Serialize Selection object?

[greenman]

Hello,

Is there a chance to serialize a selection/range object (holding the selected by the user text fragment) on a webpage, so that I could deserialize it later on
this site and make this selection/range programatically or apply a different style to it?

Regards,
g.

it has an example for Mozilla and Opera to store teh selection in a
cookie and restore it.

Hi,

Serializing isn't difficult.
Just think up 2 seperators you don't use in the selectbox, eg:
| means seperator between name and value
# means seperator between different entries.

Then you'll end up with a string like:
10|low#20|medium#30|high
for
<select name="bla">
<option value="10">low
<option value="20">medium
<option value="30">high
</select>

But where do you want to store this serialized string?
In a cookie?

Can you program serverside? That could make more sense.
Serverside you could use an include for a complex select, that needs for
example a lot of database activity to produce.
Please give more information so we can help you better.

Many thanks for this answer!

The script on http://home.arcor.de/martin.honnen/j...election1.html works really impressive, and - together with Your post on
mozilla.dev.tech.dom - that was exactly the approach I was looking for.

Best regards,

Hi,

I meant the DOM:Selection object. I asked because no javascript serializing class I found recognized this type of object. But then I realized, it's - like You
said - all about certain properties (anchorNode, anchorOffset, focusNode, focusOffset), which I can obviously read, build 2 xpath expressions, and send to the
server, and then read from the server to recreate the selection on page.

Thanks and regards,
g.
