How do I hide a tag in jQuery within HTML loaded via AJAX

This post is actually a continuation of the following:
https://www.experts-exchange.com/questions/28360042/jQuery-does-not-trigger-on-HTML-loaded-via-AJAX-call.html

I now want to hide a link within the loaded HTML.

The parent code is here:

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Test</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
</head>

<body>

	<script type="text/javascript">
    //<![CDATA[
    $(document).ready(function(){

        $('#internaldiv').load('link.htm');

        $('#internallink2').hide();

		$(document).on("click",".link",function(){		
		   alert("Link clicked");
		   return false;
		});

    });
    //]]>
    </script>
    
    <a class="link" href="#">Click parent link</a>
    
    <div id="internaldiv">
    
    </div>

</body>
</html>

Open in new window

The HTML to load is here:

<a class="link" href="#">Click loaded link</a><br>
<a class="link" id="internallink2" href="#">Click loaded link 2</a>

Open in new window

I am trying to hide internallink2 but the following jQuery does not work:
$('#internallink2').hide();

I know this somehow needs to change but not exactly sure what the syntax is as this time the trigger is the HTML snippet loading.

Ok thanks Cathal. I have now changed the code to the following:

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Test</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
</head>

<body>

	<script type="text/javascript">
    //<![CDATA[
    $(document).ready(function(){
		
		// Do a synchronous call to load the 
		$.ajax ({
			type: 'GET', 
			url: 'link.htm', 
			success: function(response) {
			   $('#internaldiv').html(response)
			   $('#internallink2').hide(); // Now you can hide it as the html has been loaded.
			 }
		});		

		$(document).on("click",".link",function(){		
		   alert("Link clicked");
		   return false;
		});

    });
    //]]>
    </script>
    
    <a class="link" href="#">Click parent linkx</a>
    
    <div id="internaldiv">
    
    </div>

</body>
</html>

Open in new window

So the synchronous AJAX call now does the load as well.

It's asynchronous
A synchronous call would block all further processing until the current function has finished - but this should not be used/or at the very least avoided.
