Question

Webviews and fireEvent

Is there anyway to return a value to the webview after a fireEvent has been called? I don't want to use evalJS…

This is a quick test tried (which obviously doesn't work but it gives you an idea):

In my webview:

function test(){
 alert(Titanium.App.fireEvent('test'));
}

In my local js:

Titanium.App.addEventListener('test', function(e){
    Ti.API.info('Test local');
    return 'Test webview';
});

Is there a way to do anything like this? I know I can do something similar with evalJS, but it won't work quite the way I want it to….

Answer 1

You need to setup a callback function, another event to fire back at the original file.

Titanium.App.addEventListener('01', function(e){
   // do something
   Titanium.App.fireEvent('02', {return_value: 'return value'});
});

Titanium.App.addEventListener('02', function(e){
   // do something with e.return_value;
});

Ti.App.fireEvent('01');
