IE doesn't accept periods or dashes in the window name, but the element IDs we use to generate popup window names may contain them, therefore we map them to allowed characters in a reversible way so that we can locate the correct element when the popup window is dismissed.
var id_to_windowname = function(text) {
text = text.replace(/\./g, '__dot__');
text = text.replace(/\-/g, '__dash__');
text = text.replace(/\[/g, '__braceleft__');
text = text.replace(/\]/g, '__braceright__');
return text;
}
var windowname_to_id = function(text) {
text = text.replace(/__dot__/g, '.');
text = text.replace(/__dash__/g, '-');
text = text.replace(/__braceleft__/g, '[');
text = text.replace(/__braceright__/g, ']');
return text;
}
$( '.autocomplete-add-another' ).show().click(function(e) {
e.preventDefault( );
showAddAnotherPopup( $( this ) );
});
