So this post might get lengthy but I'm stuck with iScroll. What I'm doing is populating my list with articles and when one gets clicked, I'm sliding in a div over the list to display the article. That part works but what doesn't is when I scroll through the article and get to the end, it keeps scrolling the list with articles. You can have a look here (the site is in russian but click on an article and scroll all the way to the bottom). Here's my entire code:

<head>
    <style>
        body{
            padding: 0;
            margin: 0;
            border: 0;
        }
        #header{
            position:fixed;
            top:0;
            left:0;
            height:100px;
            width: 100%;
            background-color: black;
        }
        header{
            position: absolute;
            z-index: 2;
            top: 0; left: 0;
            width: 100%;
            height: 50px;
        }
        #wrapper{
            position: absolute;
            z-index: 1;
            width: 100%;
            top: 52px;
            left: 0;
            overflow: auto;
        }
        #container{
            position:fixed;
            top:0;
            right:-100%;
            width:100%;
            height:100%;
            z-index: 10;
            background-color: red;
            overflow: auto;
        }
        #content{
            margin:100px 10px 0px 10px;
        }
    </style>
</head>
<body>
    <header>Main News</header>
    <div id="wrapper">
        <ul id="daily"></ul>
        <ul id="exclusive"></ul>
        <ul id="must"></ul>
        <ul id="main"></ul>
        <ul id="ukr"></ul>
        <ul id="nba"></ul>
        <ul id="euro"></ul>
    </div>
    <div id="container">
        <div id="wrapper2">
            <div id="header">
                <button onclick="hide();">Back</button>
            </div>
            <div id="content"></div>
        </div>
    </div>
    <script src="js/zepto.js"></script>
    <script>
        //AJAX requests to fill the li's...
        function sayhi(url){
            $('#container').animate({
                right:'0',
            }, 200, 'linear');
            $.ajax({
                url: serviceURL + "getnewstext.php",
                data: {link: url},
                success: function(content){
                    $('#content').append(content);
                }
            });
        }
        function hide(){
            $('#container').animate({
                right:'-100%'
            }, 200, 'linear');
            $('#content').empty();
        }
    </script>
    <script src="js/iscroll-lite.js"></script>
    <script>
        var myScroll;
        function scroll () {
            myScroll = new iScroll('wrapper2', {hScroll: false, vScrollbar: false, bounce: false});
            myScroll2 = new iScroll('wrapper', {hScroll: false, vScrollbar: false});
        }
        document.addEventListener('DOMContentLoaded', scroll, false);
    </script>
</body>

Is there a way to scroll on the div container, or content, or wrapper2 without scrolling the wrapper div with the list of articles? Maybe I'm not using iScroll correctly? The same problem happens on Android and iPhone.

EDIT 1:

I set the wrapper position to fixed. Now the div container is the only one scrolling but the list of articles isn't scrolling...I added another iScroll to the wrapper but it's not working. Any advice here?

EDIT 2:

So I dropped iScroll all together and trying with CSS instead. To my onclick events I added:

$('body').css('overflow', 'hidden');

And when the close button is clicked I changed the overflow to auto. Now this stops the body from scrolling in a browser but not on mobile!!! How can I make it do the same thing on mobile???

I finally got it to work. What I needed to do is add another div inside the wrapper div. I'll share the code so hopefully it helps someone else Here's what the new code looks like:

<body>
    <!--Added scroller div(without iScroll it works also...just make two divs so the body isn't scrolled but the second div is scrolled-->
    <div id="wrapper">
        <div class="scroller">
            <header>Main News</header>
            <ul id="daily"></ul>
            <ul id="exclusive"></ul>
            <ul id="must"></ul>
            <ul id="main"></ul>
            <ul id="ukr"></ul>
            <ul id="nba"></ul>
            <ul id="euro"></ul>
        </div>
    </div>
    <div id="container">
        <div class="scroller">
            <div id="header">
                <button onclick="hide();">Back</button>
            </div>
            <div id="content"></div>
        </div>
    </div>
<script>
        $('body').on('touchmove', function(e){
            e.preventDefault();
        });
//prevents native scrolling so only iScroll is doing the scrolling
//after the AJAX call to get the content, declare your iScroll variable
var myScroll;
            myScroll = new iScroll('wrapper');
            setTimeout (function(){
                myScroll.refresh();
            }, 2000);

    //set time out to give the page a little time to load the content and refresh your iScroll variable so it takes in the entire content of the wrapper div

var myScroll1;
        myScroll1 = new iScroll('container');
//I defined my second iScroll variable here so I can destroy it in the next part...

//function sayhi(url) stays the same but in success of AJAX looks like this:
success: function(content){
                    $('#content').append(content);
                    myScroll1.destroy();
                    myScroll1 = null;
                    myScroll1 = new iScroll('container');
                    setTimeout (function(){
                        myScroll1.refresh();
                    }, 2000);
                }
//when the div slides on the screen and content gets loaded, destroy your second iScroll
//variable, set it to null and define it all over again so it takes in the entire content

And that's it. Works perfectly now with two divs which need to use iScroll on the same page. Hope the explanation is clear enough and helps someone!!!
