How to run a SweetAlert instead of default javascr

Currently this is the code I use to run a normal confirm window based on the class "confirmation". This is all done with an href link and not on a button onClick event. As the result of the click is to run another code snipped placed in a different file (with the intention to delete a row in db).

$('.confirmation').on('click', function () {
        return confirm('Er du sikker på at du vil slette?');
    });

What I want is to replace the confirm method with this SweetAlert function

    swal({   
	title: "Are you sure?",   
	text: "You will not be able to recover this imaginary file!",  
	type: "warning", 
	showCancelButton: true,   
	confirmButtonColor: "#DD6B55",   
	confirmButtonText: "Yes, delete it!",   
	closeOnConfirm: false 
}, function(){   
	swal("Deleted!", "Your imaginary file has been deleted.", "success"); 
});

Anyone know how to do this, what happens when I try to place the sweetalert inside the onClick function is that the alert appears but it automatically delete the row without me having to confirm anything and the alert fades out.

I found the solution! 

$('.confirmation').click(function(e) {
e.preventDefault(); // Prevent the href from redirecting directly
var linkURL = $(this).attr("href");
warnBeforeRedirect(linkURL);
});

 function warnBeforeRedirect(linkURL) {
    swal({
      title: "Leave this site?", 
      text: "If you click 'OK', you will be redirected to " + linkURL, 
      type: "warning",
      showCancelButton: true
    }, function() {
      // Redirect the user
      window.location.href = linkURL;
    });
  }

I wrote this function:

function sweetConfirm(title, text) {
        event.preventDefault();
        var target = $(event.target);
        var href = null;
        var form = null;

        if (target.is("a")) href = target.attr("href");
        else if (target.is("button:submit")) form = target.closest("form");
        else if (target.is("button")) href = target.attr("href") || target.attr("value");

        swal({
            title: title,
            text: text,
            type: "warning",
            allowOutsideClick: true,
            showCancelButton: true
        }, function () {
            if (href) window.location.href = href;
            else if (form) form.submit();
        });
    }

sweetConfirm function will accept a submit button, link button or a normal button and will ask before do the action.

You can use it in the following scenarios:

<a type="button" class="btn btn-default" href="/" onclick="return sweetConfirm('Are you sure?')">
    Link Button 1
</a>

<button type="button" class="btn btn-default" href="/" onclick="return sweetConfirm('Are you sure?')">
    Link Button 2
</button>

<form action="/" method="DELETE">
    <input type="hidden" name="id" value="..">
    <button type="submit" class="btn btn-danger" onclick="return sweetConfirm('Are you sure?')">
        Delete
    </button>
</form>

Add event.preventDefault(); preventDefault();

      $('.confirmation').on('click', function (event) {
         event.preventDefault();
       swal({   
        title: "Are you sure?",   
        text: "You will not be able to recover this imaginary file!",  
        type: "warning", 
        showCancelButton: true,   
        confirmButtonColor: "#DD6B55",   
        confirmButtonText: "Yes, delete it!",   
        closeOnConfirm: false 
    }, function(){   
        swal("Deleted!", "Your imaginary file has been deleted.", "success"); 
    });

   });

I made this codepen in case anyone wants to debug. It appears this is working (check the browser console log for when 'done' is printed) http://codepen.io/connorjsmith/pen/YXvJoE

$('.confirmation').on('click', function(){
  swal({
    title: "Are you sure?",
    text: "You will not be able to recover this imaginary file!",
    type: "warning",
    showCancelButton: true,
    confirmButtonColor: "#DD6B55",
    confirmButtonText: "Yes, delete it!",
    cancelButtonText: "No, cancel plx!",
    closeOnConfirm: false,
    closeOnCancel: false
  },
  function(isConfirm){
    if (isConfirm) {
      console.log('done');
      swal("Deleted!", "Your imaginary file has been deleted.", "success");
    } else {
        swal("Cancelled", "Your imaginary file is safe :)", "error");
    }
  });
})

Try this code which is mentioned as in docs:

$('.confirmation').on('click', function () {
    swal({   
         title: "Are you sure?",   
         text: "You will not be able to recover this imaginary file!",  
         type: "warning", 
         showCancelButton: true,   
         confirmButtonColor: "#DD6B55",   
         confirmButtonText: "Yes, delete it!",   
         closeOnConfirm: false 
    }, function(isConfirm){   
           return isConfirm; //Will be either true or false
    });
});
