Ah, don't you love components with file upload? I'm back!
So I am using the hack that makes components work with file upload. My view
looks like this:
{{= form}}
<script>
$("#file-form input.upload").button(); // this uses jquery UI's button
routine
{{# hack because jquery.form.js does not properly pass headers}}
{{if response.flash:}}
$(".flash").hide().html('{{= XML(response.flash)}}').slideDown();
{{pass}}
{{if response.js:}}
eval('{{= XML(response.js)}}');
{{pass}}
{{# NOTE SINGLE QUOTES AROUND response.flash AND response.js ABOVE}}
</script>
response.flash and response.js are one-liners.
At initial load there are no problems. However, after form submission, I do
a return dict(form=form) and the above myfunction.load gets reloaded. At
this point, there's an error message in the FireBug console saying:
Uncaught ReferenceError: $ is not defined
and it points to the line $("#file-form input.upload").button();
There's another button that's passed in through the form and a script that
defines its button behavior, and that also gives the same error message.
Now, according to my research, this error message means that jQuery hasn't
been loaded. Of course, I did load jQuery way back at the beginning in my
layout.html file that's essentially being extended here, but under the
auspices of a load.
Nevertheless, the response.js is getting executed correctly and, on top of
that, the form does display correctly. So this isn't a killer, but it does
keep me awake at nights. Can any of you deep thinkers out there tell me
what's actually going on under the hood that's causing this issue, and how
to make it go away?
