Currently I am using the twitter bootstrap tabs on a page with the following code. I added a bit of javascript/jquery to push hash tags in the url, so I can actually link to a tab. This works fine, but the when I load the first tab I see the whole page and then I am quickly shown just the first tab. Now, if I click tabs on the page everything works nicely and I am not shown the whole page again. This flash of data is annoying to say the least. Any ideas on what I am doing wrong?
Jade Template Code, compiles down to standard HTML
div(class="tabbable")
ul(id="myTab", class="nav nav-tabs")
li
a(href="#surveyEditData", data-toggle="tab") Survey
li
a(href="#surveyEditQuestions", data-toggle="tab") Questions
...etc...
JavaScript code:
$(function(){
// Function to activate the tab
function activateTab() {
var activeTab = $('[href=' + window.location.hash.replace('/', '') + ']');
activeTab && activeTab.tab('show');
}
// Trigger when the page loads
activateTab();
});
You are seeing the delay in the HTML being rendered before the Javascript is done executing.
To fix this, you need to put an initial CSS style such as fade or hide to all the other tabs, except the first one.
CSS rules are executed immediately during rendering, so there will be no delay for these rules.

I am working with this Template from templatemo.
I wanted to include some references to other parts of the website in the body text (e.g. Please "contact me" for further information). If you click "contact me" the page should navigate to "Contact" in the same manner as if the user clicked on the navigation bar to navigate to the page (with the same animation).
In order to so, i added the following code to trigger a click event:
<p class="tm-text">Contact me via the <a id="myLink" href="javascript:loadPage(5);">contact form</a></p>
And the function to trigger the click:
function loadPage(pageNo) {
$(document).ready(function() {
$('.nav-item').get(pageNo).click();});
}
So this code is working, if I click on the reference the page changes as if I clicked the navigation bar. BUT:
If I reload the page and click on the reference, the page navigates to the contact page, which then however is not diplayed properly (the contact form and the google maps view are missing).
If I reload the page, first open the contact page via the menu, then switch to the page with the reference and click on it, the contact page is loaded properly.
This behaviour is also shown if I reference another page (e.g. the Gallery). The gallery elements are displayed (the page is not completely empty), but the spacing between the elements is not correct.
It seems like every page has to be loaded at least once via the navigation bar. If this has happened, all pages are displayed properly when opened via a reference in the text.
Thanks for your support.
Your template use Hero slider + some customs JavaScript functions to move between "pages", so you need to use the same functions to get the same behaviour.
Doing that will work:
<p class="tm-text">Contact me via the <a id="myLink" href="javascript:goToPage('Contact');">contact form</a></p>
You need to add this JS function:
function goToPage(page_name) {
// Retrieve the <a> tag with the page_name
// page_name is the string of the page in the navbar
page_link_a = $('.navbar-nav .nav-link').filter(function(index) { return $(this).text() === page_name; });
page_link_li = page_link_a.parent();
// Trigger js code from hero slider
page_link_li.click();
// Trigger js code from templatemo
page_link_a.click();
}
The function goToPage() take one parameter, the string name of the section so if you have a section named My Gallery you need to put that, not my-gallery nor an index.
Is there a way to open a specific artical via an external link and focus on it when the links open on a one page wepage?
I have a webpage that shows content as you click on links by hiding and showing the divs. What i want is to make an external link to my webpage in the form of mywebpage/(div's name) and have the link open my page but showing the content of that div right away, instead of its usual opening content you would get when clicking on just the ordinary mywebpage link.
Is it possible? And how?
Short answer: yes.
Long answer: You will have to examine the URL's hash on page load and manually translate that into hidden or shown divs (or other positioning).
While you're at it, you could include browser history support when your divs are opened and closed.
Pulling apart what I did for http://www.tipmedia.com (Segment starts on line 322 of the page source)
//on page ready
$(document).ready(function() {
//examine hash
if(window.location.hash == "#thanks") {
//scroll to an anchor tag, slight delay to insure correct page height
setTimeout(function() {
$('html,body').animate({scrollTop:$("#contact").offset().top}, 0);
},500);
//hide and show necessary divs
$("#contactThanks").css({"display":"block"});
$("#contactIndex").css({"display":"none"});
$("#contactGeneral").css({"display":"none"});
$("#contactMeeting").css({"display":"none"});
$("#contactCareers").css({"display":"none"});
//clear the hash (not necessary for your use)
window.location.hash = "";
}
}
The history stuff is easy too, I used Modernizer.js for the best cross browser support, but it looks like this (non-Modernizer use is very similar)
//during the hide/show of new content...
//if history is available
if(Modernizr.history) {
//this data is whatever it is you wish to save
lastPageState = { div:divName, pos:amount, page:lastLoadedPage };
history.pushState(lastPageState, divName.substring(1,divName.length-6), "index.html");
}
//...
//then later, the popsate event handler
window.onpopstate = function(event) {
//examine event.state and do whatever you need to
//example segment starts line 989
//Whatever data you saved would be read here and you would do the appropriate action,
//hiding or showing divs, reloading AJAX content, etc.
}
Yes, you can use an anchor link.
So in your target page name the div with an id,say div id="target".
Then in the referring page use a link in this form
Referring Page:
GO to Target Info...
Target Page:
<div id="target">
...content...
</div>
FYI-"target" is just an example name, it could be anything...
Im using javascript - ajax and jquery to load all contents from php files which is under (#menu a)[see below 'you.php'] without refreshing the page when navigating across the page - which works perfectly.
However, how do I create a hyperlink of somesort on content-A (which loads and shows all the contents from home.php) when clicked, it relocates & shows the user to/the contents of settings.php(B).
Please note my href hyperlinks doesn't have .php at the end. The 'general.js' file explains why.
(you.php):
<div id="menu">
Home
Settings // Content (A)
</div>
<div id="content"><div>
<script src="./js/jquery-2.1.4.min.js"></script>
<script src="./js/general.js"></script>
(general.js):
$(document).ready(function() {
// initial content that will be loaded first upon logging in:
$('#content').load('home.php');
// handle menu clicks
$('#menu a').click(function(){
var page = $(this).attr('href');
$('#content').load('' + page + '.php');
return false;
});
});
(home.php):
<h1> welcome to homepage </h1>
Would you like to go to your settings?
Click here: <a href="settings.php>Settings</a>
Obviously the problem with doing the href hyperlink like this in home.php, is that it goes directly to the settings.php page. Which makes my general.js (ajax) and jquery file pointless.
Since the whole point of using ajax and jquery is for smooth navigation and no page refresh upon navigating around the website.
and No, I do not want to load the contents of settings.php within the contents of home.php, 'loadception' is not what I'm looking for.
This is my simple question, I would like a simple answer in php,javascript,ajax.
Any ideas?
You need to use event delegation. To better performance in my example, all links that must be loaded into "#content" have a class "open" so, in jquery you could do some like this:
$('#content').on('click', '.open', function(e) {
e.preventDefault();
var page = $(this).attr('href');
$('#content').load('' + page + '.php'); // concat .php if it's only necessary
});
Updated
I created a demo on github: https://github.com/josemato/stackoverflow/tree/master/spa-event-delegation
So I got this code
Javascript:
<script type="text/javascript">
$(function(){
$('.ajax') .click(function(e){
e.preventDefault()
$('#content').load( 'file.htm' )
})
})
</script>
html:
Link
it works perfectly in firefox, but nothing happens when I click the link in chrome and IE simply opens a new window with the file. any advice?
I am not a coder of any sort, and I know there is more than one way to make this work.
This is what worked for me for MY situation.
I had a working site but with A LOT of code / DIV content all in one page and I wanted to clean that up.
I hope this Helps someone else!
I have been searching for this solution for quite some time and I have run across many examples of how it can work in different instances.
My scenario was as follows:
I have a photography website that uses a series of DIV tags containing the various "pages" so to speak of the site.
These were all set as:
<div id="DivId" style="display:none"></div>
The following script in the head of the page:
$(document).ready(function(){
$('a').click(function () {
var divname= this.name;
$("#"+divname).show("slow").siblings().hide("slow");
});
});
</script>
and called using the anchor links like this:
HOME
Where name was the name of the DIV to be called.
Please note the DIV will be called inside the parent container DIV.
Lastly and most importantly for this particular question and scenario, the DIV were all placed on the page as shown above.
Each div content was created just as if it were within the DIV tags but minus the opening and closing DIV tags and then saved as a separate .txt file, and called by placing this is the head of the parent page:
src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js">
and
$(document).ready(function() { // this runs as soon as the page is ready (DOM is loaded)
$("#DivName") // selecting "div" (you can also select the element by its id or class like in css )
.load("PathToFile.txt");// load in the file specified
$("#AnotherDiv").load("AnotherFile.txt");// Additional DIV can be added to populate DIVs on th eparent page.
});
Change the link to href="#" or "javascript:void(0);return false;"
<a class='ajax' href='#'>...</a>
The loading logic is all in your ajax call. But, you have also a link which points to the file, too.
So, it seems that some browsers give different priorities on how the click is handled.
Anyway, links that do something other than changing page (f.ex. executing js) shouldn't have an explicit HREF attribute other than something that "does nothing" (like above)
I believe the problem is that the script loads before the document is loaded.
try this:
$(document).ready(function (){
$('.ajax').click(function(e){
e.preventDefault()
$('#content').load( 'file.htm' )
});
});
I am not sure, but i can not see any other problem.
I have the following code that gets the value of a drop down list and displays the value.php and valueb.php files in different divs. I already added a loading class, but I can't remove it when the page is loaded.
I tried .removeClass('loading') before the end of statement with no result (when i add the removeclass, the pic is not loading).
The follow displays the loading pic onChange and stays showing. Thank you.
$('#result').empty().addClass('loading').load(val + '.php');
Try
$('#firstresult').empty().addClass('loading').load(val + '.php', function(){$('#firstresult').removeClass('loading'); });
