Redirect to a div on a different page with smooth scrolling?

问题

Question Background:

I have a 2 page website. Both pages use the same masterlayout.cshtml page which features a Navbar. Within the Navbar is a number of links which scroll down to the relevant divs on page one based on their ID's.

The Issue:

When I access the second page I can no longer redirect to the specified divs from the Navbar links on the first page. This makes sense as the focus is no longer on the first page, but how do I get around this issue?

Code:

Here is the Navbar code with the div id's set, note the data-id attributes specifying which div to scroll to:

        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav">
                <li><a href="#" class="scroll-link" data-id="Welcome">Welcome</a></li>
                <li><a href="#" class="scroll-link" data-id="features">Club</a></li>
                <li><a href="#" class="scroll-link" data-id="About">About Us</a></li>
                <li><a href="#" class="scroll-link" data-id="Location">Location</a></li>
                <li><a href='@Url.Action("FutureEvents", "Events", new { pageNo = 1 })'>Events</a></li>
            </ul>
        </div> 

Example of a div that is scrolled to:

        <div id="Welcome">
             //HTML
        </div>

The JQuery used to Scroll to the relevant div:

        function scrollToID(id, speed) {
          var offSet = 70;
          var obj = $(id).offset();
          var targetOffset = $(id).offset().top - offSet;
          $('html,body').animate({ scrollTop: targetOffset }, speed);
        }

If anyone can help with coming up with a viable solution to being able to call these id's from a different page that would be great.

回答1:

This can be done with cookies. Setting a cookie with id you want to scroll, and then, when the new page is loaded, read the cookie and scroll to defined id. I used the very popular plugin jquery-cookie.

Here is the JavaScript code:

$(document).ready(function () {
    // Read the cookie and if it's defined scroll to id
    var scroll = $.cookie('scroll');
    if(scroll){
        scrollToID(scroll, 1000);
        $.removeCookie('scroll');
    }

    // Handle event onclick, setting the cookie when the href != #
    $('.nav a').click(function (e) {
        e.preventDefault();
        var id = $(this).data('id');
        var href = $(this).attr('href');
        if(href === '#'){
            scrollToID(id, 1000);
        }else{
            $.cookie('scroll', id);
            window.location.href = href;
        }
    });

    // scrollToID function
    function scrollToID(id, speed) {
        var offSet = 70;
        var obj = $('#' + id);
        if(obj.length){
          var offs = obj.offset();
          var targetOffset = offs.top - offSet;
          $('html,body').animate({ scrollTop: targetOffset }, speed);
        }
    }
});

Here I have prepared a minimal example with this working:

Note: Click on Events to nav to the other page.

You can track hash of page url and scroll page to particular div

<a href="#Welcome" class="scroll-link">Welcome</a>
<a href="your_page_url#Welcome" class="other-page">Welcome</a> <!-- link to other page scroll div -->

Jquery

$(document).ready(function(){
    var speed = 1000;

    // check for hash and if div exist... scroll to div
    var hash = window.location.hash;
    if($(hash).length) scrollToID(hash, speed); 

    // scroll to div on nav click
    $('.scroll-link').click(function (e) {
        e.preventDefault();
        var id = $(this).attr('href');
        if($(id ).length) scrollToID(id, speed);
    });
})

function scrollToID(id, speed) {
    var offSet = 70;
    var obj = $(id).offset();
    var targetOffset = obj.top - offSet;
    $('html,body').animate({ scrollTop: targetOffset }, speed);
}

You can try something like this. I have changed data-id to id. You can use javascript.

<ul class="nav navbar-nav">
    <li><a href="#" class="scroll-link" onclick="scrollme(this.id)" id="Welcome">Welcome</a></li>
    <li><a href="#" class="scroll-link" onclick="scrollme(this.id)" id="features">Club</a></li>
    <li><a href="#" class="scroll-link" onclick="scrollme(this.id)" id="About">About Us</a></li>
    <li><a href="#" class="scroll-link" onclick="scrollme(this.id)" id="Location">Location</a></li>
    <li><a href='#' onclick="scrollme(this.id)" id="Event">Events</a></li>
</ul>

Javascript to scroll

function scrollme(id)
{
     var scrollElem = scrollableElement('html', 'body');
     var targetOffset = $(id).offset().top;
      $(scrollElem).animate({scrollTop: targetOffset-100}, 1000, function() {

          });
}
function scrollableElement(els)
{
    for (var i = 0, argLength = arguments.length; i <argLength; i++) {
      var el = arguments[i],
          $scrollElement = $(el);
      if ($scrollElement.scrollTop()> 0) {
        return el;
      } else {
        $scrollElement.scrollTop(1);
        var isScrollable = $scrollElement.scrollTop()> 0;
        $scrollElement.scrollTop(0);
        if (isScrollable) {
          return el;
        }
      }
    }
    return [];
}

How do you redirect to another page, using href value?

If so, also add in data-id for this <a> tag too.

So when you click on Events link, it will go to another html page and you want to scroll to Events div, right?

Then using sessionStorage, you can store and get back the page id, then scroll to its specific div.

Add below script and let's see.

JQUERY

$(document).ready(function(){

    // get sessionStorage for page id
    var get_id = sessionStorage.getItem('pg_id');

    // check page id, then scroll to its div
    if(get_id)
        scrollToID(get_id, 300);

    // click event to scroll to div
    $('.nav li a').on('click', function(){
        var id = '#'+$(this).data('id');
        sessionStorage.setItem('pg_id', id);
        scrollToID(id, 300);
    }); 

});
function scrollToID(id, speed) {
    var offSet = 70;
    var obj = $(id).offset();
    var targetOffset = $(id).offset().top - offSet;
    $('html,body').animate({ scrollTop: targetOffset }, speed);
}

HTML (My sample)

<ul class="nav navbar-nav">
    <li><a href="#" class="scroll-link" data-id="Welcome">Welcome</a></li>
    <li><a href="#" class="scroll-link" data-id="features">Club</a></li>
    <li><a href="#" class="scroll-link" data-id="About">About Us</a></li>
    <li><a href="#" class="scroll-link" data-id="Location">Location</a></li>
    <li><a href='page2.html' data-id="Event">Events</a></li>
    <!-- use your script to redirect to another page, but add "data-id" -->
</ul>

回答5:

If I understand what you mean. Than you can just do this what an iFrame. In the Navbar for each tab just put a href='#welcome' or href='#features' and than give the iFrame for welcome a ID of welcome. When you click on the tab for welcome. You will be send to the iFrame with the welcome content. For features do the same and all following tabs.

Simplest way is to create another nav bar for other page from where you want to redirect your end users

try this:

create a file first.php or first.html

<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<style>
.t{
    min-height: 200px;
    border: 2px solid;
}
</style>
  <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav">
                <li><a href="#" class="scroll-link" data-id="Welcome">Welcome</a></li>
                <li><a href="#" class="scroll-link" data-id="features">Club</a></li>
                <li><a href="#" class="scroll-link" data-id="About">About Us</a></li>
                <li><a href="#" class="scroll-link" data-id="Location">Location</a></li>
                <li><a href='@Url.Action("FutureEvents", "Events", new { pageNo = 1 })'>Events</a></li>
            </ul>
        </div> 
<div id = 'Welcome' class="t">
</div>
<div id = 'features' class="t">
</div>
<div  id = 'About'class="t">
</div>
<div  id = 'Location' class="t">
</div>
<div id ='div_101' class="t">
scroll upto here
</div>
<script>

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}


$(document).ready(function(){   
    var param_scroll = getParameterByName('id');
    if(param_scroll){
        $('html, body').animate({
            scrollTop: $("#"+param_scroll).offset().top
        }, 3000);   
    }
});


</script>

Then second file with different nav-bar

<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav">
                <li><a href="first_page.php?id=Welcome" class="scroll-link" data-id="Welcome">Welcome</a></li>
                <li><a href="first_page.php?id=features" class="scroll-link" data-id="features">Club</a></li>
                <li><a href="first_page.php?id=About" class="scroll-link" data-id="About">About Us</a></li>
                <li><a href="first_page.php?id=Location" class="scroll-link" data-id="Location">Location</a></li>
                <li><a href='@Url.Action("FutureEvents", "Events", new { pageNo = 1 })'>Events</a></li>
            </ul>
        </div>

I guess you may use $.cookie every time you scroll on the first page.

For Example :

$(document).ready(function()
{
    $('.scroll-link').on("click",function()
    {
       $.cookie('page',$(this).attr('data-id')); 
    });
    if($.cookie('page') != null || $.cookie('page') != "")
    {
        scrollToID($.cookie('page'), 1000);
    }
})

You can send the ID of the div, that you want to scroll to, to the second page through a URL query string and write a script (in page 2) to read the URL and scroll to the specified div. Piece of cake.
