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
