Hi everyone,
I have been using mochikit for a while with a lot of success (after
the initial frustrations of getting to grips with the weirdness of
javascript ;-), but today ran into a problem in Safari with the
function createDOM. Here is what it boils down to
<div id="mydiv">blah</div>
<script type="text/javascript">
mydiv = $(mydiv);
createDOM("div", {}, mydiv.childNodes);
</script>
fails in Safari with the following error
TypeError - Value undefined (result of expression node.apply) is not
object.
http://localhost/mochikit/MochiKit/DOM.js Line:323
Looking at that file it appears that the function coerceToDOM sees
mydiv.childNodes as a function rather than an array of nodes, hence
tries to apply this function without much success...
Indeed if I check typeof(mydiv.childNodes) I get "function".
My fix has been to change
mydiv.childNodes
to
map(null, mydiv.childNodes)
in order to coerce it into an iterable object. This works.
I have then two questions:
1. Was my expectation that the little script above should work
unfounded ? If so, why ?
2. Is there a better way to go around this problem ? Maybe the
coerceToDOM function should check for the existence of node.apply
before using it ?
Thanks for any help.
