First, I want to thank you for the efforts in answering.
Second, I created a site that contains a plug-in of Google Earth, and I use a KML string to show two coordinates. i want to look at longitude -122.084075, latitude 37.4220033612141. when i load my website i don't see any changes.
my html code + the kml string:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"> </script>
<script type="text/javascript">
var ge;
google.load("earth", "1", {"other_params":"sensor=false"});
function init()
{
google.earth.createInstance('map3d', initCB, failureCB);
}
function initCB(instance)
{
ge = instance;
ge.getWindow().setVisibility(true);
addKmlFromString(

);
}
function addKmlFromString(kmlString)
{
var kmlObject = ge.parseKml(kmlString);
ge.getFeatures().appendChild(kmlObject);
}
function failureCB(errorCode)
{
}
google.setOnLoadCallback(init);

please guide me. what am i doing wrong? Thanks a lot!
I found the answer right here: https://developers.google.com/earth/documentation/camera_control#flytospeed
Zooming the camera
Zooming in and out is controlled by the range attribute for a LookAt, and the altitude attribute for a Camera.
Note that changing the altitude attribute of a LookAt changes the altitude of the point being viewed. Because the viewer range is relative to this point, the viewer's altitude is also changed.
LookAt:
// Get the current view.
var lookAt = ge.getView().copyAsLookAt(ge.ALTITUDE_RELATIVE_TO_GROUND);
// Zoom out to twice the current range.
lookAt.setRange(lookAt.getRange() * 2.0);
// Update the view in Google Earth.
ge.getView().setAbstractView(lookAt);
