This seems to be working if the height of the browser is less..
Otherwise I can't click on the "submit" button after I crop the picture
Please help me what am I doing wrong. Here's the code:
$('#drop').on('click', function() {
$('#fileUpload').trigger('click');
});
$('#fileUpload').on('change', function(e) {
addImage(e.target);
});
$("#drop").on("dragover", function(e) {
e.preventDefault();
e.stopPropagation();
$(this).addClass('dragging');
});
$("#drop").on("dragleave", function(e) {
$(this).removeClass('dragging');
});
$("#drop").on("drop", function(e) {
e.preventDefault();
e.stopPropagation();
var data = e.dataTransfer || e.originalEvent.dataTransfer;
addImage(data);
});
function addImage(data) {
var file = data.files[0];
if (file.type.indexOf('image') === -1) {
alert('Sorry, the file you uploaded doesn\'t appear to be an image.');
return false;
}
var reader = new FileReader();
reader.onload = function(event) {
var img = new Image();
img.onload = function() {
if (img.width < 200 || img.height < 200) {
alert('Sorry, the image you uploaded doesn\'t appear to be large enough.');
return false;
}
cropImage(img);
}
img.src = event.target.result;
}
reader.readAsDataURL(file);
}
function cropImage(originalImage) {
$(originalImage).attr('id', 'fullImage');
$('#imageResize').html(originalImage);
$('#sectionDragAndDrop').addClass('hidden');
$('#sectionResize').removeClass('hidden');
var newImage = new imageCrop('#fullImage', 200, 200);
$('#crop').on('click', function() {
var results = newImage.crop();
$('#thumbnail').html(results.img);
$('#sectionResize').addClass('hidden');
$('#sectionThumbnail').removeClass('hidden');
});
}

This will work here but if the browser height is more than "submit" button is covered up by an overlay and we can't click on it..

You need to take the button out of the resize section
where the image is being added. You then need to edit your javascript wherever you see the hidden
class being toggled on #sectionResize
to include the same code on #crop
. See below or in this updated fiddle. Hope it helps!
