How can I prevent href redirect onclick

Question

I have a div what acts like a button(.butt), when I click it, It should prevent a href from redirecting and open a input. It dosent work, it still redirects and when I go back from redirection the input appears, but when I press the input it still redirects.

How can I make it so that when I press my div it disables the redirection and lets my insert a value into input to change the value?

var x;
var h = 0; // blur fires multiple times, use h to count and fire once
var url = 'up.php';

$(".butt").on('click', function(event) { 
event.preventDefault();
$(".tk").on('click', function(d) { 
	d.stopPropagation();
	var x = $(d.target); 
	x.html('<input  id="edit2" style="width: 40px;" value="'+x.text()+'">'); 
	var this_id = x.context.id;
	
	$("#edit2").on('blur', function(d) { 
		if (h < 1) {
			h = h+1;
			d.stopPropagation();
			
			$(d.target.parentElement).text(d.target.value);
			
			$.get(url,  {id: this_id, value: d.target.value})
				.done(function(d){ if(d == undefined || d != 1) { alert('Something went wrong, check your data and results. '+d);}})
				.fail(function(d){ alert('error');});
			$("#edit2").off('blur');
		}
		
		
	});	
	h = 0;
});
});

.butt{width:15px;height:15px; background-color:red;border-radius: 50%;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="butt"> </div>
<a href="http://www.google.com" class="tk">click</a>

Solution

You can use preventDefault

The event.preventDefault() method stops the default action of an element from happening.

d.preventDefault();

var x;
var h = 0; // blur fires multiple times, use h to count and fire once
var url = 'up.php';

$(".butt").on('click', function(d) { 
$(this).on("click", function(){return false;})
$(".tk").on('click', function(d) { 
    d.preventDefault();
	d.stopPropagation();
	var x = $(d.target); 
	x.html('<input  id="edit2" style="width: 40px;" value="'+x.text()+'">'); 
	var this_id = x.context.id;
	
	$("#edit2").on('blur', function(d) { 
		if (h < 1) {
			h = h+1;
			d.stopPropagation();
			
			$(d.target.parentElement).text(d.target.value);
			
			$.get(url,  {id: this_id, value: d.target.value})
				.done(function(d){ if(d == undefined || d != 1) { alert('Something went wrong, check your data and results. '+d);}})
				.fail(function(d){ alert('error');});
			$("#edit2").off('blur');
		}
		
		
	});	
	h = 0;
});
});

.butt{width:15px;height:15px; background-color:red;border-radius: 50%;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="butt"> </div>
<a href="http://www.google.com" class="tk">click</a>
