Phonegap:Childbrowser not working - ios

Question

I am working with ios phonegap application. I created a new project with phonegap2.4.0.
It was success.But my issue is childbrowser is not coming and shows following error in console:
OPENING URL:INVALID
I have done all the steps needed to include a childbrowser in the project and it is working fine in an old phonegap project.
How can i fix the problem??
function onBodyLoad() {
document.addEventListener("deviceready", onDeviceReady,false);
}
function onDeviceReady() {
cb = ChildBrowser.install();
}
function helo() {
alert("hiiii");
cordova.exec(null,null,"ChildBrowser","showWebPage",['google.com']);
}

Answer 1

function onDeviceReady() {
if(window.plugins.childBrowser == null)
{
ChildBrowser.install();
}
}
Or You can use InAppBrowser instead of childbrwoser.
For close browser use ref.close();
var ref = window.open("google.com", 'random_string', 'location=no');
ref.addEventListener('loadstart', function(event) {
console.log(event.type + ' - ' + event.url);
} );
ref.addEventListener('loadstop', function(event) {
console.log(event.type + ' - ' + event.url);
} );
ref.addEventListener('exit', function(event) {
//alert(event.type);
} );
