  <script type="text/javascript">

    var ge;

var x=38;

var y=116;

    function init() {

      google.earth.createInstance('map3d', initCB, failureCB);

    }



    function initCB(instance) {

      ge = instance;

      ge.getWindow().setVisibility(true);

 ge.getNavigationControl().setVisibility(ge.VISIBILITY_SHOW);



    }

function locate(){

 x=document.getElementById("latitude").value;

 y=document.getElementById("longitude").value;

alert(x);

alert(y);

var lookAt = ge.createLookAt('');



// Set the position values.

lookAt.setLatitude(x);

lookAt.setLongitude(y);

lookAt.setRange(100.0); //default is 0.0



// Update the view in Google Earth.

ge.getView().setAbstractView(lookAt);

}

    function failureCB(errorCode) {

    }



    google.setOnLoadCallback(init);

<body>

<input value=36 id="latitude" />经度

<input value=118 id="longitude" />纬度

 

<input type="button" onclick="locate()">

  <div id="map3d" style="height: 600px; width: 800px;"></div>
