Extension not working in Chrome 24

[Chao Huang]

I use the following lines to define BlobBuilder object and slice function in Chrome extension

    window.BlobBuilder = window.BlobBuilder || window.WebKitBlobBuilder;

Blob.prototype.slice = Blob.prototype.slice || function(start, length) {
    return this.webkitSlice(start, start + length);
}

It works in Chrome with version up to 23, but for the latest version 24, it does not recognize my definitions any more. For example, var builder = new BlobBuilder() will prompt an error: Uncaught TypeError: undefined is not a function.

Does anyone know what's going on here? Thanks!

Perhaps your problem is related to change in Blob...BlobBuilder has been changing:

"In the course of standardization, the BlobBuilder API was removed in
favor of just using the Blob constructor. " -- http://trac.webkit.org/changeset/128797 (and the follow up http://trac.webkit.org/changeset/130343).

So it looks like WebkitBlobBuilder was removed and the replacement is just using the Blob constructor.
