html2canvas的问题

Question

I need to have the child image appear in a new division it places it outside the HTML tag and cuts off bottom on save any suggestions?

I was able to get Clone to work TY for that advise... But my upload is still missing app. 50 pixels from bottom of image ..... Still have not figured out how to return the image URL back and would like to get the clone to appear Directly under my generated image and not off page..... any advise on that?

          function screenshot(){
                html2canvas(document.getElementById("capture")).then(function(canvas) {   


                     var elmnt = document.getElementsByTagName("DIV")[2];
                     var cln = elmnt.cloneNode(true);
                     document.body.appendChild(cln);

                    // Get base64URL
                    var base64URL = canvas.toDataURL('image/jpg').replace('image/jpg', 'image/octet-stream');

                    // AJAX request
                    $.ajax({
                        url: 'ajaxfile.php',
                        type: 'post',
                        data: {image: base64URL},
                        success: function(data){
                            console.log('Upload successfully.');
                        }

                    });
                });
            }

Here is my ajaxfile

$image = $_POST['image'];

$location = "upload/";

$image_parts = explode(";base64,", $image);

$image_base64 = base64_decode($image_parts[1]);

date_default_timezone_set("America/Chicago");
$filename = date("m_j_y-H_i_s").'.png';

$file = $location . $filename;
$imageurl  = 'upload/'.$filename.'.png';


file_put_contents($file, $image_base64);

echo $filename;
echo $file;
echo $location;
echo $image;
