I'm currently working on a website where the navigation bar links would seamlessly lead to another page with fading transitions without loading.
When the links are clicked, the div#page block, which has the main page content and the footer, would fade out, empty itself, and fade back in with the content of the href of the clicked link. However, my current code, seen below, placing the html of the entire page (including the head contents) on div#page instead of just the inner HTML of div#page.
$("#header .menu a, #header .logo").click(function() {
var href = $(this).attr("href");
var title = $(this).attr("title");
history.pushState(null, title, href);
$("#page").fadeOut("slow", function() {
$("#page").delay(1000).empty();
});
$("#page").load(href + "#page", function() {
$("#page").fadeIn();
});
return false;
});
From the docs
The .load() method, unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.
So try adding a white-space like so
$("#page").load(href + " #page", function() { //White space before #page
$("#page").fadeIn();
});
PS: I have not tested this code.
Two options:
The recommended way would be to create an API that would return the
inner HTML only.
Parse the response like so (example):
var $dom = $('<div />');
$dom.html(response);
var $content = $dom.find('#id'); // #id is your inner content id
And now you should be able to insert the inner content using $content.html().

I'm evaluating Featherlight lightbox and I'm not able to implement code that satisfies my use case. I need a lightbox that will be used as a report viewer which displays dynamically created content assigned to a JavaScript variable. The value of the string is a valid HMTL5 page.
I've looked at the iframe example, but it depends upon a static iframe being in the DOM. That's not what I need.
I've reviewed this GitHub issue and this jsfiddle and I'm not able to successfully modify the fiddle to display a string.
This is an example of the string I would like to display:
var s = '<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Title of the document</title></head><body><p>Content of the document......</p></body></html>';
Is this possible and if so how?
I expect that $.featherlight() will be called manually in response to a button click.
The solution I came up with was to modify the Featherlight source code in 2 places as indicated in this block of code (currently around line 383).
iframe: {
process: function(url) {
var deferred = new $.Deferred();
var $content = $('<iframe/>')
.hide()
.attr('src', url)
.attr('id', this.namespace + '-id') // [KT] 10/31/2016
.css(structure(this, 'iframe'))
.on('load', function() {if ($content.show()) {deferred.resolve($content.show()) } else {deferred.resolve($content)} ; }) // [KT] 10/31/2016
// We can't move an <iframe> and avoid reloading it,
// so let's put it in place ourselves right now:
.appendTo(this.$instance.find('.' + this.namespace + '-content'));
return deferred.promise();
}
},
The id attribute is added to the iframe so content can be added by JavaScript, like this:
var s = '<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Title of the document</title></head><body><p>Content of the document......</p></body></html>';
var oIframe = document.getElementById('featherlight-id'); // Featherlight's iframe
var iframeDoc = (oIframe.contentDocument || oIframe.contentWindow.document);
iframeDoc.open();
iframeDoc.write(s);
iframeDoc.close();
This then works:
$.featherlight({iframe: 'about:blank', iframeWidth: '96%' });
The 2nd modification is required so that the url 'about:blank' doesn't raise an error.
I also modified the css so as to get the scroll bars to work as needed.
Edit: the issue with Featherlight not opening an iframe when the url is abount:blank has been fixed as of version 1.5.1.
Edit 2: Using v1.5.1, this works without having to make a modification to Featherlight to add an id to to the iframe:
var s = '<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Title of the document</title></head><body><p>Content of the document......</p></body></html>';
$.featherlight({iframe: 'about:blank'});
var $iframe = $('.featherlight iframe');
$iframe.ready(function () {
$iframe.contents().find("body").append(s);
});
The accepted SO answer was used for this solution.
I have the following initiation in my JavaScript; I’m always using the code shown in github by the way. The full code can be seen here
var
/* Application Specific Variables */
contentSelector = '.tab-content,.page-content,article:first,.article:first,.post:first',
$content = $(contentSelector).filter(':first'),
contentNode = $content.get(0),
$menu = $('#menu,#nav-sub,.nav,.nav-sub:first').filter(':first'),
activeClass = 'active selected current youarehere open',
activeSelector = '.active,.selected,.current,.youarehere, .open',
menuChildrenSelector = '> li,> ul > li',
/* Application Generic Variables */
$body = $(document.body),
rootUrl = History.getRootUrl(),
scrollOptions = {
duration: 800,
easing:'swing'
};
The problem lies in :
contentSelector = '.tab-content,.page-content,article:first,.article:first,.post:first',
and in:
$menu = $('#menu,#nav-sub,.nav,.nav-sub:first').filter(':first'),
When the menu clicked in .nav, has to change the .page-content.
When the menu is clicked in .nav-sub, the content has to be replaced in .tab-content
The problem is, both menu's change .page-content, instead of just either tab-content or page-content.
Any idea how to change this?
Fix your content select
Change from
contentSelector = '.tab-content,.page-content,article:first,.article:first,.post:first'
TO
contentSelector = '.tab-content, .page-content, .article:first, .post:first'
History.js isn't replacing the wrong content; ajaxify-html5.js (the script you are using) is doing exactly as it was designed:
If the user clicks on an internal link (and the link does not have the no-ajaxy class), then the script intercepts the click, stops the browser from loading the page, and initiates an Ajax request for the page.
Note that this includes all internal links on the page, not just ones in the menu.
When the Ajax request is complete, the script replaces the content on the current page with the content from the response (and does some other clever things like set the activeClass on the right menu item, update the page title and run scripts from the response).
The script uses the first element found with contentSelector as the "content" node. This does not depend on which link the user clicked on.
If you want to "ajaxify" only menu links, you can change (line 95):
$body.ajaxify();
to call .ajaxify() on your menu element instead.
If you want to update a different element with the new content, you can change (line 145):
$content.html(contentHtml).ajaxify().css('opacity',100).show(); /* you could fade in here if you'd like */
to update another element instead.
I have an html file that I want to be loaded from various pages into a dijit.contentpane. The content loads fine (I just set the href of the contentpane), but the problem is that javascript within the html file specified by href doesn't seem to be executed at a consistent time.
The final goal of this is to load an html file into a contentpane at an anchor point in the file (i.e. if you typed in index.html#tag in order to jump to a certain part of the file). I've tried a few different methods and can't seem to get anything to work.
What I've tried:
1.
(refering to the href of the dijit.contentpane)
href="page.htm#anchor"
2.
(again, refering to the href of the dijit.contentpane -- didn't really expect this to work, but decided to try anyways)
href="#anchor"
3. (with this last try inside the html specified by href)
<script type="text/javascript">
setTimeout("go_to_anchor();", 2000);
function go_to_anchor()
{
location.href = "#anchor";
}
</script>
This last try was the closest to working of all of them. After 2 seconds (I put the delay there to see if something in the dijit code was possibly loading at the same time as my javascript), I could see the browser briefly jump to the correct place in the html page, but then immediately go back to the top of the page.
Dojo uses hashes in the URL to allow bookmarking of pages loaded through ajax calls.
This is done through the dojo.hash api.
So... I think the best thing you can do is use it to trigger a callback that you write inside your main page.
For scrolling to a given position in your loaded contents, you can then use node.scrollIntoView().
For example, say you have a page with a ContentPane named "mainPane" in which you load an html fragment called "fragment.html", and your fragment contains 2 anchors like this :
-fragment.html :
Anchor 1
<p>some very long contents...</p>
Anchor 2
<p>some very long contents...</p>
Now say you have 2 buttons in the main page (named btn1 and btn2), which will be used to load your fragment and navigate to the proper anchor. You can then wire that up with the following javascript, in your main page :
<script type="text/javascript">
require(['dojo/on',
'dojo/hash',
'dojo/_base/connect',
'dijit/layout/BorderContainer',
'dijit/layout/ContentPane',
'dijit/form/Button'],
function(on, hash, connect){
dojo.ready(function(){
var contentPane = dijit.byId('mainPane');
var btn1 = dijit.byId('btn1');
var btn2 = dijit.byId('btn2');
btn1.on("Click", function(e){
if (!(contentPane.get('href') == 'fragment.html')) {
contentPane.set("href", "fragment.html");
}
hash("anchor1");
});
btn2.on("Click", function(e){
if (!(contentPane.get('href') == 'fragment.html')) {
contentPane.set("href", "fragment.html");
}
hash("anchor2");
});
// In case we have a hash in the URL on the first page load, load the fragment so we can navigate to the anchor.
hash() && contentPane.set("href", "fragment.html");
// This callback is what will perform the actual scroll to the anchor
var callback = function(){
var anchor = Array.pop(dojo.query('a[href="#' + hash() + '"]'));
anchor && anchor.scrollIntoView();
};
contentPane.on("DownloadEnd", function(e){
console.debug("fragment loaded");
// Call the callback the first time the fragment loads then subscribe to hashchange topic
callback();
connect.subscribe("/dojo/hashchange", null, callback);
});
}); // dojo.ready
}); // require
</script>
If the content you're loading contains javascript you should use dojox.layout.ContentPane.
A new "google related" bar shows up at the bottom of my website. It displays links to my competitors and other things like maps, etc. It is tied in with users using the google toolbar. If anyone has any ideas on how I can disable from displaying on my web side I would sure appreciate it.
Taken from http://harrybailey.com/2011/08/hide-google-related-bar-on-your-website-with-css/
Google inserts an iframe into your html with the class .grelated-iframe
So hiding it is as simple as including the following css:
iframe.grelated-iframe {
display: none;
}
Google removed div and frame names and put everything to important so original answer no longer works on my site. We need to wait for the iframe to be created and then hide it by classname. Couldn't get .delay to work, but this does...today anyway.
$(document).ready(function() {
setTimeout(function(){
$(‘.notranslate’).hide();},1000);
});
Following javascript code tries to find the google related iframe as soon as the window finishes loading. If found, it is made hidden, else an interval of one second is initialized, which checks for the specified iframe and makes it hidden as soon as it is found on page.
$(window).load(function (){
var giframe = null;
var giframecnt = 0;
var giframetmr = -1;
giframe = $("body > iframe.notranslate")[0];
if(giframe != null)
$(giframe).css("display", "none");
else
giframetmr = setInterval(function(){
giframe = $("body > iframe.notranslate")[0];
if(giframe != null) {
clearInterval(giframetmr);
$(giframe).css("display", "none");
} else if(giframecnt >= 20)
clearInterval(giframetmr);
else
giframecnt++;
}, 1000);});
Find the parent DIV element that contains the stuff in the bar. If it has an id or name attribute, and you can control the page CSS then simply add a rule for the element, i.e. if you see something like
<div id="footer-bar-div".....
then add a CSS rule
#footer-bar-div {display:none ! important}
This will not work if the bar is inside an iframe element, but even in that case you should be able to hide it using javascript, but you will need to find the name/id of the frame, i.e.:
var badFrame = document.getElementById('badFrameId').contentWindow;
badFrame.getElementById('footer-bar-div').style.display='none';
if the frame has a name, then instead you should access it with:
var badFrame = window.frames['badFrameName']
There is also a chance that the bar is generated on-the-fly using javascript. If it is added to the end of the page you can simply add a <noscript> tag at the end of your content - this will prevent the javascript from executing. This is an old trick so it might not always work.
I'm using Colorbox to show the html content of hidden divs on my page. I can get this to work perfectly with the following:
$("a.colorbox").colorbox({width:"600px", inline:true, href:"#344"});
This will show the div with the ID of 344.
However, because I'm trying to build a scalable and dynamic page with WordPress, I want to be able to grab the ID of my divs through a function, rather than hard code them in the jquery call.
I modified Jack Moore's example:
$("a[rel='example']").colorbox({title: function(){
var url = $(this).attr('href');
return 'Open In New Window';
}});
so that it looks like this:
$(".colorbox").colorbox({width:"600px", inline:true, href:function(){
var elementID = $(this).attr('id');
return elementID;
}});
The problem with this is that the href property of the colorbox function is looking for a string with a # mark infront of the ID. I tried various ways of concatenating the # to the front of the function, including the # in the return value, and concatenating the # to the elementID variable. No luck.
I also tried using the syntax in Jack's example (with no luck) so that my return statement looked like this:
return "#'+elementID+'";
I think my basic question is: How do I use colorbox to show hidden divs on my page without hardcoding everything?
Thanks for your help,
Jiert
I didn't really like any of the answers given above. This is how I did it (similar but not quite the same).
I also fully commented it for people a bit new to Javascript and the colorbox plug in.
$(document).ready(function() { //waits until the DOM has finished loading
if ($('a.lightboxTrigger').length){ //checks to see if there is a lightbox trigger on the page
$('a.lightboxTrigger').each(function(){ //for every lightbox trigger on the page...
var url = $(this).attr("href"); // sets the link url as the target div of the lightbox
$(url).hide(); //hides the lightbox content div
$(this).colorbox({
inline:true, // so it knows that it's looking for an internal href
href:url, // tells it which content to show
width:"70%",
onOpen:function(){ //triggers a callback when the lightbox opens
$(url).show(); //when the lightbox opens, show the content div
},
onCleanup:function(){
$(url).hide(); //hides the content div when the lightbox closes
}
}).attr("href","javascript:void(0)"); //swaps the href out with a javascript:void(0) after it's saved the href to the url variable to stop the browser doing anything with the link other than launching the lightbox when clicked
//you could also use "return false" for the same effect but I proffered that way
})
}
});
And this is the html:
<a class="lightboxTrigger" href="#lightboxContent">Lightbox trigger</a>
<div id="lightboxContent" class="lightboxContent"> <!-- the class is just to make it easier to style with css if you have multiple lightboxes on the same page -->
<p>Lightbox content goes here</p>
</div>
I think it would work with multiple lightboxes on the one page but I haven't tested it with that.
I'm facing the same issue. What does your html look like? meaning, how did you structure your "divs"
Mine looks like this:
Javascript:
<script>
$(document).ready(function () {
$("a.colorbox").colorbox({ width: "50%", inline: true, href: function () {
var elementID = $(this).attr('id');
return "#" + elementID;
}
});
});
</script>
And the html looks like (I tried changing the display:none):
<a class='colorbox' href="#">Inline HTML</a>
<div style="display:none">
<div id="pop">
This data is to be displayed in colorbox
</div>
</div>
return "#" + elementID;
will have the desired effect as David says.
This is the way I got it to work
HTML: (taken from the example in one of the answers)
<a class="lightboxTrigger" href="#lightboxContent">Lightbox trigger</a>
<div id="lightboxContent" class="lightboxContent"> <!-- the class is just to make it easier to style with css if you have multiple lightboxes on the same page -->
<p>Lightbox content goes here</p>
</div>
Javascript:
$('a.lightboxTrigger').click(function(){
var ref = $(this).attr("href");
$.colorbox({ html: $(ref).html() });
$.colorbox.resize();
});
