Link to open tab from menu help. jQuery Tabslet

I'm wanting to link to a certain tab (Portfolio Tab) on a page from the main menu of a website, so when clicked it goes to that page with that portfolio tab open.
So far I've come up with this (using jQuery Tabslet) which works when not on the same page, but doesn't work if the user happens to be on the same page as the tabs, and so does nothing.
The link I use in the main menu is /about/#tab-3 which is doing the job of going to the about page with the portfolio tab open.
I thought I may need to trigger a page refresh when on the same page? And perhaps remove the #tab-3 from the url too.
Not being a jQuery expert, I unfortunately just don't know.
Here is the code so far
Thanks in advance.
jQuery(document).ready(function($){
$('.tabs').tabslet({
active :1,
animation : true,
container: '.tabs-container'
});
var hash = $.trim( window.location.hash );
var anchor = $('a[href$="'+hash+'"]');
if (anchor.length > 0){
anchor.click();
}
window.onload = function () {
if (location.hash) {
window.scrollTo(0, 0);
}
};
});

Advise: Always mention a reference to the plugin you use. I assume here you talk about this one.
This plugin acts on tab click only.
So when using a window hash in a link from another page like you do, you have to "simulate" a click on the tab.
So you will use an attribute selector to find the anchor having a href corresponding to the hash...
And click it.
window.onload = function () {
if (location.hash) {
window.scrollTo(0, 0);
$("a[href='"+location.hash+"']").click(); // Add this!
}
};

How to trigger iframe load event more than once when changing iframe source

I have an iframe that links to another internal web application.
There's a side panel with a list of links that changes the src of the iframe. Sometimes if there's a lot of data, the iframe site takes a while to load. I want to put a spinner icon when a link is clicked and hide it when the frame is loaded.
I change the src using $('#myiframe').attr('src', urlVar) in a click function for the links. I can show the spinner on click.
The problem is, how do I hide it? How do I find out that the iframe has finished loading?
I tried using $('#myiframe').load(function() { }) but that only works on the initial load (i.e. for the first link I click), not for subsequent loads (if I click on another link).

This javascript works for me :
function loadNewUrl (url){
if(url === undefined) url = 'http://example.com?v=' + Math.random();
var ifr = document.getElementById('myiframe');
ifr.setAttribute('src',url);
ifr.onload = function() {
alert('loaded');
};
}

Change right click "Copy link" value

I am currently working on an affiliate website. I have made a script in jQuery that shows the sales page (without affiliate link) when hovering, but when you click on it, it adds my affiliate link to the beginning of the link. Then my network redirects them to the desired page.
EDIT: To clarify, I want to say that I am talking about hovering over links
Now, if you right click on it, a menu opens, and you can click "Copy link". This copies the "xxx" in:
Example
Which is without my affiliate link. How do I make the "Copy link" button copy another link than the href in the a tag? Is it even possible?
Right now I avoid it completely by having this in the beginning of my code:
.on("click contextmenu", function(){};
To give you an example of the current code, it works by listening to clicks on a tags with a specific class, then it checks if the href in the a tag contains some text, if it contains that text, it does this:
window.location.href = affiliatelink + link;
If it doesn't, it does this (if I don't have an affiliate link for that product):
window.location.href = link;
So, is my problem possible to solve - or do I have to do it, like I am doing it?
EDIT 2: I have to provide my code
$(document).ready(function(){
$(".class").on("click contextmenu", function(){
var link = this.href;
var partner = "https://affiliatelink.com/?url=";
if(link.indexOf("partnername") != -1){
window.location.href = partner + link;
} else {
window.location.href = link;
}
});});

Assuming I'm understanding your question correctly, it might be possible to solve if you change when you're appending your affiliate code to links.
The "copy link address" context menu shortcut is going to copy whatever is in the href attribute of a link tag. So, what if you set that attribute's value to your affiliate link + the original link's text? You would no longer need to do it in a click handler; it would "just work" and would support both cases.
Something like this might do the trick:
var links = [].slice.call(document.querySelector('.your-class'));
links.forEach(function(link){
link.href = affiliateLink + link.href;
});
You'd no longer need your click handler, and it supports both cases of interacting with links.
EDIT: Updated with your code sample.
$(document).ready(function(){
$(".class").each(function(){
var link = this.href;
var partner = "https://affiliatelink.com/?url=";
if(link.indexOf("partnername") != -1){
this.href = partner + link;
}
});});

How to set the title for the new browser tab?

I have a question about the new tab for the link.
Is there anyway I can set the browser tab title before user clicks a link? It seems like there is no way to debate the title for the new tab if the html contained in the new tab doesn't have title attribute. Am I right? How do I set the title?
//the href is dynamic so I can't set them one by one because I have 100+ html file here
<a href="test.html" target="_blank">open me<a>

As you have it, this is not possible because your links are just normal HTML links. When the new page opens in a new tab, the current page will not have any reference to it and so cannot change it in any way. You will need to open the page using javascript and set the title that way.
You can dynamically set this up in window onload to find all a tags and add a click event whihc opens the window and sets the title.
If you want different titles for each page, you can store this in a data- attribute in the a tag.
Note tho that this will only work with pages in the same domain (for security), and that it does not handle people right clicking and pressing "Open in New Window". Middle click in Windows does seem to work however.
HTML
open me
JavaScript
window.addEventListener("load", function() {
// does the actual opening
function openWindow(event) {
event = event || window.event;
// find the url and title to set
var href = this.getAttribute("href");
var newTitle = this.getAttribute("data-title");
// or if you work the title out some other way...
// var newTitle = "Some constant string";
// open the window
var newWin = window.open(href, "_blank");
// add a load listener to the window so that the title gets changed on page load
newWin.addEventListener("load", function() {
newWin.document.title = newTitle;
});
// stop the default `a` link or you will get 2 new windows!
event.returnValue = false;
}
// find all a tags opening in a new window
var links = document.querySelectorAll("a[target=_blank][data-title]");
// or this if you don't want to store custom titles with each link
//var links = document.querySelectorAll("a[target=_blank]");
// add a click event for each so we can do our own thing
for(var i = 0; i < links.length; i++) {
links[i].addEventListener("click", openWindow.bind(links[i]));
}
});
Sample JsFiddle

You can pass the title with hash and get it on another page, if this another page is yours and you can modify its code.
1st page:
...
<a href="test.html#the_title_you_want" target="_blank">open me<a>
...
2nd page - modify the body opening tag like this:
<body onload="document.title=window.location.hash.replace('#','');">
If the page you are linking to isn't yours, you can use window.open method:
open me

I have not seen addEventListener work reliably, especially when opening a new page using javascript. The best way to change the tab title and have it work reliably is to set a timeout until the page loads. You may have to play with the timeout value, but it works.
var newWindow = window.open(url, '_blank');
setTimeout(function () {
newWindow.document.title = "My Tab Name";
}, 100);

You have two options. Using pure HTML, you can let the user open up links, then later on change the title. Or you can change the title with inline JavaScript. Here's how you do both:
Method 1
Change your links by assigning a target attribute, and then later on use that window name to control the document. For instance in your links it would be: <a href="whatever" target="theNewWindow">. Whenever you want to change the title for this page, you'd use JavaScript as such: window.open("", "theNewWindow").document.title = "New Page Title!"; The problem with this method however is that all links with that target/window name will open in that same window. In addition, after the first time the link is clicked, your browser won't automatically switch to the new tab/window.
Method 2
Change your links by assigning an onclick attribute, which would open the link manually and change the title of the page immediately. Basically it would come down to look like: <a href="whatever" onclick="var w=window.open(this.href, '_blank'); (w.onload=function(){w.document.title='New Page Title!';})(); return false;">. This opens the window based on the href attribute, immediately changes the title, and sets the window to change the title to that when it finishes loading (just in case there really was a title tag).
The problem with both of these methods (as mentioned by others) is your html files have to be on the same domain.

The simplest way is a follows:
var winTab = window.open("", "_blank")
//Open URL by writing iframe with given URL
winTab.document.write("write iframe with your url in src here")
//Set Title for the new tab
winTab.document.title = "Form Title"

You could make your own Page 2 that opens up the other pages (the ones you can't edit), in a frameset. You can then either change the title dynamically when loading your page 2, or as others have suggested if you use window.open you can control the title from the parent page.

If you are in page 1, and opening page 2 in a new tab, you can't set title for page 2 from page 1.
If you have access to page 2 then it's possible, otherwise not.

Always open a html page in fancyBox iframe

I use Fancybox to display external html pages in fancybox, for example : In page1 I set a link, which opens page2 in fancybox iframe mode, and that works fine.
The question is :
Is it possible that if somebody tries to enter the URL of page2, make page2 to always open in fancybox from within page1 instead of the browser window like a normal page?

Yes, it's possible.
So page one (parent.html), will open page two (iframed.html) in fancybox from a link like
<a id="openIframe" class="fancybox" href="iframed.html">Open page inside fancybox iframe</a>
Notice that I set an ID and a class to the link that will open the iframed page.
Then the script for each page:
parent.html
parent page should have two specific codes :
a code to initialize fancybox
a code to detect when a hash is present in the URL so it can fire fancybox
so :
// initialize fancybox
$(".fancybox").fancybox({
// API options
type: "iframe" //<== at least this one
});
if (window.location.hash) {
// detect if URL has hash and trigger fancybox
$(window.location.hash + ".fancybox").trigger("click");
// remove hash after fancybox was opened
// two methods to cover most browsers
if (navigator.userAgent.match(/msie/i)) {
var loc = window.location.href;
index = loc.indexOf('#');
if (index > 0) {
window.location = loc.substring(0, index);
}
} else {
history.pushState("", document.title, window.location.pathname);
};
};
Then the second page (iframed.html) should have a code that detects if itself has been opened inside an iframe or not (the fancybox iframe in our case).
If not, it should redirect to the parent page, targeting the ID of the link that opens fancybox so :
iframed.html
if (self == top) {
window.location.href = "parent.html#openIframe";
};
Notice that self == top will return true if the page wasn't opened inside an iframe so it redirects to parent.
See JSFIDDLE (and try also opening the link in a new window/tab)
