function _batch_progress_page_js in Drupal 7

Same name and namespace in other branches

1. 6 includes/batch.inc \_batch_progress_page_js()

Outputs a batch processing page with JavaScript support.

This initializes the batch and error messages. Note that in JavaScript-based processing, the batch processing page is displayed only once and updated via AHAH requests, so only the first batch set gets to define the page title. Titles specified by subsequent batch sets are not displayed.
