GetSelection code testing

[Dimitris Papageorgiou]

I want to test a GetSelection code.

The code is the following:

function GetSelectedText () {
            if (window.getSelection) {  // all browsers, except IE before version 9
                var range = window.getSelection ();                                        
                alert (range.toString ());
            }} 
This code assumes that a text segment is selected in a webpage.
The console seems that it does NOT communicate/interact with the webpage where it is opened.

How am i going to validate the above code?

I wrote the code in the console, selected text from the webpage, pressed the run command and what i get is undefined.

I do not think the code is wrong, it is just that the firebug console seems not to communicate with the webpage where it is opened.
I am talking only for the console, no problem with css or html.

Thanks.

I tried your code, except for the function wrapper and saw the same
error. Then I removed "var" and it worked correctly. Not sure why this
is. Hopefully someone smarter than I can explain this.

Yes it worked on me also.

Me either cannot understand why removing the var makes it work.

// I assume you meant this statement to be on a separate line.

I'm unsure what makes you say this.

The code above is a function declaration. When you put it in the
console it evaluates to |undefined| because the expression has no
value.

I believe this is the correct result.

If you want to run the function you have to call it. For that you can
use:
GetSelectedText();
or
(function GetSelectedText () { if (window.getSelection)
{ var range = window.getSelection(); alert
(range.toString ()); } })();
