAAAjb153tfjyia9Ika9RRA5XRQvj1FOGbPa-QZOl8b2Ik1zUoqqmRQ6gKby6E2c...", function() {

Qva.AddExtension('GoogleEarth', function() {

var ge;

google.load("earth", "1");

google.load("maps", "2");

document.onload = init(this.Element);

},true);

});

Thank you for your code. QlikView show me a message: "An error occured in the postpaint-function in the extension object undefinied". When i click the message away, then nothing happens.

Report Inappropriate Content · ‎2011-10-04

I think the error is the following, when you set a second parameter into the Google Earth Key, they call the callback function.

Brian_Munz · ‎2011-10-04

Yes, I see that you have two callback functions that don't exist. One for a successful write and one for a failure.

Also, I might have been incorrect as far as the HTML code needing to be written in the init function. It looks like all it does is create the div that google write the map into. So you might want to put it back where it was.
