Firefox Extension: Get selected text
firefox, javascript, selection
Solution
Your problem is that `document.commandDispatcher.focusedWindow` is going to be pointing to a chrome window, where I suspect you actually want a content window. Try replacing that with `content.getSelection()`
Problem
I am working on a simple Firefox Extension and I want to get the selected text. I tried this: ``` var WordCount = { /* ... */ changeSelected: function() { var selectedText = this.getSelection(); var words = this.countWords(selectedText); this.changeStatus(words, " selected"); //alert(selectedText); }, getSelection: function(e) { var focused_window = document.commandDispatcher.focusedWindow; var sel_text = focused_window.getSelection(); return sel_text.toString(); } } window.addEventListener("select", function(e) { WordCount.changeSelected(); }, false); ``` The Problem is, that I dont get the selection with document.commandDispatcher.focusedWindow.getSelection() and I don't know why :(
