Update facebook follow button URL dynamically - javascript

I got following code from facebook developer's page and it work fine:
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.5&appId=916488391727774" ;
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<div class="fb-follow" data-href="https://www.facebook.com/zuck" data-layout="standard" data-show-faces="true"></div>
I want that whenever user update input field with his profile URL, follow button should update and display his record instead of zuck's default account. How is it possible with jquery/javascript?
Note:- I just used the above code for fb-follow button and didn't used it's API's or anything extra.

Facebook login button just won't show up

I went to this page : https://developers.facebook.com/docs/facebook-login/web/login-button
I copied and pasted the code they give, in my HTML index:
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.8";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
(that's right after the body tag, as they recommend), and then :
<div class="fb-login-button" data-max-rows="1" data-size="icon" data-show-faces="false" data-auto-logout-link="false"></div>
anywhere in the page, it doesn't work. The button does not show up. If I add a red border to it, a vertical red line appears, showing that the button doesn't render.
I have tried with different options, locally, on my server, and in a codepen (http://codepen.io/jeremythille/pen/EWWRdy?editors=1100), no avail.
No error in the console, no problem in the network tab. "sdk.js" is found and loaded.
What am I missing?

You need to initialize the facebook sdk first. See this page: https://developers.facebook.com/docs/javascript/quickstart

Unable to dynamically render a Facebook embedded post in JQuery

Example
Facebook Embedded Post Document
I cannot get iframe to work in jsfiddle but hope you can understand the code. I'm trying to load a facebook post dynamically. I read that FB.XFBML.parse(document.getElementById(idName)); is the way to go to specially render a single post, so that the function doesn't have to render all embedded posts on the page over and over again when a new post is dynamically created.
But I cannot get that to work. The only way I can get that to render is FB.XFBML.parse();, but that seems not to be an ideal way of doing that for just rendering a specific post. Can anyone figure out what's the problem with FB.XFBML.parse(document.getElementById(idName));?
var facebookScriptId = 'facebook-jssdk';
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.2";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', facebookScriptId));
$('button').click(function(){
var id = $('span').text(),
idName = 'fb'+id;
$('div').replaceWith('<div id="'+idName+'" class="fb-post" data-href="https://www.facebook.com/FacebookDevelopers/posts/'+id+'"></div>')
FB.XFBML.parse(document.getElementById(idName));
})
<button>Click</button>
<div></div>
<span>10152128760693553</span>

Facebook like appears only after reload of the website

I use the facebook like and share button on my website. However on some pages the button just appears after I refresh the website (F5). I use the following code:
<body>
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.0";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
And then further down where I want my like and share buttons (this part is in haml):
%div.fb-like{"data-href" => "http://www.mywebsite.com#{request.fullpath}", "data-send" => "true", "data-width" => "450", "data-layout" => "button_count", "data-show-faces" => "false", "data-font" => "arial"}
When I click on a link and land on any page the buttons do not show up, when I press F5 the buttons show up after the reload.
I use Ruby on Rails 4.0, jQuery and I also use turbolinks with rails (I'm not sure, but this migt be a problem).

Recall javascript on click in tumblr

I've added the facebook like button on my tumblr page. But each time I click on the "load more" button, the facebook button doesn't appear on the next articles. I think I have to recall the facebook script at this moment to make it work. But i don't know how.
Here is the facebook script I have in my body:
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/fr_FR/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
And here is the part of the footer where I have to load the rest of the post on my page (I think…):
<footer{block:PermalinkPage} class="individual-footer"{/block:PermalinkPage}>
{block:IndexPage}
{block:IfLoadMoreLink}
<div class="load-more">
{block:IfLoadMoreText}{text:Load More Text}{block:IfLoadMoreText}
</div>
{/block:IfLoadMoreLink}
▲
{/block:IndexPage}
Thx for your help.

Check if user liked my page or not using page url and appId

From https://developers.facebook.com/docs/reference/plugins/like/ I got this script to show the like button in my website
<div id="fb-root"></div>
<script>
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/fr_FR/all.js#xfbml=1&appId=155899567847";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
<div class="fb-like" data-href="http://website.com/project/hello" data-send="false" data-layout="button_count" data-width="100" data-show-faces="false"></div>
I only have the appId and the url, can I check is current user liked my page ?
I looked in google and I found some examples using PageId and I dont know how to get it

PageID is necessary for checking that page is already liked or not from another source. If you are in the same page (your facebook page) it means there is no need to get that id as it will automatically have it from the session or somewhere else.
You can get the PAGE ID by one of the following way,
