我的菜单无法与“ StickyPanel”一起使用

Question

I'm kinda new to creating websites, so bear with me.

I just started a new project and I wanted a menu that follows when you scroll, and then stops when it reaches the top of the page. I found a really cool JavaScript plugin called "StickyPanel" ( https://code.google.com/p/sticky-panel/ ), but it won't cooperate. Apparently there are no instructions and I can't find any useful info else where.

The code is very simple:

<script src="js/jquery.js"></script>
<script src="js/jquery.stickyPanel.min.js"></script>

<!-----Sticky Panel------>

<script type="text/javascript">
        $().ready(function () {

            var stickyPanelOptions = {
                afterDetachCSSClass: "",
                savePanelSpace: true
            };
            $("header").stickyPanel(stickyPanelOptions);
        });
    </script>

    <script>
        $(document).ready(function(){
            $(".nav-button").click(function () {
            $(".nav-button,.menu").toggleClass("open");
            });    
        });
    </script>

<!-----Sticky Panel------>

Then I made a div class called "header" and then styled the header-menu. I can't get the JavaScript to do anything with my header. What am I doing wrong?

Answer 1

        $("header").stickyPanel(stickyPanelOptions);

You ask Jquery for the elemet header You need to ask jquery the class header =>

        $(".header").stickyPanel(stickyPanelOptions);

Read about slectors its usefull!

        <header> is a html5 element, support by almost all browser but dont forget display: block in css!

Answer 2

使用$(".header")而不是$("header")选择div

Answer 3

There is another way to it if you don't want to use this plugin. found this code somewhere on internet. it uses position:fixed css style, simple js

javascript

<script type="text/javascript">
    window.onload = function () { 
    $(window).scroll(function () {
    var e = $("#StickyPanel"); 
    if (document.documentElement.scrollTop >= 602 || window.pageYOffset >= 602) { 
    if ($.browser.msie && $.browser.version == "6.0") 
    { 
    e.css("top", document.documentElement.scrollTop + 15 + "px") } 
    else { 
    e.css({ position: "fixed", top: "1%" }) } } 
    else if (document.documentElement.scrollTop < 602 || window.pageYOffset < 602) 
    {            
     e.css({ position: "absolute", top: "91%" }) } }) }
     </script>

css

#search
{
  position: absolute;
  top: 91%;
 }

just change the values

602

according to your needs

Hope it helps.
