Question

Are you having the same problems I am with Webviews?

I am using Titanium 1.21 and Android 2.1.

To summarize the main problems I am facing:

1) Cannot get data from a webview to app.js

I've spent 2 days on this now, and nothing works. If I try to use evalJS, I get a forced close in the emulator. If I try to simply define a variable in the window like win1.something='abcd', I cannot retrieve it inside the webview.

2) Fireevent gets fired at least 2 times

This has been in the forum for a few weeks now, any idea when it's going to get fixed?

Anyone knows the status of these?

Answer 1

i have/had a simlar issue took 3 days to figure it out, with not luck from the forum.
I used something like this. (basiclly a details screen pushing data to a webview. I'm sure you could reverse it


                    webview.addEventListener('load', function()
                     {
                            Ti.App.fireEvent('pageReady',{id:MyVar}); // sets the var to pass

                    });    
                    w.add(webview);
                    w.open();
.... more code here

then in the HTML page in the <script> tags I used:

Ti.App.addEventListener('pageReady',function(e) // catches the passed var
    {
        alert('the id is' + id); // shows ID idin debugger.
        id = (set var here)

    {

Not sure if this will help, I can't seem to find the example I used to refer to.

Hope it helps

Answer 2

But why should we work with ugly workarounds, if this feature should work on both platforms the same, according to Passind Data section in window documentation

i have this feeling that the iPad hype will let us wait long for a fix of this obvious bug in android implementation. And thats maybe the answer why we need ugly workarounds ;)

someone else an idea?

thx, bye.
