Get text selection and properties

@All – let's do an example of a selection with a screenshot (always best to illustrate the problem):

Simple example, some characters selected with different formatting (in this case the fillColor property):

In total 5 textStyleRanges in the text frame.
Two textStyleRanges in the selection of the same frame below.

If you want to ask for the fillColor used in the 2 textStyleRanges of the selection, you can do it like that:

var mySelection = app.selection[0];
var myTextStyleRanges = mySelection.texts[0].textStyleRanges.everyItem().getElements();
for(var n=0;n<myTextStyleRanges.length;n++){
    $.writeln(myTextStyleRanges.fillColor.name);
    };

The result of my example as written to the JavaScript console of the ESTK (ExtendScript Toolkit):

"C=75 M=5 Y=100 K=0" for the first textStyleRange in the selection

"C=100 M=0 Y=0 K=0" for the second textStyleRange in the selection

But like the example with asking for paragraphs in a selection, the same goes for textStyleRanges:
You are asking for the whole object, you'll get the whole object.

And if you would ask for the "contents" (the not formatted string representation of a texts object), in the case of textStyleRanges in my example like that

myTextStyleRanges.texts[0].contents

you would get the following results:

"ij" for the first textStyleRange in the selection

"klmn" for the second textStyleRange in the selection

However, the contents of the selection in my example would be:

"ijkl"
