How to convert text selection into Hyperlink?

Something like the following should work, run the code with a text selection and it should create the hyperlink on it. Change the app.selection[0] to the object of the text that you might have in your actual code

var source = app.documents[0].hyperlinkTextSources.add(app.selection[0])
var dest = app.documents[0].hyperlinkURLDestinations.add("http://"+ app.selection[0].contents)
app.documents[0].hyperlinks.add(source,dest, {name:app.selection[0].contents})
