Creating an HTML Client Application

This sample demonstrates how to incorporate TerraExplorer COM capabilities into a web page using the SGWorld object that gives you access to all of its main interfaces.

<html>

function Init() {

// To use the latest version of SGWorld

var sgworld = initSGWorld("");

// To use a specific version of SGWorld

// var SGWorld = initSGWorld("3a4f91a0-65a8-11d5-85c1-0001023952c1");

// Safety check: If SGWorld fails to initialize, exit the function

if (sgworld == null) return;

sgworld.Navigate.ZoomIn();

}

function initSGWorld(clsid) {

try {

if (sgworld)

return SGWorld.CreateInstance(clsid);

}

catch (e) { }

// Fusion

if (parent && parent. sgworld) {

return parent.SGWorld.CreateInstance(clsid);

}

// Desktop

try {

// try IE

var obj = document.createElement('object');

obj.setAttribute('id', '__sgworld_ie__');

obj.setAttribute('classid', 'CLSID:3a4f91a0-65a8-11d5-85c1-0001023952c1');

document.body.appendChild(obj);

return __sgworld_ie__.CreateInstance(clsid);

} catch (e) { } //Not IE

try {

// Try Edge

return __sgworld__.CreateInstance(clsid)

} catch (e) { } // Not Edge

return null;

}

</script>

</body>

</html>
