Question

I am using the WebBrowser control in Windows Phone to invoke a javascript call. Right now, the code works fine when I reference the script online. However, when I reference it locally, it breaks.

I am thinking it has something to do with isolated storage and how WP7 apps install, but I wanted to get others takes.

The HTML file contains:

<script type="text/javascript" src="scripts/myJavascript.js"></script>

it works just fine when I do

<script type="text/javascript" src="http://mysite.com/myJavascript.js"></script>'

And idea how I can reference the file locally? I have it set to Content and Copy Always.

In the end, the real file is http://closure-library.googlecode.com/svn/trunk/closure/goog/base.js
I need to get it to work offline so my users don’t need an internet connection to use my app.

Thanks!

I cannot immediately see an issue with your approach, however, you have not shown the code you use to load the files into local storage. I would recommend looking at the sourcecode for PhoneGap, which loads multiple files into isolated storage for rendering in a WebBrowser, to see how it does it. Here is the relevant opart of the PhoneGap code:

fileResourceStreamInfo = Application.GetResourceStream(new Uri(file.path, UriKind.Relative));

if (fileResourceStreamInfo != null)
{
    using (BinaryReader br = new BinaryReader(fileResourceStreamInfo.Stream))
    {
        byte[] data = br.ReadBytes((int)fileResourceStreamInfo.Stream.Length);

        string strBaseDir = AppRoot + file.path.Substring(0, file.path.LastIndexOf(System.IO.Path.DirectorySeparatorChar));

        if(!appStorage.DirectoryExists(strBaseDir))
        {
            //Debug.WriteLine("Creating Directory :: " + strBaseDir);
            appStorage.CreateDirectory(strBaseDir);
        }

        // This will truncate/overwrite an existing file, or 
        using (IsolatedStorageFileStream outFile = appStorage.OpenFile(AppRoot + file.path, FileMode.Create))
        {
            Debug.WriteLine("Writing data for " + AppRoot + file.path + " and length = " + data.Length);
            using (var writer = new BinaryWriter(outFile))
            {
                writer.Write(data);
            }
        }
    }
}
