function dynamicload_footer in Javascript Tools 5

Send settings to the browser.

We do this in the footer because some of the settings are theme-dependent. Typically, hook_footer will be called after the theme is initiated, so we have the correct theme to load data for.

File

dynamicload/dynamicload.module, line 171

Enable AJAX-based loading of selected page elements.

Code

function dynamicload_footer() {
  global $theme;
  static $loaded = FALSE;

    // Insert dummy content that will be used to select the region container.

    // The left and right regions are handled separately in dynamicload_load().
    unset($regions['left'], $regions['right']);
    _dynamicload_set_region_markers($regions);
    $settings = dynamicload_block_data();
    foreach (module_invoke_all('dynamicload') as $setting) {
