reCaptcha not shows on my singlepage website

I have some problem with the recaptcha loading.
I trying to remake and modernize one of old my website to a singlepage one with php, javascript and ajax (no jquery!).
Everyting is fine yet, but the recaptca. I use the following method.
index.php contains the "main frame" and the target divs to the HTTPRequest function.
With AJAX I load the PHP page templates to the main target divs.
BUT when my PHP template file looks the following to show the registration last page with the captcha:
<?php
$template = '
.../ some code sits here /...
<div class="w80">
<div class="g-recaptcha" data-sitekey=".../ my sitekey sits here /..."></div>
</div>
<div class="flex-row fr-c mt50a">
<button class="button btn-reg" onclick="switchPage(\'registration_page_2.php\')">« Back</button>
<button class="button btn-reg" onclick="validatePage(\'registration_validate.php\')">Submit your registration</button>
</div>
';
echo $template;
and I load it into one of my divs, the reCaptcha has not been shown. I tried some ways and tricks, but it's not working.
There is no form and submit section at all on my page. I do it with javascript and ajax.
Why I cannot make it works?
Is that possible to bypass form->submit->post method to get reCaptcha alive?
Or is the singlepage the wrong way?

I don't quite understand you but since i can't post a comment, i will attempt to answer anyway.
You don't have to use php to echo the html code, just in-case you didn't know, you can do it like this.
<?php
//php code
?>
<div class="w80">
<div class="g-recaptcha" data-sitekey=".../ my sitekey sits here /..."></div>
</div>
<div class="flex-row fr-c mt50a">
<button class="button btn-reg" onclick="switchPage('registration_page_2.php')">« Back</button>
<button class="button btn-reg" onclick="validatePage('registration_validate.php')">Submit your registration</button>
</div>
<?php //continue code here ?>
and I load it into one of my divs, the reCaptcha has not been shown. I
tried some ways and tricks, but its not works :(
It's hard to tell from the information you have given why it is not being shown
There is no form and submit section at all on my page. I do it with
javascript and ajax.
If your registration_page_2.php and registration_validate.php does not echo the template in your current .php shown, then it certainly wouldn't appear on your page
Why I cannot make it works? Is that possible to bypass
form->submit->post method to get reCaptcha alive? Or is the singlepage
the wrong way?
I think you just did something wrong in the middle. The way you have said is 'form->submit->post' is the right way to go about this
Can you help me to get the solution please?
Using your browser, inspect or view the source code of your page. (For google chrome the hotkey is CTRL+SHIFT+I) Try to find the elements in your page to see if they are loaded, but hidden due to css or the likes. After which, you should give more details.

update your captcha block with adding id recaptcha
<div class="g-recaptcha" id="recaptcha" data-sitekey=".../ my sitekey sits here /..."></div>
add following code in your page load
<script src='https://www.google.com/recaptcha/api.js?hl=en&render=explicit&onload=onReCaptchaLoad'></script>
<script type="text/javascript">
var recaptcha;
var onReCaptchaLoad = function(){
recaptcha = grecaptcha.render('recaptcha',{
'sitekey' : 'YOUR_RECAPTCHA_PUBLIC_KEY',
'theme' : 'white'
});
};
</script>

You can do it with php request
<?php
if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])){
$recaptcha = $_POST['g-recaptcha-response'];
$recaptcha_secret = 'YOUR_RECAPTCHA_SECRET_KEY'
$verify = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret={$recaptcha_secret}&response={$recaptcha}");
$captcha_success = json_decode($verify);
if($captcha_success->success){
// success
}else{
// error
}
}
?>

JQUERY Ajax When I Click A Href

I am new to JavaScript, Jquery and Ajax. This is what I am trying to do:
When I click on Pro-Hashtagh, I want to display a word in Show-Id.
This Pro-Hashtagh HTML code:
<li>
Pro Hashtagh
</li>
Show-Id HTML code:
<div class="body" id="Show-Id">
</div>
Ajax Code:
<script type="text/javascript">
$(function () {
var waiting = '<center><h3>Please Wait ...</h3></center>';
$('#Pro-Hashtagh').click(function(){
$("#Show-Id").html(waiting);
});
});
</script>
But when I click, nothing happens

I just created a fiddle with your code and everything seams to be fine.
https://jsfiddle.net/eh2xbxpe/
Of course you have to add Jquery to your project, that'S the only error I see.
Beside, you don't call any AJAX request in your code, you are just adding a please wait. If you are trying to reach an external ressources via AJAX, it is not the case here.
$(function () {
var waiting = '<center><h3>Please Wait ...</h3></center>';
$('#Pro-Hashtagh').click(function(){
$("#Show-Id").html(waiting);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<li>
Pro Hashtagh
</li>
<div class="body" id="Show-Id">
</div>

I guess you're working on a local environment.
Something happens when you click on the link but the page reloads way to fast for you to see anything. You need to update your onclick event so it prevent the link default behavior.
$('#Pro-Hashtagh').click(function(event){
event.preventDefault();
$("#Show-Id").html(waiting);
});

try
Pro Hashtagh
and create check function in javascript

<script
src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<div class="body" id="Show-Id">
</div>
<li>
Pro Hashtagh
</li>
<script type="text/javascript">
$(function () {
var waiting = '<center><h3>Please Wait> .
..</h3></center>';
$('#Pro-Hashtagh').click(function(){
$("#Show-Id").html(waiting);
});
});
</script>

Execute custom script after page loaded with Ratchet\Push.js

So on the GitHub documentation for Ratchet 2.0.2 I found the following statement.
Script tags containing JavaScript will not be executed on pages that
are loaded with push.js. If you would like to attach event handlers to
elements on other pages, document-level event delegation is a common
solution.
Can someone please spell out exactly how to get a custom <script> to execute after being loaded by Push.js?
On my first page, I have a Table view, with several links to other pages, one of them being a link to a second page with a Twitter Feed widget on it.
<li class="table-view-cell media">
<a class="navigate-right" href="Twitter.php" data-transition="slide-in">
<span class="media-object pull-left icon icon-person"></span>
<div class="media-body">
Twitter Feed
</div>
</a>
</li>
The second page only contains the twitter feed widget code. When I browse to this page directly (without being loaded by Push.js) everything loads correctly, but when it is loaded via Push.js, the script is not executed.
Can someone please explain what I need to do to get this script to execute after being loaded by Push.js? I've searched Google, Stack Exchange, and Github\Ratchet issues and have not been able to find a good example of how to accomplish this.
One solution would be to add data-ignore="push" to the link, but I want to know how to do with WITH push.js.
<div class="content">
<a class="twitter-timeline" href="https://twitter.com/XXXX" data-widget-id="XXXX">Tweets by XXX</a>
</div>
<script>
!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");
</script>

EDIT: below was how I originally solved this problem, which worked fine, but I came up with a better solution, which I posted as the answer to this question.
I finally figured it out.
On your first page, you need to do the following...
var checkPage = function(){
//Only run if twitter-widget exists on page
if(document.getElementById('twitter-widget')) {
loadTwitterFeed(document,"script","twitter-wjs");
}
};
window.addEventListener('push', checkPage);
checkPage() will execute for every time a new page is loaded via push.

Just made a change for Ratchet.js to make individual js works for each page more elegant.(https://github.com/mazong1123/ratchet-pro)
By using the new ratchetPro.js, we can do followings:
(function () {
var rachetPageManager = new window.RATCHET.Class.PageManager();
rachetPageManager.ready(function () {
// Put your logic here.
});
})();

Return to the previous page with inputs

Really unsure about the title question. Feel free to suggest. :)
Hi guys! I created a very simple code, that would represent my web.
Here is my home page:
<html>
<script type="text/javascript">
function getPage(linkPage,variables,divName){
$.get(linkPage + "?" + variables,function(data){$(divName).html(data);});
}
function show(){
//functionName("path","data","idName");
getPage("AjaxPages/hi.php","","#container");
}
</script>
<body>
<div id="container">
First Name<input type="text" />
<input type="button" value="next" onClick="show();"/>
</div>
</body>
</html>
Basically, it ask for information, Name for example. When the button NEXT is click it will call a javascript function that will call a certain page or the NEXT PAGE that will load on the div with the Id Container.
NEXT PAGE
On the next page, it will then ask another question, like Last Name for example. But then, I want to go back to the previous page to make same changes.
HERE is the code:
<script type="text/javascript">
function show(){
ajaxgetdata("index.php","","#container1");
}
</script>
<div id="container">
Last Name<input type="text" />
what to make changes on the previous page?<input type="button" value="back" onClick="show();"/>
</div>
When button back is clicked, it will just call the previous page, but will not include the text that you input on the textbox.
I know that it happens because it just call the page..
Is there a way? that when back button is clicked, it will reload the previous page, with all the contents/inputs.
:) :( :'( :/ :|

Don't load any additional pages. Do everything with AJAX.
If you don't want, some server-side script may help :D

If you can use HTML5 in your site, you can take a look at the History API which can handle navigation and fires a "popstate" event, to which you can pass data.
There's a good example here:
http://diveintohtml5.info/history.html
You could do something like this:
window.addEventListener("popstate", function(e) {
if(!e.state || !e.state.firstName) {
return;
}
document.getElementById('firstName').value = e.state.firstName;
});
That even will trigger everytime you go back or forward, and you could just organize some function or array with the information you need.
Hope it helps.

I need some help with the Load function in JQuery

I currently have links w/ class="ajax" that I want to retrieve the element with id="test" from the file "data.html" in the same directory, and put that content into the id="content" div on my page:
<script>
$(document).ready(function(){
$("a.ajax").click(function(event){
$("#content").load("/data #test");
});
});
</script>
<a class="ajax" href="#">Text</a>
<div id="content"></div>
and externally, but in the same directory, I have data.html:
<div id="test">Will this show up?</div>
On the clicking of the anchor, Safari reports "page loading interupted", and no change occurs.
I definitely have JQuery called in the header. Can I get some help with this function? Thanks!

You have /data but the file is /data.html, assuming you're in the root. :)
I just tested what you have with this change and it works fine for me. I also recommend you get a tool like Firebug so you can easily see what your AJAX requests are doing.

$.ajax({
url: "data.html",
type: "POST",
success: function (answer) {
$("main_content").html($(answer).find("div#content_id").html());
}
});
I hope it will help you.
