Reading iFrame content from javascript

[MarcelB]

Hi all,

Someone typed in some text in an iFrame, and then selected part of that text. Now how can I for instance display the selected part with an alert message?

I know I can get the whole text with:
iFramename.document.body.innerHTML


I also know there is the selection object/property, but I can't seem to get the right combination to be able to get the selected text.

Any help would be highly appreciated.

Thanx for the input, but it doesn't really, since the example given there selects ALL the text, while I'm searching for some piece of code that lets me do stuff with a selected piece of text from an iFrame, and only the selected text.

well couldn't you take the selected out and use the part where it stores the text to clipboard. other than that I don't think you will be able to do it. because if you search the forum you will see that this question was asked before and that was the answer that I showed you.

Well, I got it working, and the code for IE 4+ is:


--------------------------------------------------------------------------------

var range = myiFrameName.document.selection.createRange();
var str = range.text;

alert(str);

--------------------------------------------------------------------------------


Now my next question:
How do I replace the selected text, for instance to put it in bold?

Stuff like:

myiFrameName.document.selection.text = '<b>'+str+'</b>'
or
myiFrameName.document.selection.innerHTML = '<b>'+str+'</b>'

doesn't work.


Any ideas?

Okay, I got it to work as I wanted..
