On my website I have a login and an article tag for editing.

my article code is in HTML5 witch is enough as my editor rule is HTML5:

HTML5: index.php line 212
    <article contentEditable="false"> >> Changes to true when in edit mode..
        <div>One row of text goes here.</div>
        <div>Row two's content goes here.</div>
    </article>

I want to be able to get the selected text via JS.

JS: js.php
format : (function(format){
    if (user = "{$ADMIN}"){
        selection   = getSelection();
        text        = selection.toString();
        switch(format){
            case "big":
                result = text.big();
            break;
            case "small":
                result = text.small();
            break;
            case "bold":
                result = text.bold();
            break;
            case "italics":
                result = text.italics();
            break;
            case "fixed":
                result = text.fixed();
            break;
            case "strike":
                result = text.strike();
            break;
            case "fontcolor":
                result = text.fontcolor();
            break;
            case "fontsize":
                result = text.fontsize();
            break;
            case "sub":
                result = text.sub();
            break;
            case "sup":
                result = text.sup();
            break;
            case "link":
                result = text.link();
            break;
        }
    }
}),

I can replace the text with the result but that will replace all of them I a=can do only the first but i want to do it to the selected...
