I use JQuery with the Ace Editor, and I found the following code worked really nicely for me. PS: My Code Editor Window is in an Iframe:

$('#modelFrame').mouseover(function() {
    try {
        $(this).get(0).contentWindow.editor.focus();
    } catch (doNothing) {
        ;;
    }
});

To focus to the end:

Here's an excerpt from my code that sets the focus on an Ace edit session in a jQuery UI tab:

    $('#tabs_div').tabs(
        {
            select : function(event, ui) {
                        var tabName = ui.panel.id;
                        var doc = docs.get(tabName);  // look up the EditSession
                        var session = env.split.setSession(doc);
                        session.name = tabName;
                        env.editor.focus();
            }

Answer 4

editor.focus(); //To focus the ace editor
var n = editor.getSession().getValue().split("\n").length; // To count total no. of lines
editor.gotoLine(n); //Go to end of document

Answer 5

Nice solution, but I wanted to go to the end of the last line not the beginning of the last line.

//To focus the ace editor
editor.focus();
session = editor.getSession();
//Get the number of lines
count = session.getLength();
//Go to end of the last line
editor.gotoLine(count, session.getLine(count-1).length);
