jQuery Mobile Anchor Linking

in jQuery Mobile • 10 years ago

Hi All,
In the jQuery Mobile Documentation it says,

PLEASE NOTE: Since we are using the hash to track navigation history for all the Ajax 'pages', it's not currently possible to deep link to an anchor (index.html#foo) on a page in jQuery Mobile, because the framework will look for a 'page' with and ID of #foo instead of the native behavior of scrolling to the content with that ID.

on this page http://jquerymobile.com/demos/1.0a1/#docs/pages/docs-pages.html.

However this presents an issue because I have a client who had me build a site in jQuery Mobile however they have content already formatted using normal anchors with a page index at the top. (They're large pages).

Anyway, are there any really smart people out there that know if there's a way to disable jQuery Mobile for certain pages to allow for normal anchor linking?

Thanks,
Paul

See if this helps.

$(document).bind("mobileinit",function(){

$.mobile.ajaxLinksEnabled(false);

});

Hmm... This didn't seem to fix the issue.

For now I think there is no official way to create a native anchor behaviour. For the meantime something like this should work:

$('a.native-anchor').bind('click', function(ev) {
var target = $( $(this).attr('href') ).get(0).offsetTop;
$.mobile.silentScroll(target);
return false;
});

mallo's code solves my problem for anchor links on the same page, but only if inside $(document).ready(function(){}); inside $(document).bind("mobileinit", function() {}); it does not work. Also, unlike with normal anchors, the name attribute of the target is ignored, but it works with the id.

However, I found only half a solution to links on another page. The following code for a.other-page-link does only work with the "alert" and stops working if it is commented out:

<script type="text/javascript">
$(document).bind("mobileinit", function() {
//functions from below don't work here
});
$(document).ready(function(){
$('a.same-page-link').bind('click', function(ev) {
var target = $( $(this).attr('href') ).get(0).offsetTop;
//alert(target);
$.mobile.silentScroll(target);
return false;
});
$('a.other-page-link').bind('click', function(ev) {
var href = $(this).attr('href');
var parts = href.split("-");
var page = parts[0];
var id = "#"+parts[1];
$.mobile.changePage($(page));
var target = $( id ).get(0).offsetTop;
alert(target); // TODO: make work without alert ....
$.mobile.silentScroll(target);
return false;
});
});
</script>
<div data-role="page" id="home">
<div data-role="header" data-position="fixed">
<h1>Anchors</h1>
</div>
<div data-role="content">
<p><a href="#id1" class="same-page-link">click me to reach id on this page</a></p>
<p><a href="#page-id2" class="other-page-link" >click me to reach id on other page</a></p>
<p id="id1">i am the target of your dreams, don't call me by my name, just my id is what counts<br><br><br>
don't worry if you don't see the target of your dreams after the click, it is just a little further up the page, hidden by the header if its data-position is fixed</p>
<p>TODO: adjust scroll for fixed header
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<p>empty space so you can see the scroll</p>
</div>
</div>
<div data-role="page" id="page">
<div data-role="header" data-position="fixed">
<h1>other page</h1>
</div>
<div data-role="content">
<p id="id2">i am the target of your dreams, don't call me by my name, just my id is what counts<br><br><br>
don't worry if you don't see the target of your dreams after the click, it is just a little further up the page, hidden by the header if its data-position is fixed</p>
<p>TODO: adjust scroll for fixed header; make work without alert; fix back button;
</p>
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<p>empty space so you can see the scroll</p>
</div>
</div>

I am new to jQuery and jQueryMobile and would be grateful for any help with improving this code.

With the beta 1 version and binding both to vclick and click events everything works fine in Firefox, but on iOS the silentScroll does not happen after a changePage. Does someone have an idea why this is the case? Here is some sample code (could not attach it as file for some reason):

<!DOCTYPE html>

<html>
    <head>
         <meta name="viewport" content="width=device-width, initial-scale=1">

        <title>Anchors</title>

<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.js"></script>

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

     $('a.scroll').bind('click vclick', function(ev) {
          var target = $( $(this).attr('href') ).get(0).offsetTop;
          $.mobile.silentScroll(target);
          return false;
    });

    $('a.other-page-link').bind('click vclick', function(ev) {
        var href =     $(this).attr('href');
        var parts = href.split("-");
        var page = parts[0];
        var id = "#"+parts[1];
        $.mobile.changePage($(page));
        var target = $( id ).get(0).offsetTop;
        $.mobile.silentScroll(target);
        return false;
    });

});
</script>

    </head>

Re: Re: jQuery Mobile Anchor Linking

I made the silentScroll() after changePage() work also on iOS by calling it in 'pageshow':

    var scrollTarget = 0;

    $('a.other-page-link').bind('click vclick', function(ev) {
        var href =     $(this).attr('href');
        var parts = href.split("-");
        var page = parts[0];
        var id = "#"+parts[1];
        $.mobile.changePage($(page));
        scrollTarget = $( id ).get(0).offsetTop;
        return false;
    });

   $('div').live('pageshow',function(event, ui){
        if (scrollTarget != 0) {
            $.mobile.silentScroll(scrollTarget);
            scrollTarget = 0;
        }
    });

This worked for me (on desktop and iOS Safari):

$('.container a[href^=#]').bind('click vclick', function (ev) {
location.hash = $(this).attr('href');
return false;
});

Re: jQuery Mobile Anchor Linking

Mikhael,

I think your suggestion works incase you are having a fairly simple article page as such, if you use multipage template the above method with silent scroll is the way to go . Especially if you are heavy on changepage events ect.

Re: jQuery Mobile Anchor Linking

I was able to get anchor tags by using this:

<script type="text/javascript">
$(document).ready(function() {
$('a.anchor').click(function(e) {
obj = e.target;
str = String(obj);
var lett = str.charAt( str.length-1 );
document.getElementById(lett).scrollIntoView();
e.preventDefault();
});
});
</script>

I was had an alphabetically list - and I gave them as anchor tags with the class "anchor"

<a href="#A" class="anchor">A</a>
<a href="#B" class="anchor">B</a>
<a href="#C" class="anchor">C</a>

Then I had divs on the page ID'd with each letter...

<div id="A">My Div for A</div>
<div id="B">My Div for B</div>
<div id="C">My Div for C</div>

It works perfect! So you can essentially just use it with your href having a # sign with then your div's id you want it to jump too....

Try to use $(this).data('href'); instead of $(this).attr('href'); . Hope this helps you.

Re: jQuery Mobile Anchor Linking

8 years ago

Hello, my name is John and I am currently developing a mobile web app. I am having an issue with the internal multipage structure. The issue is on my homepage I have 4 anchor links (internal links) and I have had success with 3 of the anchor links working correctly and displaying the page correctly. The issue I am having is the 4th anchor link when clicked displays a blank (all white) page. I have even tried taking all the excess code away with just the basic div structure with a couple words inside the div data-role="content" section. I have checked everything time and time again. Is there a limitation to the amount of internal pages or internal links? Any help would be greatly appreciated. Also, if anyone is willing to help I will post the code, its just lengthy.

Re: jQuery Mobile Anchor Linking

I have been struggling with this problem, too...

I read and tried all the possible suggestions on this thread, but none of them seemed to really solve my problem.

I also tried this workaround: instead of using anchors, I tried to use $.mobile.silentScroll(100); to scroll page to a definite number of pixels and to emulate the anchor feature.

Unfortunately, this works only partially. In fact, when I put the silentScroll inside the $(document).bind("mobileinit", function() { }); it does scroll page, but, when all pictures and text are fully loaded, the page goes to the top again :-\

Another workaround is to set a Timeout to the silentScroll function, in order to wait some seconds, hoping the page will be fully loaded, before operating the scroll.

It's not a good solution, because different pages may take different time to load, also depending on internet bandwith, so it becomes difficult to predict page loading time.

I give some example code below:

$(document).bind("mobileinit", function(){

/* this one scrolls page to top on button click and works good */

$('#uptotop').live('click', function() {

$('body, html').animate({scrollTop: '0px'}, 1000, function(){ $('body').clearQueue(); });

/* below the (in)famous silentscroll with timeout */

setTimeout(function(){$.mobile.silentScroll(800);}, 4000);

});

</script>

Re: jQuery Mobile Anchor Linking

Hello,

getting back to this question as I solved some issues recently.

Using the $.extend function below, I was able to totally disable jquery mobile navigation behaviour,

so that I could use ordinary html anchors to make page scroll to a specific html anchor.

This works fine inside the single page, so I don't need silentscroll anymore.

My problem is when I need to link to a specific anchor from a different page of the same website.

So, to explain it better, if I have a button or link to www.mywebsite.com/mywebpage.php?item=1234#myanchor inside the same mywebpage.php it works and scrolls page to #myanchor id.

But if I put a link or button at www.mywebsite.com/anotherpage.php pointing to www.mywebsite.com/mywebpage.php?item=1234#myanchor it brings me on top of page, without scrolling to #myanchor id.

Note that both mywebpage.php and anotherpage.php have the same $extend function enabled (which means jquery mobile ajax navigation disabled).

Thank you so much, hope I helped someone to solve this issue, at least partially.

$(document).bind("mobileinit", "#mypage", function(){
$.extend($.mobile, {
hashListeningEnabled: false,
pushStateEnabled: false,
ajaxEnabled: false,
linkBindingEnabled: false
});
});

Re: jQuery Mobile Anchor Linking

7 years ago

could you please elaborate some more about the difference between mikhail.nz's solution (based on location.hash) and mallo's solution (based on silentScroll)

mikhail.nz's solution:

$('.container a[href^=#]').bind('click vclick', function (ev) {
location.hash = $(this).attr('href');
return false;
});

mallo's solution:

$('a.native-anchor').bind('click', function(ev) {
var target = $( $(this).attr('href') ).get(0).offsetTop;
$.mobile.silentScroll(target);
return false;
});

Reviving this old thread because I didn't find any of the replies useful.

This simple delay allows the anchor hash links to work like traditional links with jquery mobile:

$(document).ready(function(){
var anchor_id = window.location.hash;
if(anchor_id != ""){
var new_position = $(anchor_id).offset();
setTimeout(function(){window.scrollTo(new_position.left,new_position.top)}, 500);
}
})

Re: Re: jQuery Mobile Anchor Linking

The setTimeout worked for me. I set it to 100 rather than 500 as you could really see the page move. I tried 50 but it didn't work for that.

watusiware

Re: jQuery Mobile Anchor Linking

6 years ago

$(document).ready() is fired only once, though - when the very first page is loaded. You would need to also disable Ajax navigation, and at that point you have to ask yourself why you are using jQuery Mobile at all.

cmusicfan

Re: jQuery Mobile Anchor Linking

6 years ago

and at that point you have to ask yourself why you are using jQuery Mobile at all.

The built-in AJAX aspect of jquery mobile is not the sole reason to use it.

Besides that, the OP says

Anyway, are there any really smart people out there that know if there's a way to disable jQuery Mobile for certain pages to allow for normal anchor linking?

My answer works with or without jquery mobile.

Yes, I can absolutely confirm this, been looking around a while and finally found this solution, thanks Mark!

Re: jQuery Mobile Anchor Linking

Adding data-ajax="false" to an anchor makes it work normally. The page will scroll to target hash without changing pages.

ccouper

Re: jQuery Mobile Anchor Linking

6 years ago

data-ajax="false" is true works for all but Windows phone 8/8.1 when running on Cordova. For that setup you still need Mallo's approach above.

Nothing else works.

watusiware

Re: jQuery Mobile Anchor Linking

6 years ago

Omar, I'm surprised that works, as this has been a long-standing problem, and it is always been understood (or so I thought) that the only solution was to use some JS code to select the element and scroll to it.

I wonder if there was some change in some JQM version or some change in browser behavior that made this stop working?

I'll do some experiments. t'd be very odd (though not beyond possibility) that this "feature" went this long without being noticed! (At least by me.) But I avoid IDs.

We do have some pop-up help in apps that I work on that uses the "find the element and scroll to it" technique. That's still needed in our case, though, because we use iScroll to scroll the help inside the popup. Since I always use iScroll, I always need to use some code to scroll, and so I haven't given this problem much thought.
