Hello,
I'm trying to use the drag and drop in my web app so that users can
reposition images in their album. But am not having much luck. I've
implemented as follows:
header stuff...
<script src="/js/prototype.js" type="text/javascript"></script>
<script src="/js/common.js" type="text/javascript"></script>
<script src="/js/albums.js" type="text/javascript"></script>
<script src="/js/lightbox.js" type="text/javascript"></script>
<script src="/js/scriptaculous.js?load=effects,dragdrop"
type="text/javascript"></script>
<body>
<ul id="album-images">
<style type="text/css">.images { width: 70px; height: 70px;
}</style>
<li class="images">
<img src="blahblah..." />
</li>
<li class="images">
</li>
</ul>
<script type="text/javascript">
Sortable.create(
"album-images",
{
dropOnEmpty: true,
containment: "album-images",
constraint: false
}
);
</script>
</body>
</html>
I am getting to the following error:
"element has no value dragdrop.js line 584"
which is at:
_findRootElement: function(element) {
It seems that the code is calling
create: function(element) {
element = $(element);
in "create:" and then calling, on line 592, in function options:
element = Sortable._findRootElement($(element));
so $( $( "album-images" ) ) which of course is null
If I work around this error, I get the same error in prototype.js.
Since no one else is having this problem, I assume that I have done
something wrong. I pulled the tarball 1.6.4 off the site just a few
days ago.
Thanks in advance for any help or ideas!!
