    Guys, I am creating an Android-Phonegap app using Eclipse IDE. I have created an HTML file containbing an image and 2 buttons. I have written the following code inside html file.
    <!DOCTYPE HTML>
    <HTML lang="en">

    <HEAD>
    <meta charset="utf-8"/>
    <script type="text/javascript" charset="utf-8" src="cordova-1.9.0.js"></script>
    <script type="text/javascript" charset="utf-8">
    function onLoad() {
    document.addEventListener("deviceready", onDeviceReady, false);

    }

    // Cordova is loaded and it is now safe to make calls Cordova methods
    //
    function onDeviceReady() {
    // Now safe to use the Cordova API

    Obj.addEventListener('touchstart', function(event) {
    // If there's exactly one finger inside this element
    if (event.targetTouches.length == 1) {

    alert("HI");
    }
    }, false);
    }
    var Obj = document.getElementById('id');

    function zoom()
    {
    alert("hi");
    imgGirl.height+=10;
    imgGirl.width+=10;
    }
    function zoomOut()
    {
    imgGirl.height-=1;
    imgGirl.width-=1;
    }
    </SCRIPT>
    </HEAD>

    <BODY onLoad="onLoad()">Hello

    <img id="imgGirl" SRC="MyGirl.jpg" height="50" width="50"/>

    <button id="btnZoomIn" type="button" onClick="zoom()">ZoomIn</button>
    <button id="btnZoomOut" type="button" onClick="zoomOut()">ZoomOut</button>


    <nav>
    <a href="home.html">Home </a>

    </nav>

    </BODY>
    </HTML>

    When I run my app on Android emulator and click the buttons, I get Uncaught reference error in file. the say, "zoom and zoomOut" is undefined.plz help.its urgent.It does not produce any of the dialog boxes.

    I've moved your thread to the Application Development forum where you will get better help.:)

    It is a good idea to edit your post and enclose the code in [code][/code] to make it more readable for other members.
