Range.deserializeSelection checksum error?

It's a followup question of this. I've serialized the selection of text in an iframe and want to restore it but it gives me an error, "Uncaught Error: deserializeRange: checksums of serialized range root node (XXXXX) and target root node (XXXXX) do not match"

var iframe = $("iframe")[0];
var selection = rangy.getSelection(iframe);
var serializeSelection = rangy.serializeSelection(selection);
alert(serializeSelection);
rangy.deserializeSelection(serializeSelection);

Solution

  • You need to provide the window object as the third parameter:

    rangy.deserializeSelection(serializeSelection, null, iframe.contentWindow);

    This is more awkward than it should be. Version 1.3 allows you to use iframe rather than iframe.contentWindow, but it's still too unreadable so I will improve this somehow.
