Instead of looping over each line get the current line number of your cursor and check only the character length of that line. See this SO answer for implementation details.

Then change your else statement to look like this:

else{
    var currLine = getLineNumber();
    if (lines[currLine].length >= $(this.attr('cols')) {
        return false; // prevent characters from appearing
    }
}
