在Magento中使用offset（）。top吗？

Question

Have following HTML code 具有以下HTML代码

<head>
    <title>onepage scroll</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1, minimum-scale=1 user-scalable=no"/>
    <link href="css/test.css" rel="stylesheet" type="text/css"/>  
</head>

<body>

    <section class="container">
        <nav class="test-nav">
            <a href="#" id="sc-head">Home</a> 
            <a href="#section_1" id="c1">Section 1</a>

            <div class="sc-content">
                <p>onepage scroll top content </p>      
            </div>
        </section>

        <section class="sc c1">
            <div class="sc-content">
                <p>Content 1</p>
            </div>
        </section>

        <section class="sc c2">
            <div class="sc-content">

        </section>


        <section class="sc c6">

    </section>

    <script type="text/javascript"  src="js/jquery.min.js"></script>
    <script type="text/javascript"  src="js/scroll.js"></script>
    <script type="text/javascript">
        jQuery('.test-nav').scroll({'scrollSpeed' : 1000});

Now scroll.js 现在滚动

(function($, window, document, undefined) { 
    $.fn.op_scroll = function( options ) {
        $(this).addClass('op-scroller');
        var settings   = $.extend({'scrollSpeed '  : 500}, options);
        var optionLocs = new Array();
        var lastScrollTop = 0;

        $(window).load(function() {
            if( window.location.hash == "")
                setTimeout(function() { window.scrollTo(0, 1) }, 100);
            else
                $("a[href='"+window.location.hash+"']").trigger('click');
        });

        return $(scroller_head + ' a').each( function(index) {

            if ( settings.scrollSpeed ) {
                var scrollSpeed = settings.scrollSpeed
            }

            var element = $(this);
            var id = element.attr("id");
            optionLocs.push(Array($("."+id).position().top-menuHeight, $("."+id).height()+$("."+id).position().top, id));

            var stickyTop = $('.op-scroller').offset().top;   console.log(stickyTop);

            };
            stickyMenu("");
            $(window).scroll(function() {
                var st = $(this).scrollTop();
                if (st > lastScrollTop) {
                    direction = "down";

                stickyMenu(direction);

                if($(window).scrollTop() + $(window).height() == $(document).height()) {

                var goTo =  $('.'+ id).offset().top -selectorHeight;

                // alert(hash);
                window.location.hash = hash;
                // window.location.hash = $(this).html().charAt(0).toUpperCase() + $(this).html().slice(1);
            }); 
        });
    }

})(jQuery, window, document);

I am trying to working one page scroll with given js. 我正在尝试使用给定的js进行一页滚动。 It works as expected when i use it as separate example. 当我将其用作单独的示例时，它按预期工作。

Having issue when integrating this js with Magento in following line 在下一行中将此js与Magento集成时出现问题

var stickyTop = $('.op-scroller').offset().top;   
console.log(stickyTop); // It gives each 'a' offset top position instead of first one(<a href="#" id="sc-head">Home</a>).

I suspect with prototype.js library. 我怀疑与prototype.js库。 Kindly advice 好心的建议

Since Magento used Prototype . 由于Magento使用了Prototype 。 There's probably happen a conflict here. 这里可能发生冲突。 So try to wrap your jQuery code like this: 因此，尝试像这样包装您的jQuery代码：

jQuery(document).ready(function( $ ) {
     // Your jQuery code using $ here
});
