I am using Jcrop on an image that is resized with css for uniformity.
JS
<script type="text/javascript">
$(window).load(function() {
//invoke Jcrop API and set options
var api = $.Jcrop('#image', { onSelect: storeCoords, trueSize: [w, h] });
api.disable(); //disable until ready to use
//enable the Jcrop on crop
button click
$('#crop').click(function() {
api.enable();
});
});
function storeCoords(c) {
$('#X').val(c.x);
$('#Y').val(c.y);
$('#W').val(c.w);
$('#H').val(c.h);
};
</script>
HTML
<body>
<img src="/path/to/image.jpg" id="image" class="img_class" alt="" />
<br />
<span id="crop" class="
button">Crop Photo</span>
<span id="#X" class="hidden"></span>
<span id="#Y" class="hidden"></span>
<span id="#W" class="hidden"></span>
<span id="#H" class="hidden"></span>
</body>
CSS
body { font-size: 13px; width: 500px; height: 500px; }
.image { width: 200px; height: 300px; }
.hidden { display: none; }
I need to set the h and w variables to the size of the actual image. I tried using the .clone() manipulator to make a copy of the image and then remove the class from the clone to get the sizing but it sets the variables to zeros.
var pic = $('#image').clone();
pic.removeClass('image');
var h = pic.height();
var w = pic.width();
It works if I append the image to an element in the page, but these are larger images and I would prefer not to be loading them as hidden images if there is a better way to do this. Also removing the class, setting the variables, and then re-adding the class was producing sporadic results.
I was hoping for something along the lines of:
$('#image').removeClass('image', function() {
h = $(this).height();
w = $(this).width();
}).addClass('image');
But the removeClass function doesn't work like that :P
